HABIT REVERSAL TRAINING FOR OCD 2 Abstract Although exposure and response prevention (ERP) is currently the most effective treatment for obsessive-compulsive disorder (OCD), there are substantial refusal and dropout rates. Therefore, there is a critical need to find ways to make treatments for OCD more acceptable and increase efficacy. This report presents four patients with OCD who received a novel treatment, Habit Reversal Training (HRT). HRT is the treatment of choice for OCD-related disorders such as Trichotillomania, but has not been formally tested for OCD.
