What are headings?

Headings, sections, subsections, or levels of subordination are a style of dividing your research paper into major parts, then minor subsections. Most college papers do not need headings, especially if you are only producing two to five pages. However, if your professor requests you use headings or your are writing an especially long or detailed paper, then use headings to help readers navigate your text. Follow the APA style rules for creating the correct level of heading. Always start with a level one heading and drill down to the last subsection possible (five) in order as seen below. Instructions and examples for headings are available on p. 47- 49 of the new APA 7th Edition manual.

• Heading Levels Template: Student Paper APA Style 7th Edition This example student paper clearly illustrates how to style section headings including the paper title and the Introduction section (which should not be labeled Introduction as APA assumes all papers begin with an introduction section).

Proper Title Case vs. lowercase paragraph heading

Proper title case is using both uppercase and lowercase letters in a title. It calls for the major words to be capitalized while any small conjunctions are made smaller, i.e., 

The Title of this Paper is Lengthy

Lowercase paragraph heading calls for the first word to be capitalized along with any proper nouns contained within the heading, i.e., 

        The title of this heading is much shorter and all lowercase except for the first word.

7th Edition APA Style: How to Use APA Headings in Your Paper

APA headings and subheadings give your paper the structure it needs to differentiate and separate sections –  much like how we’ve structured this article.  Sounds simple, right? Not exactly. 

Like a reference list, in-text citations, footnotes, and abstract, APA headings require correct formatting. More so since the American Psychological Association (APA) released the 7th edition of their style guide. 

In this article, we’ll go through the different APA heading levels and their formats. You will also have access to APA headings examples and insight on  APA capitalization rules  so you can nail APA heading formatting without breaking a sweat. 

Table of Contents

What Are APA Headers? 

As mentioned earlier, APA headers separate and differentiate your paper’s sections. They are crucial in scholarly works because: 

• They give structure to your report. 
• Readers and your adviser or restructure can quickly identify the sections of your paper. 
• When properly formatted and used, they can provide a visual aid to improve the flow of information in your paper. 

The APA headers are divided into five levels (more on this later!).

APA 6th Edition vs. 7th Edition: Is There A Difference In Headings?  

Before diving down to APA’s unique headings system, let’s talk about the elephant in the room – the style guide edition. And, we hate to break it to you. There are a lot of changes between the APA 6th edition vs. 7th edition, but since we’re only talking about headings, we’re not going to outline all the differences. 

Luckily for you, there are not a lot of changes in the APA style 7th edition headings. 

• For the capitalization and style, you should write the headings in title case and boldface. 
• Formatting of the first level (main level of heading) and second level headings are almost identical to the 6th edition, except for the new title case and boldface rules. 
• The third, fourth, and fifth-level headings of the 7th edition APA are distinguished by using periods, indentation, and italics. 

To better understand these changes, you can refer to the table below.  

In addition to these formatting changes, the 7th APA style guide also dictates that student papers do not need a running head.

What Are the Different APA Heading Levels? 

Now that you know what APA headings are and the difference between the headings of APA 6th and 7th editions, let’s talk about the levels. 

APA headings levels are divided into five – Level 1, Level 2, Level 3, Level 4, and Level 5. In a hurry? You can check the comparison table below.

Expert Insight:  Title case means capitalizing the first letter of words with at least four or more letters. These words are typically proper nouns, pronouns, adverbs, nouns, and adjectives. However, keep in mind that the first word in a header is always in upper case, even if the first word is an article like “ the”  or  “a.”

Level 1 

Level 1, or the first level of heading, represents the main section of your paper. For instance, if your paper topic discusses the effects of social media platforms on university students, the header “Method” should be in level 1. 

In a 7th APA style, the structure should be:

The text after Level 1 will be a new paragraph and not on the same line as the heading. 

Expert Insight:  Does the Level 1 format look familiar? That’s because it has the same structure as the Paper Title element (APA 7 title page) in the APA cover page format.

What if the next portion of your paper discusses the sampling method you’ve used? In that case, the first level of subsection should be the second level of headings or simply Level 2. Why? This is because the “sampling method” is a cluster of the main level “Method.”

The structure of a Level 2 header is, however, different. Instead of having the “Sampling Method” centered, you’ll flush it to the left. A Level 2 header will be in bold, and the paragraph will start in a new line. 

Here’s how a Level 2 APA is formatted:

Tip:  When in doubt, remember that APA sub-headings or subsections should be related to the subsequent header.

Level 3 

The third level of headings, or Level 3, further expounds the information you’ve shared in Level 2 or “Sampling Method.” In this case, your level 3 will be “Procedure.”The formatting of Level 2 and Level 3 are pretty similar.

As a matter of fact, there is one key difference a Level 3 header will be in bold italic. The alignment, boldface, and title case will remain the same. 

You should format a Level 3 APA header like this:

Level 4 

You will need to use the fourth level of headings or Level 4 if there are other details from the Level 3 “Sampling Method” that you need to discuss further. In our APA example, that Level 4 will be the “Participant Recruitment.”

The format of Level 4 is distinct from levels 1, 2, and 3 because: 

• It is indented. 
• The paragraph is in line with the heading. 
• You will add a period at the end of the heading. 

To better understand an APA Level 4 heading format, here is an example:

You’ve probably caught on that Level 5 is a subheading of Level 4, and you are correct! If “Participant Recruitment” warrants more information, you can use the fifth level of headings for either “Tools” or “Compensation.”

The formatting of Level 5 is a bit similar to Level 4; the only difference is that you’ll use a boldface italic. Other elements like indent and period will remain the same. 

APA Heading Examples 

If you combine the levels, your paper should look like this:

How to Choose the Right APA Heading to Use?

With five levels to choose from, selecting which one you should use for your paper can be daunting. Here are some tips: 

• Use the Level 1 APA header when it is an important part of the paper. For instance, method, conclusion, and results. 
• Use the Level 2 heading when the subsections are related to the first level. 
• You should apply a Level 3 header when the APA subheadings are related to Level 2. 
• Level 4 headers should be used in your paper if the sections are directly correlated with Level 3. 
• Lastly, you should use Level 5 headers when the information is related to Level 4. 

How Do You Organize Headings in APA 7? 

Now that you are familiar with all the five-level headings in APA 7. The question now is, how do you arrange them? The rule of thumb for organizing APA 7 headers is to always start with Level 1, followed by subsequent headings of equal importance. 

Does that mean that the levels should only be used once? Not technically. You can have all the number of levels in a section as long as you follow the progression, wherein Level 1 always comes first. 

Tip:  Don’t mistake section labels and APA headings or vice versa. Section labels or special headings are different from regular headings. Not only are they formatted differently, but they also appear at the top section of the paper, below the pagination or page number. You will always find them at the start of a new page. 

Additional APA 7 Header Guidelines 

On top of the format or structure of the level headers, you should also watch out for the following: 

• Text, including the headers, should be double-spaced.
• Font size and typeface should stay consistent throughout your article. For instance, if you’ve used Times New Roman 12pt in your headers, the text should also have the same typeface and size. 
• Depending on your teacher’s requirements, you may or may not need labels (letter or number) for the headers. When in doubt, ask for clarification. 
• There should be at least two APA subheadings in your paper. If you only have one, consider adding more sections in your paper or use no subheadings at all. 

APA Headings FAQ

How to create table of contents in apa format.

In APA 7th edition, it is not required to have a table of contents, but in case your adviser requires one, you can easily do so whether you are using Google docs or Microsoft Word. 

In Google Docs: 

• Set the headers in the correct header size. Click the “Normal Text” dropdown and choose Header 1 for Level 1 APA headings, Header 2 for Level 2, and so on. 
• Go to Insert>Table of Contents. 

Note:  Keep in mind that APA 7th style guide dictates that the headings and text should have the same font size and typeface. So, after printing the table of contents, make sure to revert the levels to the correct size. 

In Microsoft Word: 

• Highlight the level heading 
• Select Update the Heading
• Match the heading size with the level heading. For instance, if you have a Level 1 Header, select Header 1. 
• Go to References > Table of Contents > Custom Table of Contents.  
• Input how many headings you will need. 

Tip:  Ensure you set the levels in the correct format before creating the table of contents. All levels no longer have a lower case heading. The only thing you should watch out for is the alignment, boldface, italics, and period.

Do You Have to Use All the APA Headers?

No, you don’t have to use all five APA headers in your paper. The headers and the number of subsections will highly depend on your writing style and subject matter. 

Is There an Introduction Heading? 

No, there isn’t an “introduction heading.” This is because the first paragraphs of a paper are already understood as the introduction section. 

Heading in the Right Direction 

The format of APA headings and subheadings can be confusing at first. But remember, APA capitalization rules for the 7th APA edition mean using title case for all heading levels; no more uppercase and lowercase headings. And you can distinguish the third, fourth, and fifth-level headings through italicization, period, and indentation. As for the text after the heading, only levels 4 and 5 will have the paragraph in line with the headings. 

Don’t forget that running headers are no longer required in student papers! But just to be on the safe side, make sure to always ask your instructor.

Headings are used to effectively organize ideas within a study or manuscript.  It can also highlight important items, themes or topics within sections.  By creating concise headings, the reader can anticipate key points and track the development of your argument.  The heading levels establish the hierarchy of each section and are designated by their formatting.

Adapted from American Psychological Association. (2009). Format for Five Levels of Heading in APA Journals. Publication manual of the American psychological association (6th ed., p. 62) Washington, D.C.: American Psychological Association.

• If you need to use subsections in any given section, use a least two, otherwise omit their use.
• Do not label headings with numbers or letters
• Use of title case : Use of both upper and lower case letters, all major words are capitalized
• Paragraph headings are immediately followed by text for that subsection, rather than starting on a new line.  The heading sits at the start of the first paragraph for that section.

• Comprehensive Guide to Headings and Subheadings in APA 7.0

Section 1: Introduction to Headings and Subheadings in APA 7.0-

In academic writing, the use of headings and subheadings is crucial for organizing and structuring a paper. APA (American Psychological Association) style, specifically in its 7th edition, provides clear guidelines on how to effectively use headings and subheadings to enhance readability and comprehensibility of research papers, essays, and other scholarly works. This section will provide a comprehensive introduction to the importance, purpose, and benefits of using headings and subheadings in APA 7.0 format.

Purpose of Headings and Subheadings

Headings and subheadings serve as visual cues to help readers navigate through the content of a paper. They create a hierarchical structure, indicating the relationships between different sections and subsections, and aid in organizing ideas and presenting information in a logical manner. By using headings and subheadings, writers can effectively divide their work into manageable and coherent sections, making it easier for readers to comprehend and follow the main arguments and supporting details.

Importance of Headings and Subheadings

Clear and well-structured headings and subheadings are essential in academic writing for several reasons. First and foremost, they enhance the overall readability of the paper by breaking down the text into smaller, digestible chunks. This organization allows readers to quickly identify and locate specific information, especially when they are scanning or skimming through the document.

Secondly, headings and subheadings contribute to the coherence and flow of the paper. By providing a clear roadmap, they guide the reader through the main ideas, supporting evidence, and key points presented in each section. This not only improves the overall structure of the paper but also helps maintain the logical progression of thoughts and arguments.

Additionally, headings and subheadings assist both readers and writers in comprehending complex topics. They enable writers to organize their thoughts, ensuring that each section focuses on a specific aspect or theme. This organization facilitates a deeper understanding of the subject matter for both the writer during the drafting process and the reader during the consumption of the paper.

Formatting Guidelines for Headings and Subheadings

APA 7.0 provides specific rules and formatting guidelines for using headings and subheadings. These guidelines include the use of different levels of headings, capitalization rules, and placement within the paper. Understanding and adhering to these guidelines is crucial for maintaining consistency and conformity with APA style.

The APA 7.0 formatting guidelines for headings and subheadings are based on a five-level hierarchy, with each level indicating the level of importance and hierarchy of information. Level 1 headings are the highest level, followed by Level 2, Level 3, and so on. Each level has a specific formatting style, such as font size, boldness, and indentation, to differentiate it from the other levels. Furthermore, APA 7.0 also provides guidance on the appropriate use of sentence case, title case, and capitalization in headings and subheadings. For instance, Level 1 headings are typically written in sentence case and are centered and bolded. Level 2 headings are aligned to the left margin, bolded, and written in title case. To maintain clarity and consistency, APA 7.0 also provides recommendations on the number of headings to use within a paper. It suggests that at least two headings should be used in any given section, as a single heading alone may not adequately represent the content covered.

Section 2: The Purpose and Importance of Headings and Subheadings in APA 7.0

Facilitating information retrieval.

One of the primary purposes of headings and subheadings in APA 7.0 is to facilitate information retrieval for readers. When faced with a lengthy document, readers often engage in scanning or skimming techniques to locate specific information or sections of interest. Well-structured headings and subheadings act as signposts, allowing readers to quickly identify the content they are seeking without having to read the entire text. By providing a clear and organized hierarchy, headings guide readers to the main sections of a paper, while subheadings further break down the content into more specific subsections. This hierarchical structure enables readers to navigate the document with ease, locating relevant information efficiently. Thus, headings and subheadings in APA 7.0 contribute significantly to the overall accessibility and user-friendliness of academic papers.

Enhancing Readability and Comprehensibility

Headings and subheadings play a vital role in enhancing the readability and comprehensibility of academic writing. They help break up large blocks of text into smaller, digestible sections, preventing the overwhelming feeling that dense paragraphs can create. By visually separating different sections and subsections, headings and subheadings allow readers to mentally prepare for the content they are about to encounter. Additionally, headings and subheadings improve the flow and coherence of a paper. They provide a roadmap for readers, helping them understand the organization and structure of the author's arguments and supporting evidence. Well-crafted headings and subheadings enable readers to follow the logical progression of ideas and maintain a clear understanding of the paper's main points. Finally, headings and subheadings aid in the comprehension of complex topics. By breaking down the content into smaller, focused sections, readers can grasp the material more easily. Headings act as cognitive cues, preparing readers for the information presented in each section. This approach not only facilitates understanding but also allows readers to engage with the content at a deeper level, promoting knowledge retention.

Organizing and Structuring Ideas

Headings and subheadings in APA 7.0 serve as valuable tools for organizing and structuring ideas within a paper. They help writers divide their work into meaningful sections, each addressing a specific aspect or theme related to the overall topic. This organization ensures that information is presented in a coherent and logical manner, making it easier for both the writer and the reader to navigate the paper.

By using headings and subheadings, writers can create a clear outline for their work, ensuring that each section has a distinct focus. This outline acts as a framework, guiding the writer in presenting their arguments and supporting evidence in a systematic and organized way. Writers can use headings to delineate major sections or main ideas, while subheadings allow for further subcategorization and exploration of subtopics.

Furthermore, headings and subheadings assist writers in structuring their thoughts during the writing process. By providing a visual representation of the paper's organization, headings help writers maintain a coherent flow of ideas and prevent the inclusion of irrelevant or tangential information. This structured approach not only improves the overall quality of the paper but also enhances the writer's ability to communicate their ideas effectively.

Conveying the Hierarchical Relationship of Information

Another important purpose of headings and subheadings in APA 7.0 is to convey the hierarchical relationship of information. By assigning different levels to headings, the writer can indicate the relative importance and order of ideas within the paper. Higher-level headings represent broader themes or major sections, while lower-level headings address more specific subtopics or subsections. This hierarchical structure helps readers understand the organization and logical flow of the paper at a glance. It allows them to grasp the overall structure and the relationships between different sections without having to read the entire document. Additionally, the use of indentation and formatting styles for each level of heading further reinforces the hierarchical relationship and aids in visual differentiation.

Section 3: Formatting Guidelines for Headings and Subheadings in APA 7.0

Proper formatting of headings and subheadings is crucial in APA 7.0 style to ensure consistency, clarity, and readability in academic writing. This section will delve into the specific formatting guidelines provided by APA 7.0 for headings and subheadings, including the use of different levels, capitalization rules, and placement within the paper.

Levels of Headings

APA 7.0 introduces a five-level hierarchy for headings, each denoting a different level of importance and significance within the paper. These levels provide a structured framework for organizing the content and help readers understand the organization and flow of ideas. Here are the five headings in APA 7.0:

Level 1: Centered, Bold and Title Case

            Text begins here.

Level 2: Left-Aligned, Bold and Title Case

Level 3: Left-Aligned, Bold, Italics, and Title Case

Level 4: Left-Aligned, Bold, Title Case, and Period. Text begins here.

Level 5: Left-Aligned, Bold, Title Case, Italics, and Period . Text begins here.

Section 4: Organizing and Structuring Your Paper

Using headings and subheadings in apa 7.0.

Organizing and structuring your paper effectively is crucial for presenting your ideas in a logical and coherent manner. Headings and subheadings in APA 7.0 play a vital role in achieving this goal by providing a clear framework for organizing your content. This section will delve into strategies and best practices for utilizing headings and subheadings to organize and structure your paper in accordance with APA 7.0 guidelines.

Preparing an Outline

Before you begin writing your paper, it is helpful to create an outline that outlines the main sections and subsections you intend to cover. An outline acts as a roadmap, allowing you to visualize the overall structure and flow of your paper. It serves as a foundation for developing meaningful headings and subheadings that accurately represent the content and facilitate logical organization. Start by identifying the major sections that your paper will include, such as introduction, literature review, methods, results, discussion, and conclusion. These major sections will serve as Level 1 headings in APA 7.0. Next, break down each major section into subsections that address specific subtopics or aspects related to the main theme. These subsections will be represented by Level 2 headings. Depending on the complexity and depth of your paper, you may further divide the subsections into sub-subsections using Level 3, Level 4, and Level 5 headings. Creating a comprehensive outline not only helps you organize your thoughts but also ensures that you cover all the necessary components of your paper. It allows you to see the relationships between different sections and subsections, enabling you to present your arguments and evidence in a logical and coherent sequence.

Maintaining Consistency and Parallelism

Consistency is key when it comes to organizing and structuring your paper using headings and subheadings. It is important to establish a consistent framework that is followed throughout the entire document. Consistency ensures that readers can easily understand the hierarchy and relationships between different sections and subsections. When creating headings and subheadings, aim for parallelism in terms of grammatical structure and formatting. Parallelism means that headings at the same level should have a similar grammatical structure and formatting style. For instance, if you choose to use noun phrases for Level 2 headings, maintain this pattern consistently across all Level 2 headings in your paper. This helps readers navigate through the content smoothly and maintain a sense of coherence. Furthermore, parallelism extends to the use of punctuation and capitalization within headings and subheadings. Maintain consistent capitalization rules, such as sentence case for Level 1 headings and title case for Level 2 headings. This uniformity enhances the visual hierarchy and clarity of your paper.

Balancing Depth and Granularity

Effective organization and structuring involve finding the right balance between depth and granularity in your headings and subheadings. Level 1 headings represent major sections and should encapsulate broad themes or concepts, providing an overview of what will be discussed within each section. Level 2 headings, as subsections, delve into more specific topics or aspects related to the main theme of the major section.

Reviewing and Revising the Organization

Organizing and structuring your paper using headings and subheadings is not a one-time task. It is an iterative process that requires regular review and revision to ensure optimal clarity and coherence. Once you have completed the initial draft of your paper, review the organization of your headings and subheadings. Ask yourself if the structure effectively reflects the flow of your ideas and supports your main argument. Consider whether the headings accurately represent the content of each section and subsection. During the review process, pay attention to transitions between sections and subsections. Ensure that the headings and subheadings create a smooth transition from one topic to another, guiding readers through the logical progression of your paper. If you notice any gaps or inconsistencies, revise and refine the organization accordingly. Additionally, seek feedback from peers, mentors, or instructors. Their fresh perspective can provide valuable insights into the clarity and effectiveness of your headings and subheadings. Incorporate their feedback and make necessary adjustments to improve the overall organization and structure of your paper.

Section 5: Common Mistakes to Avoid in Using Headings and Subheadings in APA 7.0

While using headings and subheadings in APA 7.0 can greatly improve the organization and readability of your paper, it's important to be aware of common mistakes that can compromise the effectiveness of your headings. By understanding and avoiding these mistakes, you can ensure that your headings enhance the clarity and coherence of your academic writing. This section will explore some common mistakes to avoid when using headings and subheadings in APA 7.0.

Inconsistent Formatting

One of the most common mistakes is inconsistent formatting of headings and subheadings. In APA 7.0, it is crucial to maintain consistency in capitalization, alignment, and formatting styles across headings at the same level. Inconsistencies can confuse readers and disrupt the visual hierarchy of your paper. Ensure that all Level 1 headings have the same formatting, all Level 2 headings have the same formatting, and so on. Consistency in formatting contributes to the overall professionalism and readability of your work.

Poor Alignment and Spacing

Another mistake to avoid is incorrect alignment and spacing of headings and subheadings. In APA 7.0, Level 1 headings are centered and typically start on a new page or a new line with an extra line space before and after the heading. Level 2 headings and lower-level headings, however, are left-aligned and generally require an extra line space before the heading but not after. Failure to align and space headings correctly can create confusion and disrupt the logical flow of your paper. Review APA 7.0 guidelines carefully to ensure proper alignment and spacing of your headings.

Lack of Parallelism

Parallelism, or consistent grammatical structure, is crucial when using headings and subheadings. Headings at the same level should follow a similar structure to maintain coherence and readability. For example, if you use noun phrases for Level 2 headings, ensure that all Level 2 headings follow this pattern. Lack of parallelism can make your headings appear disjointed and may confuse readers. Consistently apply parallel structure within each level of headings to create a smooth and organized flow of information.

Overcomplicating the Heading Structure

While it is important to provide a clear and hierarchical structure to your paper, overcomplicating the heading structure can lead to confusion and excessive fragmentation. Strive to find a balance between providing enough detail to cover your content effectively and avoiding an excessive number of headings and subheadings. Each heading should represent a meaningful subdivision and contribute to the overall organization and coherence of your paper. Aim for a clear and concise heading structure that guides readers without overwhelming them with excessive levels or overly specific subdivisions.

Lack of Descriptiveness

Headings and subheadings should be descriptive and informative to accurately represent the content covered within each section. Avoid using generic or ambiguous headings that do not provide a clear indication of what readers can expect to find. Vague headings can leave readers uncertain about the content or make it challenging to locate specific information within your paper. Ensure that your headings succinctly capture the main ideas or themes of each section, guiding readers through your content effectively.

Ignoring the Reader's Perspective

When creating headings and subheadings, it's important to consider the perspective of your readers. Put yourself in their shoes and think about how your headings will facilitate their understanding and navigation through your paper. Consider whether your headings effectively communicate the main points, guide readers through the logical flow of your arguments, and enable them to locate specific information easily. Ignoring the reader's perspective can result in headings that are unclear, unhelpful, or inconsistent, hindering the overall readability and comprehension of your work.

Neglecting to Revise and Edit Headings

Headings should not be an afterthought or treated as static elements in your paper. Neglecting to revise and edit your headings can lead to inaccuracies, lack of clarity, or poor alignment with the final content of your paper. As you progress through the writing process, continuously review and refine your headings to ensure they accurately represent the content and flow of your arguments. Make necessary adjustments, reword headings for better clarity, and ensure that they align with the finalized structure and organization of your paper.

APA Style is the most common writing style used in college and career. Its purpose is to promote excellence in communication by helping writers create clear, precise, and inclusive sentences with a straightforward scholarly tone. It addresses areas of writing such as how to

• format a paper so it looks professional;
• credit other people’s words and ideas via citations and references to avoid plagiarism; and
• describe other people with dignity and respect using inclusive, bias-free language.

APA Style is primarily used in the behavioral sciences, which are subjects related to people, such as psychology, education, and nursing. It is also used by students in business, engineering, communications, and other classes. Students use it to write academic essays and research papers in college, and professionals use it to conduct, report, and publish scientific research.

In addition, APA Style provides you with a powerful tool that will hep you avoid deliberate or unintentional plagiarism. Please review the Avoiding Plagiarism Guide created by the APA experts to understand what two common types of plagiarism are and how to avoid them. 

Why is learning citations important? Citations help readers understand where the information used in your paper comes from, enabling them to trace the path of that information. When readers wish to explore a specific point or reference cited in the text, citations make it easier by providing information about your sources in a standardized format.

Besides showing readers where you obtained information, using citations also has a strong ethical purpose. In academic writing, it is important to credit ideas that are not your own. Citations allow you to integrate the ideas of others with your own thoughts in a fair and honest way.

The reference formats for APA Style manuals are as follows:

APA Style provides a foundation for effective scholarly communication because it helps authors present their ideas in a clear and concise, and organized manner.  Uniformity and consistency enable readers to (a) focus on the ideas being presented rather than formatting and (b) scan works quickly for key points, findings, and sources. When style works best, ideas flow logically, sources are credited appropriately, and papers are organized predictably and consistently. 

Students are encouraged to first learn about APA Style by reading works written in APA Style. A couple of guides created by APA experts from the American Psychological Association can help you with that:

Anatomy of a Journal Article   https://apastyle.apa.org/instructional-aids/anatomy-journal-article.pdf

Scholarly journal articles share a common anatomy or structure. Each part of an article serves a specific purpose. The handout of  Anatomy of a Journal Article explains how journal articles are structured and how to become more efficient at reading and understanding them. Understanding the structure of a scholarly article and the purpose of each part helps you grasp a strategy called targeted reading. Targeted reading means to read specific sections of research articles first to determine if the article seems useful for your research topic. This way you will save time, find useful article faster, and choose which articles to read in full.

Reading and Understanding Abstracts https://apastyle.apa.org/instructional-aids/reading-abstracts.pdf

Abstracts are short summaries of scientific research articles. The handout of Reading & Understanding Abstracts explains the definition and purpose of abstracts and the benefits of reading them, including analysis of a sample abstract. The skill of reading and understanding abstracts of scholarly articles not only saves time but also helps you conduct better research and write more effectively.

APA Style Writing Principles https://apastyle.apa.org/instructional-aids/writing-principles.pdf

The poster created by APA experts shows the three main principles of APA Style: clarity, precision, and inclusion and lists steps on how to achieve them. As a student writer, you always should write your academic paper with clarity, precision, and inclusion. 

Research Article Activity https://apastyle.apa.org/instructional-aids/apa-style-research-activity.pdf

Reading research articles is not an easy task for you as a student. The Research Article Activity designed by APA Style experts aims to make it easy to read and understand a scholarly article. This activity worksheet helps you find, cite, analyze, and summarize a research article. Completing this activity breaks down a lengthy research article into easily understandable chunks. This way helps you better understand the study in the article before you write about it.

How to Write an APA Methods Section | With Examples

Published on February 5, 2021 by Pritha Bhandari . Revised on June 22, 2023.

The methods section of an APA style paper is where you report in detail how you performed your study. Research papers in the social and natural sciences often follow APA style. This article focuses on reporting quantitative research methods .

In your APA methods section, you should report enough information to understand and replicate your study, including detailed information on the sample , measures, and procedures used.

Example of an APA methods section

Other interesting articles, frequently asked questions about writing an apa methods section.

The main heading of “Methods” should be centered, boldfaced, and capitalized. Subheadings within this section are left-aligned, boldfaced, and in title case. You can also add lower level headings within these subsections, as long as they follow APA heading styles .

To structure your methods section, you can use the subheadings of “Participants,” “Materials,” and “Procedures.” These headings are not mandatory—aim to organize your methods section using subheadings that make sense for your specific study.

Note that not all of these topics will necessarily be relevant for your study. For example, if you didn’t need to consider outlier removal or ways of assigning participants to different conditions, you don’t have to report these steps.

The APA also provides specific reporting guidelines for different types of research design. These tell you exactly what you need to report for longitudinal designs , replication studies, experimental designs , and so on. If your study uses a combination design, consult APA guidelines for mixed methods studies.

Detailed descriptions of procedures that don’t fit into your main text can be placed in supplemental materials (for example, the exact instructions and tasks given to participants, the full analytical strategy including software code, or additional figures and tables).

Prevent plagiarism. Run a free check.

Begin the methods section by reporting sample characteristics, sampling procedures, and the sample size.

Participant or subject characteristics

When discussing people who participate in research, descriptive terms like “participants,” “subjects” and “respondents” can be used. For non-human animal research, “subjects” is more appropriate.

Specify all relevant demographic characteristics of your participants. This may include their age, sex, ethnic or racial group, gender identity, education level, and socioeconomic status. Depending on your study topic, other characteristics like educational or immigration status or language preference may also be relevant.

Be sure to report these characteristics as precisely as possible. This helps the reader understand how far your results may be generalized to other people.

The APA guidelines emphasize writing about participants using bias-free language , so it’s necessary to use inclusive and appropriate terms.

Sampling procedures

Outline how the participants were selected and all inclusion and exclusion criteria applied. Appropriately identify the sampling procedure used. For example, you should only label a sample as random  if you had access to every member of the relevant population.

Of all the people invited to participate in your study, note the percentage that actually did (if you have this data). Additionally, report whether participants were self-selected, either by themselves or by their institutions (e.g., schools may submit student data for research purposes).

Identify any compensation (e.g., course credits or money) that was provided to participants, and mention any institutional review board approvals and ethical standards followed.

Sample size and power

Detail the sample size (per condition) and statistical power that you hoped to achieve, as well as any analyses you performed to determine these numbers.

It’s important to show that your study had enough statistical power to find effects if there were any to be found.

Additionally, state whether your final sample differed from the intended sample. Your interpretations of the study outcomes should be based only on your final sample rather than your intended sample.

Write up the tools and techniques that you used to measure relevant variables. Be as thorough as possible for a complete picture of your techniques.

Primary and secondary measures

Define the primary and secondary outcome measures that will help you answer your primary and secondary research questions.

Specify all instruments used in gathering these measurements and the construct that they measure. These instruments may include hardware, software, or tests, scales, and inventories.

• To cite hardware, indicate the model number and manufacturer.
• To cite common software (e.g., Qualtrics), state the full name along with the version number or the website URL .
• To cite tests, scales or inventories, reference its manual or the article it was published in. It’s also helpful to state the number of items and provide one or two example items.

Make sure to report the settings of (e.g., screen resolution) any specialized apparatus used.

For each instrument used, report measures of the following:

• Reliability : how consistently the method measures something, in terms of internal consistency or test-retest reliability.
• Validity : how precisely the method measures something, in terms of construct validity  or criterion validity .

Giving an example item or two for tests, questionnaires , and interviews is also helpful.

Describe any covariates—these are any additional variables that may explain or predict the outcomes.

Quality of measurements

Review all methods you used to assure the quality of your measurements.

These may include:

• training researchers to collect data reliably,
• using multiple people to assess (e.g., observe or code) the data,
• translation and back-translation of research materials,
• using pilot studies to test your materials on unrelated samples.

For data that’s subjectively coded (for example, classifying open-ended responses), report interrater reliability scores. This tells the reader how similarly each response was rated by multiple raters.

Report all of the procedures applied for administering the study, processing the data, and for planned data analyses.

Data collection methods and research design

Data collection methods refers to the general mode of the instruments: surveys, interviews, observations, focus groups, neuroimaging, cognitive tests, and so on. Summarize exactly how you collected the necessary data.

Describe all procedures you applied in administering surveys, tests, physical recordings, or imaging devices, with enough detail so that someone else can replicate your techniques. If your procedures are very complicated and require long descriptions (e.g., in neuroimaging studies), place these details in supplementary materials.

To report research design, note your overall framework for data collection and analysis. State whether you used an experimental, quasi-experimental, descriptive (observational), correlational, and/or longitudinal design. Also note whether a between-subjects or a within-subjects design was used.

For multi-group studies, report the following design and procedural details as well:

• how participants were assigned to different conditions (e.g., randomization),
• instructions given to the participants in each group,
• interventions for each group,
• the setting and length of each session(s).

Describe whether any masking was used to hide the condition assignment (e.g., placebo or medication condition) from participants or research administrators. Using masking in a multi-group study ensures internal validity by reducing research bias . Explain how this masking was applied and whether its effectiveness was assessed.

Participants were randomly assigned to a control or experimental condition. The survey was administered using Qualtrics (https://www.qualtrics.com). To begin, all participants were given the AAI and a demographics questionnaire to complete, followed by an unrelated filler task. In the control condition , participants completed a short general knowledge test immediately after the filler task. In the experimental condition, participants were asked to visualize themselves taking the test for 3 minutes before they actually did. For more details on the exact instructions and tasks given, see supplementary materials.

Data diagnostics

Outline all steps taken to scrutinize or process the data after collection.

This includes the following:

• Procedures for identifying and removing outliers
• Data transformations to normalize distributions
• Compensation strategies for overcoming missing values

To ensure high validity, you should provide enough detail for your reader to understand how and why you processed or transformed your raw data in these specific ways.

Analytic strategies

The methods section is also where you describe your statistical analysis procedures, but not their outcomes. Their outcomes are reported in the results section.

These procedures should be stated for all primary, secondary, and exploratory hypotheses. While primary and secondary hypotheses are based on a theoretical framework or past studies, exploratory hypotheses are guided by the data you’ve just collected.

This annotated example reports methods for a descriptive correlational survey on the relationship between religiosity and trust in science in the US. Hover over each part for explanation of what is included.

The sample included 879 adults aged between 18 and 28. More than half of the participants were women (56%), and all participants had completed at least 12 years of education. Ethics approval was obtained from the university board before recruitment began. Participants were recruited online through Amazon Mechanical Turk (MTurk; www.mturk.com). We selected for a geographically diverse sample within the Midwest of the US through an initial screening survey. Participants were paid USD $5 upon completion of the study.

A sample size of at least 783 was deemed necessary for detecting a correlation coefficient of ±.1, with a power level of 80% and a significance level of .05, using a sample size calculator (www.sample-size.net/correlation-sample-size/).

The primary outcome measures were the levels of religiosity and trust in science. Religiosity refers to involvement and belief in religious traditions, while trust in science represents confidence in scientists and scientific research outcomes. The secondary outcome measures were gender and parental education levels of participants and whether these characteristics predicted religiosity levels.

Religiosity

Religiosity was measured using the Centrality of Religiosity scale (Huber, 2003). The Likert scale is made up of 15 questions with five subscales of ideology, experience, intellect, public practice, and private practice. An example item is “How often do you experience situations in which you have the feeling that God or something divine intervenes in your life?” Participants were asked to indicate frequency of occurrence by selecting a response ranging from 1 (very often) to 5 (never). The internal consistency of the instrument is .83 (Huber & Huber, 2012).

Trust in Science

Trust in science was assessed using the General Trust in Science index (McCright, Dentzman, Charters & Dietz, 2013). Four Likert scale items were assessed on a scale from 1 (completely distrust) to 5 (completely trust). An example question asks “How much do you distrust or trust scientists to create knowledge that is unbiased and accurate?” Internal consistency was .8.

Potential participants were invited to participate in the survey online using Qualtrics (www.qualtrics.com). The survey consisted of multiple choice questions regarding demographic characteristics, the Centrality of Religiosity scale, an unrelated filler anagram task, and finally the General Trust in Science index. The filler task was included to avoid priming or demand characteristics, and an attention check was embedded within the religiosity scale. For full instructions and details of tasks, see supplementary materials.

For this correlational study , we assessed our primary hypothesis of a relationship between religiosity and trust in science using Pearson moment correlation coefficient. The statistical significance of the correlation coefficient was assessed using a t test. To test our secondary hypothesis of parental education levels and gender as predictors of religiosity, multiple linear regression analysis was used.

In your APA methods section , you should report detailed information on the participants, materials, and procedures used.

• Describe all relevant participant or subject characteristics, the sampling procedures used and the sample size and power .
• Define all primary and secondary measures and discuss the quality of measurements.
• Specify the data collection methods, the research design and data analysis strategy, including any steps taken to transform the data and statistical analyses.

You should report methods using the past tense , even if you haven’t completed your study at the time of writing. That’s because the methods section is intended to describe completed actions or research.

In a scientific paper, the methodology always comes after the introduction and before the results , discussion and conclusion . The same basic structure also applies to a thesis, dissertation , or research proposal .

Depending on the length and type of document, you might also include a literature review or theoretical framework before the methodology.

Formatting Research Paper Headings and Subheadings

Different style guides have different rules regarding the formatting of headings and subheadings in a paper, but what information you should actually put into your subheadings is a different question and often up to personal taste. Here we quickly summarize general guidelines, different approaches, and what not to do when choosing headings for a research paper.

Does it matter how I name my sections and subsections?

The main sections of a research paper have general headers and are often journal-specific, but some (e.g., the methods and discussion section) can really benefit from subsections with clear and informative headers. The things to keep in mind are thus the general style your paper is supposed to follow (e.g., APA, MLA), the specific guidelines the journal you want to submit to lists in their author instructions , and your personal style (e.g., how much information you want the reader to get from just reading your subsection headers). 

Table of Contents:

• How Should You Name Your Sections and Subsections?
• Avoid These Common Mistakes

Style Guides: Research Paper Heading and Subheading Format

Headers identify the content within the different sections of your paper and should be as descriptive and concise as possible. That is why the main sections of research articles always have the same or very similar headers ( Introduction, Methods, Results, Discussion ), with no or only small differences between journals. However, you also need to divide the content of some of these sections (e.g., the method section) into smaller subsections (e.g., Participants, Experimental Design, and Statistical Analysis ), and make sure you follow specific journal formatting styles when doing so. 

If the journal you submit to follows APA style , for example, you are allowed to use up to five levels of headings, depending on the length of your paper, the complexity of your work, and your personal preference. To clearly indicate how each subsection fits into the rest of the text, every header level has a different format – but note that headers are usually not numbered because the different formatting already reflects the text hierarchy.

APA style headings example structure

Level 1 Centered, Bold, Title Case

Text begins as a new paragraph.

Level 2 Left-aligned, Bold, Title Case

Level 3 Left-aligned, Bold Italic, Title Case

Level 4     Indented, Bold, Title Case, Period . Text begins on the same                    

                                 line and continues as a regular paragraph.

Level 5     Indented, Bold Italic, Title Case, Period. Text begins on the                           

                                 same line and continues as a regular paragraph.

If you only need one section header (e.g. Methods ) and one level of subsection headers (e.g., Participants, Experimental Design, and Statistical Analysis ), use Level 1 and Level 2 headers. If you need three levels of headings, use Levels 1, 2, and 3 (and so on). Do not skip levels or combine them in a different way. 

If you write a paper in Chicago style or MLA style , then you don’t need to follow such exact rules for headings and subheadings. Your structure just has to be consistent with the general formatting guidelines of both styles (12-pts Times New Roman font, double-spaced text, 0.5-inch indentation for every new paragraph) and consistent throughout your paper. Make sure the different formatting levels indicate a hierarchy (e.g., boldface for level 1 and italics for level 2, or a larger font size for level 1 and smaller font size for level 2). The main specifics regarding Chicago and MLA headings and subheadings are that they should be written in title case (major words capitalized, most minor words lowercase) and not end in a period. Both styles allow you, however, to number your sections and subsections, for example with an Arabic number and a period, followed by a space and then the section name. 

MLA paper headings example structure

1. Introduction

2. Material and Methods

2.1 Subject Recruitment

2.2 Experimental Procedure

2.3 Statistical Analysis

3.1 Experiment 1

3.2 Experiment 2

4. Discussion

5. Conclusion

What research paper headings do you need?

Your paper obviously needs to contain the main sections ( Introduction, Methods, Results, Discussion, and maybe Conclusion ) and you need to make sure that you name them according to the target journal style (have a look at the author guidelines if you are unsure what the journal style is). The differences between journals are subtle, but some want you to combine the results and discussion sections, for example, while others don’t want you to have a separate conclusion section. You also need to check whether the target journal has specific rules on subsections (or no subsections) within these main sections. The introduction section should usually not be subdivided (but some journals do not mind), while the method section, for example, always needs to have clear subsections.

How to Name Your Sections and Subsections

The method section subheadings should be short and descriptive, but how you subdivide this section depends on the structure you choose to present your work – which can be chronological (e.g., Experiment 1, Experiment 2 ) or follow your main topics (e.g., Visual Experiment, Behavioral Experiment, Questionnaire ). Have a look at this article on how to write the methods for a research paper if you need input on what the best structure for your work is. The method subheadings should only be keywords that tell the reader what information is following, not summaries or conclusions. That means that “ Subject Recruitment ” is a good methods section subheading, but “ Subjects Were Screened Using Questionnaires ” is not.  

The subheadings for the result section should then follow the general structure of your method section, but here you can choose what information you want to put in every subheading. Some authors keep it simple and just subdivide their result section into experiments or measures like the method section, but others use the headings to summarize their findings so that the reader is prepared for the details that follow. You could, for example, simply name your subsections “ Anxiety Levels ” and “ Social Behavior ,” if those are the measures you studied and explained in the method section. 

Or, you could provide the reader with a glimpse into the results of the analyses you are going to describe, and instead name these subsections “ Anxiety-Like Behaviors in Mutant Mice ” and “ Normal Social Behaviors in Mutant Mice .” While keeping headings short and simple is always a good idea, such mini-summaries can make your result section much clearer and easier to follow. Just make sure that the target journal you want to submit to does not have a rule against that. 

Common Heading and Subheading Mistakes 

Subheadings are not sentences.

If your heading reads like a full sentence, then you can most probably omit the verb or generally rephrase to shorten it. That also means a heading should not contain punctuation except maybe colons or question marks – definitely don’t put a period at the end, except when you have reached heading level 4 in the APA formatting style (see above) and the rules say so.  

Be consistent

Always check your numbering, for example for spaces and periods before and after numbers (e.g., 3.2. vs 3.2 ), because readability depends on such features. But also make sure that your headings are consistent in structure and content: Switching between short keyword headings (e.g., “ Experiment 2 ”) and summary headings (e.g., “ Mice Do not Recognize People ”) is confusing and never a good idea. Ideally, subheadings within a section all have a similar structure. If your first subsection is called “ Mice Do not Recognize People ,” then “ People Do not Recognize Mice” is a better subheader for the next subsection than “Do People Recognize Mice? ”, because consistency is more important in a research paper than creativity. 

Don’t overdo it

Not every paragraph or every argument needs a subheading. Only use subheadings within a bigger section if you have more than one point to make per heading level, and if subdividing the section really makes the structure clearer overall.

APA Headings and Seriation

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

APA (American Psychological Association) style is most commonly used to cite sources within the social sciences. This resource, revised according to the 6 th edition, second printing of the APA manual, offers examples for the general format of APA research papers, in-text citations, endnotes/footnotes, and the reference page. For more information, please consult the Publication Manual of the American Psychological Association , (6 th ed., 2 nd printing).

Note:  This page reflects APA 6, which is now out of date. It will remain online until 2021, but will not be updated. The equivalent APA 7 page can be found here .

APA Style uses a unique headings system to separate and classify paper sections. Headings are used to help guide the reader through a document. The levels are organized by levels of subordination, and each section of the paper should start with the highest level of heading. There are 5 heading levels in APA. The 6 th edition of the APA manual revises and simplifies previous heading guidelines. Regardless of the number of levels, always use the headings in order, beginning with level 1. The format of each level is illustrated below:

Thus, if the article has four sections, some of which have subsections and some of which don’t, use headings depending on the level of subordination. Section headings receive level one format. Subsections receive level two format. Subsections of subsections receive level three format. For example:

Method (Level 1)

Site of Study (Level 2)

Participant Population (Level 2)

Teachers. (Level 3)

Students. (Level 3)

Results (Level 1)

Spatial Ability (Level 2)

Test one. (Level 3)

Teachers with experience. (Level 4)

Teachers in training. (Level 4)

Test two. (Level 3)

Kinesthetic Ability (Level 2)

In APA Style, the Introduction section never gets a heading and headings are not indicated by letters or numbers. Levels of headings will depend upon the length and organization of your paper. Regardless, always begin with level one headings and proceed to level two, etc.

APA also allows for seriation in the body text to help authors organize and present key ideas. For lists where a specific order or numbered procedure is necessary, use an Arabic numeral directly proceeded by a period, such as:

• Move the navigation bar from the right to the left side of the OWL pages.
• Integrate branded graphics (the Writing Lab and OWL logos) into the text on the OWL homepage.
• Add a search box to every page of the OWL.
• Develop an OWL site map.
• Develop a three-tiered navigation system.

For lists that do not communicate hierarchical order or chronology, use bullets:

• "This version is easier to use."
• "Version two seems better organized."
• "It took me a few minutes to learn how to use this version, but after that, I felt more comfortable with it."

Authors may also use seriation for paragraph length text.

For seriation within sentences, authors may use letters:

Authors may also separate points with bullet lists:

• the OWL site map;
• integrating graphics with text on the OWL homepage;
• search boxes on all OWL pages except the orange OWL resources (that is pending; we do have a search page);
• moving the navigation bar to the left side of pages on all OWL resources except in the orange area (that is pending);
• piloting the first phase of the three-tiered navigation system, as illustrated in the new Engagement section.

If your bulleted list is part of the sentence and is not preceded by a colon, treat the bullets like a part of the sentence, adhering to standard capitalization and punctuation.

The purpose of tables and figures in documents is to enhance your readers' understanding of the information in the document. Most word processing software available today will allow you to create your own tables and figures, and even the most basic of word processors permit the embedding of images, thus enabling you to include tables and figures in almost any document.
