Acceptance and commitment therapy (ACT) is a form of psychotherapy based on relational frame theory and behavioral analysis. It teaches clients to accept unwanted private events like thoughts and feelings rather than trying to control them. The core principles of ACT include cognitive defusion, acceptance, contact with the present moment, observing the self, discovering values, and committed action. A study assessed using ACT over 8 sessions for delusions in addition to treatment as usual. It aimed to build acceptance, willingness, values, and defusion and hypothesized it would decrease distress, delusional conviction, and anxiety levels from baselines.
