Interpersonal violence intervention is an issue of immediate and critical concern. Throughout this handbook various forms of interpersonal violence across the lifespan are discussed and evaluated, with current strategies and interventions. The field of intervention regarding various forms of abuse involving children and older adults, sexual assault, and domestic violence has already made significant advances. To date, increasing attention, both public and professional, has been given to these areas of victimization, in terms of assessment tools, and treatment approaches using evidence-based and trauma-informed strategies, but much more can be done to eliminate this epidemic of violence in our society. In addition to the immediate impact of physical harm, interpersonal violence results in longterm psychological damage to not only the individual victim but to families and society at large. Therefore, it is incumbent on those working in the field to conduct assessments of treatment programs and evaluate current research to create more effective treatment protocols along with evidence-based implementations. This chapter focuses on future interventions covering both victims and perpetrators, as well as systemic issues that are central to research, practice, policy, and advocacy. In order to be effective, interventions and research must be equipped to meet the formidable challenges posed by the complexity, persistence, and traumatic effects of interpersonal violence as a social, cultural, and intergenerational problem affecting diverse populations and communities.
