In this media edition of their book, Barlow and Durand continue to offer a unique integrative approach that helps readers understand how each disorder is determined by multiple forces (biological, psychological, cultural, social, familial, and environmental). The free companion CD-ROM allows readers to interact with the content of the book and enter an interactive learning environment where they can highlight text electronically, take notes, add their own links, and explore the full range of multimedia elements all in one easy-to-use interface.
