Systematic Investigation of Meta-Analysis Data on Treatment Effectiveness for Physical, Psychological, and Sexual Intimate Partner Violence Perpetration

Abstract

Intimate partner violence can lead to physical, economical, mental, and sexual well-being issues, and even death, and it is most commonly experienced by women. There exist a number of treatment models for the prevention and treatment of intimate partner violence (IPV). In this study, we provided a comprehensive meta-regression analysis of the effectiveness of batterer treatment programs, with a view to characterizing the interplay between different forms of IPV (physical, psychological, and sexual). Using meta-regression, we explore the effect sizes and whether IPV treatment methods have distinct impacts on the outcomes. We use the difference normalized by pretreatment mean and variance foldchange to uncover the relationship between different violence subtypes and how they drive each other. Specifically, our study found that studies with more pre-treatment psychological and/or sexual violence, lead to less favorable outcomes while the studies that start with more physical violence are able to demonstrate their effects more effectively. Results of this study can be used to help the clinician effectively select the treatment for the perpetrator based on the violence type and severity of violence in order to more effectively treat the needs for each specific relationship.

Treatment Resistant Perpetrators of Intimate Partner Violence: Research Advances

“…In this special issue we aim to better understand the therapeutic needs, risk factors, and treatment resistance in IPV perpetrators to provide evidence-based responses to improve intervention programs. In the first manuscript of the special issue, Systematic investigation of meta-analysis data on treatment effectiveness for physical, psychological and sexual intimate partner violence perpetration, Ouztüzün et al (2023) found that differences in the effectiveness of perpetrator programs that may exist depending on the type of violence they are working with. Using meta-regression analysis, these authors assess the effects that different treatment models have on physical, psychological and sexual IPV.…”
