Abstract
While a range of pharmacological and psychosocial treatments exist for people with troubling psychosis, many individuals continue to experience distressing psychotic symptoms. It has been suggested that psychotic disorders could be well suited to treatment approaches that incorporate acceptance and mindfulness teaching, which aim to alter the person’s relationship to pervasive psychotic symptoms (e. g. distressing voices), rather than struggling to alter their content. Therefore, this review sought to evaluate studies in which Acceptance and Commitment Therapy or mindfulness meditation training have been applied to the treatment of psychosis. A limited mixture of case studies and controlled and uncontrolled trials were critically assessed. While many such studies lacked scientific rigor, it remained evident that clinical gains were made which appeared to be due to the use of acceptance and mindfulness based approaches. Reduced levels of believability in psychotic thoughts/hallucinations were probably the most consistent findings. However, further well-controlled studies are clearly required.
