Impulsivity and Reactive-Proactive Aggression as Mechanisms of Alcohol-Related Sexual Intimate Partner Violence Perpetration among Romantic Partners.

Background: Sexual intimate partner violence (S-IPV) commonly occurs within the contexts of committed romantic relationshops. Prior research has demonstrated the existence of a robust link between alcohol use and S-IPV. Despite this, few research studies have explored the etiological underpinnings of alcohol-related S-IPV perpetration, specifically. The present study examines the role of several key factors (i.e., problematic drinking, negative and positive urgency, proactive and reactive aggression) on S-IPV perpetration. Methods: Participants were 337 heavy drinking men and women in intimate relatinships who reported perpetrating some form of IPV toward their current partner within the past-year. A moderated-mediation model was used to determine how the key study variables interacted to predict S-IPV perpetration. Results: Results indicated that problematic drinking was positively correlated with both negative urgency and positive uregency. Findings also revealed that negative urgency, positive urgency, proactive aggression, and reactive aggression were all positively related to S-IPV perpetration. The indirect relationship between problematic drinking and S-IPV perpetration was mediated by positive urgency. Additionally, a significant main effect of proactive aggression on S-IPV perpetration was also detected. Conclusions: These findings suggest that impulsivity, specifically positive urgency, and proactive aggression may be under-appreciated constructs within the existing sexual aggression literature, and future research examining these variables as mechanisms explaining the association between the alcohol and S-IPV is warranted.

Impulsivity and Perpetration of Intimate Partner Aggression: The Moderating Effects of Negative Affective State and Alcohol.

Background: The goal of this study was to test the interactive effects of negative urgency, state negative affect, and alcohol intoxication on intimate partner aggression (IPA) perpetration. Methods: Heavy drinkers who recently perpetrated IPA completed self-report measures of impulsivity, were administered an alcohol or control beverage, and completed a laboratory aggression task. State negative affect was assessed unobtrusively via the Facial Action Coding System. Results: Consistent with our prediction, negative urgency was significantly and positively related to IPA when state negative affect was also high, but this relation was not significant when state negative affect was low. Conclusions: These results have implications for understanding the role of negative affect and impulsivity in IPA perpetration and for understanding trait models of impulsivity in general.

Sexual Violence Perpetration Within Intimate Relationships: An I3 Model Analysis of the Effects of Sexual Violence Victimization and Psychological Flexibility.

The I3 Model posits that intimate partner violence (IPV) is determined by the relative strength of instigatory, impellance, and inhibitory factors. Although much research has examined nonsexual IPV, few studies have used the I3 Model to examine sexual IPV. This study investigated the effects of sexual IPV victimization (an impellor) and psychological flexibility (an inhibitor) on sexual IPV perpetration within a dyadic framework. Participants nested within 617 intimate couples completed measures of psychological flexibility and sexual IPV perpetration and victimization. Results showed that Actor IPV victimization was positively and Actor psychological flexibility was negatively associated with Actor IPV perpetration. Among those who experienced low levels of IPV victimization, psychological flexibility inhibited IPV perpetration. This inhibiting effect did not extend to Actors who experienced high levels of IPV victimization. Findings highlight the complex interactions between I3 factors and support continued dyadic examination of IPV perpetration etiology.

Alcohol, conflict, and aggression in intimate relationships: A dyadic approach.

Intimate partner aggression (IPA) is a critical public health problem that requires clear and testable etiological models that may translate into effective interventions. While alcohol intoxication and a pattern of heavy alcohol consumption are robust correlates of IPA perpetration, there has been limited research that examines this association from a dyadic perspective. In the present review, we discuss compelling reasons for understanding dyadic factors that assist our understanding of alcohol-facilitated IPA, review the relatively small number of studies that have investigated such factors, and provide a theoretical and methodological framework for researchers to conceptualize how to model alcohol-facilitated IPA from a dyadic framework.

Problematic Drinking Mediates the Association Between Urgency and Intimate Partner Aggression During Acute Intoxication.

BACKGROUND: This study tested a moderated-mediation model whereby dimensions of impulsivity (i.e., negative urgency, positive urgency, sensation seeking, lack of premeditation, and lack of perseverance) differentially predict perpetration of physical intimate partner aggression (IPA) through problematic drinking in intoxicated and nonintoxicated heavy drinkers. METHODS: Participants were 249 heavy drinkers (148 men and 101 women) with a recent history of psychological and/or physical IPA perpetration toward their current partner recruited from 2 metropolitan U.S. cities. Participants completed questionnaires that assessed impulsivity and problematic drinking, consumed an Alcohol or No-Alcohol Control beverage, and completed a shock-based aggression task in which they were ostensibly provoked by their intimate partner. RESULTS: Results indicated an indirect effect of urgency on IPA through problematic drinking that was significantly more positive in intoxicated individuals. CONCLUSIONS: These findings implicate a tendency to act rashly in response to emotions as the specific dimension of impulsivity associated with problematic drinking, which in turn exacerbates risk for IPA perpetration. Results also suggest acute effects of alcohol are key in facilitating this mechanism.

Posttraumatic Stress Disorder Symptoms, Intimate Partner Violence, and Relationship Functioning: A Meta-Analytic Review.

This meta-analysis was the first study of which we are aware to investigate the association between Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV-TR; American Psychiatric Association, 2000) PTSD symptom clusters and parent, child, family, and marital/partner functioning problems (e.g., intimate partner violence [IPV] and intimacy). Of the 23 studies that met inclusion criteria, the sample was predominantly male (83.8%), Caucasian (65.0%), and from the military (98.9%). The average age was 43.65 years old (SD = 6.27); the average sample size was 397.4 (SD = 416.9; total N = 9,935). PTSD symptom clusters were assessed primarily by self-report (87.0%), with 8.7% using a rating by a clinician. We used fixed analysis following Fisher's r to z transformation and an unbiased weighing and summing of effect sizes within samples and across studies. We found a small association between hyperarousal and IPV (z = .20). We also found two moderate associations for the emotional numbing and avoidance symptom clusters: (a) with parent, child, and family functioning (z = .32, z = .28, respectively); and (b) with intimacy problems (z = .35, z = .42, respectively). We found two large associations for emotional numbing: marital and parent problems (z = .47) and parent, child, and family functioning problems (z = .32, respectively). Our findings suggested that treatments aim to lessen the effect on those who have close relationships with the individual with PTSD.

Social Information Processing in Anger Expression and Partner Violence in Returning U.S. Veterans.

We examined social information processing factors that could represent pathways through which posttraumatic stress disorder (PTSD) symptoms relate to anger expression and intimate partner violence (IPV) perpetration in returning U.S. veterans. The sample included 92 male Operation Enduring Freedom/Operation Iraqi Freedom veterans, primarily Caucasian (77.4%), with smaller numbers of African American, Asian, Hispanic or Latino, American Indian or Alaskan Native, and other minority participants (9.7%, 2.2%, 2.2%, 3.2%, and 5.3% respectively). The average age was 40.37 (SD = 9.63) years. Data were collected through self-report questionnaires (PTSD Checklist, State-Trait Anger Expression Scale, Revised Conflict Tactics Scales) and the Articulated Thoughts in Simulated Situations experimental protocol. Laboratory-based assessment of cognitive biases and hostile attributions were tested as mediators of associations between PTSD symptoms and anger expression and IPV. Among the PTSD symptom clusters, hyperarousal symptoms were most strongly associated with anger expression (r = .50) and IPV perpetration (r = .27). Cognitive biases mediated associations between PTSD total scores and 3 of 4 PTSD cluster scores as well as anger expression. Hostile attribution biases were also associated with IPV perpetration (r = .23). We discuss the implications of these findings for understanding social information processing mechanisms for the relationship between PTSD symptoms and aggression.

Anger, problematic alcohol use, and intimate partner violence victimisation and perpetration.

BACKGROUND: Anger and problematic alcohol use have been established as individual risk factors for intimate partner violence (IPV) victimisation and perpetration, but it is unknown how these factors convey risk for IPV perpetration for men and women within the context of mutually violent relationships. HYPOTHESES: Anger and problematic alcohol use were hypothesised to mediate the association between IPV victimisation and perpetration for men and women, with direct and indirect influences from partner variables. METHODS: Heterosexual couples (N = 215) at high-risk for IPV completed questionnaires indexing trait anger, problematic alcohol use and extent of past-year IPV perpetration and victimisation. An actor-partner interdependence modelling (APIM) framework was used to evaluate these cross-sectional data for two hypothesised models and one parsimonious alternative. RESULTS: The best-fitting model indicated that IPV victimisation showed the strongest direct effect on physical IPV perpetration for both men and women. For women, but not men, the indirect effect of IPV victimisation on physical IPV perpetration through anger approached significance. For men, but not women, the victimisation-perpetration indirect effect through problematic drinking approached significance. IMPLICATIONS FOR CLINICAL PRACTICE: The results suggest that anger and problem drinking patterns play different yet important roles for men and women in mutually violent relationships.

Dyadic violence and readiness to change among male intimate partner violence offenders.

BACKGROUND: Although readiness to change is associated with mandated partner violence treatment compliance and subsequent violent behaviour among male offenders (e.g. Scott and Wolfe, 2003; Eckhardt et al., 2004), our understanding of the factors associated with pretreatment change remains limited. Offender research indicates that individual and dyadic violent behaviour are highly variable and that such variability may provide insight into levels of pretreatment change (Holtzworth-Munroe and Stuart, 1994; Archer, 2002). AIMS/HYPOTHESES: We sought to examine the associations between indicators of change and individual as well as dyadic violence frequency in a sample of male partner violence offenders. METHOD: To determine whether severity and perceived concordance in the use of violence among male offenders and their female partners influenced readiness to change at pretreatment, 82 recently adjudicated male perpetrators of intimate partner violence were recruited into the current study and administered measures of readiness to change violent behaviour (Revised Safe at Home Scale; Begun et al., 2008) as well as partner violence experiences (Revised Conflict Tactics Scale; Straus et al., 1996). RESULTS: Analyses revealed an interaction between offender-reported male and female violence in the prediction of pretreatment readiness to change such that greater male violence was associated with greater readiness to change among males who reported that their female partners perpetrated low, but not high, levels of violence. Consistently, greater female violence was associated with lower readiness to change only among the most violent male offenders. CONCLUSIONS AND IMPLICATIONS FOR CLINICAL PRACTICE: Results provide support for the assertion that the most violent offenders may be the most resistant to partner violence intervention efforts, particularly when they perceive themselves to be victims as well. Enhanced motivational and couples programming may facilitate treatment engagement among the high-risk group of male offenders who report concordant relationship violence.

An Integrative Model of Alcohol-Facilitated Intimate Partner Aggression Perpetration in Sexual and Gender Diverse Couples.

OBJECTIVE: Sexual and gender diverse (SGD) individuals are at heightened risk for intimate partner aggression (IPA) perpetration relative to their heterosexual and cisgender peers. Alcohol is a well-established cause of IPA perpetration in cisgender, heterosexual couples; however, minimal research has investigated the alcohol-IPA perpetration link in SGD couples. The relative lack of work in this area is a major barrier to addressing this health disparity. SGD individuals experience unique stressors related to their and/or their partner's intersecting minoritized identities that are critical to understanding alcohol-IPA etiology and informing culturally affirming intervention programming. METHOD: We advance prior work by members of the authorship team (see Parrott et al., 2023a; Shorey et al., 2019) to propose an integrative theoretical model that invokes (1) the I3 Model to organize risk and resilience factors at the individual and dyadic level, and (2) Alcohol Myopia Theory to explain the mechanism by which proximal alcohol use facilitates IPA as a function of individual differences in those factors. RESULTS: This integrative model provides a framework to understand how the confluence of stigma, minority stressors, proximal alcohol use, and other factors contribute to IPA perpetration in SGD couples. DISCUSSION: Application of this integrative model has potential to facilitate more rigorous research (e.g., intensive longitudinal designs, dyadic analysis) focused on putative risk and resilience factors across the social ecology. Further, the model provides guidance for intervention development by identifying how individual (e.g., minority stress), relationship (e.g., relationship functioning), and structural factors (e.g., SGD stigma) interactively contribute to alcohol-facilitated IPA perpetration.

Evaluation of a single-session brief motivational enhancement intervention for partner abusive men.

The current study evaluated the efficacy of a single-session brief motivational enhancement (BME) interview to increase treatment compliance and reduce recidivism rates in a sample of 82 recently adjudicated male perpetrators of intimate partner violence (IPV). Batterer intervention program attendance and completion as well as re-arrest records served as the primary outcome measures and were collected 6 months post-adjudication. Results indicated that BME was associated with increases in session attendance and treatment compliance. BME was not directly associated with reductions in recidivism. The relationship between BME and treatment compliance was moderated by readiness to change such that BME participants with low readiness to change attended more sessions and were more likely to be in compliance with the terms of a treatment than control participants with low readiness, while participants with high readiness attended sessions equally, regardless of study condition. Results indicate that outcomes may be improved through treatment efforts that consider individual differences, such as one's readiness to change, in planning interventions for IPV perpetrators.

Emotion regulation and intimate partner violence perpetration: A meta-analysis.

Intimate partner violence (IPV) is a significant public health concern that affects millions of individuals each year. As such, research informing its prediction and prevention is paramount. Etiological models of IPV perpetration and empirical findings suggest that emotion regulation (ER) is associated with IPV perpetration. Further, research has suggested that depending on ER conceptualization, ER may predict either increased (e.g., risk factor) or decreased IPV perpetration (e.g., protective factor). Despite its documented association with IPV perpetration, and amenability to intervention, ER's aggregate association with IPV perpetration has not been evaluated. The present systematic review and meta-analysis analyzes ER's association with IPV perpetration. Two hundred and sixty-five effect sizes from 62 unique samples were included for analysis. Results suggested a small to moderate association between ER and IPV perpetration, the magnitude of which varied by ER construct, whether ER predicted increased or decreased IPV perpetration, and the type of IPV perpetration measured. The magnitude of association between ER and IPV perpetration did not vary by sample type or gender. Implications of these findings were reviewed in the context of meta-theoretical and clinically-focused models of IPV perpetration and suggestions for future research were explored.

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.

The instigating effects of isolation on substance-related intimate partner violence: A review.

In this article, we examine the empirical and theoretical support for the idea that experiences of isolation can intensify substance use, even among those in committed close relationships, and can increase the likelihood of negative conflict behaviors, including intimate partner violence (IPV). Cross-sectional, longitudinal, and laboratory-based research suggest that individuals and couples who report experiences of social exclusion and have fewer social supports experience more mental health problems, more negative emotional experiences, and higher levels of stress. These negative outcomes spur coping efforts to reduce these distressing states, which often involve pain-relieving substances such as alcohol. We describe how dynamic models of relationship conflict and IPV can integrate alcohol and substance use patterns among both individuals and couples to understand and predict contexts leading to conflict escalation and IPV perpetration.

Dealing with loss in the face of disasters and crises: Integrating interpersonal theories of couple adaptation and functioning.

The COVID-19 pandemic has highlighted the significant and varied losses that couples can experience during times of global and regional disasters and crises. What factors determine how couples navigate their close relationships during times of loss? In this paper, we elaborate and extend on one of the most influential frameworks in relationship science-the Vulnerability Stress Adaptation Model (VSAM, Karney and Bradbury, 1995)-to enhance the model's power to explain relationships during loss-themed disasters/crises. We do so by elaborating on attachment theory and integrating interdependence theory (emphasizing partner similarities and differences). Our elaboration and extension to the VSAM provides a comprehensive framework to guide future research and inform practice and policy in supporting relationships during and beyond loss-themed disasters/crises.

Relationship Dissatisfaction, Emotion Regulation, and Physical Intimate Partner Aggression in Heavy-Drinking, Conflict-Prone Couples: A Dyadic Analysis.

Relationship dissatisfaction is a known risk factor for intimate partner aggression (IPA). However, the possible effect of weak emotion regulation skills on this association is unclear, particularly in couples at risk for violence who drink alcohol heavily. This study examined the moderating effect of emotion regulation on the association between relationship dissatisfaction and physical IPA perpetration within a dyadic framework. Participants were 583 heavy drinking couples (N = 1,166) with a recent history of psychological and/or physical IPA recruited from two metropolitan cities in the United States. Multilevel models were used to examine effects within an actor-partner interdependence framework. Gender, Actor dissatisfaction, and Actor and Partner emotion regulation were associated with greater physical IPA perpetration. Actor relationship dissatisfaction predicted significantly greater physical IPA perpetration in Actors characterized by weak versus strong emotion regulation. Furthermore, partner relationship dissatisfaction predicted significantly increased physical IPA perpetration in Actors reporting weak, versus strong, emotion regulation. Gender did not significantly interact with model variables. Utilizing the I3 metatheoretical model of IPA within a dyadic framework, results provide insight into the interactive effects of relationship dissatisfaction and emotion regulation deficits on physical IPA perpetration, particularly in those individuals already at risk for perpetration.

Cognitive and Affective Mediators of Alcohol-Facilitated Intimate Partner Aggression.

This multisite study examined whether aggressive cognitions and facial displays of negative affect and anger experienced during provocation mediated the association between alcohol intoxication and intimate partner aggression (IPA). Participants were 249 heavy drinkers (148 men, 101 women) with a recent history of IPA perpetration. Participants were randomly assigned to an Alcohol or No-Alcohol Control beverage condition and completed a shock-based aggression task involving apparent provocation by their intimate partner. During provocation, a hidden camera recorded participants' facial expressions and verbal articulations, which were later coded using the Facial Action Coding System and the Articulated Thoughts in Simulated Situations paradigm. Results indicated that the positive association between alcohol intoxication and partner-directed physical aggression was mediated by participants' aggressive cognitions, but not by negative affect or anger facial expressions. These findings implicate aggressogenic cognitions as a mediating mechanism underlying the association between the acute effects of alcohol and IPA perpetration.

Alcohol-related relationship dissatisfaction: A putative mechanism for intimate partner aggression.

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

Alcohol, Affect, and Aggression: An Investigation of Alcohol's Effects Following Ostracism.

OBJECTIVE: Ostracism is distressing to those who experience it and people are motivated to find ways to cope, including self-medication or aggression. However, we know little about how alcohol intoxication may affect individuals' reactions to ostracism. This study investigates predictions informed by Alcohol Myopia Theory to observe how alcohol influences changes to one's affect, basic needs fulfillment, and aggression following ostracism. METHOD: Participants (N = 97) were randomly assigned to either consume an alcohol, placebo, or nonalcohol beverage, and then participate in a game that simulated ostracism. Following this, participants engaged in a task wherein they were able to aggress against an ostensible ostracizer. Affect and basic psychological needs were measured at baseline, post-ostracism, and post-aggression timepoints. RESULTS: Results indicated that all groups reacted adversely to ostracism and experienced partial recovery toward baseline for negative and positive affect and basic psychological needs. Further, alcohol facilitated recovery across these outcomes post-aggression for participants who felt more intoxicated. Alcohol, relative to the control beverages, increased ostracizer-directed aggression intensity for low trait physically aggressive, but not highly aggressive, people. CONCLUSION: This randomized study provides novel preliminary evidence suggesting that alcohol enhances aggressive urges toward ostracizers in those who are not typically aggressive. Those who feel more drunk when intoxicated, compared to those who feel less so, may experience greater recovery from ostracism after aggressing toward an ostracizer hinting at potentially pleasurable effects that must be replicated in future studies.

The structure of aggression in conflict-prone couples: Validation of a measure of the Forms and Functions of Intimate Partner Aggression (FFIPA).

Intimate partner aggression (IPA) is a complex construct composed of the means and the motivations by which a person harms his or her intimate partner. Existing measures only assess forms of IPA perpetration while neglecting to measure the motivations for aggressing. The present study sought to fill this lacuna by adapting and validating an existing measure of the forms and functions of adolescent peer aggression to assess IPA perpetration in adults. This new measure-the Forms and Functions of Intimate Partner Aggression (FFIPA)-comprises 4 latent dimensions of IPA (i.e., overt, relational, proactive, and reactive). Participants were 341 heavy-drinking heterosexual couples (N = 682) with a recent history of psychological and/or physical IPA recruited from 2 metropolitan cities in the United States. The FFIPA demonstrated good model fit and internal validity. Unique patterns of convergent and criterion-related validity supported the 4 dimensions of the FFIPA. Results also indicated women perpetrated significantly more overt and relational aggression than men. Findings support the FFIPA as a valid measure of the forms and functions of IPA perpetration. More important, as the only instrument that parses the forms and functions of IPA perpetration, the FFIPA delineates the unique motivations of an aggressive partner separately from the form of his or her aggressive behavior(s). Further replication is needed to generalize this measure to nonconflictual and other types of intimate relationships. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
