Technological advances in psychotherapy: implications for the assessment and treatment of obsessive compulsive disorder.

Obsessive compulsive disorder (OCD) is a prevalent and costly condition that causes significant functional impairment and reduced quality of life. Although treatments with demonstrated efficacy for OCD, such as cognitive behavior therapy and antidepressants, have existed for over three decades, many patients remain inadequately treated or untreated. Challenges encountered in the treatment of OCD include problems with homework compliance, frequent relapse, difficulties in simulating the spontaneous nature of intrusive thoughts, and infrequent treatment sessions. Accumulated research now indicates that computerized assessment and therapy tools can significantly improve the cost/time-effectiveness of conventional psychotherapeutic interventions for anxiety disorders such as OCD without impairing therapeutic progress and outcome. In this paper we examine the potential of such technology, address current challenges in the assessment and treatment of OCD, and provide a rationale for future research in the field. We outline the general utility of computer technology in psychotherapeutic interventions, critically evaluate the existing literature on computer-assisted assessment and treatment specific to OCD, as well as discuss potential implications of portable technology for OCD treatment delivery and outcomes.
