Mindfulness-based cognitive Therapy (MBCT) has shown to be effective in the relapse prevention and treatment of several psychiatric disorders. However, MBCT has not yet been applied in OCD (Obsessive-compulsive Disorder). This article pro- poses an adaptation of the eight-session group program for patients with residual symptoms af- ter cognitive behavioural treatment (CBT) with exposure. It has proven feasible and was consider- ed helpful by patients within the framework of a pilot study [1]. Apart from an overview of the modified manual, OCD-specific elements are presented in detail and illustrated on the base of work sheets. The manual indicates that MBCT could be a useful supplement to CBT and is well applicable to the therapeutic needs of patients with OCD.
