Abstract: Introduction: Early‐onset psychotic disorders include the prodromal phase and the first‐episode psychosis (FEP). They constitute a high‐risk period for suicidal behavior. Early intervention for psychosis (EIP) consists of intervening as early as possible. The effectiveness of early intervention on overall prognosis has been reported in numerous studies, and EIP services are emerging worldwide. Several authors report an improvement in suicidal behavior, but no study has looked at all the data. Aims of the Study: The aim of work is to study whether early intervention for psychosis has an impact on deaths by suicide and suicide attempts, and study which intervention methods have an impact on suicidal behavior. Methodology: By respecting the PRISMA criteria, previously declared on PROSPERO, by exploring 5 medical databases (PubMed, Cochrane, PsycINFO, Scopus, Embase), from their creation dates, published until 20/02/2023, in English, we carried out a meta‐analysis. The articles selected had to deal with the EIP and deaths by suicide or suicide attempts. Our primary outcome is the deaths by suicide and the secondary outcome the suicide attempt. Results: The exhaustive search identified a total of 2310 references. Nine articles were included. Their intervention modalities were pharmacotherapy, psychotherapy, case‐management, or related services, and psycho‐social therapies. Our meta‐analysis shows that early intervention for early‐onset psychotic disorders is associated with a statistically significant reduction by a third in deaths by suicide (ORa = 0.66 (0.49–0.88), p = 0.005) and by a third in suicide attempts (ORa = 0.66 (0.50–0.86), p = 0.002), with non‐significant heterogeneity. Sensitivity analyses excluding the study with statistical difficulties due to the absence of an event and studies with a high risk of bias point in the same direction, that is a statistically significant reduction and non‐significant heterogeneity. Conclusion: The literature shows that early intervention programs are associated with positive impact on deaths by suicide and suicide attempt. This is the first meta‐analysis of early intervention in early psychotic disorders and its impact on suicidal risk. The deployment of EIP should be supported worldwide in order to intervene as early as possible and prevent the risk of suicide. Trial Registration: PROSPERO CRD42022366976 [ABSTRACT FROM AUTHOR]
