School-based Child Sexual Abuse Interventions: A Systematic Review and Meta-analysis

Abstract

Purpose The purposes of this systematic review were to systematically summarize components in existing school-based child sexual abuse (CSA) prevention programs and identify predictors for program effectiveness. Method Building upon the most comprehensive systematic review on this topic, we conducted systematic searches in both English-language from September 2014 to October 2020 and Chinese-language from inception to October, 2020. Meta-regressions were performed to identify predictors for program effectiveness. Results Thirty-one studies were included with a total sample size of 9049 participants. Results from meta-analyses suggested that interventions are effective in increasing participants’ CSA knowledge as assessed via questionnaires ( g = 0.72, 95% CI [0.52–0.93]) and vignette-based measures ( g = 0.55, 95% CI [0.35–0.74]). Results from meta-regression suggested that interventions with more than three sessions are more effective than interventions with fewer sessions. Interventions appear to be more effective with children who are 8 years and older than younger children. Discussion CSA is a global issue that has significant negative effects on victims’ physical, psychological, and sexual well-being. Our findings also provide recommendations for future research, particularly in terms of optimizing the effectiveness of school-based CSA prevention programs, and the better reporting of intervention components as well as participant characteristics.

The cost-effectiveness of school-based interventions for chronic diseases: a systematic review

“…There has been substantial literature and reviews on the efficacy of mental health intervention programs in school-setting. The interventions have targeted a number of different mental health disorders such as depression and anxiety [ 45 – 47 ], developmental disorders [ 48 , 49 ], bullying [ 50 ] and abuse [ 51 ], as well as other social/behavioral problems and mediators of poor mental health. Systematic reviews have generally found favorable outcome for school-based intervention, which evidenced small-to-moderate impact of universal interventions on positive mental well-being, mental health disorders, violence and bullying, and pro-social behavior, as well as learning, and behavior and attitudes towards school (i.e., achievement in test scores and school grades, commitment to school, and school attendance) [ 52 ].…”

Enhancing Child Sexual Abuse Prevention Knowledge With an Educational Toolkit -Evaluation of the Chinese Doll Program

“…Shifts social values have led to increased awareness of "child abuse," with the Chinese term "Nue Tong" being used to define child victimization [7]. Although several studies have shown the benefits of formal, systematic, and repeated training through school-based CSA prevention programs [9][10][11][12][13][14][15][16][17], these school-based CSA prevention programs, which incorporate educational materials such as courses and dramatic performances may not be fully applicable in China because of the lack of systematic education faculty [18], and their preparation and implementation may be impractical due to time and resource constraints in schools [19,20]. Particularly during the COVID-19 pandemic, school-based interventions became unfeasible, emphasizing the importance of remote digital interventions as promising solutions for addressing resource limitations and expanding reach [21][22][23].…”

Knowledge of Children Related to Reproductive Health to Prevent Child Sexual Abuse in Elementary Schools

“…The CKAQ-RIII questionnaire will be used in Greek elementary schools in order to evaluate the efficacy of prevention programs as well as students' levels of knowledge regarding the prevention of sexual harassment [13]. Concur with Meng Yao, who stated in [14], that providing interventions does effectively increase knowledge of sexual violence in children.…”
