Methods: The study design was a quasi-randomized control trial: half of the 10th grade classrooms were randomized to receive the five-session DV prevention program (active condition), and half were randomized to receive their usual health class curriculum (control condition). 580 10th grade students in 24 health class sections at a large public high school in New England were eligible to participate in the study, with 420 students providing data for the final sample (231 active, 169 control). Surveys were administered to all students at baseline, the end of the program, and three months after the end of the program. These surveys assessed demographics, DV attitudes and knowledge, DV victimization and perpetration, and health risk behaviors. Following completion of the research study, the control group received the DV prevention program.
Results: Students who received the DV prevention program reported significant changes in terms of knowledge, attitudes and behavior in comparison with students in the control group. Students who received the DV prevention program had higher scores on the relationship violence knowledge scale 3 months after completing the program. Active group students also reported less approval of aggression after three months on measures of general and retaliatory aggression. Regarding DV attitudes, prevention program students reported less acceptance of both male and female violence perpetration than did control students after three months. Finally, a decline in average DV perpetration in the active condition between baseline and the three-month follow-up was significant at the trend level, whereas the control group mean for perpetration went up during this period.
Conclusions: These findings suggest that a community-based DV prevention can promote change in attitudes and knowledge among high school students. The trend-level difference in DV perpetration is especially promising because behavior change is difficult to detect with brief, universal interventions.
