Objective:

to identify preventive interventions for suicidal behavior in adolescent students and young people different from the Guardians model.

Methodology:

systematic review with search in 11 databases, on preventive interventions for suicidal ideation and attempt in educational settings. An evaluation of the methodological quality of the articles and assessment of biases were carried out, through the Cochrane rct risk of bias tool RoB1 for clinical trials, trend for quasi-experiments and Ciapponi for observational ones; qualitative synthesis was performed.

Results:

26 articles out of 31,636 were included, all interventions were educational of three types: face-to-face, virtual and those that combined the two modalities. These were aimed at increasing knowledge and improving attitudes about suicide and facilitating help-seeking; They combined theoretical and practical education, and direct intervention for high-risk subjects. All carried out at school or university. Regarding the assessment of biases, only one study had low quality. All studies reported positive results in increased knowledge about suicide, improved attitudes towards suicidal peers, reduced suicidal ideation and attempt, increased help-seeking, and use of support services available in the setting educational.

Conclusion:

there is a variety of interventions to prevent suicidal behavior, some based on theoretical models, others not. It is necessary to deepen the study of these programs to guide their implementation in other contexts and decision-making in Public Health.
