The effectiveness of interventions to prevent recidivism in perpetrators of intimate partner violence: A systematic review and meta-analysis

A Systematic Review of the Quality of Perpetrator Programs' Outcome Studies: Toward A New Model of Outcome Measurement

This systematic review assessed whether studies on the outcomes of perpetrator programs comply with the model recommendations for outcome evaluation. Three databases (PsycINFO, Medline, and Scopus) were used to identify perpetrator program outcome studies from 1988 to 2021. The inclusion criteria were as follows: empirical studies with no time restriction; published in English or Spanish; evaluated interventions aimed at male perpetrators of any type of abuse toward women; evaluated the effectiveness of the intervention in a follow-up post-intervention; and provided an indicator of recidivism. The search and selection process resulted in 46 original studies. The results showed that studies did not include a thorough description of the study sample. Many approaches to psychological intervention are used, with cognitive behavioral therapy being the most widely used. Most studies did not describe the program content. Dropout rates varied greatly from one study to another (from 0% to 64%) and only eight studies provided dropout rates specified by each type of perpetrator. The follow-up period ranged from 3 months to 9 years. The recidivism rates (ranging from 5% to 72.5%), and their assessments were also very different. Only 12 of the 46 studies (26.1%) used more than one source to obtain recidivism rates. In terms of outcomes, few studies considered (ex-) partner accounts. Some studies had other measures of outcome, whereas a few included a pretest-posttest. In summary, these studies do not follow the recommendations of the model.

Which battering interventions work? An updated Meta-analytic review of intimate partner violence treatment outcome research

This meta-analytic review is an update to the first meta-analysis of battering interventions (Babcock et al., 2004) and includes 59 studies that evaluated treatment efficacy for domestically violent men and women. The outcome literature of controlled quasi-experimental and experimental studies was reviewed to test the relative impact of Duluth, cognitive-behavioral therapy (CBT), and novel types of treatment on subsequent recidivism of violence. The first model examines studies comparing interventions to no treatment control conditions. The second model compares novel interventions to treatment as usual (i.e., the Duluth curriculum). Study design and type of treatment were tested as moderators in both models. Consistent with previous meta-analyses, effect sizes were in the small range, smaller in true experiments as compared to quasi-experimental designs when recidivism was based on partner or police reports. However, new experiments comparing novel treatments to the Duluth curriculum reveal effect sizes comparable to when comparing novel interventions to an untreated comparison group. Novel interventions, including Acceptance and Commitment Therapy and Circles of Peace had the largest effect sizes when put head-to-head with Duluth control groups. Future research directions include testing moderators and mechanisms of change of the battering interventions that work. Implications for evidence-based practice in criminal justice include broader implementation and continued testing of these novel interventions with demonstrated efficacy in stopping intimate partner violence.

Biopsychosocial risk factors for intimate partner violence perpetration and victimization in adolescents and adults reported after the COVID-19 pandemic onset: a scoping review protocol

OBJECTIVE

This scoping review aims to provide a comprehensive summary of the biological, psychological, and sociological risk factors for intimate partner violence (IPV) victimization and perpetration reported after the onset of the COVID-19 pandemic.

INTRODUCTION

IPV is a significant public health concern, characterized by various forms of violence inflicted by intimate partners. The onset of the COVID-19 pandemic significantly increased the global prevalence of IPV. While prior research has identified factors linked to IPV, the risk factors reported in the literature during this period have not been systematically mapped. Additionally, the similarities and differences in risk factors between perpetration and victimization have not been well delineated.

INCLUSION CRITERIA

This review will focus on individuals aged 12 years or older involved in dyadic romantic relationships. Primary studies and systematic reviews published from the year 2020 will be included. Full-text papers, preprints, theses, and dissertations published in English will be included. Studies focusing on factors unrelated to IPV risk will be excluded. Non-systematic reviews, opinion pieces, and protocols will also be excluded.

METHODS

Following the JBI methodology for scoping reviews, systematic searches will be conducted for both peer-reviewed and gray literature. Independent reviewers will screen records, select eligible studies, and extract data using a standardized form. Key risk factors will be mapped to explore their interplay.

Beyond the Initial Assault: Characterizing Revictimization in Intimate Partner Violence and Its Implications for Women's Health

Recent research has emphasized the importance of addressing specific victim-related factors to reduce victims' vulnerability and prevent future revictimization experiences. This study aimed to analyze the vulnerability profiles of women who were victims of intimate partner violence, including those who had experienced a single incident of violence and those who had endured revictimization. Participants were 338 women with active judicial protection measures registered in the system of support for victims of gender violence (VioGén) in Madrid, Spain. The analysis considered sociodemographic characteristics, victimization history, perceived triggers of violence, women's responses and feelings, as well as clinical outcomes linked to revictimization history. The study revealed that many victims faced socioeconomic vulnerability. Furthermore, the findings underscored the intricate link between the likelihood of enduring chronic violence and women's awareness of early indicators of violence risk, their initial responses to aggression, communication skills, and recurrent behaviors in the context of an established violent dynamic. This study offers valuable insights for law enforcement to identify the risk of revictimization. Furthermore, findings raise awareness about the particularly vulnerable situation of some women to repeated victimization experiences and provide relevant information for clinical intervention.

Randomised pilot and feasibility trial of a group intervention for men who perpetrate intimate partner violence against women

BACKGROUND

There is a need for robust evidence on the effectiveness and cost-effectiveness of domestic abuse perpetrator programmes in reducing abusive behaviour and improving wellbeing for victim/survivors. While any randomised controlled trial can present difficulties in terms of recruitment and retention, conducting such a trial with domestic abuse perpetrators is particularly challenging. This paper reports the pilot and feasibility trial of a voluntary domestic abuse perpetrator group programme in the United Kingdom.

METHODS

This was a pragmatic individually randomised pilot and feasibility trial with an integrated qualitative study in one site (covering three local-authority areas) in England. Male perpetrators were randomised to either the intervention or usual care. The intervention was a 23-week group programme for male perpetrators in heterosexual relationships, with an average of three one-to-one sessions, and one-to-one support for female current- or ex-partners delivered by third sector organisations. There was no active control treatment for men, and partners of control men were signposted towards domestic abuse support services. Data were collected at three-monthly intervals for nine months from male and female participants. The main objectives assessed were recruitment, randomisation, retention, data completeness, fidelity to the intervention model, and acceptability of the trial design.

RESULTS

This study recruited 36 men (22 randomly allocated to attend the intervention group programme, 14 to usual care), and 15 current- or ex-partners (39% of eligible partners). Retention and completeness of data were high: 67% of male (24/36), and 80% (12/15) of female participants completed the self-reported questionnaire at nine months. A framework for assessing fidelity to the intervention was developed. In interviews, men who completed all or most of the intervention gave positive feedback and reported changes in their own behaviour. Partners were also largely supportive of the trial and were positive about the intervention. Participants who were not allocated to the intervention group reported feeling disappointed but understood the rationale for the trial.

CONCLUSIONS

It was feasible to recruit, randomise and retain male perpetrators and female victim/survivors of abuse and collect self-reported outcome data. Participants were engaged in the intervention and reported positive benefits. The trial design was seen as acceptable.

The Uptake and Measurement of Alternative Approaches to Domestic Violence Intervention Programs: A Scoping Review

This scoping review explores the breadth and depth to which Domestic Violence Intervention Programs (DVIPs) in the United States and globally: (a) incorporate components that address the relationship between intimate partner violence (IPV) and social injustice, racism, economic inequality, and adverse childhood experiences (ACEs); (b) use restorative (RJ)/transformative justice (TJ) practices, individualized case management, partnerships with social justice actors, and strengths-based parenting training in current programming; and (c) measure effectiveness. In 2021, we searched 12 academic databases using a combination of search terms and Medical Subject Headings. In all, 27 articles that discussed at least one key concept relative to DVIP curricula were included in the final review. Findings suggest that very few DVIPs address ACEs and/or the relationship between structural violence, social inequality, and IPV perpetration. Even fewer programs use restorative practices including RJ or TJ. Furthermore, DVIPs use inconsistent methods and measures to evaluate effectiveness. To respond to IPV perpetration more effectively and create lasting change, DVIPs must adopt evidence-informed approaches that prioritize social and structural determinants of violence, trauma-informed care, and restoration.

Intervention Program Dropout Among Perpetrators of Intimate Partner Violence: A Meta-Analysis of Correlated Variables

Dropout in perpetrator intervention programs (PIPs) is extensively documented in the literature, yet findings across various studies exhibit global inconsistency. This meta-analysis aimed to identify dropout rates among individuals attending PIPs and examine sociodemographic, violence-related, intrapersonal, interpersonal, and external variables related to dropout. A search was conducted across six databases, encompassing studies published between 2010 and 2022 in English, Spanish, or Portuguese. Thirty manuscripts, comprising data from 31 independent samples, were included. Dropout rates varied from 9% to 67%. Bivariate analysis results indicated that younger age (OR = 0.69), non-White ethnicity (OR = 1.54), unemployment (OR = 1.78), offender typology other than family only (OR = 2.45), substance abuse (OR = 1.78), presenting a personality disorder (OR = 1.21), engaging in problematic leisure activities (OR = 1.28), possessing a greater criminal history (OR = 1.47), and experiencing more adversity in childhood (OR = 1.44) were significantly correlated with dropout. Additionally, the inclusion of motivational strategies in treatment (OR = 0.44) significantly decreased the likelihood of dropout. Results from multivariate analyses revealed that younger age (OR = 0.63), presenting a personality disorder (OR = 1.73), and experiencing more adversity in childhood (OR = 2.16) were significantly associated with dropout. Notably, intimate partner violence characteristics established a significant negative relation with dropout (OR = 0.59). Findings indicate that variables associated with dropout align with those related to general and intimate partner violence recidivism, suggesting that individuals requiring more intensive intervention are those who derive less benefit from it.

Group-Related Variables in Intervention Programs for Intimate Partner Violence Perpetrators: A Systematic Review

Intervention programs for male intimate partner violence (IPV) perpetrators mostly use the group intervention modality. Notwithstanding, the literature has neglected the study of group-related variables and their possible association with these interventions' functioning and outcomes. This systematic review aimed to analyze group-related variables, their predictors, and their relation to the functioning and outcomes of intervention programs for IPV perpetrators. The systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The following databases were searched from inception to November 2022: Web of Science, Scopus, PUBMED, and PsycINFO. Of the 5,941 identified studies, 13 were included in the review. The main predictors of group-related variables were: intervention stage, motivational strategies, and leadership (counseling approach). The group-related variables as predictors of intervention outcomes were: group management behaviors and support (facilitator behavior within the group); positive confrontation, protherapeutic behavior, active involvement, positive interaction with peers, and positive interaction with the facilitator (participant behavior within the group); and group cohesion and group climate (group dynamics). Group cohesion and participants' protherapeutic behavior stood out for their association with positive treatment outcomes (i.e., greater participation and working alliance, lower rates of violent behavior during follow-up). The findings from this review suggest that group processes are key factors in intervention programs for IPV perpetrators, and a better understanding of how these group processes are shaped, and how they can contribute to positive program outcomes, provides a new approach and insights to improve their effectiveness.

Adapting the ADVANCE group program for digitally-supported delivery to reduce intimate partner violence by men in substance use treatment: a feasibility study

Introduction

COVID-19 restrictions created barriers to "business as usual" in healthcare but also opened the door to innovation driven by necessity. This manuscript (1) describes how ADVANCE, an in-person group perpetrator program to reduce intimate partner violence (IPV) against female (ex)partners by men in substance use treatment, was adapted for digitally-supported delivery (ADVANCE-D), and (2) explores the feasibility and acceptability of delivering ADVANCE-D to men receiving substance use treatment.

Methods

Firstly, the person-based approach and mHealth development framework were used to iteratively adapt ADVANCE for digitally-supported delivery including conceptualization, formative research, and pre-testing. Then, a non-randomized feasibility study was conducted to assess male participants' eligibility, recruitment, and attendance rates and uptake of support offered to their (ex)partners. Exploratory analyses on reductions in IPV perpetration (assessed using the Abusive Behavior Inventory; ABI) and victimization (using the revised ABI; ABI-R) at the end of the program were performed. Longitudinal qualitative interviews with participants, their (ex)partners, and staff provided an understanding of the program's implementation, acceptability, and outcomes.

Results

The adapted ADVANCE-D program includes one goal-setting session, seven online groups, 12 self-directed website sessions, and 12 coaching calls. ADVANCE-D includes enhanced risk management and support for (ex)partners. Forty-five participants who had perpetrated IPV in the past 12 months were recruited, forty of whom were offered ADVANCE-D, attending 11.4 (SD 9.1) sessions on average. Twenty-one (ex)partners were recruited, 13 of whom accepted specialist support. Reductions in some IPV perpetration and victimization outcome measures were reported by the 25 participants and 11 (ex)partners interviewed pre and post-program, respectively. Twenty-two participants, 11 (ex)partners, 12 facilitators, and 7 integrated support service workers were interviewed at least once about their experiences of participation. Overall, the program content was well-received. Some participants and facilitators believed digital sessions offered increased accessibility.

Conclusion

The digitally-supported delivery of ADVANCE-D was feasible and acceptable. Remote delivery has applicability post-pandemic, providing greater flexibility and access. Given the small sample size and study design, we do not know if reductions in IPV were due to ADVANCE-D, time, participant factors, or chance. More research is needed before conclusions can be made about the efficacy of ADVANCE-D.

Weakened sympathetic response and lower parasympathetic activity in intimate partner violence perpetrators when empathizing: Influence of autonomous activation in affective approach and prosocial behavior

The autonomic nervous system (ANS) functioning has been proposed as a relevant method to characterize the therapeutic needs of intimate partner violence (IPV) perpetrators. Nevertheless, research has neglected the influence of the ANS on socio-affective functions in this population. The aim of the present study was to analyze the psychophysiological activity of IPV perpetrators (n = 52) compared to controls (n = 46) following an empathic induction task, performed through negative emotion-eliciting videos. We employed two general ANS markers (heart rate [HR] and respiratory rate [RR]), two sympathetic-related indexes (pre-ejection period [PEP] and skin conductance level [SCL]) and a parasympathetic biomarker (respiratory sinus arrhythmia [RSA]). Additionally, we explored the impact of psychophysiological activity on prosocial behavior using Hare's donation procedure. Compared to controls, IPV perpetrators reported lower HR and SCL following the task, as well as longer PEP, suggesting an attenuated sympathetic response to others' distress. No differences in the RSA response pattern were found, however, IPV perpetrators displayed lower overall RSA levels throughout the protocol, indicative of reduced parasympathetic activity. Besides, while no differences in prosocial performance were observed, greater sympathetic responses and overall parasympathetic activity predicted increased donations across the sample. Thus, a high sympathetic and parasympathetic activity might influence the occurrence of prosocial behavior. The present study provides further evidence supporting that IPV perpetrators cope differently with others' negative emotions. In line with this biopsychosocial perspective, insights are gained on the emotional processing of IPV perpetrators which, in turn, could contribute to improve IPV psychotherapeutic programs.

Differential Treatment Response of Proactive and Reactive Partner Abusive Men: Results from a Laboratory Proximal Change Experiment

Objective: The current study reexamines data from Babcock et al. (2011) proximal change experiment to discern the differential utility of two communication skills-based interventions for proactive and reactive partner violence offenders. Method: Partner violent men were randomly assigned to the Editing Out the Negative skill, the Accepting Influence skill, or to a placebo/timeout and reengaged in a conflict discussion with their partners. Proactivity was tested as a moderator of immediate intervention outcomes. The ability to learn the communication skills, changes in self-reported affect, observed aggression, and psychophysiological responding were examined as a function of proactivity of violence. Results: Highly proactive men had some difficulty learning the Accepting Influence skill and they responded poorly to this intervention. They responded positively to the Editing Out the Negative technique, with less aggression, more positive affect, and lower heart rates. Low proactive (i.e., reactive) men tended to feel less aggressive, more positive, and less physiologically aroused after completing the Accepting Influence technique. Conclusions: This study lends support for tailoring batterer interventions specific to perpetrator characteristics.

Risk and Protective Factors for Intimate Partner Violence Against Bisexual Victims: A Systematic Scoping Review

Bisexual-identifying individuals appear to be at increased risk of experiencing intimate partner violence (IPV) compared to people of other sexualities. The purpose of this systematic scoping review was to examine risk and protective factors for the perpetration of IPV against bisexual victims and to provide a preliminary quality assessment of the included studies. A systematic search of academic and grey literature was conducted in February 2021. Inclusion criteria specified that study participants identified as bisexual, that the study examined risk or protective factors for IPV, and that findings were disaggregated by sexual identity. All potentially eligible references were independently screened by two reviewers, and conflicts settled by a third reviewer. Nine articles published between 2013 and 2021 met criteria for inclusion. Data extraction was completed for all included studies, and findings presented in a narrative synthesis. The review identified a number of risk factors, including bisexual identity, internalised homophobia, discrimination, partner gender, negative childhood experiences and non-monogamy. One study included consideration of a potentially protective factor. The majority of the included studies were cross-sectional in design. More longitudinal studies are needed to clarify temporality of the associations identified and better inform support and prevention efforts. Further implications for future research, policies and practise are discussed.

Motivational Interview Techniques and the Effectiveness of Intervention Programs With Perpetrators of Intimate Partner Violence: A Systematic Review

Intimate Partner Violence (IPV) is widely recognized as a severe public health issue. Perpetrators' Intervention Programs (PIPs) have been essential to prevent recidivism, and the incorporation of Motivational Interview Techniques (MIT) has shown to be an added value in this area. Objective: The present systematic review aims to analyze the incorporation of MIT (i.e., pre-treatment, isolated treatment, and conjoined with PIPs) in interventions with IPV perpetrators and its potential impact on their behavior and attitudes regarding motivation for change and treatment compliance. Method: The following research equation was used: "Intimate Partner Violence" AND ("Perpetrator" OR "Batterer" OR "Offender") AND ("Motivation" OR "Motivational Interview") AND ("Intervention" OR "Intervention Program" OR "Batterer Intervention Program") AND ("Effectiveness OR "Program Effectiveness"); in four separate databases: PubMed, PsycINFO, Science Direct, and EBSCO. Studies in English, Portuguese, and Spanish were included, and 15 were identified according to the defined inclusion criteria. Results: Studies demonstrated that MIT increases attendance rates, treatment adherence, motivation for change, and behavioral and attitudinal outcomes. More specifically, MIT showed greater effectiveness among participants with low readiness to change and in the early stages of change. Conclusion: This systematic review corroborates the importance of incorporating MIT in PIPs to improve intervention efficacy.

Methodological Challenges in Group-based Randomised Controlled Trials for Intimate Partner Violence Perpetrators: A Meta-summary

Evidence for treatment effects of group-based Intimate Partner Violence (IPV) perpetrators programmes remains, at best, inconclusive. In the present review, systematic/meta-analytic reviews were used to identify randomised controlled trials and a meta-summary approach was employed to identify methodological challenges in the design and conduct of these trials. Of the fifteen studies identified, seven were comparative effectiveness trials. A range of methodological challenges were also identified by the trialists; source of outcome data, treatment modality, attrition and sample characteristics were the most frequently mentioned. Although there are only a few randomised controlled trials compared to non randomised studies, the findings of both highlight the need to invest in the development of innovative and/or combined IPV treatment programmes to address co-occurring issues such as substance use and trauma. The summary of methodological challenges will provide the first step in the development of methods guidance for researchers working in this area.

Effect sizes and effect size benchmarks in family violence research

Scholarly journals increasingly request that authors include effect size (ES) estimates when reporting statistical results. However, there is little guidance on how authors should interpret ESs. Consequently, some authors do not provide ES interpretations, or, when interpretations are provided, they often fail to use appropriate reference groups, using instead the ES benchmarks suggested by Cohen (1988). After discussing the most commonly used ES estimates, we describe the method used by Cohen (1962) to develop ES benchmarks (i.e., small, medium, and large) for use in power analyses and describe the limitations associated with using these benchmarks. Next, we establish general benchmarks for family violence (FV) research. That is, we followed Cohen's approach to establishing his original ES benchmarks using family violence research published in 2021 in Child Abuse & Neglect, which produced a medium ES (d = 0.354) that was smaller than Cohen's recommended medium ES (d = 0.500). Then, we examined the ESs in different subspecialty areas of FV research to provide benchmarks for contextualized FV ESs and to provide information that can be used to conduct power analyses when planning future FV research. Finally, some of the challenges to developing ES benchmarks in any scholarly discipline are discussed. For professionals who are not well informed about ESs, the present review is designed to increase their understanding of ESs and what ES benchmarks tell them (and do not tell them) with respect to understanding the meaningfulness of FV research findings.

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

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.

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.

Intimate Partner Violence: A New Cognitive, Interpersonal and Motivational Framework for the Rehabilitation of Perpetrators in Portugal

Intimate partner violence (IPV) has been targeted as a significant concern worldwide, but evidence for the efficacy of perpetrators' interventions is not undisputable. This article briefly summarizes the evidence about perpetrators' intervention efficacy, factors associated with recidivism, and evidence-based recommendations, before outlining the assumptions of a new community-delivered intervention aiming to rehabilitate IPV perpetrators: the CONTIGO Program. This program uses an innovative framework, focused on early maladaptive schemas, and combining cognitive, interpersonal, and motivational interview principles. The features of this intervention are discussed, and exploratory results regarding drop-out rates (8%) and recidivism (15.4%) in a sample of 162 court-mandated males are exposed. The detailed presentation of the CONTIGO Program and its intervention model represents a novel contribution that is sorely lacking in the IPV literature and could foster further research and debate about what can be done to effectively intervene with IPV perpetrators.

Examining implementation of an intervention to reduce psychological distress and intimate partner violence in a refugee camp setting

An integrated approach to reduce intimate partner violence and improve mental health in humanitarian settings requires coordination across health and protection services. We developed and tested the Nguvu intervention, which combined evidence-based interventions for psychological distress and intimate partner violence among Congolese refugee women in Nyarugusu refugee camp (Tanzania). We conducted 29 semi-structured interviews with Nguvu participants and stakeholders to explore the relevance, acceptability, feasibility, and impact of this intervention. Participants reported that the intervention aligned with needs and filled a gap in programming, yet further adaptations may improve the fit of the intervention. The Nguvu intervention was acceptable to participants, including group discussion of sensitive topics. Confidentiality was highly regarded among staff and participants, which improved safety and acceptability. It was feasible to train non-specialist refugee workers to deliver the intervention with adequate supervision. Facilitators noted contextual challenges that made it difficult to implement the intervention: limited infrastructure, competing priorities, and population mobility. The intervention was perceived to improve awareness of the association between violence and mental health, reduce self-blame, and build skills to improve wellbeing. Recommended adaptations reveal promising, yet challenging future directions for addressing social determinants of mental health and implementing multi-sectoral programmes in complex humanitarian settings.

PTSD and Depression Symptoms Increase Women's Risk for Experiencing Future Intimate Partner Violence

Psychological distress may impact women's risk for future intimate partner violence (IPV). Yet, limited research has utilized longitudinal research designs and there is a scarcity of research looking at the three most commonly implicated mental health factors-posttraumatic stress disorder (PTSD), depression, and alcohol use-within the same study. Research is especially scarce for women veterans, who experience substantial risk for these mental health concerns and experiencing IPV. This study examined the role of PTSD symptoms, depression symptoms, and alcohol use in increasing risk for experiencing future IPV while simultaneously accounting for the impact of recent IPV experience on subsequent mental health. This study included a sample of 1921 women veterans (M_age = 36.5), who were asked to complete three mail surveys over the course of 8 months as part of a larger longitudinal survey study of US veterans' health and well-being. The survey assessed experiences of IPV, PTSD symptoms (PCL-5), depression symptoms (PHQ-9), and alcohol use (AUDIT-C) at each of the three time points. Results from separate path analysis models provided support for the role of PTSD symptoms and depression symptoms (but not alcohol use) in increasing risk for IPV experience over time. However, the path analysis models provided little support, with the exception of PTSD, for the impact of IPV experience on subsequent mental health symptoms. Findings point to the importance of better understanding the mechanisms by which PTSD and depression symptoms can increase risk for IPV to inform theory and prevention and treatment efforts. Detection and treatment of PTSD and depression symptoms among women may help reduce risk for future violence in intimate relationships.

Prosecutorial decision-making regarding offenders’ social reintegration programs in intimate partner violence cases. A Portuguese study

Intimate partner violence is one of the most challenging and demanding problems that the criminal justice system has to face. Given the severe consequences of intimate partner violence, it is imperative that intervention from the criminal justice system, regarding perpetrators, be effective to prevent further victimization and recurrences. In Portugal, it is up to the state prosecutor to decide which cases will be subject to a social reintegration program as a pretrial diversion program. This study aims to explore the variables that might influence the state prosecutor’s decision-making process. We have examined 283 intimate partner violence cases in which provisional suspension of criminal proceedings was applied. The decision as to whether defendants should be referred for social reintegration program attendance (G1) or not (G2) was made by the state prosecutor. Differences between G1 and G2 were identified: the victim’s age, couple living in a current relationship, drug-addicted defendant, intimate partner violence child exposure. However, defendants’ unemployment and drug abuse were the only two variables identified as a determinant for state prosecutor decisions. We believe that the effectiveness of state prosecution decision-making would benefit from: (a) systematically taking into account all intimate partner violence risk factors; (b) an index or checklist detailing what science reveals useful in intimate partner violence offenders’ social reintegration; (c) rehabilitation solutions based on the needs of each offender instead of a “one-size-fits-all” approach.

Predictors of the Sense of Embodiment of a Female Victim of Sexual Harassment in a Male Sample Through 360-Degree Video-Based Virtual Reality

The sense of embodiment refers to the set of sensations related to having (i.e., ownership), being located in (i.e., location), and controlling (i.e., agency) a virtual body. Recently, 360-degree video-based Virtual Reality (VR) has been used to manipulate the sense of embodiment, generating the body-swap illusion, that is, the illusionary switch from the real body to a virtual one. However, the psychological mechanisms involved in this illusion are still unknown. The present study is a secondary analysis of the study by Ventura et al. (2021) investigating the feasibility of 360-degree video to induce the body swap from a male's real body to a female virtual body in a sexual harassment virtual environment. In addition, the study explores whether the sense of presence and psychological trait variables related to sexual harassment (i.e., machismo, chivalry, alexithymia, empathic abilities) predict the illusion of owning the body of a female victim of sexual harassment. Forty-four men participated in the study, and the results indicate that the 360-degree video is able to induce the body-swap illusion for location and ownership, but not for agency. Multiple regression analyses showed that the sense of presence was a predictor of the three dimensions of embodiment, but specific psychological traits (i.e., low scores on machismo, high scores on difficulties expressing feelings, and high scores on perspective taking) were also predictor variables of experiencing a greater sense of location and agency in the female virtual body. This study shows that both technological issues and participants' psychological traits are involved in the experience of the body-swap illusion in a sexual harassment scenario using 360-degree video-based VR.

Treatment for perpetrators of intimate partner violence: What is the evidence?

Intimate partner violence (IPV) is recognized as a worldwide health issue that calls for urgent interventions to prevent the significant physical and mental harm it poses to the individuals involved and to reduce its wider deleterious impacts on society. Despite 40 years of research in the field, incidence rates of IPV have not significantly declined and treatment services for perpetrators of IPV are scarce. Empirical research has been hindered by ideological disputes, and the most commonly used treatment approaches-the feminist-oriented Duluth approach and cognitive-behavioral treatments-lack evidence for their efficacy. This introduction to this issue of In Session reviews these ideological controversies and the current state of empirical evidence for the treatment of perpetrators of IPV; and summarizes the five papers, commissioned from different countries in Europe, North America, and Africa, comprising this issue, each of which presents a novel therapeutic intervention for this heterogeneous population.
