Objective: Positive psychology interventions (PPIs) incorporate principles of personal strengths with the view that mental health recovery transcends symptom relief. Severe psychiatric conditions, such as schizophrenia, may benefit from such interventions. This study aims to gather the current evidence on the impact of PPIs on increasing well-being in patients on the schizophrenia spectrum and assess reductions in negative or positive symptoms. Methods: A systematic review of PPI studies with schizophrenia-spectrum patients was carried out following PRISMA recommendations. The PubMed, PsycINFO, Web of Science, and Scopus databases were searched for relevant publications in order to understand the possible effects of these interventions on well-being measures and psychotic symptoms in this population. Results: Nine studies (four controlled) were included. Meta-analysis of the controlled studies showed a significant effect (p = 0.04) for improvement of well-being (Z = 2.01). Overall, the reviewed evidence suggests well-being improvement. The effect on reduction of negative symptoms was unclear. Conclusion: Used as an adjunctive therapy, PPIs appear to be a promising resource for patients on the schizophrenia spectrum, with possible effects on well-being and symptom reduction.
