Acceptance and commitment therapy for psychosis and trauma: Improvement in psychiatric symptoms, emotion regulation, and treatment compliance following a brief group intervention

Objectives Acceptance and Commitment Therapy ( ACT ) has shown effectiveness for individuals with psychosis and individuals with a history of childhood trauma, but has not been investigated with people with psychosis who also have a history of childhood trauma. This study aims at determining the efficacy of a mindfulness‐based ACT with this clientele in diminishing psychiatric symptoms, trauma‐related symptoms, as well as in improving treatment adherence. Design and Methods Fifty participants meeting our inclusion criteria were recruited and randomized to take part in either 10 sessions of ACT group, or Treatment as Usual ( TAU ). Results Using RCT it was found that symptom severity, for both overall symptoms ( BPRS ) and anxiety ( GAD ), decreased over the course of the treatment, and participants' ability to regulate their emotional reactions (i.e., accept them) increased. The study also found that treatment engagement increased with regards to help‐seeking for those in the ACT group, compared with the TAU controls. Conclusions Acceptance and Commitment Therapy offered in a group appears a promising treatment for those with psychosis and history of trauma. Practitioner points To understand the benefits of ACT with those who suffer from psychosis and a history of trauma. To further the understanding of the effectiveness of ACT.
