    Input: In response to recent calls for programs that can prevent multiple types of youth violence , the current study examined whether Safe Date s , an evidence -based dating violence prevention program , was effective in preventing other forms of youth violence . Using data from the original Safe Date s r and omized controlled trial , this study examined ( 1 ) the effectiveness of Safe Date s in preventing peer violence victimization and perpetration and school weapon carrying 1 year after the intervention phase was completed and ( 2 ) moderation of program effects by the sex or race/ethnicity of the adolescent . Ninety percent ( n = 1,690 ) of the eighth and ninth grade rs who completed baseline question naires completed the 1-year follow-up assessment . The sample was 51 % female and 26 % minority ( of whom 69 % was black and 31 % was of another minority race/ethnicity ) . There were no baseline treatment group differences in violence outcomes . Treatment condition was significantly associated with peer violence victimization and school weapon carrying at follow-up ; there was 12 % less victimization and 31 % less weapon carrying among those exposed to Safe Date s than those among controls . Treatment condition was significantly associated with perpetration among the minority but not among white adolescents ; there was 23 % less violence perpetration among minority adolescents exposed to Safe Date s than that among controls . The observed effect sizes were comparable with those of other universal school-based youth violence prevention programs . Implementing Safe Date s may be an efficient way of preventing multiple types of youth violence BACKGROUND A large proportion of the female population all over the world , particularly in developing countries , experience some form of gender-based violence ( GBV ) during their life . Early marriage , a form of GBV , is particularly highly prevalent in rural Upper Egypt . OBJECTIVES The aim of the current study was to assess the knowledge , attitudes and practice s ( KAP ) of adolescents in Upper Egypt on domestic GBV , with a focus on early girls ' marriage . PARTICIPANTS AND METHODS The study was a cross-sectional descriptive household survey targeting 400 r and omly selected adolescent boys and girls aged 11 - 16 years from five villages of Minya Governorate in Upper Egypt . RESULTS The proportion of interviewed adolescents who could identify certain practice s as forms of GBV was relatively low : the identified practice s were mainly deprivation of work ( 9.0 % ) , deprivation of inheritance ( 3.3 % ) , arbitrary neglect and desertion ( 2.8 % ) , and preventing from visiting relatives ( 0.5 % ) . Abusive sexual behavior was not identified by any of the study participants as a form of domestic GBV . A total of 112 boys ( 56.0 % ) reported that they have been perpetrators in domestic GBV events at least once and 118 girls ( 59.0 % ) reported that they have been actual victims of domestic GBV . An overall 65.6 % of study participants could correctly identify the legal age of marriage as 18 years , yet only 22.0 % identified earlier ages of marriage as a form of domestic GBV . The vast majority of girls and boys reported that they would not agree to get married before the age of 18 years ( 91.0 and 87.0 % , respectively ) . CONCLUSION AND RECOMMENDATIONS Adolescents in Upper Egypt demonstrated a less than satisfactory knowledge about the forms of GBV . Although early girls ' marriage was not universally recognized by adolescents as a form of domestic GBV , they demonstrated satisfactory knowledge about the legal age of marriage , as well as a tendency to ab and on the practice . Establishing a community-based awareness program for adolescents of both sexes about GBV with a focus on early girls ' marriage is highly recommended
