Project description:People sometimes hurt those they profess to love; yet our understanding of intimate partner aggression (IPA) and its causes remains incomplete. We examined brain activity using functional magnetic resonance imaging (fMRI) in an ethnically and racially diverse sample of 50 female-male, monogamous romantic couples as they completed an aggression task against their intimate partner, a close friend, and a different-sex stranger. Laboratory and real-world IPA were uniquely associated with altered activity within and connectivity between cortical midline structures that subserve social cognition and the computation of value. Men's IPA most corresponded to lower posterior cingulate reactivity during provocation and women's IPA most corresponded to lower ventromedial prefrontal cortex activity during IPA itself. Actor-partner independence modeling suggested women's IPA may correspond to their male partner's neural reactivity to provocation. Broadly, these findings highlight the importance of self-regulatory functions of the medial cortex and away from effortful inhibition subserved by dorsolateral cortices.

Project description:The attachment theory has commonly been used to examine intimate partner psychological aggression (IPPA), but few studies have examined its association with self-reported justifications for one's own use of IPPA. Behaviors, including the use of IPPA, are influenced, maintained, and function within the context of their justifications, highlighting the importance of investigating these justifications to obtain a clearer picture of IPPA. This study examined whether insecure romantic attachment (i.e., attachment anxiety and attachment avoidance) in both partners of a couple was associated with their justifications for their own use of IPPA. A community sample of 81 mixed-sex couples who reported using IPPA in the last year completed self-reported questionnaires on adult romantic attachment and their justifications for their use of IPPA. Results of a path analysis based on the actor-partner interdependence model revealed moderate positive associations between attachment anxiety and one's use of internal and external justifications for their IPPA perpetration in men and women. An unexpected dyadic positive association is discussed. These results suggest that the use of justifications for one's use of IPPA may reflect a strategy of hyperactivation that could contribute to the cycle of psychological aggression. Uncovering the function of these justifications could provide important therapeutic benefits, which are discussed in the study's implications.

Project description:Qualitative evidence suggests that husbands' inequitable gender equity (GE) ideologies may influence associations between husbands' alcohol use and intimate partner violence (IPV) against wives. However, little quantitative research exists on the subject. To address this gap in the literature, associations of husbands' elevated alcohol use and GE ideologies with wives' reports of IPV victimization among a sample of married couples in Maharashtra, India, were examined. Cross-sectional analyses were conducted using data from the baseline sample of the Counseling Husbands to Achieve Reproductive Health and Marital Equity (CHARM) study. Participants included couples aged 18 to 30 years ( N = 1081). Regression models assessed the relationship between husbands' elevated alcohol use and GE ideologies (using the Gender-Equitable Men [GEM] Scale) and wives' history of physical and/or sexual IPV victimization ever in marriage. Husbands and wives were 18 to 30 years of age, and married on average of 3.9 years ( SD ± 2.7). Few husbands (4.6%) reported elevated alcohol use. Husbands had mean GEM scores of 47.3 ( SD ± 5.4, range: 35-67 out of possible range of 24-72; least equitable to most equitable). Approximately one fifth (22.3%) of wives reported a history of physical and/or sexual IPV. Wives were less likely to report IPV if husbands reported greater GE ideologies (adjusted odds ratio [AOR]: 0.97, 95% CI [0.95, 0.99]), and husband's elevated alcohol use was associated with increased risk of IPV in the final adjusted model (AOR: 1.89, 95% CI [1.01, 3.40]). Findings from this study indicate the need for male participation in violence intervention and prevention services and, specifically, the need to integrate counseling on alcohol use and GE into such programming.

Project description:Decades of research has identified alcohol use as a contributing cause of intimate partner aggression (IPA) perpetration; however, there have been fewer studies that seek to identify mediators of the relation between alcohol use and IPA perpetration. Building on research showing a positive association between problematic drinking and relationship dissatisfaction and relationship dissatisfaction and IPA, we examined whether relationship dissatisfaction accounted for the relation between problematic drinking and IPA perpetration in couples using statistical modeling that accounted for the interdependence between partners. Our results showed that (a) actor problematic drinking was related to actor psychological and physical IPA perpetration and that this relation was partially explained by actor relationship dissatisfaction, (b) partner problematic drinking was related to actor physical and psychological IPA perpetration and that this relation was partially explained by actor relationship dissatisfaction, and (c) partner problematic drinking was related to actor psychological IPA perpetration and that this relation was partially explained by partner relationship dissatisfaction. Together, our results highlight that when partner interdependence is considered, relationship dissatisfaction could be a potential mechanism of the alcohol-IPA association and provide some evidence for different pathways for psychological and physical aggression.

Project description:BackgroundAlthough intimate partner sexual aggression has been shown to be associated with adverse mental health outcomes, there is scant information about sexual aggression in Chinese intimate relationships in general and about its mental health impact in particular. This article aimed to investigate sexual aggression in Chinese intimate relationships, including the use of force or threat of force and non-physical coercive tactics in unwanted sex.MethodsThe quantitative and qualitative data used in this paper were drawn from a prospective cohort study conducted in Hong Kong between September 2010 and September 2012. A total of 745 Chinese women aged 18 or older who had been in an intimate relationship in the preceding 12 months were recruited from sites in all districts of Hong Kong. Multiple logistic regression analysis, ordinary linear regression, and t-tests were used in quantitative analysis. Directed content analysis was used to analyze the transcripts of 59 women who revealed experiences of intimate partner sexual aggression in individual in-depth interviews.ResultsOf the 745 Chinese women in the study, 348 (46.7%) had experienced intimate partner physical violence in the past year, and 179 (24%) had experienced intimate partner physical violence and sexual aggression in the past year. Intimate partner sexual aggression significantly predicted PTSD and depressive symptoms after controlling for intimate partner physical violence. Among the 179 women reporting intimate partner physical violence and sexual coercion in the past year, 75 indicated that their partners used force or threat of force to make them have sex, and 104 of them reported that they gave in to sex because of non-physical coercive tactics used by their partners. Qualitative data revealed a variety of non-physical coercive tactics with different degrees of subtlety used to coerce women into unwanted sex with their partners. Chinese women experiencing physically forced sex had significantly more depressive symptoms and PTSD symptoms.ConclusionsOur findings indicate that sexual aggression in Chinese intimate relationships has specific mental health consequences over and above those associated with physical violence. Assessment of partner violence in Chinese relationships should include screening for sexual aggression in order to provide appropriate interventions.Trial registrationClinicalTrials gov NCT01206192.

Project description:BackgroundIntimate partner violence (IPV) is a significant public health issue that affects 1 in 3 women globally and a similarly large number of women in Nepal. Over the past decade, important policy and programmatic steps have been taken to address violence against women in Nepal. There remains a dearth of evidence on the effectiveness of primary violence prevention strategies. The Change Starts at Home study begins to fill this gap by utilizing a multi-component social behaviour change communication (SBCC) strategy involving a radio drama and community mobilization to shift attitudes, norms and behaviours that underpin IPV perpetration in Nepal.Methods/designThe study uses a concurrent mixed-methods design. The quantitative aspect of the evaluation is a pair-matched, repeated cross-sectional 2-armed, single-blinded cluster trial (RCT: N = 36 clusters, 1440 individuals), comparing a social behaviour change communication (SBCC) strategy to radio programming alone for its impact on physical and / or sexual IPV at the end of programming (12 months' post-baseline) and 6-months post the cessation of project activities (18-months post baseline). The qualitative aspects of the design include several longitudinal approaches to understand the impact of the intervention and to examine mechanisms of change including in-depth interviews with participants (N = 18 couples), and focus group discussions with community leaders (N = 3 groups), and family members of participants (N = 12 groups). Treatment effects will be estimated with generalized logistic mixed models specified to compare differences in primary outcome from baseline to 12-month follow-up, and baseline to 18-months follow-up in accordance with intention-to-treat principles.DiscussionThe study rigorously evaluates the effectiveness of a promising strategy to prevent IPV. The results of the trial will be immediately useful for governmental, nongovernmental, and donor funded programs targeting partner violence or social norms that underpin it. Findings of the study will also contribute to global knowledge on the effectiveness of media and community engagement as a primary prevention strategy for IPV.Trial registrationTrial was registered in clinicaltrials.gov, NCT02942433 , 10/13/2016, retrospectively registered.

Project description:BACKGROUND:Hazardous alcohol use is a predictor of intimate partner violence (IPV), and both are increasingly prevalent in sub-Saharan Africa. The accurate measurement of alcohol consumption is therefore critical in IPV intervention studies that target hazardous drinking. Collecting a collateral report in addition to self-report is one convergent validity approach to improve alcohol measurement. We investigated concordance between self- and partner-reported alcohol use among women who reported recent IPV and their male partners in Zambia. METHODS:Data were from the baseline of a randomized IPV intervention trial of 247 heterosexual couples in which a woman has reported recent IPV and her male partner has recent hazardous alcohol use. Both partners completed the Alcohol Use Disorders Identification Test (AUDIT) in reference to their own drinking and in reference to their partner's drinking. We calculated percent agreement across a range of outcomes: any use, quantity, frequency, and hazardous use. We also compared self- and partner-reported AUDIT scores using t-tests. RESULTS:Concordance was poor across most outcomes. Percent agreement with respect to the women's drinking ranged from 60% to 65% across outcomes and with respect to the men's drinking from 51% to 89%. Women's average partner-reported AUDIT score (20.7) was statistically significantly (p < 0.0001) higher than men's average self-reported score (15.8). CONCLUSIONS:In contrast to collateral report studies conducted in the United States, concordance between self- and partner-reported alcohol consumption was poor among families experiencing IPV in Zambia. Given the possible biases associated with self-reported alcohol use, findings suggest that a convergent validity approach is useful in this research context.

Project description:Intimate partner violence (IPV) among male couples is increasingly recognized as a public health concern. Research on IPV in opposite sex couples indicates frequent underreporting of IPV and high levels of discordance in reporting among dyads. Concordance studies inform refinement methods to measure the experience of IPV among dyads; however the lack of dyadic studies of male couples impedes our understanding of the extent to which IPV is differentially reported in male-male dyads. This study utilized baseline data from a randomized controlled trial of a behavioral intervention to optimize antiretroviral therapy (ART) adherence among 160 sero-discordant male couples in three US cities and provides the first analysis of concordance in reporting IPV among male couples. Low degrees of concordance in the reporting of IPV were identified among male dyads, with a greater proportion of men reporting violence perpetration than experiencing violence. The greater reporting of IPV perpetration may be linked to adherence to concepts of masculinity. The results underscore the unique experiences of IPV among male couples and the need to reexamine current IPV measurement and intervention strategies.

Project description:In recent years, major global institutions have amplified their efforts to address intimate partner violence (IPV) against women-a global health and human rights violation affecting 15-71% of reproductive aged women over their lifetimes. Still, some scholars remain concerned about the validity of instruments used for IPV assessment in population-based studies. In this paper, we conducted two validation analyses using novel data from 450 women-men dyads across nine villages in Northern Tanzania. First, we examined the level of inter-partner agreement in reporting of men's physical, sexual, emotional and economic IPV against women in the last three and twelve months prior to the survey, ever in the relationship, and during pregnancy. Second, we conducted a convergent validity analysis to compare the relative efficacy of men's self-reports of perpetration and women's of victimization as a valid indicator of IPV against Tanzanian women using logistic regression models with village-level clustered errors. We found that, for every violence type across the recall periods of the last three months, the last twelve months and ever in the relationship, at least one in three couples disagreed about IPV occurrences in the relationship. Couples' agreement about physical, sexual and economic IPV during pregnancy was high with 86-93% of couples reporting concordantly. Also, men's self-reported perpetration had statistically significant associations with at least as many validated risk factors as had women's self-reported victimization. This finding suggests that men's self-reports are at least as valid as women's as an indicator of IPV against women in Northern Tanzania. We recommend more validation studies are conducted in low-income countries, and that data on relationship factors affecting IPV reports and reporting are made available along with data on IPV occurrences.

Project description:BackgroundRisk factors of violence perpetration in veterans include substance use and posttraumatic stress disorder (PTSD); however, it is unknown whether these factors are associated with greater risk for partner or non-partner violence. This study investigated the associations between probable PTSD, heavy drinking, marijuana use, cocaine use, and partner and non-partner violence perpetration.MethodsSelf-report questionnaires assessing past-year partner and non-partner aggression (CTS2) as well as past-month substance use (SAOM), probable PTSD (PCL-C), and probable depression (PHQ-9) were administered to 810 substance using veterans entering VA mental health treatment.ResultsIn bivariate analyses, probable PTSD in substance using veterans was associated with violence perpetration (partner physical, χ2=11.46, p=0.001, φ=0.12; non-partner physical, χ2=50.64, p<0.001, φ=0.25; partner injury, χ2=6.41, p=0.011, φ=0.09; non-partner injury, χ2=42.71, p<0.001, φ=0.23). In multiple logistic regression analyses that adjusted for sociodemographic characteristics, probable PTSD was independently associated with non-partner physical (odds ratio [OR], 2.82; 95% confidence interval [CI], 1.97-4.05) and injury aggression (OR, 3.96; CI, 2.56-6.13). Cocaine and heavy drinking were independently associated with non-partner physical and injury aggression and non-partner injury aggression respectively.ConclusionsThe results provide evidence that probable PTSD, heavy drinking, and cocaine use are associated with increased risk of non-partner violence perpetration in substance using veterans. These results underscore the importance of screening for PTSD symptoms and violence perpetration towards non-partners in substance using veterans presenting for treatment.
