A Telephone Intervention for Substance-Using Adult Male Perpetrators of Intimate Partner Violence

The Effectiveness of Intervention Programs for Perpetrators of Intimate Partner Violence with Substance Abuse and/or Mental Disorders: A Systematic Review

Despite the high prevalence and severity of intimate partner violence (IPV) perpetration among men with mental health (MH) problems and substance use (SU), there is limited evidence on the most effective ways to reduce IPV within these groups. Hence, the present systematic review aims to evaluate the effectiveness of psychological interventions for male IPV perpetrators with MH issues and SU problems. Five databases (B-On, Pubmed PsycInfo, Science Direct, and Scopus) were searched for studies examining the effectiveness of IPV interventions. Twenty-three studies met the inclusion criteria, with 13 interventions described. Interventions were grouped into (1) specific interventions for SU among IPV perpetrators (k = 8), (2) nonspecific interventions for SU among IPV perpetrators (K = 3), and (3) specific interventions targeting MH among IPV perpetrators (k = 2). Cognitive behavioral therapy and motivational interviewing techniques were the most common approaches. Both specific and nonspecific programs addressing SU problems showed some positive effects on perpetrators' behavior and attitudes. However, data from the two intervention programs focusing on MH showed reduced symptoms and re-assaults but without significant differences between the conditions. Despite methodological shortcomings in the studies, the specific and nonspecific interventions targeting SU and IPV show promise, which hinders drawing firmer conclusions. Nonetheless, further research is necessary to deepen our understanding of the MH impact interventions on IPV perpetrators.

Histories of violence among clients seeking substance use disorder treatment: a systematic mapping review

Introduction

There is a limited literature base regarding the intersection of drug and alcohol treatment, violence, and trauma. While research substantiates that exposure to violence and trauma impacts the propensity to misuse substances, the conceptualization in clinical trials and practice has largely been narrow and gendered, referring only to intimate partner or domestic violence. Our systematic mapping review explored a more inclusive and expansive review of survivors of and perpetrators of violence and trauma (e.g., intimate partner violence, sexual assault, stalking, child abuse, political and community violence, criminal violence, micro violence, structural violence, and oppression) to establish: 1) the types of treatment settings included in intervention studies, 2) the common indicators of success or common outcomes recorded, and 3) understanding who is seeking treatment for drug and alcohol use with histories of violence.

Methods

A systematic mapping review was conducted to identify any peer-reviewed articles published from 2011 to 2022. The Web of Science database was searched using a broad set of Boolean search terms related to violence, substance use disorders, and treatment. Over 8,800 records were identified from the systematic review with a total of 48 articles meeting inclusion criteria.

Results

Most studies in this review included populations reporting perpetration of violence (n=23, 48%) versus participants reporting survival of trauma/violence (n=17, 35%). Results also indicated female identifying populations (n=19; 40%) were predominantly served, were treated in the US (n=33; 69%) and seen in an outpatient setting (n=24; 50%). Authors also were attentive to studies that included sexual and gender minorities and discovered only three studies (6%) explicitly acknowledging inclusion of transgender participants or participants in relationship with partners of the same sex; three more studies (6%) were focused on participants with histories of or engaging in sex work.

Discussion

This review outlines treatment and research implications directly situated in the gap of service delivery found in this review. Specifically, the results elucidate the impact on minoritized and excluded identities based on gender, sexual preference, criminal legal status and directions for research and treatment to increase inclusion, representation, and equity across research and treatment settings.

Characterizing Disparities in the Treatment of Intimate Partner Violence

Exposure to Intimate Partner Violence (IPV) has lasting adverse effects on the physical, behavioral, cognitive, and emotional health of survivors. To this end, it is critical to understand the effectiveness of IPV treatment strategies in reducing IPV and its debilitating effects. Meta-analyses designed to comprehensively describe the effectiveness of treatments offer unique advantages. However, the heterogeneity within and between studies poses challenges in interpreting findings. Meta-analyses are therefore unlikely to identify the factors that underlie disparities in treatment efficacy. To characterize the effect of demographic and social factors on treatment effectiveness, we develop a comprehensive computational and statistical framework that uses Meta-regression to characterize the effect of demographic and social variables on treatment outcomes. The innovations in our methodology include (i) standardization of outcome variables to enable meaningful comparisons among studies, and (ii) two parallel meta-regression pipelines to reliably handle missing data.

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.

Perspectives on Motivation and Change in an Intervention for Men Who Use Substances and Perpetrate Intimate Partner Abuse: Findings From a Qualitative Evaluation of the Advance Intervention

Despite consistent evidence that substance use is a contributory risk factor for perpetration of intimate partner abuse (IPA), little evidence exists for effective interventions for male IPA perpetrators who use substances. The Advance intervention aimed to meet this need. This 16-week intervention addressed both IPA and substance use, and was for men accessing substance use treatment who had perpetrated IPA toward a female (ex-)partner within the last 12 months. Two key theories underpinned the intervention: goal theory and self-regulation theory. In this article, we aim to illustrate the views of men and substance use treatment staff on men's motivations to change, the ways in which men and staff said that men had changed their behavior, and the aspects of the intervention that they reported were key in the process of change. Using framework analysis, we analyzed data from 12 men who took part in the intervention as well as 31 staff members from substance use treatment services. Our five overarching themes were personal goal setting and motivation; recognition of IPA and the substance using lifestyle; improved self-regulation; considering the impact on others; and learning together in a group. Men and staff valued having a program that integrated IPA and substance use and thought the program was unique and much needed. Moreover, our findings suggest that goal theory, self-regulation, and more broadly, motivational and strengths-based approaches with practice-based activities, may be beneficial for effecting change in the substance using perpetrator population. However, further research is needed to determine the effectiveness of the intervention. Overall, our findings highlight the value of using qualitative outcome measures of perpetrator programs to complement quantitative measures of impact.

Barriers and facilitators of implementing integrated interventions for alcohol misuse and intimate partner violence: A qualitative examination with diverse experts

INTRODUCTION

Alcohol misuse and intimate partner violence (IPV) are major public health burdens with a well-established association. These problems are difficult to remedy individually and can exacerbate one another, compounding treatment complexity. Though scarce, integrated alcohol misuse and IPV treatments exist. Yet implementation remains inadequate. Thus, the current study applied the Consolidated Framework for Implementation Research (CFIR) to examine barriers and facilitators of implementing such integrated treatments.

METHODS

Through purposive sampling, we conducted in-depth interviews with diverse IPV and alcohol treatment experts (n = 21) whose ages ranged from 27 to 72 and who averaged 17 years of experience working in alcohol and IPV treatment. The research team conducted analysis using Grounded Theory Methods.

RESULTS

Experts identified barriers and facilitators for integrated treatment of alcohol misuse and IPV in three CFIR domains: intervention, inner setting and provider, and outer setting.

CONCLUSIONS

Leveraging the facilitators of implementation and addressing barriers at multiple organizational and intervention levels through an implementation science lens can help to close the research-to-practice gap for integratively treating alcohol misuse and IPV.

What's In It for Me? Motivating the Untreated Abuser to Consider Treatment

This paper presents findings of a second trial evaluating telephone-based motivational enhancement therapy (MET) to motivate untreated and unadjudicated men who abuse their intimate partners to explore treatment options. Participants' perceptions of how their abuse is negatively affecting them personally are a highlight of the paper. One hundred forty-one adult men were recruited through social marketing and randomly assigned to the intervention (MET) or comparison (Mail) group. The MET condition consisted of two feedback sessions guided by a personalized feedback report on participants' intimate partner violence (IPV) and substance use. The Mail condition included a mailed educational brochure on IPV and substance use. Results supported the likely effectiveness of MET in short-term reduction of IPV behavior, marijuana use, and increasing motivation for treatment seeking particularly for participants who reported more adverse consequences of IPV to themselves. Findings emphasize the importance of including a focus in interventions on IPV's impact on the abusers themselves. The study's virtual participation and success in reaching and retaining a diverse population of male abusers can contribute to transformative justice and communities looking for alternative early interventions for men of color prior to encountering the criminal justice system.

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. .

Pathways to Seeking Help From a Partner Abuse Intervention Program: A Qualitative Study of Voluntary and Non-Court-Mandated Latino Men's Experiences

Involvement in treatment for intimate partner violence and abuse (IPV/A) perpetration is often limited to those who are arrested and convicted of domestic violence offenses. Consequently, the majority of research into partner abuse intervention programs (PAIPs; also known as batterer intervention programs [BIPs]) has utilized data from court-mandated participants despite the existence of voluntary programs. Therefore, little is known about the experiences of voluntary and non-court-mandated BIP/PAIP participants. Using an interpretive phenomenological analysis, this study sought to understand how participants perceived their lived experience in seeking help from a voluntary BIP/PAIP serving Latino men. Men volunteering for this study participated in semi-structured in-depth interviews (N = 16). The findings reveal that the decision to engage in a BIP/PAIP voluntarily is process laden. Participants described the process as involving a breakdown in the health of their intimate relationship, reaching tipping points at which avoiding help was no longer an option, and locating specific information on where to seek treatment. The findings also reveal that once involved, most participants anticipated and desired to engage in the program long term. This study illuminates the many factors that may contribute to decision-making when men who have acted abusively seek help. Strategies for increasing voluntary BIP/PAIP participation may involve enhancing marketing of services or information for accessing services, and personal relationship building between facilitators and potential participants.

Using the Behaviour Change Wheel to design an intervention for partner abusive men in drug and alcohol treatment

Background

We aimed to establish what core elements were required in a group therapy programme for men who disclose perpetrating intimate partner abuse in a substance use setting and develop, and test the feasibility of delivering an intervention in this setting.

Methods

We describe the theoretical development and feasibility testing of an integrated substance use and intimate partner abuse intervention (‘ADVANCE’) for delivery in substance use services. We employed a comprehensive eight-stage process to guide this development applying the ‘COM-B’ (‘capability’, ‘opportunity’, ‘motivation’ and ‘behaviour’) model for intervention design which specifies the following: (1) define the problem, (2) select the target behaviour, (3) specify the target behaviour, (4) identify what needs to change, (5) identify intervention functions, (6) identify policy categories, (7) select behaviour change techniques, and (8) design a mode of delivery. The development was informed by primary research conducted by the authors, consulting with organisation steering groups and by those with personal experiences. The identified targets for intervention and mode and method of delivery were then refined over 4 intervention development meetings, using the nominal group technique with the ADVANCE experts, then further refined following consultation with service user groups and wider expert groups via a learning alliance meetings.

Results

Our final intervention, the ADVANCE intervention consisted of a group intervention comprising of up to four pre-group individual interviews, followed by 12 × 2-h group sessions supported by integrated safety work for victim/survivors, and risk and safety support and integrity support for the professionals. The main targets for change were personal goal planning, self-regulation, and attitudes and beliefs supporting intimate partner abuse. The intervention was regarded as very acceptable to both staff and clients in substance use services, with group attendees reported positive behaviour changes and development of new skills.

Conclusion

We have demonstrated the ability to employ a structured eight-step process to develop an integrated intervention to address substance use-related intimate partner abuse that is acceptable to staff and clients in substance use services. This led to a feasibility study (ISRCTN 79435190) involving 104 men and 30 staff at three different locations across the UK was conducted to assess the feasibility and acceptability of the intervention and to refine the content and approach to delivery (BMC Public Health, 21: 980, 2021).

ADVANCE integrated group intervention to address both substance use and intimate partner abuse perpetration by men in substance use treatment: a feasibility randomised controlled trial

BACKGROUND

Substance use is a risk factor for intimate partner abuse (IPA) perpetration. Delivering perpetrator interventions concurrently with substance use treatment shows promise.

METHODS

The feasibility of conducting an efficacy and cost-effectiveness trial of the ADVANCE 16-week intervention to reduce IPA by men in substance use treatment was explored. A multicentre, parallel group individually randomised controlled feasibility trial and formative evaluation was conducted. Over three temporal cycles, 104 men who had perpetrated IPA towards a female (ex) partner in the past year were randomly allocated to receive the ADVANCE intervention + substance use treatment as usual (TAU) (n = 54) or TAU only (n = 50) and assessed 16-weeks post-randomisation. Participants' (ex) partners were offered support and 27 provided outcome data. Thirty-one staff and 12 men who attended the intervention participated in focus groups or interviews that were analysed using the framework approach. Pre-specified criteria assessed the feasibility of progression to a definitive trial: 1) ≥ 60% of eligible male participants recruited; 2) intervention acceptable to staff and male participants; 3) ≥ 70% of participants followed-up and 4) levels of substance use and 5) IPA perpetrated by men in the intervention arm did not increase from average baseline level at 16-weeks post-randomisation.

RESULTS

70.7% (104/147) of eligible men were recruited. The formative evaluation confirmed the intervention's acceptability. Therapeutic alliance and session satisfaction were rated highly. The overall median rate of intervention session attendance (of 14 compulsory sessions) was 28.6% (range 14.3-64.3% by the third cycle). 49.0% (51/104) of men and 63.0% (17/27) of their (ex) partners were followed-up 16-weeks post-randomisation. This increased to 100% of men and women by cycle three. At follow-up, neither substance use nor IPA perpetration had worsened for men in the intervention arm.

CONCLUSIONS

It was feasible to deliver the ADVANCE intervention in substance use treatment services, although it proved difficult to collect data from female (ex)partners. While some progression criteria were met, others were not, although improvements were demonstrated by the third cycle. Lessons learned will be implemented into the study design for a definitive trial of the ADVANCE intervention.

Using Reoffenders' Experiences and Perspectives to Improve Intimate Partner Violence Treatment

A substantial proportion of partner-violent men reoffend subsequent to completing intimate partner violence (IPV) treatment. A critical step in enhancing treatment for IPV perpetration is to understand reoffense among those who recidivate following treatment completion. Investigating reoffenders' own perceptions regarding potential directions for treatment modification may improve overall treatment outcomes. Qualitative research examining the experiences of participants who utilize IPV treatment is limited. In the present study, we examined implications for treatment from an exploration of reoffenders' interpretation of their recidivist events and their beliefs regarding treatment effectiveness. A constructivist grounded theory approach was used to generate theory regarding behavior change, treatment perceptions, and recidivist processes among men who experience difficulty staying nonviolent. Emergent qualitative themes revealed reoffenders' perceptions of treatment and suggestions for treatment modification. Reoffenders identified program factors that they believed would have enhanced program effectiveness for themselves, and thus may have prevented their recidivist incidents. Treatment implications that emerged from reoffenders' narratives are organized along three key dimensions: modality-specific variables, which were relevant to treatment approach and effectiveness of group therapy; content-specific variables, which were relevant to skill acquisition and skill application; and participant-specific variables, which were relevant to intrapersonal characteristics of the participants themselves. Recommendations for treatment enhancement are discussed.

Toward a unifying theory of dysregulated behaviors

Dysregulated behaviors, defined as active behaviors that have short-term benefits but cause serious recurrent long-term distress or impairment to the individual and/or those around them, include behaviors such as suicidal and nonsuicidal self-injury, aggression, and substance use. These behaviors are common and costly to the individual, their friends and family, and society. Despite similar etiological models and interventions, dysregulated behaviors have largely been studied in isolation from one another. The goals of this paper were to a) define dysregulated behaviors as a coherent class of behaviors, b) review the prevalence and consequences of dysregulated behaviors, c) outline how dysregulated behaviors fit into current models of psychopathology, and d) describe the key questions to be addressed by future research in this area. It is argued that integrating across theories of discrete dysregulated behaviors can help provide aid in the development of etiological models, which in turn can improve prevention and intervention for dysregulated behaviors.

Discussing substance use with clients during the COVID-19 pandemic: A motivational interviewing approach

During the COVID-19 pandemic, trauma-exposed individuals may have heightened risk for substance use. Using substances to cope may contribute to the development of problematic substance use over time. It is imperative to initiate conversations about substance use with clients during this time and motivational interviewing offers an ideal framework for doing so.

Meta-analysis and systematic review for the treatment of perpetrators of intimate partner violence

Aim of this study is to investigate the effectiveness of different batterer intervention programs in reducing violence for male IPV perpetrators. The Cochrane Handbook for Systemic Reviews of Interventions guidelines for the process of conducting systematic reviews and meta-analysis were followed. Pooled together, overall these various intervention programs are effective in reducing violence for male perpetrators of IPV comparing post to pre-intervention [(pooled estimate = -0.85; 95% Confidence Interval (CI) (-1.02 to -0.69)]. Exploratory subgroup analysis revealed that incorporating substance abuse or trauma components to the interventions yielded better results (substance abuse: CI = -3.20 to -1.08 and trauma: CI = -2.63 to -0.30) as compared to programs that did not have these components. Gender-role based batterer intervention programs yielded mixed results. Analysis of the three controlled studies with 223 participants comparing batterer programs to a minimal control group showed mixed effects. In conclusion, treatment strategies that are addressing highly comorbid issues such as substance abuse and trauma issues may work more effectively in preventing violence.

A randomized clinical trial of motivational enhancement therapy for alcohol problems in partner violent men

This study examined the efficacy of brief alcohol intervention in the context of community-based treatment for partner violence. In a randomized clinical trial, 228 partner-violent men with hazardous or problem drinking were recruited at three Intimate Partner Violence (IPV) treatment agencies and randomly assigned to receive one of two 4-session alcohol interventions: Motivational Enhancement Therapy (MET: N = 110) or Alcohol Education (AE: N = 118). After completing alcohol intervention, participants received standard agency counseling services for IPV. Participants completed assessments of alcohol use, drug use, and IPV at pre-treatment, post-alcohol intervention, and quarterly follow-ups for 12 months. At the end of the 4-session alcohol intervention, MET participants displayed greater acknowledgment of problems with alcohol than AE participants (Partial ή² = 0.039, p = 0.006). Significant changes from baseline across treatment conditions (at p < 0.001) were observed for percent days of alcohol abstinence [95% empirical CI for Partial ή² =0.226, 0.296], heavy drinking [0.292, 0.349], illicit drug use [0.096, 0.156] and partner violence [0.282, 0.334]. No significant condition differences (treatment by time interactions) were found for alcohol abstinence [95% empirical CI for Partial ή² = 0.007, 0.036], heavy drinking [0.016, 0.055], illicit drug use [0.005, 0.035] or partner violence [0.001, 0.004]. Results encourage continued use of brief alcohol interventions in community IPV services, but do not provide evidence of a unique benefit of MET in reducing alcohol use in this population.

What Can Elder Mistreatment Researchers Learn About Primary Prevention From Family Violence Intervention Models?

Elder mistreatment (EM) is a public health problem that harms millions of older Americans each year. Despite growing recognition of its occurrence, there are no evidence-based primary prevention programs. Although EM is distinct from other areas of family violence, including child maltreatment and intimate partner violence, common risk factors and theoretical underpinnings point to opportunities for prevention strategies. Drawing on evidence-based best practices found in other fields of family violence, we identify approaches that could be tested to prevent EM at the hands of family caregivers, who are among the most likely to commit mistreatment. Specifically, we examine home visiting approaches primarily used in the child maltreatment field and identify components that have potential to inform EM interventions, including prevention. We conclude that there is enough information to begin testing a prevention intervention for EM that targets caregivers.

Association Between Substance Use and Gun-Related Behaviors

Gun-related violence is a public health concern. This study synthesizes findings on associations between substance use and gun-related behaviors. Searches through PubMed, Embase, and PsycINFO located 66 studies published in English between 1992 and 2014. Most studies found a significant bivariate association between substance use and increased odds of gun-related behaviors. However, their association after adjustment was mixed, which could be attributed to a number of factors such as variations in definitions of substance use and gun activity, study design, sample demographics, and the specific covariates considered. Fewer studies identified a significant association between substance use and gun access/possession than other gun activities. The significant association between nonsubstance covariates (e.g., demographic covariates and other behavioral risk factors) and gun-related behaviors might have moderated the association between substance use and gun activities. Particularly, the strength of association between substance use and gun activities tended to reduce appreciably or to become nonsignificant after adjustment for mental disorders. Some studies indicated a positive association between the frequency of substance use and the odds of engaging in gun-related behaviors. Overall, the results suggest a need to consider substance use in research and prevention programs for gun-related violence.

Domestic Violence Perpetrator Programs: A Proposal for Evidence-Based Standards in the United States

In the United States, the judicial system response to violence between intimate partners, or intimate partner violence (IPV), typically mandates that adjudicated perpetrators complete a batterer intervention program (BIP). The social science data has found that these programs, on the whole, are only minimally effective in reducing rates of IPV. The authors examined the social science literature on the characteristics and efficacy of BIPs. More than 400 studies were considered, including a sweeping, recently conducted survey of BIP directors across the United States and Canada. Results of this review indicate that the limitations of BIPs are due, in large part, to the limitations of current state standards regulating these programs and, furthermore, that these standards are not grounded in the body of empirical research evidence or best practices. The authors, all of whom have considerable expertise in the area of domestic violence perpetrator treatment, conducted an exhaustive investigation of the following key intervention areas: overall effectiveness of BIPs; length of treatment/length of group sessions; number of group participants and number of facilitators; group format and curriculum; assessment protocol and instruments; victim contact; modality of treatment; differential treatment; working with female perpetrators; working with perpetrators in racial and ethnic minority groups; working with lesbian, gay, bisexual, and transgender (LGBT) perpetrators; perpetrator treatment and practitioner–client relationships; and required practitioner education and training. Recommendations for evidence-based national BIP standards were made based on findings from this review.

Emergency Department Visits and Injury Hospitalizations for Female and Male Victims and Perpetrators of Intimate Partner Violence

Introduction. The potential for hospital-based interventions for male victims of intimate partner violence (IPV) as well as adult perpetrators of both genders has been largely unexplored despite early evidence of acute-care utilization that may be as high as female victims. The current investigation compared the emergency department (ED) and injury-related-hospitalization rates of IPV-involved individuals against standardized national norms, assessing differences by gender and victim/perpetrator-status. Methods. This cross-sectional study collected one-year ED and in-patient visit data from hospital records for individuals listed as victim or perpetrator in an IPV criminal charging request in a Midwestern county (N=2,937). Expected rates were calculated based upon age-adjusted national norms. Results. The IPV-involved population generated ED rates 4.1 times higher than expected and injury-related-hospitalization rates that were 4.0 times higher than expected. Bi-directionally-violent individuals (both victim and perpetrator in IPV charges) consistently had the highest utilization rates (ED 8.4 RR, injury-hospitalization 22.5 RR). Victims, primarily female, had higher ED-visits than perpetrators, primarily male (victims = 4.6 RR, perpetrator = 3.1 RR). Perpetrators, though, had higher injury hospitalizations (victims = 0.8RR, perpetrators = 5.5 RR). Conclusions. Substantial opportunities exist within acute-care medical settings to intervene with IPV-involved women, men, victims, and perpetrators, although the magnitude of the opportunity varied by setting, gender and victim/perpetrator-status.

Pharmacological interventions for drug-using offenders

BACKGROUND

The review represents one in a family of four reviews focusing on a range of different interventions for drug-using offenders. This specific review considers pharmacological interventions aimed at reducing drug use or criminal activity, or both, for illicit drug-using offenders.

OBJECTIVES

To assess the effectiveness of pharmacological interventions for drug-using offenders in reducing criminal activity or drug use, or both.

SEARCH METHODS

We searched Fourteen electronic bibliographic databases up to May 2014 and five additional Web resources (between 2004 and November 2011). We contacted experts in the field for further information.

SELECTION CRITERIA

We included randomised controlled trials assessing the efficacy of any pharmacological intervention a component of which is designed to reduce, eliminate or prevent relapse of drug use or criminal activity, or both, in drug-using offenders. We also report data on the cost and cost-effectiveness of interventions.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures as expected by Cochrane.

MAIN RESULTS

Fourteen trials with 2647 participants met the inclusion criteria. The interventions included in this review report on agonistic pharmacological interventions (buprenorphine, methadone and naltrexone) compared to no intervention, other non-pharmacological treatments (e.g. counselling) and other pharmacological drugs. The methodological trial quality was poorly described, and most studies were rated as 'unclear' by the reviewers. The biggest threats to risk of bias were generated through blinding (performance and detection bias) and incomplete outcome data (attrition bias). Studies could not be combined all together because the comparisons were too different. Only subgroup analysis for type of pharmacological treatment were done. When compared to non-pharmacological, we found low quality evidence that agonist treatments are not effective in reducing drug use or criminal activity, objective results (biological) (two studies, 237 participants (RR 0.72 (95% CI 0.51 to 1.00); subjective (self-report), (three studies, 317 participants (RR 0.61 95% CI 0.31 to 1.18); self-report drug use (three studies, 510 participants (SMD: -0.62 (95% CI -0.85 to -0.39). We found low quality of evidence that antagonist treatment was not effective in reducing drug use (one study, 63 participants (RR 0.69, 95% CI 0.28 to 1.70) but we found moderate quality of evidence that they significantly reduced criminal activity (two studies, 114 participants, (RR 0.40, 95% CI 0.21 to 0.74).Findings on the effects of individual pharmacological interventions on drug use and criminal activity showed mixed results. In the comparison of methadone to buprenorphine, diamorphine and naltrexone, no significant differences were displayed for either treatment for self report dichotomous drug use (two studies, 370 participants (RR 1.04, 95% CI 0.69 to 1.55), continuous measures of drug use (one study, 81 participants, (mean difference (MD) 0.70, 95% CI -5.33 to 6.73); or criminal activity (one study, 116 participants, (RR 1.25, 95% CI 0.83 to 1.88) between methadone and buprenorphine. Similar results were found for comparisons with diamorphine with no significant differences between the drugs for self report dichotomous drug use for arrest (one study, 825 participants, (RR 1.25, 95% CI 1.03 to 1.51) or naltrexone for dichotomous measures of reincarceration (one study, 44 participants, (RR 1.10, 95% CI 0.37 to 3.26), and continuous outcome measure of crime, (MD -0.50, 95% CI -8.04 to 7.04) or self report drug use (MD 4.60, 95% CI -3.54 to 12.74).

AUTHORS' CONCLUSIONS

When compared to non-pharmacological treatment, agonist treatments did not seem effective in reducing drug use or criminal activity. Antagonist treatments were not effective in reducing drug use but significantly reduced criminal activity. When comparing the drugs to one another we found no significant differences between the drug comparisons (methadone versus buprenorphine, diamorphine and naltrexone) on any of the outcome measures. Caution should be taken when interpreting these findings, as the conclusions are based on a small number of trials, and generalisation of these study findings should be limited mainly to male adult offenders. Additionally, many studies were rated at high risk of bias.

Interventions for drug-using offenders with co-occurring mental illness

BACKGROUND

This is an updated version of an original Cochrane review published in Issue 3 2006 (Perry 2006). The review represents one from a family of four reviews focusing on interventions for drug-using offenders. This specific review considers interventions aimed at reducing drug use or criminal activity, or both for drug-using offenders with co-occurring mental illness.

OBJECTIVES

To assess the effectiveness of interventions for drug-using offenders with co-occurring mental illness in reducing criminal activity or drug use, or both.

SEARCH METHODS

We searched 14 electronic bibliographic databases up to May 2014 and 5 Internet resources (searched between 2004 and 11 November 2009). We contacted experts in the field for further information.

SELECTION CRITERIA

We included randomised controlled trials designed to reduce, eliminate, or prevent relapse of drug use and criminal activity, or both in drug-using offenders with co-occurring mental illness. We also reported data on the cost and cost-effectiveness of interventions.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by The Cochrane Collaboration.

MAIN RESULTS

Eight trials with 2058 participants met the inclusion criteria. The methodological quality of the trials was generally difficult to rate due to a lack of clear reporting. On most 'Risk of bias' items, we rated the majority of studies as unclear. Overall, we could not statistically combine the results due to the heterogenous nature of the different study interventions and comparison groups. A narrative summary of the findings identified that the interventions reported limited success with reducing self report drug use, but did have some impact on re-incarceration rates, but not re-arrest. In the single comparisons, we found moderate-quality evidence that therapeutic communities determine a reduction in re-incarceration but reported less success for outcomes of re-arrest, moderate quality of evidence and self report drug use. Three single studies evaluating case management via a mental health drug court (very low quality of evidence), motivational interviewing and cognitive skills (low and very low quality of evidence) and interpersonal psychotherapy (very low quality of evidence) did not report significant reductions in criminal activity and self report drug use respectively. Quality of evidence for these three types of interventions was low to very low. The trials reported some cost information, but it was not sufficient to be able to evaluate the cost-effectiveness of the interventions.

AUTHORS' CONCLUSIONS

Two of the five trials showed some promising results for the use of therapeutic communities and aftercare, but only in relation to reducing subsequent re-incarceration. Overall, the studies showed a high degree of variation, warranting a degree of caution in the interpretation of the magnitude of effect and direction of benefit for treatment outcomes. More evaluations are required to assess the effectiveness of interventions for drug-using offenders with co-occurring mental health problems.

Interventions for female drug-using offenders

BACKGROUND

This is an updated version of a Cochrane review first published in Issue 3, 2006 (Perry 2006). The review represents one in a family of four reviews focusing on the effectiveness of interventions in reducing drug use and criminal activity for offenders. This specific review considers interventions for female drug-using offenders.

OBJECTIVES

To assess the effectiveness of interventions for female drug-using offenders in reducing criminal activity, or drug use, or both.

SEARCH METHODS

We searched 14 electronic bibliographic databases up to May 2014 and five additional Website resources (between 2004 and November 2011). We contacted experts in the field for further information.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) designed to reduce, eliminate or prevent relapse of drug use or criminal activity in female drug-using offenders. We also reported data on the cost and cost-effectiveness of interventions.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by The Cochrane Collaboration.

MAIN RESULTS

Nine trials with 1792 participants met the inclusion criteria. Trial quality and risks of bias varied across each study. We rated the majority of studies as being at 'unclear' risk of bias due to a lack of descriptive information. We divided the studies into different categories for the purpose of meta-analyses: for any psychosocial treatments in comparison to treatment as usual we found low quality evidence that there were no significant differences in arrest rates, (two studies; 489 participants; risk ratio (RR) 0.82, 95% confidence interval (CI) 0.45 to 1.52) or drug use (one study; 77 participants; RR 0.65, 95% CI 0.20 to 2.12), but we found moderate quality evidence that there was a significant reduction in reincarceration, (three studies; 630 participants; RR 0.46, 95% CI 0.34 to 0.64). Pharmacological intervention using buprenorphine in comparison to a placebo did not significantly reduce self reported drug use (one study; 36 participants; RR 0.58, 95% CI 0.25 to 1.35). No cost or cost-effectiveness evidence was reported in the studies.

AUTHORS' CONCLUSIONS

Three of the nine trials show a positive trend towards the use of any psychosocial treatment in comparison to treatment as usual showing an overall significant reduction in subsequent reincarceration, but not arrest rates or drug use. Pharmacological interventions in comparison to a placebo did not significantly reduce drug use and did not measure criminal activity. Four different treatment comparisons showed varying results and were not combined due to differences in the intervention and comparison groups. The studies overall showed a high degree of heterogeneity for types of comparisons and outcome measures assessed, which limited the possibility to pool the data. Descriptions of treatment modalities are required to identify the important elements for treatment success in drug-using female offenders. More trials are required to increase the precision of confidence with which we can draw conclusions about the effectiveness of treatments for female drug-using offenders.

The effectiveness of telephone counselling in the treatment of illicit drug and alcohol use concerns

INTRODUCTION

Technology-assisted substance use interventions such as 'high-tech' internet-based treatments are thought to be effective; however, the relatively 'low-tech' use of telephone counselling does not yet have an established evidence base. This paper reviews the literature including articles with information on the use of telephone counselling for the treatment of illicit drug or alcohol use.

METHODS

A systematic literature search using a set of telephone counselling and substance-related terms was conducted across four electronic databases. English studies prior to June 2014 that involved the use of telephone counselling with the treatment of illicit drug or alcohol use as a primary or secondary outcome were included. Review papers, opinion pieces, letters or editorials, case studies, published abstracts, and posters were excluded. In all, 94 publications were included in the review.

RESULTS AND DISCUSSION

The literature was supportive of telephone counselling for the treatment of alcohol use in the short term; however, literature regarding illicit drug use was particularly scarce. The generalisability of findings was limited by evident methodological issues in the included studies.

Hostility and substance use in relation to intimate partner violence and parenting among fathers

Intimate partner violence (IPV) is a significant public health and economic problem, which also increases the risks for child maltreatment. One attribute that may contribute to both IPV and poor parenting is hostility. Moreover, the link between hostility and these outcomes may be mediated by substance use, such that more hostile individuals are at greater risk for using drugs and alcohol, leading them to engage in more aggressive and rejecting behavior toward their partners and children. We tested this possibility in sample of 132 fathers. Additionally, we explored whether hostility and substance use had interactive effects on IPV and parenting by examining moderated-mediation models. The results show that substance use mediated the relationship between hostility and all IPV and parenting outcomes. Furthermore, this mediated relationship was moderated by substance use level for parenting outcomes, but not IPV. In the case of parenting, the mediated path from hostility to aggressive and rejecting parenting only occurred for those high in substance use. Limitations and implications for prevention and treatment of IPV and aggressive and rejecting parenting are discussed. Aggr. Behav. 41:205-213, 2015. © 2014 Wiley Periodicals, Inc.

Alcohol interventions, alcohol policy and intimate partner violence: a systematic review

BACKGROUND

Intimate partner violence (IPV) is a significant global public health issue. The consistent evidence that alcohol use by one or both partners contributes to the risk and severity of IPV suggests that interventions that reduce alcohol consumption may also reduce IPV. This study sought to review the evidence for effects on IPV of alcohol interventions at the population, community, relationship and individual levels using the World Health Organization ecological framework for violence.

METHODS

Eleven databases including Medline, PsycINFO, CINAHL and EMBASE were searched for English-language studies and grey literature published 1 January 1992 - 1 March 2013 investigating whether alcohol interventions/policies were associated with IPV reduction within adult (≥ 18) intimate relationships. Eleven studies meeting design criteria for attributing effects to the intervention and ten studies showing mediation of alcohol consumption were included in the review. The heterogeneity of study designs precluded quantitative meta analysis; therefore, a critical narrative approach was used.

RESULTS

Population-level pricing and taxation studies found weak or no evidence for alcohol price changes influencing IPV. Studies of community-level policies or interventions (e.g., hours of sale, alcohol outlet density) showed weak evidence of an association with IPV. Couples-based and individual alcohol treatment studies found a relationship between reductions in alcohol consumption and reductions in IPV but their designs precluded attributing changes to treatment. Randomized controlled trials of combined alcohol and violence treatment programs found some positive effects of brief alcohol intervention as an adjunct to batterer treatment for hazardous drinking IPV perpetrators, and of brief interventions with non-dependent younger populations, but effects were often not sustained.

CONCLUSIONS

Despite evidence associating problematic alcohol use with IPV, the potential for alcohol interventions to reduce IPV has not been adequately tested, possibly because studies have not focused on those most at risk of alcohol-related IPV. Research using rigorous designs should target young adult populations among whom IPV and drinking is highly prevalent. Combining alcohol and IPV intervention/policy approaches at the population, community, relationship and individual-level may provide the best opportunity for effective intervention.

Cognitive-behavioral therapy in depressed primary care patients with co-occurring problematic alcohol use: effect of telephone-administered vs. face-to-face treatment-a secondary analysis

This secondary analysis of a larger study compared adherence to telephone-administered cognitive-behavioral therapy (T-CBT) vs. face-to-face CBT and depression outcomes in depressed primary care patients with co-occurring problematic alcohol use. To our knowledge, T-CBT has never been directly compared to face-to-face CBT in such a sample of primary care patients. Participants were randomized in a 1:1 ratio to face-to-face CBT or T-CBT for depression. Participants receiving T-CBT (n = 50) and face-to-face CBT (n = 53) were compared at baseline, end of treatment (week 18), and three-month and six-month follow-ups. Face-to-face CBT and T-CBT groups did not significantly differ in age, sex, ethnicity, marital status, educational level, severity of depression, antidepressant use, and total score on the Alcohol Use Disorders Identification Test. Face-to-face CBT and T-CBT groups were similar on all treatment adherence outcomes and depression outcomes at all time points. T-CBT and face-to-face CBT had similar treatment adherence and efficacy for the treatment of depression in depressed primary care patients with co-occurring problematic alcohol use. When targeting patients who might have difficulties in accessing care, primary care clinicians may consider both types of CBT delivery when treating depression in patients with co-occurring problematic alcohol use.

Interventions for female drug-using offenders

BACKGROUND

This is an updated version of a Cochrane review first published in Issue 3, 2006 (Perry 2006). The review represents one in a family of four reviews focusing on the effectiveness of interventions in reducing drug use and criminal activity for offenders. This specific review considers interventions for female drug-using offenders.

OBJECTIVES

To assess the effectiveness of interventions for female drug-using offenders in reducing criminal activity or drug use, or both.

SEARCH METHODS

We searched 14 electronic bibliographic databases (between 2004 and 21st March 2013) and five additional web resources (between 2004 and November 2011). We contacted experts in the field for further information.

SELECTION CRITERIA

We include randomised controlled trials designed to reduce, eliminate or prevent relapse in female drug-using offenders. We also report data on the cost and cost effectiveness of interventions.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by the Cochrane Collaboration.

MAIN RESULTS

We identified 76 trials across the four reviews. Following a process of prescreening, we judged that 11 trials met the inclusion criteria of the specified review; four of the 11 trials are awaiting classification in the review. The remaining seven trials cover 1236 participants. The interventions included in this review report on therapeutic communities (TCs), gender-responsive treatment (GRT), use of case management and cognitive skills, and a pharmacological intervention using buprenorphine. Trial quality and risks of bias varied across each study. The majority of studies were rated as being at 'unclear' risk of bias due to a lack of descriptive information. Overall the interventions showed statistically significant reductions in self-reported drug use, (four studies, 734 participants, risk ratio (RR) 0.68; 95% confidence interval (CI) 0.58 to 0.80) and re-incarceration, (four studies, 745 participants, RR 0.55; 95% CI 0.41 to 0.72). We found a statistically non-significant result for re-arrest (three studies, 803 participants, RR 0.80; 95% CI 0.53 to 1.19). Individual treatment results found that TCs and a GRT programme showed a statistically significant reduction in re-incarceration (one study, 509 participants, RR 0.42; 95% CI 0.29 to 0.60) but not for re-arrest, (one study, 314 participants, RR 0.73; 95% CI 0.52 to 1.03) and self-reported drug use (two studies, 825 participants, RR 0.47; 95% CI 0.14 to 1.53). Case management and cognitive skills programmes did not significantly reduce re-arrests, (one study, 183 participants RR 1.12; 95% CI 0.89 to 1.41) or self-reported drug use, (one study, 77 participants, RR 0.65; 95% CI 0.20 to 2.12), but did show a statistically significant reduction in re-incarceration, (three studies, 236 participants, RR 0.63; 95% CI 0.49 to 0.81). Buprenorphine did not significantly reduce self-reported drug use (RR 0.58; 95% CI 0.25 to 1.35), but this result came from a single study with only 36 participants. Due to the small number of studies we were unable to analyse the impact of treatment setting on outcome. No cost and cost effectiveness evidence was reported in the studies.

AUTHORS' CONCLUSIONS

The seven trials show some positive results for the use of treatments to reduce self-reported drug use and subsequent re-incarceration. However, the studies overall showed a high degree of statistical variation, requiring a degree of caution in the interpretation of the magnitude of effect and direction of benefit for treatment outcomes. Descriptions of treatment modalities are required to identify the important elements for treatment success in drug-using female offenders. More trials are required to increase the confidence with which we can draw conclusions about the effectiveness of treatments for female drug-using offenders.

Interventions for drug-using offenders with co-occurring mental illness

BACKGROUND

This is an updated version of an original Cochrane review published in Issue 3 2006 (Perry 2006). The review represents one from a family of four reviews focusing on interventions for drug-using offenders. This specific review considers interventions aimed at reducing drug use or criminal activity, or both for drug-using offenders with co-occurring mental illness.

OBJECTIVES

To assess the effectiveness of interventions for drug-using offenders with co-occurring mental illness in reducing criminal activity or drug use, or both.

SEARCH METHODS

We searched 14 electronic bibliographic databases (searched between 2004 and 21 March 2013) and five internet resources (searched between 2004 and 11 November 2009). We contacted experts in the field for further information.

SELECTION CRITERIA

We included randomised controlled trials designed to reduce, eliminate or prevent relapse in drug-using offenders with co-occurring mental illness. We also reported data on the cost and cost effectiveness of interventions.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by The Cochrane Collaboration.

MAIN RESULTS

We identified 76 trials across the four reviews. Following a process of pre-screening, we judged eight trials to meet the inclusion criteria for this specific review (three of the five trials are awaiting classification). The five included 1502 participants. The interventions reported on case management via a mental health drugs court, a therapeutic community, and an evaluation of a motivational interviewing technique and cognitive skills in comparison to relaxation training. The methodological quality of the trials was generally difficult to rate due to a lack of clear reporting. On most risk of bias items, we rated the majority of studies as unclear. Overall, the combined interventions did not show a statistically significant reduction in self reported drug use (2 studies, 715 participants; risk ratio (RR) 0.82, 95% confidence interval (CI) 0.44 to 1.55). A statistically significantly reduction was shown for re-incarceration (4 studies, 627 participants; RR 0.40, 95% CI 0.24 to 0.67 and mean difference (MD) 28.72, 95% CI 5.89 to 51.54) but not re-arrest (2 studies, 518 participants; RR 1.00, 95% CI 0.90 to 1.12). A specific subgroup analysis combining studies using therapeutic community interventions showed a statistically significant reduction in re-incarceration (2 studies, 266 participants; RR 0.29, 95% CI 0.16 to 0.54) but not re-arrest (1 study, 428 participants; RR 0.90, 95% CI 0.61 to 1.33). Case management via a mental health court and motivational interviewing with cognitive skills did not show a statistically significant reduction in criminal activity (1 study, 235 participants; RR 1.05, 95% CI 0.90 to 1.22) or self reported drug misuse (1 study, 162 participants; MD -7.42, 95% CI -20.12 to 5.28). Due to the small number of studies, we were unable to analyse the impact of setting on outcome. Some cost information was provided in the trials but not sufficient to be able to evaluate the cost effectiveness of the interventions.

AUTHORS' CONCLUSIONS

This review highlights the paucity of evidence for drug misusing offenders with co-occurring mental health problems. Two of the five trials showed some promising results for the use of therapeutic communities and aftercare, but only in relation to reducing subsequent re-incarceration. The studies overall, showed a high degree of statistical variation demonstrating a degree of caution in the interpretation of the magnitude of effect and direction of benefit for treatment outcomes. More evaluations are required to assess the effectiveness of interventions for drug-using offenders with co-occurring mental health problems.

Pharmacological interventions for drug-using offenders

BACKGROUND

The review represents one in a family of four reviews focusing on a range of different interventions for drug-using offenders. This specific review considers pharmacological interventions aimed at reducing drug use and/or criminal activity for illicit drug-using offenders.

OBJECTIVES

To assess the effectiveness of pharmacological interventions for drug-using offenders in reducing criminal activity and/or drug use.

SEARCH METHODS

Fourteen electronic bibliographic databases (searched between 2004 and 21 March 2013) and five additional Web resources (searched between 2004 and 11 November 2011) were searched. Experts in the field were contacted for further information.

SELECTION CRITERIA

Randomised controlled trials assessing the efficacy of any pharmacological interventions for reducing, eliminating or preventing relapse in drug-using offenders were included. Data on the cost and cost-effectiveness of interventions were reported.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures as expected by The Cochrane Collaboration.

MAIN RESULTS

A total of 76 trials across the four reviews were identified. After a process of prescreening had been completed, 17 trials were judged to meet the inclusion criteria for this specific review (six of the 17 trials are awaiting classification for the review). The remaining 11 trials contained a total of 2,678 participants. Nine of the eleven studies used samples with a majority of men. The interventions (buprenorphine, methadone and naltrexone) were compared to non pharmacological treatments (e.g., counselling) and other pharmacological drugs. The methodological trial quality was poorly described, and most studies were rated as 'unclear' by the reviewers. The biggest threats to risk of bias were generated through blinding (performance and detection bias) and incomplete outcome data (attrition bias). When combined, the results suggest that pharmacological interventions do significantly reduce subsequent drug use using biological measures, (three studies, 300 participants, RR 0.71 (95% CI 0.52 to 0.97)), self report dichotomous data (three studies, 317 participants, RR 0.42, (95% CI 0.22 to 0.81)) and continuous measures (one study, MD -59.66 (95% CI -120.60 to 1.28)) . In the subgroups analysis for community setting, (two studies, 99 participants: RR 0.62 (95% CI 0.35 to 1.09)) and for secure establishment setting, (one study, 201 participants: RR 0.76 (95% CI 0.52 to 1.10)), the results are no longer statistically significant. Criminal activity was significantly reduced favouring the dichotomous measures of re arrest, (one study, 62 participants, RR 0.60 (95% CI 0.32 to 1.14)), re-incarceration, (three studies, 142 participants, RR 0.33 (95% CI 0.19 to 0.56)) and continuous measures (one study, 51 participants, MD -74.21 (95% CI -133.53 to -14.89)). Findings on the effects of individual pharmacological interventions on drug use and criminal activity show mixed results. Buprenorphine in comparison to a non pharmacological treatment seemed to favour buprenorphine but not significantly with self report drug use, (one study, 36 participants, RR 0.58 (95% CI 0.25 to 1.35)). Methadone and cognitive behavioural skills in comparison to standard psychiatric services, did show a significant reduction for self report dichotomous drug use (one study, 253 participants, RR 0.43 (95% CI 0.33 to 0.56)) but not for self report continuous data (one study 51 participants) MD -0.52 (95% CI -1.09 to 0.05)), or re incarceration RR 1.23 (95% CI 0.53 to 2.87)). Naltrexone was favoured significantly over routine parole and probation for re incarceration (two studies 114 participants, RR 0.36 (95% CI 0.19 to 0.69)) but no data was available on drug use. Finally, we compared each pharmacological treatment to another. In each case we compared methadone to: buprenorphine, diamorphine and naltrexone. No significant differences were displayed for either treatment for self report dichotomous drug use (one study, 193 participants RR 1.23 (95% CI 0.86 to 1.76)), continuous measures of drug use MD 0.70 (95% CI -5.33 to 6.73) or criminal activity RR 1.25 (95% CI 0.83 to 1.88)) between methadone and buprenorphine. Similiar results were found for comparisons with Diamorphine with no significant differences between the drugs for self report dichotomous drug use for arrest (one study, 825 participants RR 1.25 (95% CI 1.03-1.51)) or Naltrexone for dichotomous measures of re incarceration (one study, 44 participants, RR 1.10 (95% CI 0.37 to 3.26)), and continuous outcome measure of crime MD -0.50 (95% CI -8.04 to 7.04)) or self report drug use MD 4.60 (95% CI -3.54 to 12.74)).

AUTHORS' CONCLUSIONS

Pharmacological interventions for drug-using offenders do appear to reduce overall subsequent drug use and criminal activity (but to a lesser extent). No statistically significant differences were displayed by treatment setting. Individual differences are displayed between the three pharmacological interventions (buprenorphine, methadone and naltrexone) when compared to a non pharmacological intervention, but not when compared to each other. Caution should be taken when interpreting these findings, as the conclusions are based on a small number of trials, and generalisation of these study findings should be limited mainly to male adult offenders. Additionally, many studies were rated at high risk of bias because trial information was inadequately described.

A Self-Determination Model of Childhood Exposure, Perceived Prevalence, Justification, and Perpetration of Intimate Partner Violence

The present research was designed to evaluate self-determination theory as a framework for integrating factors associated with intimate partner violence (IPV) perpetration. The proposed model suggests that childhood exposure to parental violence may influence global motivational orientations which, in turn result in greater cognitive biases (overestimating the prevalence of IPV and justification of IPV) which, in turn, contribute to an individual's decision to use abusive behavior. Participants included 124 men who had engaged in abusive behavior toward an intimate partner. Results provided reasonable support for the proposed model and stronger support for a revised model suggesting that controlled orientation, rather than autonomy orientation, appears to play a stronger role in the association between childhood exposure to parental violence and cognitive biases associated with abusive behavior.

EXPOSURE TO DOMESTIC VIOLENCE AND CHILDHOOD EMOTIONAL ABUSE: Childhood Domestic Violence Exposure among a Community Sample of Adult Perpetrators: What Mediates the Connection?

The association between childhood exposure to domestic violence and later intimate partner violence (IPV) perpetration in adulthood has been well established in the literature. However, the literature examining the factors of exposure that contribute to perpetration in adulthood is fraught with mixed findings, with some studies finding a direct link between childhood domestic violence exposure and later IPV perpetration and others ruling out a link after controlling for other contextual barriers such as community violence and socioeconomic status. This study examined 124 non-treatment-seeking and unadjudicated adult male IPV perpetrators and found exposure to domestic violence in childhood contributes to the normalization of violence, which could predict future adult IPV perpetration. Practice implications are discussed, namely primary and secondary prevention of intimate partner violence.
