APA (the American Psychological Association) requires specific formatting for the use of the ampersand (&) in any APA-style paper. Find specifications for the use of ampersands in citations of sources and in references in "The Publication Manual of the American Psychological Association." Writers must cite sources for theories, ideas, and research with or without a direct quote. The Publication Manual provides guidelines for citing books, journal articles, lectures, URLs, websites and other sources.

Cite every source used in your manuscript: articles, books, lectures, websites and digital object identifiers (DOIs), whether you have a direct quotation or not.
Use the ampersand when you have more than one author in a citation and you set it off parenthetically. For example, some researchers (Campbell, Matthews, & Goodson, 2009) found significant results.
