This book investigates the clinical mechanisms of Generalized Anxiety Disorder (GAD) and provides a structured framework for reducing chronic worry through evidence-based psychological intervention. The authors, Michelle G. Craske and David H. Barlow, are prominent researchers in the field of clinical psychology who utilize the principles of Cognitive Behavioral Therapy (CBT) to address pathological anxiety. They present a systematic program designed to help individuals identify, challenge, and modify the cognitive and behavioral patterns that sustain excessive worry. The text serves as a clinical manual for both practitioners and patients seeking to implement proven therapeutic strategies.

Experts recognize this work as a foundational resource within the 'Treatments That Work' series, frequently citing its utility in clinical settings.
