Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Symptoms of schizophrenia have historically been treatment resistant despite advances in psychopharmacology. Acceptance and Commitment Therapy (ACT) has been shown through some preliminary research to be effective with psychotic symptoms (Bach \& Hayes, 2002). ACT is considered part of the "third wave of CBT" along with Dialectical Behavior Therapy (DBT; Linehan, 1993) and Mindfulness-based Cognitive Therapy (MBCT; Segal, Williams, \& Teasdale, 2001). The target of change in ACT is acceptance of symptoms as experiences that a person can have without experiencing distress, and while living a life in accordance with one's values. The current study assessed the effectiveness of ACT (8 sessions) for delusions. Participants received treatment as usual throughout the study. The intervention followed the protocol of ACT described in Hayes, Strosahl and Wilson (1999) in which treatment will consist of building acceptance, willingness, and commitment to change, clarifying values, defusion of thoughts and feelings, as well as defusion of self. These therapeutic aims attempted to be achieved by the practice of various exercises in and out of session as well as the discussion of various metaphors within session. It was hypothesized that participants will exhibit decreased distress due to delusions, decreased delusional conviction and a reduction of overall anxiety levels from participants' baselines.
