Restricting Environmental Stimulation (REST) to Enhance Cognitive Behavioral Treatment for Obsessive Compulsive Disorder With Schizotypal Personality Disorder
W. Rand Walker, Robert F. Freeman, and Daniel K. Christensen, Washington State University
Restricted Environmental Stimulation Therapy (REST) was used adjunctively in an imaginal exposure plus response prevention treatment for a subject with Obsessive-Compulsive Disorder (OCD) with comorbid Schizotypal Personality Disorder. An audio loop tape was used as the eliciting stimuli during exposure to REST. Psycholphysiological measures and self reports indicated a substantial reduction of arousal to fear-evoking stimuli, as well as a marked reduction in OCD symptoms. Additionally, imaginal ability and attention to the task appeared to improve in the REST versus non-REST condition in this data-based single case report. Restricted environmental stimulation may enhance the effectiveness of imaginal exposure in patients with treatment refractory OCD.
