The 10 chapters of this second edition of The Anxiety and Worry Workbook by David A. Clark and Aaron T. Beck were completely rewritten from the first edition, with updated material on cognitive-behavioral treatment  (CBT) of generalized anxiety, social anxiety, panic, and worry.  New chapters on healthy anxiety and anxiety sensitivity were added, as well as exercies on recovery-oriented exposure and the expectancy violation effect based on inhibited learning theory.  The workbook takes a more transdiagnostic approach to understanding anxiety and its treatment, with instruction and worksheets on how to distinguish between healthy and unhealthy forms of anxiety.  It also incorporates ideas from a newer form of CBT known as recovery-oriented cognitive therapy (CT-R).  This workbook draws heavily on the knowledge and wisdom of Dr. Beck who passed away in the latter months of writing this revision.  No doubt this workbook is one of Dr. Beck's final contributions on the treatment of anxiety.
