Abstract
(1) Background: Suicide is a worldwide leading cause of death among people with mental disorders. Psychoeducation is an integral component of mental health care that may offer patients valuable tools to understand their conditions, develop coping strategies, and engage more effectively in the treatment process. In the present scoping review, we aimed to summarize the evidence on the implementation of psychoeducational interventions in inpatient settings after suicide attempts. (2) Methods: In August 2024, we searched the Web of Knowledge (all databases), PsycINFO, and CINAHL databases following the PRISMA-ScR guidelines. We included original articles evaluating the effects of psychoeducational interventions for patients hospitalized in psychiatric settings after a suicide attempt. We provided a narrative synthesis of the study characteristics and the main findings of the included studies. (3) Results: We included five papers reporting the results of six studies, of which two were randomized controlled trials. Participants were diagnosed with diverse mental disorders, and interventions were generally short in the hospitalization phase, with follow-ups in the short or long term. Outcomes were focused on suicidal ideation, depressive symptoms, and general functioning, along with feasibility and acceptability of the intervention. Psychoeducational interventions were generally well accepted, but more evidence is needed to determine their efficacy. (4) Conclusions: Psychoeducational intervention in an inpatient psychiatric setting may be important for the prevention of future suicide attempts. Nevertheless, research on the topic is still scarce. Methodologically sound randomized controlled trials evaluating the long-term efficacy of psychoeducational interventions on suicide prevention are needed. Future research should also investigate the utility of psychoeducation in non-psychiatric inpatient settings.
