Acknowledgments
There are many people without whom this workbook would not have been possible. 
First, we wish to acknowledge those who were instrumental in developing and investi -
gating the treatments described in this book. Dr. Aaron T. Beck pioneered many of the 
cognitive strategies that are used throughout the world to treat anxiety, depression, and 
many other conditions. We are also indebted to Drs. Isaac Marks, S. Rachman, Joseph 
Wolpe, David Barlow, and others who helped to develop and study the exposure-based 
strategies that are now commonplace for the treatment of anxiety. We also acknowledge 
the important contributions of Drs. Richard Heimberg, Samuel Turner, Deborah Beidel, 
David M. Clark, and others who adapted these cognitive and behavioral methods for the 
treatment of social anxiety.
A special thank-you goes out to our colleagues, clients, and patients who provided 
many helpful suggestions over the years that informed this second edition of The Shyness 
and Social Anxiety Workbook . Finally, we wish to express our gratitude to the staff at New 
Harbinger Publications (including Carole Honeychurch, Matthew McKay, Catharine 
Sutker, Amy Shoup, Dorothy Smyk, and many others), who worked closely with us 
through all stages of developing, editing, and marketing this book.
