RESUMO
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.

RESUMO
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.

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.

The I3 Model is a meta-theoretical framework that posits intimate partner violence (IPV) perpetration is the product of three interactive factors: instigators, impellors, and inhibitors. The present study examined the effects of trait anger (an impellor), psychological flexibility (a disimpellor), and alcohol intoxication (a disinhibitor) on IPV perpetration. Participants were 249 heavy drinkers (41% female) who had perpetrated IPV toward their current partner in the past year. Participants completed self-report measures of trait anger and psychological flexibility, were randomly assigned to consume an alcoholic or non-alcoholic beverage, and then engaged in the Taylor Aggression Paradigm (Taylor, 1967) ostensibly against their current partner. Analyses detected a small-to-medium effect for two separate two-way interactions. First, a significant Beverage x Psychological Flexibility interaction was detected. Consistent with the I3 Model, explication analyses revealed that alcohol intoxication predicted higher levels of IPV perpetration in those who reported low, but not high, psychological flexibility (i.e., low disimpellance). Second, although the Beverage x Trait Anger interaction was non-significant, explication analyses revealed that alcohol intoxication predicted higher levels of IPV perpetration among those who reported low, but not high, trait anger (i.e., low impellance). These results have several potential treatment implications among alcohol-consuming clients.
