APA style is the format used by publications of the American Psychological Association. Most papers written for classes in the social sciences use APA style; some instructors in other disciplines also prefer APA format.

Quotations
When you use the author’s exact words, even for a short phrase, you must identify the material as a quote and include the exact location of the quote.
(Terrell & Watson, 2018, p. 149)
(Olsen, 2017, When to Change section);
(Olsen, 2017, para. 2);
(Expert Vagabond, 2016, 1:04).
A direct quote of fewer than 40 words begins and ends with quotation marks and should be incorporated into the text:
Ablon (1971) stated that the wave of emigration from American Samoa began in 1951, when the U.S. Navy “closed the naval base at Pago Pago on the major island of Tutuila” (p. 71).
A direct quote of 40 words or more begins on a new line, is indented half an inch from the left-hand margin, and does not use quotation marks:
According to Ablon (1971), the population of American Samoa dropped dramatically as a result of a wave of emigration following the withdrawal of the Navy from Pago Pago in 1951:
Many Samoan naval personnel and their dependents were then moved to Honolulu and from there to the West Coast cities in the late 1950’s. Many of these naval personnel have since retired and their families have remained in California. Other Samoans who are currently in the various branches of the service are based in California cities where their wives and children establish homes and reside during their tours of duty. (p. 77)
To omit unnecessary wording within a quote, use an ellipsis; to add material within a quote, use brackets:
According to James (2017), “Dishonesty . . . is never [emphasis added] acceptable.”
Using Source Material:
References Page
The list of References begins on a new page. Center the title References in bold at the top of the page. The page should be double-spaced, and entries should use a hanging indent (the first line of each entry begins at the margin, but the second and all subsequent lines are indented an additional half inch.)
List the references in alphabetical order by the authors’ last names; alphabetize unsigned articles by the first word of the title (except for A, An, and The).
Each entry should contain the author, the date, the title, and the source.
Authors’ Names
List authors by last name, followed by a comma and the authors’ initials. For sources with two to twenty authors, include the names of all the authors, using an ampersand (&) before the final name:
Marcek, V. I., Lewis, M. J., & Han, H.
For sources with more than twenty authors, list the first nineteen names, followed by an ellipsis, followed by the final author’s name:
Abbot, A., Ross, L. B., Toma, J. J., Fresquez, M., French, P. F., Stoll, G. D., Schram, M., Eisen, I. F., Nelson, A. B., Tannen, B., Entwhistle, B. J., Tredwell, P. E., Thrisk, N. S., Fiorelli, G., Feldman, R. S., Stuyvesant, P., Southworth, R., Ellington, D., Nordyke, L. N., . . . Takahashi, M.
Dates
Place dates in parentheses after the authors’ names. For journal articles, use only the year; for other sources begin with the year, followed by a comma and the month and day.
Titles
Use sentence case capitalization for titles of works on the references list; that is, capitalize the first letter of the first word, the first word after a colon, and proper nouns. Use italics for titles of self-contained works (such as books, webpages, and plays).
Sources
The source for a self-contained work (such as a book) is the publisher. The source for a short work contained within a longer work (such as an article in a periodical) is usually the title and publication information for the longer work in which it appears. The source for a webpage is the name of the website, which should be written in title case without italics; omit the source if the name of the website is the same as the name of the author.

Hoarding Disorder: What It Is, Who Is Affected, and How It Can Be Treated
No one likes to think about neighbors, friends or loved ones living in the midst of excessive clutter, and, worse yet, being hurt because
they simply have too much stuff. But a number of unexpected risks are associated with hoarding disorder (HD), and more people live with the
disorder than most people realize.
Definition
What is hoarding disorder? Wheaton et al. (2012) defined it as a compulsion to acquire goods combined with an inability to get rid of them,
to the extent that the hoarder’s use of their living space is impaired, and their functioning within that space is also impaired. The hoarder acquires
an abnormal quantity of goods in variety of ways; in one study a majority of women identified shopping as their primary means of accumulating
goods, “whereas men were more likely to report collecting free items and stealing” (Kress et al., 2016, p. 84). Having acquired the items, the
hoarder refuses to get rid of them, often demonstrating an inability to distinguish between the valuable and the worthless, difficulty in decision
making, and a high level of anxiety or even grief when an object must be thrown away (Gilliam & Tolin, 2010). The hoarder fills up their living
space, sometimes to the extent that they must creep around the house on trails through stacks of furniture, appliances, boxes, papers, and
garbage; in extreme cases there is no longer room to perform everyday household functions (Gilliam & Tolin, 2010).
HD as a Compulsive Disorder
Because the person with HD feels a compulsion to acquire objects and is obsessively attached to them, the condition was formerly
considered a type of obsessive-compulsive disorder (OCD; “When Keeping,” 2011). It differs from OCD, however, in some important ways, mainly
in that people with OCD tend to be aware of their dysfunction, while people with HD commonly don’t feel that there is anything wrong with their
behavior (Gilliam & Tolin, 2010).
