Alcohol outlet density, drinking contexts and intimate partner violence: a review of environmental risk factors

Emotion differentiation and intimate partner violence: Effects of provocation and alcohol intoxication

OBJECTIVE

This study investigated the impact of relational provocation on intimate partner violence (IPV) perpetration as a function of alcohol intoxication and individuals' emotion differentiation (ED; i.e., the ability to differentiate between positive and negative emotions). We hypothesized that provocation and acute intoxication would be associated with lower ED, such that individuals would demonstrate lower ED following provocation and while intoxicated. We also hypothesized an intoxication-by-ED interaction, such that only individuals who were intoxicated and undifferentiated would perpetrate IPV.

METHOD

Two hundred fifty community-based adults completed an aggression paradigm ostensibly with their romantic partners where they were randomly assigned to an alcohol or no-alcohol condition. Participants' ED across positive and negative subscales was calculated at baseline (Time 1), postprovocation and intoxication (Time 2), and postbehavioral aggression (Time 3). IPV was operationalized as the strength and duration of shocks issued to their partner during the aggression paradigm.

RESULTS

Both sober and intoxicated participants experienced lower ED following provocation, suggesting a main effect of provocation but no main effect of intoxication. There was a significant alcohol-by-ED interaction in the predicted direction. For intoxicated participants, low ED was associated with greater IPV perpetration. For sober participants, low ED was associated with less IPV perpetration.

CONCLUSIONS

Consistent with hypotheses, low ED is associated with greater IPV perpetration among intoxicated individuals. In contrast to prior research, low ED was associated with less IPV perpetration among sober individuals. Alcohol-related cognitive impairments may increase the likelihood of IPV perpetration by disrupting the ED process that may otherwise inhibit impulsive aggression.

An Exploration of Geographic Access to Substance Use Treatment Programs and Violence Against Women

Violence against women (VAW) is a significant public health and human rights issue, with an estimated 736 million women globally experiencing VAW. Consistent evidence demonstrates that substance use is associated with VAW and that participation in substance use treatment programs is associated with reduction in substance use-related violence. While evidence demonstrates the ability to address VAW through substance use treatment programs, less attention has been paid to geographic access to substance use programs. If these programs are geographically inaccessible, particularly to marginalized populations, many people will not get the help they need. This study seeks to explore the relationship between geographic access to substance use treatment programs on VAW. Using data from the HIV Prevention Trials Network (HPTN) 064 study, longitudinal multilevel models were used to assess the relationship between neighborhood-level social determinants, with a specific focus on geographic access to Substance Abuse and Mental Health Services Administration (SAMHSA) certified drug and alcohol treatment programs and VAW. The study included 1910 women, ages 18 to 44, living in select geographic areas with high-ranked prevalence of HIV and poverty. The findings of this study indicate that among women who reside in census tracts with high prevalence rates of HIV: (1) substance use increases VAW; (2) VAW decreases as geographic access to SAMHSA-certified drug and alcohol treatment facilities increases; and (3) when looking at specific types of VAW, emotional and physical abuse decreases as geographic access to substance use treatment increases. Policies and programs to increase access to substance use treatment should be explored and evaluated, and more programs are needed that address the intersectionality of substance use and VAW.

Community-Level Risk Factors for Firearm Assault and Homicide: The Role of Local Firearm Dealers and Alcohol Outlets

BACKGROUND

Identifying community characteristics associated with firearm assault could facilitate prevention. We investigated the effect of community firearm dealer and alcohol outlet densities on individual risk of firearm assault injury.

METHODS

In this density-sampled case-control study of Californians, January 2005-September 2015, cases comprised all residents with a fatal or nonfatal firearm assault injury. For each month, we sampled controls from the state population in a 4:1 ratio with cases. Exposures were monthly densities of county-level pawn and nonpawn firearm dealers and ZIP code-level off-premises alcohol outlets and bars and pubs ("bars/pubs"). We used case-control-weighted G-computation to estimate risk differences (RD) statewide and among younger Black men, comparing observed exposure densities to hypothetical interventions setting these densities to low. We estimated additive interactions between firearm and alcohol retailer density. Secondary analyses examined interventions targeted to high exposure density or outcome burden areas.

RESULTS

There were 67,850 cases and 268,122 controls. Observed (vs. low) densities of pawn firearm dealers and off-premises alcohol outlets were individually associated with elevated monthly risk of firearm assault per 100,000 people (RD pawn dealers : 0.06, 95% CI: 0.05, 0.08; RD off-premises outlets : 0.01, 95% CI: 0.01, 0.03), but nonpawn firearm dealer and bar/pub density were not; models targeting only areas with the highest outcome burden were similar. Among younger Black men, estimates were larger. There was no interaction between firearm and alcohol retailer density.

CONCLUSIONS

Our results are consistent with the hypothesis that limiting pawn firearm dealers and off-premises alcohol outlet densities can reduce interpersonal firearm violence.

Epidemiologic Pattern and Injury Mechanism of Intimate Partner Violence-Related Ocular Trauma in the US

Importance

Intimate 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.

Objective

To evaluate the epidemiologic pattern and injury mechanism of IPV related to ocular trauma.

Design, Setting, and Participants

This 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.

Exposures

IPV-related ocular injuries.

Main Outcomes and Measures

Ocular 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.

Results

A 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 Relevance

Social 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.

Problem Drinking is Associated with Intimate Partner Cyber Abuse Perpetration but is Buffered by High Relationship Satisfaction

Purpose

Intimate partner cyber abuse (IPCA) is a prevalent form of intimate partner violence (IPV) that has detrimental effects on victims' well-being. Although research has documented associations with other forms of IPV perpetration, additional research is needed to identify IPCA perpetration risk factors. One of the most common risk factors for offline IPV is perpetrators' alcohol use; however, less is known about how this translates to online contexts. There is also a need to identify protective factors that mitigate the effects of alcohol.

Methods

This study evaluated associations between drinking, relationship satisfaction, and IPCA perpetration via self-report questionnaires within a longitudinal framework. Participants included 544 adults in an intimate relationship (n = 296 at T2).

Results

Results indicated that relationship satisfaction buffered the effects of problem drinking on IPCA perpetration at T1, but not at T2. Further, 20.2% of individuals who perpetrated IPCA at T1 drank alcohol during at least one incident, and these individuals reported more problem drinking and more frequent IPCA perpetration compared to those who reported IPCA without alcohol.

Conclusion

Results from this study provide insight into both risk and protective factors for IPCA perpetration among adults and have the potential to guide concurrent prevention strategies that target intersections between problem drinking, IPCA, and offline IPV, and promote healthy and satisfying intimate relationships.

The role of alcohol outlet visits derived from mobile phone location data in enhancing domestic violence prediction at the neighborhood level

Domestic violence (DV) is a serious public health issue, with 1 in 3 women and 1 in 4 men experiencing some form of partner-related violence every year. Existing research has shown a strong association between alcohol use and DV at the individual level. Accordingly, alcohol use could also be a predictor for DV at the neighborhood level, helping identify the neighborhoods where DV is more likely to happen. However, it is difficult and costly to collect data that can represent neighborhood-level alcohol use especially for a large geographic area. In this study, we propose to derive information about the alcohol outlet visits of the residents of different neighborhoods from anonymized mobile phone location data, and investigate whether the derived visits can help better predict DV at the neighborhood level. We use mobile phone data from the company SafeGraph, which is freely available to researchers and which contains information about how people visit various points-of-interest including alcohol outlets. In such data, a visit to an alcohol outlet is identified based on the GPS point location of the mobile phone and the building footprint (a polygon) of the alcohol outlet. We present our method for deriving neighborhood-level alcohol outlet visits, and experiment with four different statistical and machine learning models to investigate the role of the derived visits in enhancing DV prediction based on an empirical dataset about DV in Chicago. Our results reveal the effectiveness of the derived alcohol outlets visits in helping identify neighborhoods that are more likely to suffer from DV, and can inform policies related to DV intervention and alcohol outlet licensing.

Evaluating the effects of two alcohol reduction counseling interventions on intimate partner violence perpetration: secondary analysis of a three-arm randomized controlled trial among Vietnamese men with HIV

BACKGROUND AND AIMS

Evidence suggests that alcohol reduction interventions decrease intimate partner violence (IPV) perpetration, although this remains untested in low- and middle-income countries and among men with human immunodeficiency virus (HIV). This study evaluates the effectiveness of alcohol reduction counseling interventions on IPV perpetration among men on anti-retroviral therapy (ART) and tests whether alcohol use explains the intervention effects.

DESIGN

Secondary analysis of data from a three-arm randomized controlled trial among ART patients with hazardous alcohol use. Participants were recruited from March 2016 to May 2017.

SETTING

Thai Nguyen, Vietnam.

PARTICIPANTS, INTERVENTIONS AND COMPARATORS

Male participants (n = 426). Participants received a two-session brief intervention (BI), a six-session combined intervention (CoI) or the standard of care (SOC), comprising alcohol treatment referrals. Alcohol reduction counseling interventions were guided by cognitive-behavioral therapy and motivational enhancement therapy delivered by psychosocial counselors over 3 months.

MEASUREMENTS

IPV perpetration was measured using the shortened Conflict Tactics Scale 2 and alcohol use was measured using timeline followback.

FINDINGS

BI and CoI participants reported reduced IPV perpetration at 3 months compared with SOC participants [BI: adjusted odds ratio (aOR) = 0.27, 95% confidence interval (CI) = 0.11, 0.65; CoI: aOR = 0.50, 95% CI = 0.22, 1.13]; the association was only significant for the BI group. Intervention effects were not sustained at 6 and 12 months. There was little evidence that alcohol use acted as a mediator (indirect effect, BI: aOR = 0.84, 95% CI = 0.63, 1.04; indirect effect, CoI: aOR = 0.86, 95% CI = 0.66, 1.03).

CONCLUSIONS

Among Vietnamese men receiving anti-retroviral therapy, alcohol reduction counseling interventions appeared to reduce intimate partner violence perpetration immediately post-intervention, but reductions were not sustained at 6 and 12 months and were not explained by alcohol reduction.

Harm from Others' Drinking Among Sexual Minority Adults in the United States

Purpose: Due to discrimination and stigma, sexual minority adults may be more likely than their heterosexual counterparts to experience harms from other people's drinking. We compared prevalence of second-hand alcohol harms for sexual minority and heterosexual adults in the United States. Methods: Data from the 2014-15 U.S. National Alcohol Survey (n = 5516; 10.2% sexual minority adults) were analyzed using logistic regression with survey weights to account for sampling and nonresponse. Multivariable models included simple main effects of sexual identity on the past-year harm outcomes, as well as interactions of drinker status with sexual identity. Results: In bivariate results stratified by sex, bisexual women were significantly more likely than heterosexual women to report all five types of harms. Lesbian respondents had greater odds relative to heterosexual women of reporting harm by a friend/coworker and assault or physical harm by a drinker. Bisexual identity among men was associated with greater odds of reporting assault/physical harm relative to heterosexual men in bivariate models. In adjusted models, differences by sexual identity were substantially reduced, with significance remaining only for friend/coworker-perpetrated harms and assault/physical harm among lesbian respondents compared with heterosexual women. For assault/physical harm, an interaction of sexual identity with the respondent's own drinking showed that the increased odds of harm associated with heavy drinking was even greater among sexual minority respondents (both bisexual and lesbian/gay respondents) than among heterosexual respondents. Conclusion: These findings underscore the importance of preventive interventions that consider disparities in risk for alcohol-related harms, particularly interpersonal violence, among sexual minority adults in the United States.

Drinking Context-Specific Dose-Response Models of Intimate Partner Violence Among an Urban Emergency Department Sample

OBJECTIVE

This cross-sectional study evaluates the association between physical intimate partner violence (IPV) and frequencies of drinking and volume consumed in six different contexts among a sample of urban emergency department (ED) patients.

METHOD

We obtained survey data from 1,037 married, cohabiting, or partnered patients (53% female; 50% Hispanic; 29% African American) at a Northern California safety-net hospital. Past-year physical IPV was measured with the Revised Conflict Tactics Scale. We asked patients about frequency of drinking and usual number of drinks consumed at bars, restaurants, homes of friends or relatives, own home, public places such as street corners or parking lots, and community centers or large events. Gender-stratified dose-response models were estimated for frequencies of IPV perpetration and victimization, with adjustment for sociodemographic and psychosocial factors, marijuana use, and spouse/partner problem drinking.

RESULTS

None of the women's context-based frequency and volume measures were associated with frequency of IPV victimization. Women's volume of alcohol consumed at home was associated positively with frequency of their IPV perpetration (β = .008, SE = .003, p < .01), and volume consumed in public places was associated negatively with this outcome (β = -.023, SE = .010, p < .05). Among men, none of the context-based frequency and volume measures were associated with frequency of either IPV outcome. Spouse/partner's problem drinking was associated with each gender's IPV victimization, and with IPV perpetration by men.

CONCLUSIONS

Frequency of drinking and volume consumed in specific contexts do not substantively contribute to frequency of IPV perpetration or victimization in this sample of urban ED patients.

Alcohol use, depressive symptoms, and intimate partner violence perpetration: A longitudinal analysis among men with HIV in northern Vietnam

Background

While the link between alcohol use and male-perpetrated intimate partner violence (IPV) has been well-established, research is needed to test whether psychosocial factors interact with alcohol use to exacerbate IPV perpetration. We tested whether depressive symptoms influenced the strength and/or direction of the alcohol-IPV relationship among men with HIV in Vietnam.

Methods

This study is a secondary analysis using data from a randomized controlled trial conducted in Thai Nguyen, Vietnam. Participants were clinic patients with HIV and hazardous alcohol use. Questionnaires were administered at baseline, three, six, and 12 months. Alcohol use was assessed as proportion of days alcohol abstinent. Analyses were restricted to males who reported being married/cohabitating at baseline (N = 313). Multilevel growth models were used to test whether time-varying depressive symptoms modified the time-varying effect of alcohol use on IPV perpetration.

Results

Time-varying depressive symptoms modified the effect of proportion of days alcohol abstinent on IPV perpetration. However, the pattern of effect modification was not as expected, as reporting depressive symptoms weakened the alcohol-IPV relationship. At times when participants screened negative for depressive symptoms, those who reported higher proportion of days alcohol abstinent than usual had significantly lower odds of IPV perpetration (Odds Ratio [OR] = 0.17, 95% Confidence Interval 0.06, 0.45, p = 0.0004). At times when participants screened positive for depressive symptoms, there was no observed effect of alcohol use on IPV perpetration (OR = 4.28, 95% CI 0.80, 22.78, p = 0.09).

Conclusion

The findings highlight the complex nature of the alcohol-IPV relationship and the need to investigate the intersection between hazardous drinking, mental health, and IPV. Men who concurrently report depressive symptoms and heightened alcohol use may be socially isolated from an intimate partner or experiencing fatigue, leading to less alcohol-related IPV perpetration. Mental health interventions addressing depression and alcohol misuse integrated into HIV services may reduce IPV perpetration.

Perpetration of Intimate Partner Violence Among Men Living with HIV in Northern Vietnam

We examined the prevalence of intimate partner violence (IPV) perpetration and characteristics of HIV-infected male perpetrators. The cross-sectional study was conducted in Vietnam with male antiretroviral treatment clients (N = 1099; mean age = 40.2 years). Bivariable associations were tested between psychological or physical/sexual IPV perpetration in the last 12 months and sociodemographic, psychosocial, and sexual behavioral factors using prevalence ratios. Factors significant at p < 0.10 were entered in multivariable models for each IPV outcome using a modified Poisson approach. Results showed 15.6% (N = 171/1099) reported perpetrating psychological IPV and 7.6% (N = 84/1099) perpetrating physical/sexual IPV in the last 12 months. HIV risk behaviors, including hazardous drinking and multiple sexual partners, having witnessed interparental violence as a child, and depressive symptoms were associated with perpetrating IPV. HIV interventions targeting HIV-infected men in Vietnam should intervene on IPV perpetration by addressing the co-occurring factors of sexual risk, depression, alcohol use, and child maltreatment that are correlated with IPV.

The association between blighted property remediation and domestic crime by alcohol availability

There is increasing evidence that place-based interventions reduce crime and interpersonal violence in urban settings. However, evidence concerning the impacts of these neighborhood interventions on domestic crime (crime between intimate partners, family, or household members) is inconclusive. We used data from a New Orleans, Louisiana, place-based blighted property remediation intervention to test the hypothesis that the intervention was associated with changes in domestic crime. Because there is evidence that alcohol availability is related to domestic crime, we also assessed whether this association was moderated by alcohol outlet density. We assessed overall associations using a difference-in-difference approach and assessed moderation using a triple-difference approach. The analytic sample consisted of 204 remediated lots and 612 non-remediated matched control lots over 84 months (2011-2017), for a total of 68,544 lot-months. In difference-in-differences analyses, the place-based intervention was associated with additional domestic crime incidence (β = 0.311, 95% CI: 0.016, 0.605; p = 0.039). In triple-difference analyses, on-premise bar density modified this association (β = -0.119, 95%CI: -0.147, -0.092; p < 0.001): in areas with higher bar density, increases in domestic crime were lower near remediated lots compared with control lots. Place-based interventions to reduce blighted properties may have contributed to fewer domestic crime incidents in areas with more bars.

Longitudinal analysis of alcohol use and intimate partner violence perpetration among men with HIV in northern Vietnam

BACKGROUND

Alcohol use is a known risk factor for male-perpetrated intimate partner violence (IPV), although few studies have been conducted globally and among men with HIV (MWH). We estimated the longitudinal effects of alcohol use on IPV perpetration among MWH.

METHODS

This study is a secondary analysis of randomized controlled trial data among male and female antiretroviral treatment patients with hazardous alcohol use in Thai Nguyen, Vietnam. Analyses were restricted to male participants who were married/cohabitating (N = 313). Alcohol use was assessed as proportion days alcohol abstinent, heavy drinking, and alcohol use disorder (AUD) using the Timeline Followback and Mini International Neuropsychiatric Interview questionnaire. Multilevel modeling was used to estimate the effects of higher versus lower average alcohol use on IPV perpetration (between-person effects) and the effects of time-specific deviations in alcohol use on IPV perpetration (within-person effects).

RESULTS

Participants with higher average proportion days alcohol abstinent had decreased odds of IPV perpetration (adjusted Odds Ratio [aOR] = 0.43, p = 0.03) and those with higher average heavy drinking and AUD had increased odds of IPV perpetration (Heavy drinking: aOR = 1.05, p = 0.002; AUD: aOR = 4.74, p < 0.0001). Time-specific increases in proportion days alcohol abstinent were associated with decreased odds of IPV perpetration (aOR = 0.39, p = 0.02) and time-specific increases in AUD were associated with increased odds of IPV perpetration (aOR = 2.95, p = 0.001). Within-person effects for heavy drinking were non-significant.

CONCLUSIONS

Alcohol use is associated with IPV perpetration among Vietnamese men with HIV. In this context, AUD and frequent drinking are stronger correlates of IPV perpetration as compared to heavy drinking.

Diminuição no uso de bebidas alcoólicas e a violência pelo parceiro íntimo

Introdução: A violência praticada por parceiro íntimo refere-se ao comportamento de parceiros ou ex-parceiros íntimos que resulta em dano físico, sexual ou psicológico, incluindo agressão física, coerção sexual, abuso psicológico e comportamento controlador. Sabe-se que o etilismo está associado ao aumento de tal violência. Objetivo: Analisar se a acompanhante do paciente em abstinência alcoólica referia menor índice de violência nesse período em relação ao tempo em que o mesmo fazia abuso de álcool. Métodos: Estudo observacional transversal no qual foram selecionados homens ex-etilistas atendidos no CAPSad de Maringá e suas parceiras. Foi utilizado um questionário para violência contra parceiro (HITS) composto de 4 perguntas objetivas, cuja pontuação varia de 4 até 20. Valores iguais ou superiores a 10 indicam violência. Resultados: Foram entrevistadas 53 mulheres de diversas faixas etárias e escolaridades. Desse total, 84,9% das participantes apresentaram pontuações menores no teste com o parceiro em abstinência em relação ao período em que o mesmo estava em uso/abuso de álcool. Das mulheres 15,1% não notaram diferença no nível de violência do acompanhante, estivesse ele em uso ou em abstinência alcoólica. Conclusões: Demonstrou-se claramente que o fato de cessar o consumo de bebidas alcoólicas reduziu o índice de violência infligida pelo parceiro.

Contextual characteristics of adults' drinking occasions and their association with levels of alcohol consumption and acute alcohol-related harm: a mapping review

BACKGROUND AND AIMS

There is a growing literature using event-level methods to estimate associations between contextual characteristics of drinking occasions, consumption levels and acute harms. This literature spans many research traditions and has not been brought together as a whole. This mapping review aimed to identify and describe the theoretical approaches to conceptualizing drinking occasions, study designs, predictors and outcome measures used in existing research with a view to identifying dominant approaches, research gaps and areas for further synthesis.

METHODS

Eligible papers studied adults' drinking occasions using quantitative event-level methods and considered one or more contextual characteristics (e.g. venue, timing or company) and at least one event-level consumption or acute alcohol-related harm outcome. We systematically searched Ovid MEDLINE, PsycInfo and the Web of Science Social Sciences Citation Index, extracting data on studies' theoretical approach, data collection methods, settings, populations, drinking occasion characteristics and outcome measures.

RESULTS

Searches identified 278 eligible papers (from 1975 to 2019), predominantly published after 2010 (n = 181; 65.1%). Most papers reported research conducted in the United States (n = 170; 61.2%) and half used student participants (n = 133; 47.8%). Papers typically lacked a stated theoretical approach (n = 203; 73.0%). Consistent with this, only 53 (19.1%) papers studied three or more occasion characteristics and most used methods that assume occasion characteristics do not change during an occasion (n = 189; 68.0%). The most common outcome type considered was consumption (n = 224; 80.6%) and only a few papers studied specific acute harm outcomes such as unprotected sex (n = 24; 8.6%), drink driving (n = 14; 5.0%) or sexual violence (n = 9; 3.2%).

CONCLUSIONS

Studies from 1975 to 2019 using event-level methods to estimate associations between contextual characteristics of drinking occasions, consumption levels and acute harms were largely focused on students and consumption outcomes, and most have considered a limited range of contextual characteristics.

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.

Drinking and Intimate Partner Violence Severity Levels Among U.S. Ethnic Groups in an Urban Emergency Department

BACKGROUND

Emergency departments (EDs) provide care to ethnically diverse populations with multiple health-related risk factors, many of which are associated with intimate partner violence (IPV). This paper examines ethnic-specific 12-month rates of physical IPV by severity and their association with drinking and other sociodemographic and personality correlates in an urban ED sample.

METHODS

Research assistants surveyed patients at an urban ED regarding IPV exposure as well as patterns of alcohol and drug use, psychological distress, adverse childhood experiences (ACEs), and other sociodemographic features.

RESULTS

The survey (N = 1,037) achieved an 87.5% participation rate. About 23% of the sample reported an IPV event in the past 12 months. Rates were higher (p < 0.001) among blacks (34%), whites (31%), and multiethnic (46%) respondents than those among Asians (13%) and Hispanics (15%). Modeled results showed that black respondents were more likely than Hispanics (reference) to report IPV (adjusted odds ratio [AOR] = 1.69, 95% confidence interval [CI] = 1.98-2.66, p < 0.05) and that respondents' partner drinking was associated with IPV (AOR = 1.85, 95% CI = 1.25-2.73, p < 0.01) but respondents' drinking was not. Use of illicit drugs, younger age, impulsivity, depression, partner problem drinking, ACEs, and food insufficiency were all positively associated with IPV.

CONCLUSIONS

There was considerable variation in IPV rates across ethnic groups in the sample. The null results for the association between respondents' drinking and IPV was surprising and may stem from the relatively moderate levels of drinking in the sample. Results for ethnicity, showing blacks as more likely than Hispanics to report IPV, support prior literature.

Understanding the relationship between alcohol outlet density and life expectancy in Baltimore City: The role of community violence and community disadvantage

This research investigated the relationship between alcohol outlet density (AOD) and life expectancy, as mediated by community violence and community disadvantage. We used linear regression models to assess bivariate and multivariate relationships. There was a negative bivariate association between liquor store density and average life expectancy (β = -7.3370, p < 0.001). This relationship was partially attenuated when controlling for community disadvantage and fully attenuated when controlling for community violence. Bars/taverns (i.e., on-premise) were not associated with average life expectancy (β = -0.589, p = 0.220). Liquor store density is associated with higher levels of community disadvantage and higher rates of violence, both of which are associated with lower life expectancies. Future research, potential intervention, and current related policies are discussed.
