Cognitive therapy for compulsive checking in obsessive-compulsive disorder: A pilot trial.

We evaluated a novel, empirically-based cognitive therapy for compulsive checking - a common form of obsessive-compulsive disorder. Twelve adults completed 12 sessions of the therapy. Significant reductions in checking-related symptoms were found pre- to post-treatment, and pre-treatment to 6-month follow-up (moderate to large effect sizes). Participants reported high treatment acceptability after the third session, which was maintained at post-treatment. This pilot trial provides preliminary support for treating compulsive checking using this novel cognitive approach.
