APA 6 Format and Citation Guide Made Easy

The APA 6 guide was developed in line with the American Psychological Association in 2013. Publication manual of the American Psychological Association (6th ed.). Washington, DC: Author.

General Principles of APA 6 Formatting

  • Double-spacing throughout the paper.
  • Margins – 1″ (2.54 cm), while paper size should be 8.5″ x 11″
  • Times New Roman or Arial 12 pt. font (unless the instructions require a different font)

APA 6 papers contain running head(s) at the top of every page and page number. Page numbers are inserted flush right, while the paper’s title, written in UPPER CASE, is inserted flush left. Your title in the header should contain no more than 50 characters (including spaces and punctuation).

Papers written in APA  6 are divided into four sections:

  • Title Page
  • Abstract
  • Body
  • Reference List

Title Page

Running head: THE TITLE (with words’ Running head’ only on the title page)

All the following pages have a different header from the first page: THE TITLE

Title:

Your title should be inserted in the upper half of the first page.

You should not use more than 12 words for your title.

Use upper and lower case (avoid abbreviations and redundant words).

The title page should be double-spaced.

Insert the author’s name below the title.

Insert the educational institution below the author’s name.

The image elaborates the APA 6 cover page layout.

Abstract

  • The abstract is written on a new page; this page should contain a page header (see above).
  • The word “Abstract” is centered on the new page. Do not use quotation marks, bold, italics, or any other formatting.
  • The text on the abstract page is NOT indented.
  • The abstract should contain only the most relevant information, such as research topic/thesis statement, research question(s), sample size/participants, research design/method, data analysis, results, and conclusions.
  • The abstract consists of a single paragraph (about 130-150 words) of double-spaced text.
  • If keywords are required, they are indented and written beneath the abstract paragraph. Do not forget to use italics for the word “Keywords.”

Headings

  • Level 1 heading should be Bold, Uppercase, and Lowercase
  • Level 2 should be Left-aligned, Bold, Uppercase, and Lowercase
  • Level 3 should be indented, with a bold lowercase heading with a period. Begin your text after the period.
  • Level 4 should be indented, bold, italicized, and lowercase heading with a period. Begin your text after the period.
  • Level 5 indented, italicized, lowercase heading with a period. When writing, begin your text after the period.
The image highlights the heading levels layout in APA 6 format.

Reference List

The reference list is inserted at the end of your paper; any source you use must be included in the reference page and cited in the text.

Indent all lines after the first line in the entry (hanging indent); the lines should be indented one-half inch (1.27 cm) from the left margin of your paper.

  • Do not forget to invert authors’ names, such as last name and initials. Example: Cage, D. C.
  • If you have to cite more than seven authors, only the first six authors are listed, then an ellipsis is placed, and the last author’s name is listed after the ellipsis.
  • The reference list is always alphabetized by the first word in the reference entry (from A to Z).
  • When alphabetizing titles or group names as authors, go by the first significant word (disregard a, an, the, etc.)
  • If your reference has a group author, the name of the group can sometimes be abbreviated in the text—for example, the American Psychological Association can be abbreviated to APA. As with other abbreviations, spell out the name of the group upon first mention in the text and then provide the abbreviation.

If the name of the group first appears in parentheses in an in-text citation, put the abbreviation in brackets after it, followed by a comma and the year for the citation:

Example: The American Psychological Association (APA, 2011) suggested that parents talk to their children about family finances in age-appropriate ways.

Children should learn about family finances in age-appropriate ways (American Psychological Association [APA], 2011).

In the reference list entry, do not include the abbreviation for the group author. Instead, spell out the full name of the group.

Correct reference entry:

American Psychological Association. (2011). Dollars and sense: Talking to your children about the economy. Retrieved from http://www.apa.org/helpcenter/children-economy.aspx

Incorrect reference entry:

American Psychological Association (APA). (2011). Dollars and sense: Talking to your children about the economy. Retrieved from http://www.apa.org/helpcenter/children-economy.aspx

  • Journal titles are always presented in full and capitalized:

Example: Archives of General Psychiatry

  • Do not alter the journal’s name:

Example: JAMA Psychiatry (NOT Jama Psychiatry)

Personal communication is not included in the reference list. Instead, when citing information from an email, cite the source of information in parentheses.

Example:

(K. Dawson, personal communication, April 24, 2010).

Citing Governmental Sources

Government publication

Example:

United States Congress House Committee on Energy and Commerce. (2017). DOE for the 21st century: Science, environment, and national security missions (E&C Publication No. 114–119). Washington, DC: U.S. Government Publishing Office.

APA 6 In-text citations

When citing references in a text using the APA format, focus on the author-date approach. This means that the author’s surname (without suffixes such as Dr. or Jr.) appears in the text, followed by the year of publication.

Direct quotations require the inclusion of the page number in addition to the authors’ names and years.

Example: (Leary, 2009, p. 137).

An author named in a signal phrase

APA format requires the use of the word and instead of the ampersand before the last author’s name when citing a work by multiple authors in the text.

Example: Greene and Kernis (2012) argued that every individual involved in the process of creation of software is responsible for its quality.

The author is not named in a signal phrase.

Example: The framework based on categorizing racial attributes does not consider numerous individual differences between ethnic groups (Holland, 2010).

A work by two authors

Example: The use of sterilization accounts for 3.2 percent of birth control methods in Christian communities (Purnell & Paulanka, 2016).

A work by three to five authors

List all authors the first time a work is cited in the text. However, in subsequent citations, only the first author’s name, followed by et al., along with the year of publication, should be placed.

Example: The limitations of the classification system preclude its use for the determination of specific health needs of ethnic minorities (Flatman, Flemming, & Drewett, 2009).

Example: Belonging to a racial group requires a differentiation between racial needs and those of the society at large (Flatman et al., 2009).

Six or more authors

Include only the name of the first author, followed by et al., along with the year of publication.

Example: Baxter et al. (2014) argued that statewide statistics do not reflect the real experiences of Muslims in the U.S.

Unknown author

When the source does not identify an author, cite it by the first few words of its title. The titles of books and periodicals have to be italicized, whereas titles of book chapters and articles must be placed inside quotation marks.

Example: Naturalism and the improvement of healthcare outcomes are the main principles of the provision of biomedicine in the U.S. (Biomedicine and Health Care, 2015).

Example: The healthcare services in Australia are based on the long-standing culture of nursing as well as national models of health and illness (“Health care approaches,” 2011).

Corporate Author

If the name of the group first appears in parentheses (as in the second example below), put the abbreviation in brackets after it, followed by a comma and the year for the citation:

Example: The American Psychological Association (APA, 2011) suggested that parents talk to their children about family finances in age-appropriate ways.

Example: Children should learn about family finances in age-appropriate ways (American Psychological Association [APA], 2011).

In the reference list entry, do not include the group author’s abbreviation. Instead, spell out the group’s full name.

Authors with the same last name

Include first initials followed by the last names in order to distinguish between authors with the same last name.

For example, The religious and spiritual beliefs of Arab American Muslims significantly influence their healthcare practices and health-seeking behaviors (M. Berndt, 2016; L. Berndt, 2016).

More than one work by the same author in the same year

Distinguish between works by the same author in the same year by including lowercase letters next to the year of publication in both in-text citations and reference list entries.

Example: Terminally ill patients find a source of strength in performing daily prayers and adhering to other religious duties described in their sacred texts such as the Bible and Quran (Robbins, 2011a).

Indirect sources

Provide the author of the source in a signal phrase and include a citation of the secondary source in parentheses. Note that only the secondary source has to be included in the reference list.

Example: Smith argues that “personalistic systems provide the most accurate representation of a patient’s identity” (as cited in Wescot, 2014, p. 213).

Citing sources without page numbers

When an electronic document has numbered paragraphs, use the abbreviation “para.” followed by the paragraph number (Hall, 2001, para. 5). If the paragraphs are not numbered and the document includes

headings, provide the appropriate heading, and specify the paragraph under that heading.

Example: Pinker and Smith (2013) went so far as to argue “that Chinese cultures condone the use of invasive health care procedures” (para. 11).

Example: According to Smith (1997) (Mind Over Matter section, 2018, para. 6)

FAQs

What’s the difference between APA 6th and 7th editions?

The 7th edition, released in 2019, introduced several changes, including simplified author guidelines (listing up to 20 authors in the reference list), updated guidelines for digital sources, increased flexibility in font choices, and a new format for student papers.
However, many institutions still use the 6th edition, so always check which version is required.

How do I cite a source with no author?

When a source has no author, use the title of the work in place of the author’s name:
In-text citation: (“Article Title”, 2020)
Reference list: Article title. (Year). Publication Name. URL

Can I use first-person pronouns in APA style?

APA 6th Edition allows the use of first-person pronouns (I, we) in appropriate contexts, such as describing your research process or stating your position. However, use them sparingly and maintain a professional tone.

How do I cite multiple works by the same author in the same year?

When citing multiple works by the same author published in the same year, use lowercase letters (a, b, c) after the year to differentiate:
In-text: (Smith, 2020a; Smith, 2020b)
Reference list: Smith, A. (2020a). First article title… Smith, A. (2020b). Second article title…

How do I format an appendix in APA 6th Edition?

To format an appendix:
1) Start each appendix on a new page after your references
2) Label it “Appendix” (for a single appendix) or “Appendix A,” “Appendix B,” etc. (for multiple appendices)
3) Center the label at the top of the page
4) On the next line, provide a descriptive title (centered, bold)
5) Include the appendix content below the title
