Treatment of alcohol-related violence: Integrating evidence from general violence and IPV treatment research

Integrated Motivational Strategies for Intimate Partner Violence Perpetrators with Substance Use: A Randomized Controlled Trial

Objective: Intimate partner violence (IPV) perpetrators with alcohol and/or other drug use problems (ADUPs) have been identified as one of the main high-risk and highly resistant groups of perpetrators requiring special attention in intervention programs for IPV perpetrators. This randomized controlled trial (RCT) aimed to evaluate whether an individualized motivational plan adjusted to ADUPs (IMP-ADUPs) was superior to standard motivational strategies (IMP) in reducing ADUPs, and IPV and increasing treatment adherence in IPV perpetrators. Method: Data from a full sample of IPV perpetrators (n = 140) and a subsample of participants with ADUPs (n = 55) were collected at pre- and post-intervention and 12-month follow-up. Final outcomes included alcohol, cocaine, and cannabis use, self-reported IPV, risk of recidivism assessed by facilitators, and official IPV recidivism. Proximal outcomes included treatment adherence (stage of change, intervention dose, active participation, and dropout). Results: Both intent-to-treat (ITT) and per-protocol (PP) analyses were conducted. The IMP-ADUPs condition was superior to the IMP in reducing alcohol use at post-intervention in both the full sample and ADUPs subsample. The full sample of participants in the IMP-ADUPs condition were in a more advanced stage of change post-intervention and showed increased active participation during the intervention process than IMP participants. All participants were in a more advanced stage of change at post-intervention and reduced their alcohol use and their risk of recidivism at post-intervention and 12-month follow-up. Conclusions: These results underscore the need to develop individualized treatment approaches to address participants' risks and needs and promote their motivation to change.

Participants in Court-mandated Intervention Programs for Intimate Partner Violence Perpetrators with Substance Use Problems: A Systematic Review of Specific Risk Factors

Men with alcohol and/or other drug use problems (ADUPs) court-mandated to attend intervention programs for intimate partner violence (IPV) perpetrators have been identified as a high-risk, highly resistant group of IPV perpetrators, as they present lower treatment adherence and higher dropout and recidivism rates. Previous research suggests that IPV perpetrators with ADUPs may require tailored interventions to address their specific risk factors. The present systematic review was conducted using PRISMA guidelines to identify the specific risk factors in men with and without ADUPs on entry to court-mandated perpetrator programs. The following databases were searched from inception to November 2021: Web of Science, PsycINFO, and Scopus. There was a screening of 3,995 records, and 29 quantitative studies were included in the review. Risk factors present in males court-mandated to perpetrator programs were grouped into four categories: sociodemographic risk factors, personality disorders and psychological adjustment, social-relational risk factors, and risk factors related to attitudes towards women. Results indicated that the main risk factors in IPV perpetrators with ADUPs, compared to those without, were higher clinical symptomatology (e.g., anger and impulsivity), personality disorders, poorer executive functions, having experienced more stressful life events, higher exposure to childhood trauma, lower intimate social support, and higher responsibility attributed to the offenders' personal context. These results contribute to a deeper understanding of the complex phenomenon of IPV and ADUPs, and could help to inform key targets for perpetrator programs that may improve the well-being of their (ex)partners and increase the effectiveness of intervention programs for IPV perpetrators.

Programme responses for men who perpetrate intimate partner violence in the context of alcohol or other drugs: a scoping review

Purpose

Substance use plays a significant role in the perpetration of much intimate partner violence (IPV). However, responses to these two issues are rarely integrated. Single focus programme responses can lead to poor outcomes for men as well as their families experiencing these intersecting issues. This scoping paper aims to establish the current state of knowledge on contextual factors influencing the development and implementation of combined programmes.

Design/methodology/approach

Four electronic databases were systematically searched in May 2021 and December 2021. Twenty-one peer-reviewed studies reporting on ten programmes were included.

Findings

This scoping review revealed that combined programme responses are an underdeveloped area of research and evaluation. The limited evidence base indicated systemic barriers hindering services’ capacity to expand this field of work, affecting implementation and outcomes. Support is required from the wider service systems to intervene in men’s perpetration of IPV in the context of substance use.

Practical implications

Findings in this scoping review demonstrate the importance of fostering a coordinated and collective response to IPV in the context of substance use. Combined programmes have the potential to reduce siloed practices, enabling more holistic responses for men with intersecting issues. However, researchers and policymakers must also address contextual issues hindering or enabling combined programmes’ implementation and development.

Originality/value

Mapping the evidence based on combined programmes provides direction for further development and research to expand this field of inquiry.

Interventions to Reduce Intimate Partner Violence Perpetration by Men Who Use Substances: A Systematic Review and Meta-Analysis of Efficacy

INTRODUCTION

Despite the high prevalence of intimate partner violence (IPV) perpetration by men who use substances, limited evidence exists about how best to reduce IPV among this group.

METHOD

A systematic narrative review with meta-analysis determined the effectiveness of interventions to reduce IPV by men who use substances. Inclusion criteria were randomized and nonrandomized controlled trials; adult heterosexual male IPV perpetrators where at least 60% of participants were alcohol and/or drug users; the intervention targeted IPV with or without targeting substance use (SU); outcomes included perpetrator and/or victim reports of IPV, SU, or both. Methodological quality was assessed.

RESULTS

Nine trials (n = 1,014 men) were identified. Interventions were grouped into (1) integrated IPV and SU interventions (n = 5), (2) IPV interventions with adjunct SU interventions (n = 2), and (3) stand-alone IPV interventions (n = 2). Cognitive behavioral and motivational interviewing therapies were the most common approaches. Data from individual trials showed a reduction in SU outcomes in the short term (≤3months; n = 2 trials) and IPV perpetration at different time points (n = 3 trials) for interventions compared with treatment as usual (TAU). Meta-analysis with integrated IPV and SU interventions showed no difference in SU (n = 3 trials) or IPV outcomes (n = 4 trials) versus SU TAU.

CONCLUSIONS

Little evidence exists for effective interventions for male IPV perpetrators who use substances. Outcomes in integrated interventions were not superior to TAU in meta-analysis. Future trials should consider the nature of the relationship between IPV and SU in intervention design, duration of intervention, and type and timing of outcome measures. .

A Qualitative Study of Intimate Partner Violence From the Perpetrator's Perspective

Cognitive-behavioral treatment (CBT) has shown promising results in reducing aggression in intimate partner violence (IPV) relationships. A cornerstone of effective CBT is the assessment and measure of cognitions, behaviors, interactions, and conditions surrounding the violence. Unfortunately, there is limited perpetrator-based research that focuses on these aspects of IPV. The purpose of this study was to question perpetrators about the behaviors, interactions, cognitions, and conditions that precipitate and maintain abuse. Such information, along with similar data collected in a companion study of victims, is intended to assist in better understanding perpetrator violence, which can serve as the foundation of effective cognitive-behavioral (CB) IPV assessment, measurement, and treatment. Twelve heterosexual perpetrators receiving treatment for IPV completed structured audiotaped interviews focusing on CB phenomena, that is, the cognitions, behaviors, feelings, interactions, and conditions perpetrators have before, during, and after an IPV incident. Transcripts were coded and analyzed to develop a broad categorized list of discrete IPV phenomena over time. Among the findings relating to violent incidents was indication that despite the progression of abuse that compels perpetrators uncontrollably toward a violent episode, both partners simultaneously engage in numerous preventive attempts. The findings are ultimately intended to contribute to an instrument or treatment assessment method that can more accurately measure IPV phenomena emphasizing core CB concepts.
