Introducing a Group Therapy Program (PLAN D) for Young Outpatients with Derealization and Depersonalization: A Pilot Study.

Depersonalization and derealization (DD) cause significant distress and are associated with poor role and social functional outcomes. Despite the relatively high prevalence of DD symptoms and the chronic course in those suffering from a DD disorder, there still exists a need for effective interventions. Preliminary evidence indicates that cognitive behavioral therapy (CBT) delivered in an individual setting demonstrates some positive intervention effects for patients with DD regarding their symptom levels. By considering DD-specific treatment needs, a group therapy program was developed as an add-on therapy based on CBT techniques called PLAN D comprising the following elements: psychoeducation, lifestyle interventions, acceptance and mindfulness training, and new patterns of DD-related cognitions. In a pilot study, we present an 8-week group intervention for adolescents and young adults with DD disorder. To our knowledge, no standardized group intervention program for DD exists so far. Thus, this novel intervention represents a promising opportunity to positively influence long-term outcomes and course of DD.
