The basic APA format for citing an article is:
Author, Initial. Initial. (Year).
Title of article. Journal Title,
See the Notes in the box below this one.
Example: an article with one author:
Bolger, N. (1990). Coping as a
personality process: A prospective study. Journal of
Personality and Social Psychology, 59(3), 525-537.
An article with more than one author:
Duckworth, A. L., Quinn, P. D., & Tsukayama, E.
(2012). What No Child Left Behind leaves behind: The
roles of IQ and self-control in predicting standardized
achievement test scores and report card grades.
Journal of Educational Psychology, 104(2), 439-451.
An article with more than seven authors (this one was written by nine people):
Javaras, K. N., Schaefer, S. M., van Reekum, C. M., Lapate,
R. C., Greichar, L. L., Bachhuber, D. R., ... Davidson,
R. J. (2012). Conscientiousness predicts greater
recovery from negative emotion. Emotion, 12(5),
An article where the database doesn't provide a DOI:
Larsen, J. M. (1975). Effects of increased teacher support
on young children's learning. Child Development, 46(3),
631-637. Retrieved from http://www.jstor.org
(In this example, I'm citing JSTOR rather than the journal's actual homepage because the journal's homepage only includes articles from 1990 onward and this article was published in 1975. If I really wanted to go the extra mile, I could look up the article in CrossRef and find out that it actually does have a DOI assigned.)
To cite a book chapter, follow this basic format:
Author, Initial. Initial. (Year). Title of chapter. In Editors
of book (Eds.), Book title (pages of chapter).
Pastel R. H., Ritchie E. C. (1996). Mitigation of
psychological effects of weapons of mass
destruction. In: Ritchie E. L., Watson P. J.,
Friedman M. J. (Eds.), Interventions following
mass violence and disasters: strategies for
mental health practice (pp. 300-318). Guilford
