Through Durand, Barlow, and Hofmann�s Essentials of Abnormal Psychology, you'll 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, and real case profiles provide a realistic context for the scientific findings. These features show you the real people behind the DSM-5 criteria, the theories, and the research.
