School

To assess evidence of the effectiveness of school-based education programs for the prevention of child sexual abuse (CSA). The programs deliver information about CSA and strategies to help children avoid it and encourage help seeking. Systematic review including meta-analysis of randomized controlled trials (RCTs), cluster RCTs, and quasi-RCTs. Twenty-four studies with 5,802 participants were included. Child self-protective skills, odds ratio = 5.71, confidence interval = [1.98, 16.51]; factual, standardized mean difference (SMD) = 0.61 [0.45, 0.78]; and applied knowledge, SMD = 0.45 [0.24, 0.65], increased in the intervention group, and knowledge gains were retained at 6 months, SMD = 0.69 [0.51, 0.87]. There were no differences in anxiety or fear, SMD = ？0.08 [0.22, 0.07], and findings regarding disclosure of abuse were inconclusive. Children’s self-protective skills and knowledge can be increased by participation in school-based sexual abuse prevention programs. However, it is unknown whether gains in skills and knowledge actually decrease the likelihood of CSA
