Proper APA format for sources with three to six authors requires listing the last names of all authors the first time you cite the source as well as the publication date. ...results indicated a strong positive correlation between the two variables (Robsen, Hutchkins, Ru, & Selanis, 1989).
General Rules for APA Format. Authors should be alphabetized by the last name of the first author of each work. If you want to cite multiple articles by the same author, list entries in chronological order from earliest to most recent. If there is no author given, begin your citation with the name of the primary source/article.
