Occupational therapy delivered by specialists versus non‐specialists for people with schizophrenia.

Schizophrenia is a severe mental health condition that is characterised by positive symptoms, such as hallucinations and delusions; negative symptoms, such as flattened affect, thought disorder (disrupted speech), and lack of motivation; and cognitive symptoms, such as problems with memory and attention.

However, similar interventions may also be delivered by staff not trained as occupational therapists. Objectives To examine the effects of occupational therapy delivered by occupational therapists compared to occupational therapy delivered by any other person for people with schizophrenia. Search methods We searched the Cochrane Schizophrenia Group's Study‐Based Register of Trials (including trial registers) on 4 November 2016 and 26 July 2018. Selection criteria All randomised controlled trials evaluating the functional or clinical outcomes of occupational therapy, or both, for people with schizophrenia delivered by occupational therapists compared with occupational therapy for people with schizophrenia delivered by anyone other than occupational therapists.
