Objective: This article aimed to review and meta-analyse the relationship between social problem-solving and suicidal ideation, behavior, and risk (a combined measure of ideation and behavior). Method: A systematic search was carried out in February 2023 using PsycINFO, MEDLINE, Web of Science, and PubMed. Key inclusion criteria were published studies that recruited adults (aged ≥16 years), clinical or nonclinical samples, and presented data on the relationship between social problem-solving and suicidal ideation, behavior, or risk. Findings were meta-analysed and narratively reviewed. Results: A total of 35 studies were included in the review. Meta-analyses showed small-medium-sized negative relationships between social problem-solving and suicidal ideation (r = −.28) and suicide risk (r = −.24). A narrative synthesis also suggested a relationship between social problem-solving and suicidal behavior. These relationships appeared to be partly explained by depression and/or hopelessness. The relationships between social problem-solving facets and suicidal ideation, behavior, and risk, varied. Discussion: These findings provide the most robust evidence to date for the role of social problem-solving in suicidality and have important implications for risk assessment and intervention development. The generalizability of the findings is limited due to study samples being biased toward young, female, university students from the United States.
Public Health Significance StatementThis review of 35 studies found that people who perceived themselves to be better at solving everyday problems also experienced fewer suicidal thoughts and were less likely to attempt suicide. These findings provide stronger evidence than was previously available for the role of social problem-solving in suicidality. However, as these findings were correlational, future research is needed to explore whether changes in social problem-solving (e.g., through interventions) lead to changes in suicidality.
