To determine whether an interactive curriculum that integrates dating violence prevention with lessons on healthy relationships, sexual health, and substance use reduces physical dating violence (PDV).Design: Cluster randomized trial with 2.5-year followup; prespecified subgroup analyses by sex.Setting: Grade 9 health classes.Participants: A total of 1722 students aged 14-15 from 20 public schools (52.8% girls).Intervention: A 21-lesson curriculum delivered during 28 hours by teachers with additional training in the dynamics of dating violence and healthy relationships. Dating violence prevention was integrated with core lessons about healthy relationships, sexual health, and substance use prevention using interactive exercises. Relationship skills to promote safer decision making with peers and dating partners were emphasized. Control schools targeted similar objectives without training or materials. Main Outcome Measures:The primary outcome at 2.5 years was self-reported PDV during the previous year. Secondary outcomes were physical peer violence, sub-stance use, and condom use. Analysis was by intentionto-treat. Results:The PDV was greater in control vs intervention students (9.8% vs 7.4%; adjusted odds ratio, 2.42; 95% confidence interval, 1.00-6.02; P = .05). A significant group ϫ sex interaction effect indicated that the intervention effect was greater in boys (PDV: 7.1% in controls vs 2.7% in intervention students) than in girls (12.1% vs 11.9%). Main effects for secondary outcomes were not statistically significant; however, sex ϫ group analyses showed a significant difference in condom use in sexually active boys who received the intervention (114 of 168; 67.9%) vs controls (65 of 111 [58.6%]) (PϽ.01). The cost of training and materials averaged CA$16 per student. Conclusion:The teaching of youths about healthy relationships as part of their required health curriculum reduced PDV and increased condom use 2.5 years later at a low per-student cost.

A wide range of children's developmental outcomes are compromised by exposure to domestic violence, including social, emotional, behavioral, cognitive, and general health functioning. However, there are relatively few empirical studies with adequate control of confounding variables and a sound theoretical basis. We identified 41 studies that provided relevant and adequate data for inclusion in a meta-analysis. Forty of these studies indicated that children's exposure to domestic violence was related to emotional and behavioral problems, translating to a small overall effect (Zr = .28). Age, sex, and type of outcome were not significant moderators, most likely due to considerable heterogeneity within each of these groups. Co-occurrence of child abuse increased the level of emotional and behavioral problems above and beyond exposure alone, based on 4 available studies. Future research needs are identified, including the need for large-scale longitudinal data and theoretically guided approaches that take into account relevant contextual factors.

Premised on the understanding that domestic violence is a broad concept that encompasses a wide range of behaviors from isolated events to a pattern of emotional, physical, and sexual abuse that controls the victim, this article addresses the need for a differentiated approach to developing parenting plans after separation when domestic violence is alleged. A method of assessing risk by screening for the potency , pattern , and primary perpetrator of the violence is proposed as a foundation for generating hypotheses about the type of and potential for future violence as well as parental functioning. This kind of differential screening for risk in cases where domestic violence is alleged provides preliminary guidance in identifying parenting arrangements that are appropriate for the specific child and family and, if confirmed by a more in-depth assessment, may be the basis for a long-term plan. A series of parenting plans are proposed, with criteria and guidelines for usage depending upon this differential screening, ranging from highly restricted access arrangements (no contact with perpetrators of family violence and supervised access or monitored exchange) to relatively unrestricted ones (parallel parenting) and even co-parenting. Implications for practice are considered within the context of available resources.
