Your approach to citing the book will depend on whether the book was entirely written by the same author(s) or if the book is a collection of chapters by different authors.
When all the chapters in a book were written by the same author(s), the in-text citations direct readers to the specific locations of paraphrases or quotations, and therefore it's the entire book that is listed in the references, not a specific chapter. See How Do I Reference a Book in APA Style? for information and examples.
If you're working with a book that is comprised of chapters by different authors, each chapter is treated as a separate resource in the references. These books typically list one or more editors to indicate who brought the chapters together to create the book. Please see How Do I Reference a Chapter of an Edited Book in APA Style? for information and examples.
