Abstract
Background
The recommended psychological treatment of choice for obsessive-compulsive disorder (OCD) is exposure with response prevention (ERP). Although this treatment is quite effective, recovery rates are modest and attrition rate is relatively high. Also, ERP treatment requires amounts of therapist time. A possible way to improve OCD treatment is by taking into account key cognitive processes involved in the development and maintenance of the disorder. The metacognitive model is such an account and pilot findings suggest that the associated metacognitive therapy (MCT) might be an effective treatment for OCD.
Methods
In the present study, a randomized controlled trial (RCT) is used to assess the effectiveness of MCT in comparison to ERP in an outpatient clinical sample of patients with OCD.
Results
Both MCT and ERP produced significant pre-treatment to post-treatment decreases in obsessive-compulsive, comorbid psychological symptoms and metacognitive beliefs, both with moderate to large within-group effect sizes and high proportions of significant clinical change. Drop-out rates were low and treatment gains were maintained at six-month follow-up. There were no differences in efficacy observed between MCT and ERP treatments.
期刊介绍：
Journal of Obsessive-Compulsive and Related Disorders (JOCRD) is an international journal that publishes high quality research and clinically-oriented articles dealing with all aspects of obsessive-compulsive disorder (OCD) and related conditions (OC spectrum disorders; e.g., trichotillomania, hoarding, body dysmorphic disorder). The journal invites studies of clinical and non-clinical (i.e., student) samples of all age groups from the fields of psychiatry, psychology, neuroscience, and other medical and health sciences. The journal''s broad focus encompasses classification, assessment, psychological and psychiatric treatment, prevention, psychopathology, neurobiology and genetics. Clinical reports (descriptions of innovative treatment methods) and book reviews on all aspects of OCD-related disorders will be considered, as will theoretical and review articles that make valuable contributions.
Suitable topics for manuscripts include:
-The boundaries of OCD and relationships with OC spectrum disorders
-Validation of assessments of obsessive-compulsive and related phenomena
-OCD symptoms in diverse social and cultural contexts
-Studies of neurobiological and genetic factors in OCD and related conditions
-Experimental and descriptive psychopathology and epidemiological studies
-Studies on relationships among cognitive and behavioral variables in OCD and related disorders
-Interpersonal aspects of OCD and related disorders
-Evaluation of psychological and psychiatric treatment and prevention programs, and predictors of outcome.
