The purpose of this study was to evaluate the suicide ideation effects of suicide prevention program.
Using several databases, studies were collected from March, 2012 to August, 2012. For the purpose of a systematic literature review, in this study analysis was done of pretested-posttested research among non-randomized studies utilizing suicide prevention program, and having set the intervention as the independent variable suicidal idea as a dependent variable.
The result of interventions on suicide prevention showed a moderate effect at -0.72 (96% CI: -0.96, 0.48). For intervention types, reality therapy was most effective overall, while the life cycle was found to be most effective for young people (d=-1.57, 95% CI: -2.70, -0.43). The periods for the intervention on suicide prevention was shown to be most effective when it was repeated over 20 times (d=-1.55, 95% CI:-2.75, -0.35), and also it worked better for the risk group than a general group (d=-0.89, 95% CI: -1.26, 0.52).
The findings of this study support basic data for interventions to prevent future suicide and the need for further development of prevention programs.
