Q. How do you cite an author with a name that uses an abbreviation in APA?

According to the APA Manual you should “Use commas to separate authors, to separate surnames and initials, and to separate initials and suffixes”  (p. 184).  For example:

Esbensen, F. A., Winfree, L. T., Jr., He, N., & Taylor, J. T. (2001). Youth gangs and definitional issues: When is a gang a gang and why does it matter? In Esbensen, F. A., Tibbetts, S. G., & Gaines, L. K (Eds.), American youth gangs at the millennium. Long Grove, IL: Waveland Press.
