Knowledge Gains Following a Child Sexual Abuse Prevention Program Among Urban Students: A Cluster-Randomized Evaluation. American journal of public health, 105(7), 1344-50.https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4463397/http://hdl.handle.net/11212/3999. We evaluated a school-based child sexual abuse (CSA) prevention program, Safe Touches, in a low–socioeconomic status, racially diverse sample. . Participants were 492 second- and third-grade students at 6 public elementary schools in New York City. The study period spanned fall 2012 through summer 2014. We cluster-randomized classrooms to the Safe Touches intervention or control groups and assessed outcomes with the Children’s Knowledge of Abuse Questionnaire. Hierarchical models tested change in children’s knowledge of inappropriate and appropriate touch. The intervention group showed significantly greater improvement than the control group on knowledge of inappropriate touch. Children in second grade and children in schools with a greater proportion of students in general (vs special) education showed greater gains than other participants in knowledge of inappropriate touch. We observed no significant change in knowledge of appropriate touch among control or intervention groups. Young children benefited from a school-based, 1-time CSA prevention program. Future research should explore the efficacy of CSA prevention programs with children before the second grade to determine optimal age for participation.en-USchild sexual abuseprevention programsevaluation researchArticle
