Intimate Partner Aggression Reporting Concordance and Correlates of Agreement Among Men With Alcohol use Disorders and Their Female Partners

How Does Denial, Minimization, Justifying, and Blaming Operate in Intimate Partner Abuse Committed by Men: A Systematic Review of the Literature

Intimate partner abuse (IPA) is widespread, and denial, minimization, justifying, and blaming (DMJB) are common among people who have committed IPA. Views on the function of DMJB in IPA are mixed, often based on the theoretical standpoint of the authors. This systematic review brings together the knowledge of how distorted accounts operate in IPA committed by men. A systematic review of primary research related to DMJB in heterosexual men who have committed to IPA was conducted. In all, 31 papers were found to meet the inclusion criteria (adult, male-to-female abuse, in western culture, peer reviewed and published in English) and were quality appraised. Data were extracted and analyzed using narrative synthesis. The findings indicate the way DMJB operates in this group is complex. It can represent facilitators of abusive behavior, a way to protect the individual's identity and self-esteem, and a tool men use instrumentally to achieve goals. Themes were present within and between studies highlighting the complex function of DMJB. A model representing the hypothesized intertwined function of DMJB for IPA is proposed. The limitations of the review are discussed and implications and recommendations for policy, practice, and future research are proposed.

Interpartner Agreement on Intimate Partner Violence Reports: Evidence From a Community Sample of Different-Sex Couples

An accurate assessment of intimate partner violence (IPV) is crucial to guide public policy and intervention. The Conflict Tactic Scales Revised (CTS-2) is one of the most widely used instruments to do so. Despite its good psychometric properties, research on interpartner agreement has pointed to low-to-moderate estimates, which generated some concerns about the validity of the results obtained through single-partner reports. This cross-sectional study introduces indexes that have not previously been used to assess interpartner agreement. Both partners' reports on perpetration and victimization were analyzed in a community sample of 268 different-sex couples. Our results generally pointed to better agreement levels on IPV occurrence than frequency, suggesting that the proxy method (i.e., using a single-partner report) could be a reliable method for assessing IPV occurrence but not its frequency in this population. Findings are discussed as well as the advantages and constraints of different IPV assessment practices.

Erectile Dysfunction, Suspicious Jealousy, and Partner-Directed Behaviors in Heterosexual Romantic Couples

Erectile dysfunction (ED) can have negative consequences for men and their intimate partners. The purpose of the present research was to replicate and extend the results of previous studies concerning the connections that ED has with partner-directed behaviors using a sample of heterosexual romantic couples. Specifically, we used an actor-partner interdependence mediation model to examine whether the associations that ED had with men's mate retention behaviors, partner-directed insults, partner-directed violence, and partner-inflicted injuries were mediated by suspicious jealousy, but not reactive jealousy. These associations were examined in 113 romantic couples, using men's self-reports, and partner-reports provided by their female partners. Results indicated that suspicious jealousy (but not reactive jealousy) mediated the associations that ED had with men's use of partner-directed behaviors, such that higher levels of ED were associated with men experiencing more suspicious jealousy, which, in turn, was associated with more cost-inflicting mate retention behaviors, benefit-provisioning mate retention behaviors, partner-directed insults, partner-directed violence, and partner-inflicted injury. However, there were some discrepancies between the reports provided by men and women such that these associations emerged more consistently in the partner-reports provided by women than in the self-reports provided by men. Discussion addresses evolutionary implications of these findings, as well as limitations of this research and directions for research concerning ED.

Physical Intimate Partner Violence Concordance Rates in Couples: Does CTS2 Item Order Matter?

Intimate partner violence (IPV) concordance rates between partners are low across national, community, and clinical samples. Discordance between partners' IPV reports is problematic given that self-report questionnaires, such as the CTS2, are commonly used to assess IPV. Moreover, most research is based solely on the report of one partner. Some have attributed this discordance to how CTS2 items are presented. The CTS2 presents items inquiring on the frequencies of perpetration by oneself and then one's partner in pairs. The present study examined whether IPV concordance rates improve if couples are administered a version of the CTS2 where all items assessing their partner's behaviors are presented first, followed by items assessing the respondents' behaviors. Additionally, the present study examined whether correlations between self-reported and partner-reported perpetration and victimization differ depending on the order in which CTS2 items are presented. Two samples of heterosexual couples were recruited from a large metropolitan area in the United States. The first sample was administered the CTS2 in its usual format. The second sample was administered a version of the CTS2 that presented items on one's partners' behavior first, followed by self-reported behavior. Results revealed that concordance rates among violent couples were higher in the group administered the CTS2 in its altered format, particularly agreement on male IPV perpetration. However, when agreement on minor and severe IPV was examined separately, concordance rates between groups were relatively similar for severe IPV. These findings suggest that altering the item presentation of the CTS2 may improve the interrater reliability of the Physical Assault Scale of the CTS2. Additional results are discussed.

Intimate Partner Violence Perpetration Denial and Underreporting in Cisgender Male Couples

Intimate partner violence (IPV) perpetrators often deny their actions, limiting opportunities for intervention. Cisgender male couples experience similar IPV rates to mixed-gender couples, yet less is known about how men in same-sex relationships deny or report their IPV behavior. This study aimed to describe perpetration denial across emotional, monitoring/controlling, and physical/sexual IPV, and to identify correlates of perpetration denial, in a convenience sample of male couples (N = 848; United States, 2016-2017). Past-year victimization and perpetration were measured with the IPV-Gay and Bisexual Men (GBM) scale; perpetration deniers were men whose self-reported perpetration contradicted their partner's reported victimization. Individual-, partner-, and dyadic-correlates of perpetration denial, by IPV-type, were identified using actor-partner interdependence models. We identified 663 (78.2%) perpetrators: 527 emotional; 490 monitoring/controlling; 267 physical/sexual. Thirty-six percent of physical/sexual-, 27.7% of emotional-, and 21.43% of monitoring/controlling-perpetrators categorically denied their actions. Depression was negatively associated with denying monitoring/controlling-perpetration (odds ratio 95% confidence interval: 0.91 [0.84, 0.99]) and physical/sexual-perpetration (0.91 [0.83, 0.97]); dyadic differences in depression were associated with emotional-perpetration denial (0.95 [0.90, 0.99]). Recent substance users had 46% lower odds of monitoring/controlling-denial (0.54 [0.32, 0.92]), versus non-users. Partner-race and employment were also significantly associated with emotional perpetration denial. This study highlights IPV denial's complexities, including differences across IPV types. Further investigations into how cisgender men in same-sex couples perceive and report various types of IPV perpetration will provide valuable insight into how an underserved and understudied population experiences IPV.

Agreement Between Mother and Father Reports of IPV in a Sample of Child Protection Referred Coparents

Accurate assessment of intimate partner violence (IPV) using standardized measures can be a challenge as there is often discrepancy between partner reports, with previous research indicating very poor concordance between partners using the Conflict Tactics Scale. This study examines agreement between coparent reports of IPV using the Abusive Behavior Inventory (ABI) from 282 coparent dyads referred for Fathers for Change, an IPV intervention by the Department of Children and Families (DCF). Differences in partner concordance using intraclass correlations were examined based on type of violence, marital status/cohabitation, race/ethnicity and substance misuse problems. Intraclass correlations were also calculated for eight power and control items unique to the ABI. Overall agreement between coparents was poor. However, there was greater concordance about mothers' who have used IPV toward fathers than fathers' use of IPV toward mothers. There was lower agreement between reports of physical than psychological IPV especially for white coparents. All types of coparent relationships showed low levels of agreement, but cohabiting coparents showed the highest levels of agreement when reporting fathers' IPV. In cases with one parent exhibiting substance misuse, concordance between reports of IPV increased. Results are consistent with prior findings that women report higher IPV than fathers even when assessments are done in the context of a DCF IPV treatment referral.

Between-Reporter Agreement Among Couples: Exploring Nonlinear Patterns in Marital Conflict

This study compares self-reported and spouse-reported frequencies of various types of behaviors couples use in marital conflict using data from Turkish Family Structure Survey (2016), which included 9,636 couples. Existing literature reported low levels of agreement among couples. These studies measured between-reporter agreement levels among couples with linear models which report cumulative scores. However, we hypothesized that low levels of agreement reported in the literature might be due to nonlinear patterns in the self-reported and spouse-reported frequencies. To detect such nonlinear patterns, we compared self-reported and spouse-reported frequencies for each level (frequency) of using the types of conflict behavior styles we investigated. This allowed us to explore the patterns of agreement or disagreement at the low, medium, or high levels of using these conflict style behaviors. Findings of this study confirmed our hypothesizes. There are meaningful nonlinear patterns that are not detectable with cumulative comparative scores. There are also differences in these patterns across the types of conflict behaviors we looked at. For example, the nonlinear patterns we observed for aggressive conflict behavior types are different from the patterns for passive conflict behavior types. We also found that these patterns are different for husbands and wives. This paper highlights the limited capacity of linear models for exploring between-reporter agreement levels and it calls for the consideration of using nonlinear methods for these types of systematic investigation. The major limitation is the lack of analysis on the effect of sociodemographic factors on the observed discrepancies other than gender.

Suicide as an interpersonal phenomenon: Dyadic methodological and statistical considerations in suicide research

Interpersonal risk and resilience factors are prominent in current conceptual models of suicide. A growing body of empirical evidence links suicidal thoughts and behaviors to a range of interpersonal phenomenon adding further support to the value of this line of inquiry. At present, research on interpersonal phenomenon focuses on assessing individuals' perceptions of interpersonal phenomenon, such as appraisals of burdensomeness, experienced loneliness, and thwarted belongingness. As this line of research continues to develop, we argue that it would be valuable to consider incorporating conceptual models of interpersonal phenomenon and corresponding methodological approaches from closely allied fields. After providing a brief overview of interpersonal models of suicide, we present an introduction to conceptual models of interpersonal phenomenon developed in relationship science, describe how these models can be applied to the study of interpersonal phenomenon in suicide research, and close with a guided tutorial on data collection and statistical analysis methods for testing hypotheses derived from these conceptual approaches. References for additional reading are provided, and the Appendix S1 provides simulated data sets and statistical code for the analyses in the tutorial section.

Do household asset wealth measurements depend on who is surveyed? Asset reporting concordance within multi-adult households in rural Uganda

BACKGROUND

In resource-limited settings, the Filmer & Pritchett asset index is frequently used to measure household economic status. Little is known about how its validity is affected by differential reporting or recall within households.

METHODS

As part of a whole-population survey in a rural region of southwestern Uganda, we elicited household asset information from married dyads (404 men and 404 matched women) residing within the same households. We assessed the extent to which the asset index yielded differing measures of relative household wealth, depending on whether the husband's or wife's survey data were used in its calculation. To estimate agreement, we used Cohen's κ for binary and categorical variables, and Cronbach's α for continuous variables. We also assessed the extent to which asset wealth quintiles assigned based on husbands' vs wives' reporting were concordant, and whether discordance was related to demographic characteristics.

RESULTS

For most individual assets, agreement ranged from moderate to very good. Asset index scores based on husbands' vs wives' reporting were positively correlated (Pearson r = 0.85). Corresponding wealth quintiles were moderately concordant (weighted κ = 0.65); 171 households (43%) differed by one or more quintiles when the husbands' vs wives' reporting was used, and 43 (11%) differed by two or more quintiles. Concordance in asset wealth quintile could not be explained by joint educational attainment, age, or age difference.

CONCLUSIONS

There is significant intra-household variability in household asset reporting that can materially affect how households are classified on a widely used measure of relative household asset wealth.

Is Readiness to Take Action Among Women in Violent Relationships a Catastrophic Phenomenon?

Taking action among women in violent relationships appears to involve sudden changes and reversals after periods of building stress, suggesting that decision making is a "catastrophic" phenomenon. This study sought to determine whether readiness-to-change is best modeled as a cusp catastrophic (CCM) phenomenon among women in violent relationships. A total of 143 women who experienced violence in the previous month completed baseline and end-of-study interviews assessing her hope, coping strategies, social network, and readiness-for-action (seeking help, taking legal action, and leaving) concerning the violence. Daily assessments of his violent behavior, forgiveness sought and given, and her perceived need-for-action were collected via telephone Interactive Voice Response for 8 weeks. Using regression analysis, the impact of factor-analyzed asymmetry (violence burden) and bifurcation (hope and cope, support, forgiveness, and number of children) variables on the outcomes (readiness-for-help, legal action, and leaving) was modeled, comparing the CCM against linear models to determine which model accounts for the most variance in each outcome. Cusp catastrophe models for all three actions accounted for more variance than either linear model comparison, but violence burden was only relevant to readiness-for-help and different bifurcation variables were at work for each action. While forgiveness was an important bifurcation factor in readiness-for-help and number of children served as the bifurcation factor for readiness-for-legal-action, readiness-to-leave was more complex with both number of children and hope-and-cope as bifurcation factors. Not only should we expect sudden changes in readiness but efforts to facilitate decision making should focus on addressing the bifurcation factors that may distort her interpretation of reality.

Concordance in the reporting of intimate partner violence among male-male couples

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.

Relationship satisfaction and interpartner agreement about acts of physical and psychological aggression: a multilevel analysis

BACKGROUND

To analyze, in a multilevel context, the impact of individual-level relationship satisfaction on couples' mean reports of aggression and agreement about acts of physical and psychological aggression.

METHODS

We conducted a quota sampling method to recruit a community sample of 2.988 heterosexual adult couples from the Region of Madrid (Spain).

RESULTS

The percentages of intimate partner aggression considering the highest report of aggression in the couple were around 60% of psychological aggression and 15% of physical aggression. Couples that used aggressive tactics showed low to moderate levels of agreement about physical and psychological aggression. Multilevel models confirm that women's relationship satisfaction had a significant influence on the level of agreement about acts of psychological aggression, but the same pattern of results was not observed for men. On the other hand, men and women's relationship satisfaction had no significant influence on the level of agreement about physical aggression.

CONCLUSIONS

Psychological aggression plays a more relevant role in women's relationship satisfaction than physical aggression.

A Latent Profile Analysis of Aggression and Victimization Across Relationship Types Among Veterans Who Use Substances

OBJECTIVE

This study examined patterns of violence victimization and aggression in both intimate partner and nonpartner relationships among U.S. military veterans using latent profile analysis to identify subtypes of violence involvement.

METHOD

Participants were 839 substance use treatment-seeking veterans (93% male) from a large Veterans Affairs Medical Center who completed screening measures for a randomized controlled trial.

RESULTS

Past-year violence involvement, including both intimate partner violence (IPV) and nonpartner violence (NPV), was common in the sample, although NPV occurred at somewhat higher rates. When we included either IPV or NPV aggression or victimization, more than 40% reported involvement with physical violence, 30% with violence involving injury, and 86% with psychological aggression. Latent profile analysis including both aggression and victimization in partner and nonpartner relationships indicated a four-profile solution: no/low violence (NLV; n = 377), predominantly IPV (n = 219), predominantly NPV (n = 134), and high general violence (HGV; n = 109). Multinomial logistic regression analyses revealed that, compared with the NLV group, the remaining three groups differed in age, cocaine use, posttraumatic stress disorder (PTSD) symptoms, and legal involvement. Legal issues appeared to differentiate the profiles most, with the predominantly NPV and HGV profiles reporting more instances of driving under the influence and the HGV profile reporting legal problems related to aggression.

CONCLUSIONS

IPV and NPV are fairly common among veterans seeking substance use treatment. The clinical characteristics of violence profiles indicate that cocaine use, PTSD symptoms, and legal involvement are treatment needs that vary with violence profile and may be useful for clinical decision making.

Military/Civilian Risk Markers for Physical Intimate Partner Violence: A Meta-Analysis

This meta-analysis compared risk markers for perpetration of physical intimate partner violence (IPV) among military and civilian males. We also examined strength of risk markers among male and female service members. In total, 36 military studies and 334 civilian studies, which reported 883 effect sizes, were included in the analyses. Results revealed more similarities than differences in risk markers for IPV among military and civilian males and among military males and females. Of the risk markers examined, relationship satisfaction and alcohol problems were significantly stronger risk markers for IPV among civilian males compared to military males. Perpetrating emotional abuse was a significantly stronger risk marker for IPV perpetration among military females compared to military males. Recommendations for IPV prevention and intervention are discussed.

Intimate Partner Violence in Men Voluntarily Attending Treatment: A Study of Couple Agreement

Most studies examining couple agreement on intimate partner violence (IPV) have found low agreement on levels of violence. This study explored agreement on male-perpetrated IPV in a sample of 93 couples where the man was voluntarily seeking IPV treatment. Five different types of violence were assessed: physical, physically controlling, psychological, property, and sexual. The results were mixed. When disagreement was found, this resulted from men attending IPV treatment reporting less violence than their partners. However, only psychological violence was consistently reported differently. Reliability estimates ranged from poor to moderate. Couples reported on sexual violence with less reliability than physical or physically controlling violence when referring to a typical month last year. Measurement of different types of violence among both partners in a couple is recommended in clinical and research settings as well as thorough discussions with clients voluntarily enrolled in treatment for IPV on what constitutes violence.

Examining the Role of Antisocial Personality Disorder in Intimate Partner Violence Among Substance Use Disorder Treatment Seekers With Clinically Significant Trauma Histories

This study examined the associations among posttraumatic stress disorder (PTSD) symptom severity, antisocial personality disorder (ASPD) diagnosis, and intimate partner violence (IPV) in a sample of 145 substance abuse treatment-seeking men and women with positive trauma histories; sex was examined as a moderator. ASPD diagnosis significantly predicted both verbal and physical aggression; sex moderated the association between ASPD diagnosis and physical violence. PTSD symptom severity significantly predicted engaging in verbal, but not physical, aggression. Overall, these results suggest that an ASPD diagnosis may be an important risk factor for engaging in IPV among women seeking treatment for a substance use disorder.

The association between substance use and intimate partner violence within Black male same-sex relationships

Compared with the extant research on heterosexual intimate partner violence (IPV)-including the knowledge base on alcohol and illicit drug use as predictors of such IPV-there is a paucity of studies on IPV among men who have sex with men (MSM), especially Black MSM. This study investigates the prevalence of experiencing and perpetrating IPV among a sample of Black MSM couples and examines whether heavy drinking and/or illicit substance use is associated with IPV. We conducted a secondary analysis on a data set from 74 individuals (constituting 37 Black MSM couples) screened for inclusion in a couple-based HIV prevention pilot study targeting methamphetamine-involved couples. More than one third (n= 28, 38%) reported IPV at some point with the current partner: 24 both experiencing and perpetrating, 2 experiencing only, and 2 perpetrating only. IPV in the past 30 days was reported by 21 (28%) of the participants: 18 both experiencing and perpetrating, 1 experiencing only, and 2 perpetrating only. Heavy drinking and methamphetamine use each was associated significantly with experiencing and perpetrating IPV throughout the relationship as well as in the past 30 days. Rock/crack cocaine use was significantly associated with any history of experiencing and perpetrating IPV. Altogether, IPV rates in this sample of Black MSM couples equal or exceed those observed among women victimized by male partners as well as the general population of MSM. This exploratory study points to a critical need for further efforts to understand and address IPV among Black MSM. Similar to heterosexual IPV, results point to alcohol and illicit drug use treatment as important avenues to improve the health and social well-being of Black MSM.

Social desirability and partner agreement of men's reporting of intimate partner violence in substance abuse treatment settings

Estimates indicate that intimate partner violence (IPV) occurs in approximately 30% of relationships and up to 85% of the relationships of men in substance abuse treatment. However, partners consistently display poor agreement in reporting the presence of IPV. Social desirability is frequently offered as the primary reason for under-reporting of IPV by perpetrators. The goal of the current study was to explicitly test the social desirability hypothesis using both partners' reports of negotiation, psychological aggression, physical aggression, sexual aggression, and injuries in a substance abuse treatment sample. A total of 54 males and their female partners were recruited from a residential adult substance use treatment facility. Consistent with prior literature, partners displayed poor agreement about the presence of different types of IPV. The male partner's social desirability was not associated with his reporting of male-to-female physical aggression, psychological aggression, or injuries. Men who engaged in higher levels of self-deceptive enhancement and lower levels of impression management were more likely to under-report male-to-female sexual coercion. Overall, the findings question the generalized importance of social desirability in IPV reporting in substance abuse treatment populations.

Distal and proximal factors associated with aggression towards partners and non-partners among patients in substance abuse treatment

Studies of violence in substance use disorder (SUD) treatment settings typically focus on partner aggression (PA) although non-partner aggression (NPA) is also a common problem. This study examines potentially distinct paths of distal and proximal risk factors related to aggression towards non-partners (NPA) and partners (PA) among a SUD treatment sample. The sample included 176 adults reporting past-year violence. Bivariate analyses indicated several distal and proximal factors were associated with NPA and PA. According to multivariate, multiple mediation analyses youth aggression history was a factor for both NPA and PA. Alcohol and cocaine use and psychological distress were associated with NPA; marijuana use was associated with PA. There also was evidence of indirect effects of distal factors on NPA and PA. The results suggest that there may be substantially different dynamics associated with NPA and PA, and have implications for developing screening, assessment and treatment protocols targeting violence among individuals in SUD treatment.

Multi-day recurrences of intimate partner violence and alcohol intake across dynamic patterns of violence

RATIONALE, AIMS AND OBJECTIVES

Consistent links exist between male alcohol intake and male-perpetrated intimate partner violence (IPV) as well as female alcohol intake and female-perpetrated IPV. However, the nature of the relationship remains unclear. This study attempted to identify unique alcohol-violence patterns within three different types of relationship dynamics to better understand the alcohol-violence relationship and its role in violence dynamics.

METHOD

Two hundred women in abusive relationships were recruited from six primary care clinics. Subjects completed daily assessments of their relationship using interactive verbal response via telephone for 12 weeks. Dynamic patterns (periodic, chaotic, random) were determined by positive versus negative Lyapunov exponents and measures of correlation dimension saturation. To identify recurrent day-to-day activities, we used orbital decomposition (based on symbolic dynamics).

RESULTS

Periodic dynamics included daily reports with mutual abuse and alcohol intake while random dynamics included a variety of patterns, especially those involving unequal mutual abuse. Unique strings for each dynamic pattern were examined. Periodic dynamics involved heavy alcohol intake by the husband or mutual moderate-severe violence. Random dynamics uniquely involved mutual verbal abuse with husband's alcohol intake on same or different days as well as husband-perpetrated moderate-severe violence with or without husband-perpetrated minor violence. Chaotic dynamics uniquely involved combinations from wife-perpetrated minor violence alone to combinations of husband's heavy alcohol intake (with or without husband-perpetrated minor violence), mutual verbal abuse, and husband-perpetrated verbal abuse (with or without husband's heavy alcohol intake).

CONCLUSION

Recurrent 4-day patterns were observed. Each dynamic pattern was characterized by recurrent strings unique to that pattern.

Agreement between veteran and partner reports of intimate partner aggression

We examined intimate partner aggression (IPA) reporting concordance between veterans and their partners and investigated relationship satisfaction, posttraumatic stress disorder (PTSD) symptoms, and relationship attributions as correlates of IPA reporting discrepancies. The sample consisted of 239 veterans of different service eras and their intimate partners. Veterans and partners reported their physical and psychological IPA perpetration and victimization over the past 6 months. Methodological improvements over prior concordance studies included the use of clinician-assessed PTSD symptoms and the assessment of relationship attributions via observational coding of couples' conflict interactions. Results suggested low to moderate levels of agreement between veterans and partners and indicated that relationship satisfaction was associated with reporting less IPA than one's partner reported, replicating prior concordance findings. Previous concordance findings with self-reported PTSD symptoms were also reproduced in the current study using clinician-assessed PTSD symptoms. Veterans' PTSD symptoms were associated with reporting less IPA than their partners reported and partners' PTSD symptoms were associated with reporting more IPA than the veterans reported. Additionally, we found an association between relationship attributions and reporting discrepancies. For both dyad members, making more positive and less negative relationship attributions was associated with reporting less IPA than one's partner reported. Findings underscore the difficulty of obtaining objective self-reports of adverse behavior and highlight factors that may influence such reports. Clinically, this information could be used to better identify cases in which obtaining collateral reports of IPA are particularly warranted.

Genetic and environmental influences on alcohol use problems: moderation by romantic partner support, but not family or friend support

BACKGROUND

High levels of various forms of social support (e.g., romantic partner, family, friend) have a buffering effect on alcohol use outcomes in both adolescents and adults. The etiological associations among these variables have not been well studied. One possibility is that social support may buffer against inherited genetic predispositions to alcohol problems. Previous work has examined gene-environment interactions (G×E) for alcohol use disorders, but never for social support in adult twins.

METHODS

In the current study, biometric modeling techniques were implemented to examine genetic and environmental components of variance of social support and alcohol use problems in a sample of 672 adult twin pairs. Using biometric moderation models that estimate G×E in the presence of gene-environment correlation (rGE), analyses examined how genetic and environmental influences on alcohol use problems varied as a function of romantic partner support, family support, and friend support.

RESULTS

Genetic and environmental components of variance for alcohol use problems varied depending on the level of romantic partner support, with greater environmental influences found at the low level of support. Family and friend support, however, failed to show moderating effects.

CONCLUSIONS

The current research has implications for expanding our understanding of what types of social support may trigger or suppress genetic and environmental influences on alcohol use problems.

The role of illicit substance use in a conceptual model of intimate partner violence in men undergoing treatment for alcoholism

Illicit substance use (ISU) predicts intimate partner violence (IPV) above and beyond alcohol use and other known IPV correlates. Stuart and colleagues (2008) provided evidence for a theoretical framework by which ISU contributes both directly and indirectly to IPV. We sought to replicate and extend their findings using data from 181 married or cohabiting heterosexual couples in which the male had recently begun a substance abuse treatment program and met criteria for alcohol dependence (97%) or abuse (3%). Using SEM, we found that (a) Stuart et al.'s model provided a good fit to the data; (b) men's cocaine use and women's sedative use emerged as particularly relevant to their respective perpetration of IPV; (c) a positive association between men's antisociality and physical aggression was mediated by increased stimulant use; and (d) the specific pattern of IPV predicted by women's sedative use differed across levels of aggression severity. These findings not only highlight the direct role of ISU in relationship aggression, but also support a larger theory-driven model comprising various proximal and distal precursors of IPV.

A multilevel examination of interpartner intimate partner violence and psychological aggression reporting concordance

Low concordance of reports across partners has consistently been observed when partners report the frequency of intimate partner violence (IPV) and psychological aggression (PA) in their relationship. Researchers have been unsuccessful in the quest to discover systematic biases across reporters, perhaps due to examining constructs that are not the source of bias (e.g., gender, victim/perpetrator status) or examining potentially fruitful constructs using underpowered statistics or erroneous conceptualizations (e.g., examining variables at a dyadic, rather than an individual, level). We used multilevel modeling with two samples (Ns = 88 and 164 couples) to examine husbands' and wives' relationship satisfaction as individual-level correlates of husband- and wife-perpetrated IPV and PA reporting concordance. Consistent with prior literature, low to moderate levels of agreement were observed, and gender and victim/perpetrator status were not consistently associated with reporting concordance. In contrast, for both husbands and wives, relationship satisfaction was associated with reporting concordance such that high relationship satisfaction was related to reporting less of one's partner's PA than the partner reported, whereas low relationship satisfaction was related to reporting more of one's partner's PA than the partner reported. A similar pattern of results emerged for the reporting of IPV, but results did not cross validate between samples. These findings suggest that relationship satisfaction may lead to either reluctance, or increased willingness, to attribute negative relationship events to partner behavior, potentially due to partner blame and relationship schemas. In addition, the influence of individual-level factors may be occluded when aggregated across partners to examine correlates of interpartner reporting concordance.

Improving risk assessment of violence among military veterans: an evidence-based approach for clinical decision-making

Increased media attention to post-deployment violence highlights the need to develop effective models to guide risk assessment among military Veterans. Ideally, a method would help identify which Veterans are most at risk for violence so that it can be determined what could be done to prevent violent behavior. This article suggests how empirical approaches to risk assessment used successfully in civilian populations can be applied to Veterans. A review was conducted of the scientific literature on Veteran populations regarding factors related to interpersonal violence generally and to domestic violence specifically. A checklist was then generated of empirically-supported risk factors for clinicians to consider in practice. To conceptualize how these known risk factors relate to a Veteran's violence potential, risk assessment scholarship was utilized to develop an evidence-based method to guide mental health professionals. The goals of this approach are to integrate science into practice, overcome logistical barriers, and permit more effective assessment, monitoring, and management of violence risk for clinicians working with Veterans, both in Department of Veteran Affairs settings and in the broader community. Research is needed to test the predictive validity of risk assessment models. Ultimately, the use of a systematic, empirical framework could lead to improved clinical decision-making in the area of risk assessment and potentially help prevent violence among Veterans.

Effects of physical and verbal aggression, depression, and anxiety on drinking behavior of married partners: a prospective and retrospective longitudinal examination

In an ethnically diverse sample of 195 married couples, we conducted a latent factor growth analysis to investigate the longitudinal link (4 time points over 4 1/2 years) between marital aggression (physical and verbal aggression self- and partner-reports) and individual internalizing symptoms (depression and anxiety) as they relate to trajectories of alcohol use among husbands and wives. Alcohol use was operationalized as a latent factor with self- and partner reports of problem drinking as measured by the Michigan Alcoholism Screening Test and the Alcohol Dependence Scale. Verbal aggression by husbands or wives, by itself, has no effect on their alcohol use over time. In conjunction with depression, however, verbally aggressive husbands do have elevated drinking levels. The effects of husbands' and wives' physical aggression on their own and their partners' drinking behavior were also significant. This study is one of the first to examine the change over time in alcohol use for marital partners as related to marital aggression and internalizing symptoms. Our results shed light on areas of marital functioning (aggression, internalizing, alcohol use) that have not been investigated in conjunction with each other in a longitudinal design.

Psychological aggression, physical aggression, and injury in nonpartner relationships among men and women in treatment for substance-use disorders

OBJECTIVE

This study focused on the prevalence and predictors of psychological aggression, physical aggression, and injury rates in nonintimate partner relationships in a substance-use disorder treatment sample.

METHOD

The sample included 489 (76% men, 24% women) participants who completed screening measures for inclusion in a randomized control trial for an aggression-prevention treatment. Primary outcome measures included rates of past-year psychological aggression, physical aggression, and injury (both from the participant to nonpartners and from nonpartners to the participant). Potential predictors included individual factors (e.g., age, gender), developmental factors (e.g., family history of drug use, childhood physical abuse), and recent factors (e.g., depression, cocaine use).

RESULTS

Rates of participant-to nonpartner psychological aggression (83%), physical aggression (61%), and injury (47%) were high, as were rates of nonpartner-to-participant aggression. Bivariate analyses revealed significant relationships between the aggression outcomes and most of the individual, developmental, and recent factors. However, multivariate analyses (zero-inflated Poisson regression) revealed that age, treatment status, current symptoms of depression, heavy periods of drinking, and cocaine use were related most frequently to the occurrence of aggression to and from nonpartners.

CONCLUSIONS

Nonpartner aggression may be as common within a substance-use disorder sample as partner aggression, and it is associated with heavy drinking episodes, cocaine use, and depressive symptoms. The findings highlight the need for the development of effective violence interventions addressing violence in nonpartner relationship types.

Treatment needs of men and women with violence problems in substance use disorder treatment

This study examined treatment needs of men and women in substance use disorder (SUD) treatment. The sample (n = 489) was recruited between 2006 and 2007 from a Midwestern state in the United States, and participants were grouped based on injury occurring in partner and nonpartner relationships in the past year. Rates of injury across relationship types were alarming with over 54.8% reporting injuring another person and 55.4% reporting being injured. Overall, those injuring nonpartners or both partners/nonpartners had more severe problems. Implications of the findings for SUD treatment settings and a model for integrated violence prevention are discussed.

Partner aggression among men and women in substance use disorder treatment: correlates of psychological and physical aggression and injury

This study examined intimate partner aggression in a sample of 489 participants enrolled in substance use disorder treatment, and expands on prior research by including measures of various forms of aggression, a mixed gender sample (76% men, 24% women), and measurement of several potential risk domains. Aggression measures included both participant-partner and partner-to-participant psychological aggression, physical aggression and injury. Analyses focused on the role of distal and proximal risk factors, including demographics, history of childhood physical and sexual abuse, and family history of problems with alcohol, drugs and depression, as well as recent substance use and symptoms of depression. Overall rates of participant-partner psychological aggression (77%), physical aggression (54%) and injuring partners (33%) were high, as were rates of partner-to-participant psychological aggression (73%), physical aggression (51%), and injury (33%). Several distal (family history variables, physical abuse) and proximal factors (binge drinking, several different drugs, depressive symptoms) were bivariately related to most of the aggression measures. However, according to multivariate analyses predicting aggression and injury measures, binge drinking and cocaine use were the drugs significantly associated with most measures, depression symptoms also were related to most aggression and injury measures, and a history of reported childhood physical abuse was related to all frequency of aggression and injury measures among those reporting such behaviors. Overall, the high rates of aggression among both men and women observed in this study further illustrate the need for interventions targeting substance use and aggression, and for further research regarding the inter-relationships among substance, aggression and depressive symptoms.

Assessment of interpersonal aggression and violence: introduction to the special issue

Violence and interpersonal aggression are considered major public health problems throughout the world. Yet there is considerable variability in how these terms are operationalized, measured, and studied in the social sciences, which can lead to ambiguity and confusion in the field. In this introduction to the special issue, the authors highlight some of the difficulties inherent in studying interpersonal aggression and violence and briefly review the heterogeneous nature of the research conducted in this area. The authors conclude with a summary of the key findings of the articles that appear in this special issue.
