Answer:

Reiger DA, Farmer ME, Roe DS, Locke BZ, Keith SJ, and Judd LL. "Comorbidity of Mental Disorders with Alcohol and Other Drug Abuse: Results from the Epidemiolocal Catch Area (ECA) Study." JAMA 264 (1990): 254.

Commentary:

Firstly, because the writer included the names of all the authors, he/she would not have to include the "et al." at the end of the author section.

Secondly, put the title of the article in quotation marks and capitalize all important words in the title.

Thirdly, italicize the name of the publication, and put volume number information right after the publication name.

Finally, put the year of publication in parentheses.
