Worry and its Psychological Disorders 
Theory, Assessment and Treatment

Anxiety-based disorders are among the most common mental health
problems experienced in the population today. Worry is a prominent
feature of most anxiety-based disorders including generalized
anxiety disorder, specific phobias, obsessive-compulsive disorder,
panic disorder, and post-traumatic stress disorder.

Written by international experts, Worry and its Psychological
Disorders offers an up-to-date and complete overview of worry
in a single volume. Divided into four sections, the book explores
the nature of worry, the assessment of worry, contemporary theories
of chronic and pathological worry, and the most recently developed
treatment methods. It includes in-depth reviews of new assessment
instruments and covers treatment methods such as Cognitive
Behavioural Therapy and Metacognitive Therapy. Useful case studies
are also included.

This important volume provides an invaluable resource for
clinical practitioners and researchers. It will also be of
relevance to those studying clinical or abnormal psychology at
advanced level.
