Aim: We aimed to systematically review the evidence of the effectiveness of family interventions for caregivers of people with recent‐onset psychosis compared with usual psychiatric care. A secondary objective was to directly compare the effects of different types of family interventions. Methods: MEDLINE, EMBASE, PsycINFO, Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL Complete and EBSCOhost were searched to identify relevant randomized controlled trials.
