The investigators plan to study a novel approach to help manage the stress of parenting a child with OCD, thus facilitating more effective resistance to OCD family accommodation and supporting the child in fighting this difficult illness. The investigators will explore the role of group-based mindfulness-based skills training (P-MBST) in supporting parents of OCD-affected youth, in particular investigating the possibility that increased distress tolerance as a result of mindfulness practice may help parents reduce OCD accommodation.
