In this briefer version of Durand and Barlow’s widely taught text, the authors explain abnormal psychology through their standard-setting integrative approachuthe most modern, scientifically valid method for studying the subject. Through this integrative approach, students learn that psychological disorders are rarely caused by a single influence, but rooted in the interaction among multiple factors: biological, psychological, cultural, social, familial, and even political. A conversational writing style, consistent pedagogy, video clips of real clients (located on the accompanying Abnormal Psychology Live 2.5 CD-ROM), and real case profilesu95 percent from the authors’ own case filesuprovide a realistic context for the scientific findings of the book. In addition, these features ensure that readers never lose sight of the fact that real people are beyond the DSM-IV-TR criteria, the theories, and the research.
