APA Style

The most common citaiton style in the social sciences is that of the American Psychological Association.  The basic citation forms are:

Journal Article:


Author, A. A., Author, B. B., & Author, C. C. (Year). Title of article. Title of Periodical, volume number(issue number), pages.


Atkinson, M., & Gianani, R. (2009). The pancreas in human type 1 diabetes: Providing new answers to age-old questions. Current Opinion in Endocrinology, Diabetes & Obesity, 16(4), 279-285.




Author, A. A. (Year of publication). Title of work: Capital letter also for subtitle. Location: Publisher.


Bray, G. A., & Bouchard, C. (2004). Handbook of obesity: Etiology and pathophysiology. New York: Marcel Dekker.


Try to locate as much information as you can. The author can the the agency that produced the site or an individual. Look around on the page for a last modified date to use as the date. If none is available, use (n.d.) where the date usually goes.


Author, A. A., & Author, B. B. (Date of publication). Title of document. Retrieved from http://Web address

ADA Style

In terms of citation style, the Journal of the American Dietitic Association's Guide for Authors states:

"The Journal follows the AMA Manual of Style, 10th ed, for references. One exception is that reference citations in the Journal must list all authors' names; use of "et al" is not acceptable. Abbreviate periodical titles according to the US National Library of Medicine's lists of biographic data found at: If a title does not appear on this list, provide the complete title. Published and updated dates, if available, and access dates for Web sites cited must be included. For example: Smith J. Risk factors for cancer. Cancer Risk Factors Web site. Published December 1, 2000. Updated January 15, 2008. Accessed February 1, 2008."

Some things to note about the AMA style that makes it different from APA:

  1. The lack of commas between the authors last name and first name initials.
  2. The use of abreviated journal titles.  A list of journal abreviations can be found by searching the National Library of Medicine's journal database at
  3. The position of the year of publication after the journal title, but before the volume number. Also, note the use of the semi-colon between the year and the volume number.
  4. Also note the lack of spaces between the year, volume and page numbers.

Here are some examples:

Journal Article:

K, Ith M, Kreis R, Faeh D, Bortolotti M, Tran C, Boesch C, Tappy L. Fructose overconsumption causes dyslipidemia and ecopic lipis deposition in healthy subjects with and without a family history of type 2 diabetes. Am J Clin Nutr. 2009;89:1760-1765.
