Background
Domestic violence mechanisms are frequently transmitted across generations, representing a global issue demanding particular attention. This study investigates the intergenerational transmission of intimate partner violence (IPV) and parent-to-child violence (PCV) and whether participating in a multilevel preventive intervention (Fast Track) breaks this transmission.
Methods
In high-risk elementary schools located in the United States, children considered at high risk for aggressive behavior based on teachers’ and parents’ screen scores were assigned to either a 10-year intervention or a control group based on their school. The Fast Track trial was registered at clinicaltrials.gov (NCT01653535) and was focused on parenting practices and children’s intrapersonal, interpersonal, and academic skills. From the original 891 children, 374 participants with children aged less than 18 years (n = 191 intervention group, n = 183 control group) reported at age 34 their experience with domestic violence and their children’s psychological adjustment.
Results
The intergenerational mediating pathway from high IPV in the first generation to high PCV in the second generation to greater total mental health difficulties in the third generation was statistically significant in the control group but not in the intervention group.
Conclusions
IPV was intergenerationally transmitted by influencing PCV, with a negative effect on the third generation’s mental health. Nevertheless, participation in the Fast Track intervention disrupted this cycle. These findings suggest the importance of policies to support preventive childhood interventions.
