Researchers and clinicians working with Obsessive-Compulsive Disorders (OCD) and related disorders who need the most current information available will find this volume of great use. This work covers contemporary theory, research, and treatment of the various subtypes of OCD and problems often referred to as OCD spectrum disorders.

As the mental health field considers the next iteration of the DSM, an entire research agenda is being planned to elucidate issues such as how best to understand and classify OCD. The questions of subtypes and spectrum disorders are at the heart of this issue and will guide how OCD is conceptualized in DSM-V. This volume, dedicated to such diagnostic, theoretical, and treatment issues, helps informs the field of the most up-to-date knowledge and what remains to be resolved.

• Deconstructs OCD into its subtypes
• Reviews current research and treatment for these problems
• Considers how OCD will be conceptualized in DSM-V
• Represents an international scope with contributions from field experts in psychology, psychiatry, and social work
• Includes critical discussion of the OCD subtype and OCD spectrum concepts

I am a cognitive-behavioral psychologist. I treat primarily individuals with anxiety disorders, across all ages. Most of my interests focus on the widespread applicability and acceptance of cognitive and behavioral methods to a wide variety of problems in the treatment community.

My research has been primarily in the following areas, with brief descriptions:

Obsessive-compulsive disorder (OCD)

In general, I have been interested in the nature and treatment of OCD.  This has included maintaining factors, subtypes, assessment of severity, and general and specific cognitive factors in the condition, for children and adults with the disorder.  Some recent efforts include participation in a multi-site examination of the hereditability of obsessive-compulsive subtype symptoms, magical ideation in OCD, and treatment procedures for different subtypes.

Anxiety Disorders

Closely related to the work on OCD, my interest in anxiety disorders has also been concerned with maintaining factors and issues in cognitive-behavioral treatment.  One general aspect, anxiety sensitivity, has been a focus of attention.

Disgust in anxiety disorders

Disgust is an understudied emotion.  I have been actively investigating the role of disgust in phobias and contamination fear. 

Virtual Reality Treatment

Most recently, computer directed treatment, using virtual reality, has been an area of investigation, particularly for public speaking fear.
