Inpatient Group Acceptance and Commitment Therapy (ACT) for Psychosis Spectrum Disorder

The pilot study that will serve as the basis for the larger project - a multicenter randomized controlled single-blinded trial (RCT) will focus on testing the feasibility and efficacy of an inpatient group ACT treatment program and its effects on symptom severity and patient satisfaction in patients with psychosis spectrum disorder. The ACT-specific treatment program for inpatients with psychosis spectrum disorder is designed to enable patients to deal with their disease in an accepting manner over the long term, to promote self-determined and positive attitudes toward treatment and support options, and thus to reduce rehospitalization rates.
