Project description:Despite evidence that genetic variation contributes to aggression, few studies have examined how genetic variation contributes to IPA specifically. In the current study, 69 couples from a Midwestern university completed self-report measures of IPA, childhood trauma exposure, and hazardous alcohol use, and were randomly assigned to consume either a placebo or alcohol beverage before participating in an analogue aggression task against their partner. Genetic risk (i.e., association with lower transcriptional efficiency) for aggression was measured with a polygenic risk score (PRS) created from four polymorphisms (HTR1B rs13212041, HTR2B rs6437000, 5-HTTLPR, and MAOA uVNTR). Among individuals with a low PRS, individuals who consumed alcohol (BrAC = 0.07%) showed greater unprovoked IPA than individuals who consumed a placebo. Findings contribute to our limited understanding regarding the etiology of IPA and suggest that individuals who have increased transcriptional activity in certain serotonin system genes may be at higher risk of IPA when intoxicated.

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:Longitudinal research supports that suicidal thoughts and behaviors in adolescence predict maladjustment in young adulthood. Prior research supports links between suicide attempt and aggression, perhaps because of a propensity for impulsive behavior in states of high negative affect that underlies both problems. Such vulnerability may increase risk for intimate partner violence and generally poor young adulthood relational adjustment.A total of 153 men participated in annual assessments from ages 10-32 years and with a romantic partner at three assessments from ages 18-25 years. Multi-method/multi-informant constructs were formed for parent/family risk factors, adolescent psychopathology (e.g. suicide-attempt history, mother-, father-, teacher- and self-reported physical aggression) and young adulthood relational distress (jealousy and low relationship satisfaction) and maladaptive relationship behavior (observed, self- and partner-reported physical and psychological aggression toward a partner, partner-reported injury, official domestic violence arrest records and relationship instability).Across informants, adolescent aggression was correlated with suicide-attempt history. With few exceptions, aggression and a suicide attempt in adolescence each predicted negative romantic relationship outcomes after controlling for measured confounds. Adolescent aggression predicted young adulthood aggression toward a partner, in part, via relationship dissatisfaction.Boys' aggression and suicide-attempt history in adolescence each predict poor relationship outcomes, including partner violence, in young adulthood. Findings are consistent with the theory of a trait-like vulnerability, such as impulsive aggression, that undermines adaptation across multiple domains in adolescence and young adulthood. Prevention and intervention approaches can target common causes of diverse public health problems.

Project description:BackgroundIntimate 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.MethodsEleven 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.ResultsPopulation-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.ConclusionsDespite 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.

Project description:BACKGROUND:Preconceptual prevention programs geared toward reducing alcohol-exposed pregnancy (AEP) typically emphasize behavioral change of alcohol use and birth control exclusively, but rarely consider other important AEP predictors that may affect behavioral change. Intimate partner violence (IPV) substantially relates to AEP and to AEP predictors; however, few studies have tested if IPV is a unique indicator of prospective AEP risk, as both a main effect and a contextual influence on alcohol use or birth control. METHODS:Using Waves II and III of the National Longitudinal Study of Adolescent to Adult Health, multilevel logistic regression models were estimated, in which IPV and birth control (both within-person and between-person) and adolescent alcohol use (between-person only) were examined as unique predictors of AEP compared to both nonpregnancy and non-AEP (nAEP) outcomes over up to 5 sexual relationships. Interactions between within-person and between-person IPV, and birth control or alcohol use were also tested. RESULTS:Within-person and between-person IPV significantly related to higher odds of AEP compared to nonpregnancy and nAEP. Adolescent alcohol use had similarly increased odds for AEP when compared to nonpregnancy or nAEP outcomes. Only between-person birth control use related to higher odds for AEP compared to nonpregnancy and nAEP. Between-person IPV also moderated adolescent alcohol use on odds of AEP, such that infrequent adolescent drinkers had higher odds of AEP compared to nonpregnancy or nAEP if they experienced IPV over their relationships. CONCLUSIONS:IPV is a substantial predictor for AEP as both a direct influence within relationships (within-person) and between individuals (between-person). Intervention and prevention programs focused on reducing AEP may benefit from including IPV-specific curricula.

Project description:INTRODUCTION:Intimate partner violence (IPV) results in deaths of both primary and corollary (i.e., nonintimate partner) victims. Alcohol use is a known risk factor for IPV, yet the relationship between alcohol policies and IPV homicides is unclear. This repeated cross-sectional study characterizes alcohol involvement, and the relationship between alcohol policies and alcohol involvement, among victims of IPV homicides in the U.S. METHODS:Homicide victim data from 17 states in the National Violent Death Reporting System from 2003 to 2012 were analyzed in 2017-2018. Alcohol Policy Scale scores characterized alcohol policies by state year and were used in generalized estimating equation logistic regression models to predict the odds of alcohol involvement among victims of IPV homicide. RESULTS:Among victims of IPV homicide, 36.5% of primary and 41.1% of corollary victims had a blood alcohol concentration (BAC) >0.00%. Of the victims with a positive BAC, 67.6% had a BAC ?0.08%. In adjusted models, a 10-percentage point increase in Alcohol Policy Scale score was associated with reduced odds of having a positive BAC (AOR=0.77, 95% CI=0.64, 0.93) and having a BAC ?0.08% (AOR=0.82, 95% CI=0.68, 0.99) among all victims, primary victims (AOR=0.78, 95% CI=0.63, 0.98; AOR=0.82, 95% CI=0.65, 1.04), and corollary victims (AOR=0.61, 95% CI=0.42, 0.89; AOR=0.68, 95% CI=0.48, 0.97). CONCLUSIONS:Alcohol use was prevalent among victims of IPV homicide, and more-restrictive alcohol policies were associated with reduced odds of alcohol involvement. Strengthening alcohol policies is a promising strategy to reduce alcohol-involved IPV homicide victimization.

Project description:BACKGROUND:Risk 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. METHODS:Self-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. RESULTS:In bivariate analyses, probable PTSD in substance using veterans was associated with violence perpetration (partner physical, ?2=11.46, p=0.001, ?=0.12; non-partner physical, ?2=50.64, p<0.001, ?=0.25; partner injury, ?2=6.41, p=0.011, ?=0.09; non-partner injury, ?2=42.71, p<0.001, ?=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. CONCLUSIONS:The 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.

Project description:Intimate partner aggression (IPA) is a significant public health burden, and thus efforts to identify individual characteristics that predict perpetration of IPA is an important research question. Personality disorders are a significant correlate of IPA, both cross-sectionally and longitudinally. Much of that work, however, had been conducted in younger samples. IPA in older adults is a relatively understudied area of research generally. Thus, examining the association between personality pathology and IPA in older adults is novel and important. In previous work using the St. Louis Personality and Aging Network sample, we found that borderline personality disorder was a robust correlate of perpetrating partner aggression in older, romantically involved participants. In the current analyses, we attempted to replicate our original findings in the same sample assessed 2.5 years later. We also extended the original work by using both self- and partner-reported IPA and by using latent factors of personality pathology. We found that prevalence of IPA in this sample was similar to the baseline assessment; 69.1% reported IPA in the past year, with the vast majority being psychological/verbal rather than physical aggression. Agreement between partners on perpetration was modest. Borderline personality pathology was again the strongest and most consistent predictor of IPA. Our findings speak to the continuing public health burden of borderline personality pathology into older age as evidenced by associations with perpetration of IPA.

Project description:ImportanceIntimate partner violence (IPV) is an important cause of death and disability worldwide. The literature estimates that 45% of IPV injuries involve the eyes. Many medical fields have increased IPV-related research; however, ophthalmology IPV research remains rare.ObjectiveTo evaluate the epidemiologic pattern and injury mechanism of IPV related to ocular trauma.Design, setting, and participantsThis study was a retrospective cross-sectional analysis with deidentified data using the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Clinical Modification (ICD-10-CM) codes from the National Trauma Data Bank (NTDB), which is a data set collected by the American College of Surgeons. The NTDB is the largest US hospitalized trauma case database with submissions from more than 900 US facilities. Included in this analysis were the IPV-related ocular injuries of patients hospitalized between 2017 and 2019. Study data were analyzed from April 20 to October 15, 2022.ExposuresIPV-related ocular injuries.Main outcomes and measuresOcular injuries and adult IPV trauma survivors were identified with the ICD-10-CM codes. The following demographic data were collected: sex, age, race and ethnicity, health insurance plan, substance misuse screening results, trauma level of hospital, the emergency department disposition, the total Glasgow Coma Scale score, the abbreviated injury scale, and caregiver at discharge.ResultsA total of 2598 of the recorded ocular injuries were associated with IPV. Patients had a mean (SD) age of 45.2 (18.4) years, and 1618 were female (62.3%). Most patients in the population sample (1195 [46.0%]) were aged 18 to 39 years. The race and ethnicity distribution was as follows: 629 Black (24.2%), 296 Hispanic (11.4%), 1358 White (52.3%), 229 other (8.8%), and 86 missing (3.3%). Insurance statuses were Medicaid (847 [32.6%]), Medicare (524 [20.2%]), private insurance (524 [20.2%]), and self-pay (488 [18.8%]). Women had greater odds of testing positive during alcohol screening (odds ratio [OR], 1.42; 95% CI, 1.21-1.67; P < .001). Black patients were most likely to have Medicaid (OR, 1.64; 95% CI, 1.35-1.99; P < .001), Hispanic patients were most likely to self-pay (OR, 1.96, 95% CI, 1.48-2.58; P < .001), and White patients were most likely to use Medicare (OR, 2.94, 95% CI, 2.33-3.73; P < .001).Conclusions and relevanceSocial determinants of health were identified as key risk factors for IPV-related ocular injuries. Study findings highlight identifiable risk factors associated with IPV and ocular trauma that can contribute to IPV awareness among ophthalmologists.

Project description:Deficits in executive functioning have been associated with aggressive and violent behavior toward intimate partners. However, it is unclear what specific mechanisms are being affected by cognitive deficits that increase an individual's tendency to become aggressive. The current study examined empathy as a mediating factor between deficits in working memory and perpetration of intimate partner aggression and violence. Men in heterosexual relationships (N = 49) were administered a measure of visual-spatial working memory, and questionnaire measures of head injury and empathy. During a second session, men participated in a conflict discussion with their female partner that was coded for aggressive behavior. Female partners also reported on men's physical and psychological abuse. Working memory was positively related to cognitive and affective empathy, and negatively related to men's physical abuse perpetration and observed aggression during the conflict discussion. The effects of working memory on observed aggression during the conflict were fully mediated by cognitive and affective empathy. Additionally, the effects of working memory on reported physical IPV frequency were fully mediated by affective empathy. Deficits in working memory may decrease men's ability to use empathetic processes, resulting in increased aggression and violence toward their intimate partners. Clinically, incorporating empathy training in battering intervention programs may be helpful, especially among men with deficits in cognitive functioning.
