Cognitive therapy for psychosis has progressed from case studies, treatment manuals, and pilot randomised controlled trials to fully powered and methodologically rigorous efficacy and, later, effectiveness trials. The interventions’ benefits have been confirmed by reviews and meta-analyses. Following careful consideration by government and professional organizations, it is now included in international treatment guidelines for schizophrenia. Psychosis strikes people in their prime, causing significant disruptions in their distress, well-being, and functioning, as well as significant societal costs. Early intervention has the potential to reduce the high relapse rates that occur after recovery from the first episode, as well as the ensuing morbidity and premature mortality associated with psychosis.
