Q. Citing chapters of a dissertation in APA Style

APA Style (7th ed.)

Since one person wrote the dissertation, you don't need to break out the chapters because your in-text citations will point people to the relevant sections of the text. Accordingly, you only need to reference the dissertation, versus referencing specific chapters within the dissertation.
