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

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. 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. 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. 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.

Interactive effects of mindfulness and negative urgency on intimate partner aggression perpetration.

Intimate partner aggression (IPA) is a costly and incompletely understood phenomenon. Negative urgency, the tendency to act impulsively in response to negative affect, is predictive of IPA perpetration. Mindfulness, by virtue of its emphasis on nonreactivity to negative affect, is an opposing force to urgent tendencies that may mitigate the negative urgency-IPA link. Yet, no research to date investigates the interactive effects of negative urgency and mindfulness on IPA perpetration. Two studies were conducted that measured and manipulated multiple facets of mindfulness alongside measures of negative urgency and tendencies of IPA perpetration (combined N = 508 undergraduate students in monogamous intimate relationships). Counter to our preregistered predictions, we found that negative urgency's association with greater IPA perpetration increased at higher levels of mindfulness. These findings suggest that mindfulness may not be a protective factor against IPA perpetration for individuals higher in negative urgency, but rather may serve as a risk factor.

Alcohol Use, Trait Anger, and Intimate Partner Aggression Perpetration in College Student Couples

Alcohol Use, Trait Anger, and Intimate Partner Aggression Perpetration in College Student Couples

Do couple drinking episodes lead to intimate partner aggression? An ecological momentary assessment study of same-sex and mixed-sex couples.

Alcohol use is an established risk factor for intimate partner aggression (IPA); however, few studies have considered whether couple drinking episodes increase the short-term likelihood of IPA episodes. The present ecological momentary assessment study considered the temporal effects of alcohol consumption on IPA perpetration and victimization within a sample of community couples at elevated risk of aggression. Mixed-sex (n = 191), same-sex male (n = 31), and same-sex female (n = 27) cohabiting couples (total N = 249; ages 21-35) made three independent, random reports for 30 consecutive days. Dyadic multilevel modeling was used to examine the impact of each partner's drinking episodes on the occurrence of verbal and physical perpetration and victimization events within the next 4 hr, using the actor-partner interdependence model. Actor and partner alcohol use increased the likelihood of conflict and likelihood of conflicts involving verbal perpetration and victimization within the next 4 hr; alcohol effects on physical aggression were weaker. Actor alcohol effects on IPA remained significant after the addition of several control variables; partner effects did not. The absence of Alcohol × Gender interaction effects suggests that alcohol effects on IPA do not depend on actor or partner gender or their combination. There are robust alcohol effects on the occurrence of verbal aggression perpetration and victimization episodes, with weak effects on physical aggression perpetration. Conflicts that include alcohol are not more likely to include aggression; rather, alcohol increases the likelihood of conflict occurring, with a proportion of those involving verbal aggression.

The effects of alcohol and marijuana co-use patterns on intimate partner aggression perpetration

Alcohol and marijuana are two of the most widely used substances in the U.S, with rates of alcohol and marijuana co-use increasing in recent years. Despite this increase, little is known about the effects of alcohol and marijuana co-use patterns (e.g., simultaneous, concurrent) on intimate partner aggression (IPA) perpetration. The purpose of the current study was to examine differences in IPA among simultaneous and concurrent alcohol and marijuana use groups and an alcohol-only group. Participants were 496 individuals (57% identifying as a woman) recruited nationally in April 2020 via Qualtrics Research Services who reported being in a current relationship and recently consuming alcohol. Individuals completed an online survey that included demographics, measures of COVID-19 stress, alcohol and marijuana use, and physical and psychological IPA perpetration. Based on survey responses, individuals were categorized as belonging to the alcohol use only group (n = 300), the concurrent alcohol and marijuana use group (n = 129), or the regular simultaneous alcohol and marijuana use group (n = 67). Due to inclusion criteria, there was no marijuana use only group. Individuals with regular simultaneous or concurrent alcohol and marijuana co-use reported more frequent physical and psychological IPA perpetration compared to those who only used alcohol. Neither physical nor psychological IPA perpetration frequency differed between individuals who reported regular simultaneous versus concurrent alcohol and marijuana co-use. Results suggest that alcohol and marijuana co-use in general, and not the specific pattern of use, is associated with an increased likelihood of IPA perpetration.

Socioeconomic Status and Intimate Partner Aggression: A Serial Mediation of Impulsivity and Anger.

Understanding the mechanisms underlying the association between lower socioeconomic status (SES) and Intimate Partner Aggression (IPA) is necessary for decreasing risk for IPA among lower-SES individuals. As limited control over one's external environment impacts individuals' ability to internally control their emotional states, the present study examined impulsivity and anger as serial mediators in the association from SES to IPA perpetration. Structural equation modeling analyses (N = 430 men, Mage = 24.66, 66.8% White) showed direct effects from lower SES to higher physical and sexual IPA. Additionally, there was a marginally significant indirect effect from SES to psychological IPA via higher impulsivity and anger. These findings may inform the development of interventions, showing that self-regulatory skills training may help lower psychological aggression. To address physical and sexual IPA, efforts that directly target the detriments of lower SES - via financial, housing, or educational support programs - may be indicated.

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.

Childhood Maltreatment, Personality Pathology, and Intimate Partner Aggression.

The goal of the current study was to examine the early childhood roots of adult personality pathology and intimate partner aggression in later life. Childhood maltreatment is associated with perpetration of intimate partner aggression (IPA) in adulthood, although the effect is generally only small to moderate in size. Childhood maltreatment is also linked with the Diagnostic and Statistical Manual of Mental Disorders (DSM) personality disorders (PDs) in adulthood, which in turn are correlated with IPA in adult romantic relationships. This suggests that one pathway by which childhood maltreatment leads to adult IPA is through maladaptive personality patterns. In the current analyses, data from 495 older, racially diverse adults and their romantic partners recruited from the St. Louis Personality and Aging Network (SPAN) study were used to examine whether childhood maltreatment may impact adult IPA through adult personality pathology. Findings from structural equation modeling demonstrated that for most of the 10 DSM-5 PD (Section II) constructs, there was a significant indirect effect from childhood maltreatment to IPA in later life through a latent variable of personality pathology. Our findings confirm that IPA does occur among romantic partners in later life, that it is robustly associated with personality pathology traits in later life, and that personality pathology in later life may have its roots in early neglect and maltreatment.

Intimate Partner Aggression During the COVID-19 Pandemic: Associations With Stress and Heavy Drinking.

This study aimed to test empirically whether (1) the local impact of the COVID-19 pandemic was associated with increases in intimate partner aggression (IPA) and heavy drinking, and (2) heavy drinking moderated the association between COVID-19 stress and IPA perpetration. Participants were 510 individuals (approximately 50% who endorsed a sexual or gender minority identity) recruited via Qualtrics Research Services in April 2020, during the height of shelter-in-place (SiP) restrictions across the United States. They completed a questionnaire battery that included measures of COVID-19 stressors, physical and psychological IPA perpetration, and heavy drinking. Rates of physical and psychological IPA perpetration significantly increased after implementation of SiP restrictions which aimed to mitigate the transmission of COVID-19. COVID-19 stress was significantly and positively associated with physical and psychological IPA perpetration; however, COVID-19 stress was positively associated with physical IPA perpetration among non-heavy drinking, but not heavy drinking, participants. Drawn from a large sample of participants of diverse sexual identities, findings tentatively implicate COVID-19 stress as a critical correlate of IPA perpetration and suggest that "low risk" individuals (i.e., non-heavy drinkers) should not be overlooked. These data provide preliminary support for the usefulness of public health polices and individual-level interventions that target stress, heavy drinking, and their antecedents.

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.

Intimate Partner Aggression During the Early Parenting Years: The Role of Dissatisfaction with Division of Labor and Childcare.

The high rates of intimate partner aggression (IPA) among new parents may be partly due to changes in couples' division of household labor and childcare, which disproportionately negatively impact women. This is the first study to examine the association between division of labor dissatisfaction and IPA perpetration across genders, while also examining whether such dissatisfaction is specifically associated with IPA during conflicts about division of labor issues. Quarterly for one year, 109 women and 94 men from 111 couples with a first-born child approximately 32 months of age at study commencement described each incident of IPA that occurred during the quarter, including conflict topics and number of aggressive acts perpetrated. Division of labor and childcare comprised the largest portion (30%) of IPA conflict topics. Division of labor dissatisfaction at child age 24 months was positively associated with women's, but not men's, IPA perpetration during conflicts about division of labor issues, but not other topics. A similar pattern of results emerged in the examination of division of childcare dissatisfaction and conflicts about childcare vs. other topics. The discovery that the impact of division of labor and childcare dissatisfaction on IPA perpetration is context- and gender-specific suggests that, among women, a history of dissatisfaction may impair appropriate conflict resolution skills specifically when addressing domains of dissatisfaction. These findings support prevention of women's IPA via nonaggressive strategies for addressing division of labor concerns and promotion of equal opportunities for women and men at home and in the workplace during the early parenting years.

Predicting Different Types of Intimate Partner Aggression Perpetration: The Roles of Problem Alcohol Use and Distress Tolerance.

Intimate partner aggression (IPA) victimization and substance use have been well established as risk factors for IPA perpetration (Leonard, 2005; Sprunger et al., 2015). Recent research has identified a negative association between distress tolerance and physical and psychological IPA perpetration, specifically in males in substance use treatment (Shorey et al., 2017). Research examining the interplay of problem substance use, distress tolerance, and other forms of IPA (i.e., sexual coercion, controlling behaviors) in non-clinical samples is limited. The present analysis aimed to examine the potential moderating effect of distress tolerance on problem alcohol use and four types of IPA perpetration (physical assault, psychological aggression, sexual coercion, and controlling behaviors) in a diverse, national sample (N = 323; 44.3% female; 52.9% sexual minority; age M = 33.61 years, SD = 8.71). Results showed that alcohol use and distress tolerance had differing influences on each IPA perpetration type. In line with hypotheses, distress tolerance significantly moderated the relationship between problem alcohol use and two forms of IPA (physical assault and controlling behaviors); this relationship was stronger for individuals with low levels of distress tolerance. Significant interaction effects did not emerge for psychological aggression or sexual coercion. Findings suggest that treatment strategies that focus specifically on increasing distress tolerance may be effective in reducing alcohol-facilitated IPA perpetration involving physical assault and controlling behaviors.

Personality disorders and intimate partner aggression: A replication and extension in older, married couples.

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

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.

Pathological personality, relationship satisfaction, and intimate partner aggression: Analyses using the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, alternative model of personality disorder traits.

Personality disorders (PDs) have been linked to lower levels of marital satisfaction and the perpetration of intimate partner aggression (IPA). Much of this work has used self-reports of PD symptoms conceptualized via the Diagnostic and Statistical Manual of Mental Disorder's (DSM) categorical approach. The current study adds to the literature by examining how marital satisfaction and IPA are associated with a dimensional assessment of PDs, specifically by conceptualizing PDs using the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Section III alternative model of personality disorder. By collecting data from both partners in a sample of newlywed couples, we also leverage PD trait agreement between (a) both partner's own self-reports (similarity), (b) self- and spouse report (accuracy), and (c) self and ratings of partner (perceptual similarity), to examine couple-level predictors of relationship well-being (i.e., satisfaction and psychological/physical IPA). Data were drawn from a sample of 101 newly married couples who participated in baseline and follow-up data collection over a period of 12 months. Actor-partner interdependence analyses revealed significant self-report actor and partner effects on marital satisfaction and psychological and physical IPA; for spouse report, actor effects were more consistent than partner reports. Agreement was moderate for both similarity and accuracy, but greater agreement was related to greater relationship satisfaction, particularly at later time points. Thus, although reports of elevated personality pathology are detrimental to marital functioning, spousal agreement may protect against these effects.

Emotion Dysregulation as a Moderator of the Association Between Relationship Dependency and Female-Perpetrated Dating Aggression.

The dependency-possessiveness model proposes that individuals who are highly dependent on their intimate partner and fear partner abandonment, particularly among those with emotion dysregulation problems, may be at heightened risk for intimate partner aggression (IPA) perpetration. Despite prior research establishing a link between relationship dependency and male IPA perpetration, it is unknown whether this association extends to female-perpetrated aggression, occurs in dating relationships, and is moderated by emotion dysregulation. Thus, the purpose of the current study was to investigate the association between relationship dependency and female-perpetrated dating aggression and determine if emotion dysregulation moderated this hypothesized relationship. Female undergraduate students (N = 119) completed measures assessing relationship dependency, emotion dysregulation, and female-perpetrated physical and psychological dating aggression as part of a larger study investigating the context of dating aggression episodes. Anxious attachment was significantly correlated with female-perpetrated psychological and physical dating aggression. Regression analyses indicated a significant interaction between the Spouse-Specific Dependency Scale [SSDS] Anxious Attachment subscale and emotion dysregulation predicting female-perpetrated physical dating aggression, suggesting moderation. There was a positive association between anxious attachment relationship dependency and female-perpetrated physical dating aggression at high levels of emotion dysregulation. A significant interaction was also found between the SSDS Emotional Dependency subscale and emotion dysregulation predicting female-perpetrated physical dating aggression, such that among those with low scores in emotion dysregulation, there was a positive relationship between emotional dependency and female-perpetrated physical dating aggression. Findings suggest that the ability to regulate emotions may play an important role in the association between relationship dependency and female-perpetrated dating aggression.

Trait Anger Moderates the Relation Between Facial Affect Recognition Ability and Perpetration of Male-to-Female Physical and Psychological Intimate Partner Aggression

Researchers have sought to identify deficits in affect recognition as a precipitating factor in intimate partner aggression (IPA) perpetration, but results from these studies have produced mixed findings. This may be due to the unlikelihood that deficits in affect recognition abilities would prompt perpetration of IPA without affective predispositions toward aggression, such as trait anger. The current study sought to examine the relation between negative affect recognition ability and men’s past perpetration of physical and psychological IPA across levels of trait anger. Heterosexual couples (N = 83) completed self-report measures regarding the frequency of male-to-female IPA perpetration within their relationship. Additionally, males completed measures of trait anger and were administered a facial affect recognition test. Decreased ability in decoding negative facial affect was associated with increased perpetration of physical and psychological IPA, but only for men high in trait anger. There was no relation between negative facial affect recognition ability and IPA perpetration at low levels of trait anger. Results from this study indicated that the highest rates of physical and psychological IPA perpetration within the sample were among those with co-occurring high trait anger and decreased ability to decode negative facial affect. Our findings suggest that perpetration of IPA is associated with an interaction of affective traits and deficits in social cognitive processing. Treatments aimed at reducing aggression and violence among intimate partners would benefit from improving affect recognition when high trait anger is present.

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).

Physical and Sexual Intimate Partner Aggression Among College Students: Examining the Roles of Cyber Intimate Partner Aggression and Alcohol Use.

Intimate partner aggression (IPA) is a serious and prevalent problem among college students. Two factors that may increase risk for in-person IPA are cyber IPA and alcohol use. This study examines the interaction between three types of cyber IPA (cyber psychological, stalking, and sexual IPA) and alcohol use in predicting in-person physical and sexual IPA perpetration. Participants were 268 undergraduate students, who participated in a mass screening at a large midwestern university. More than half of the sample reported perpetrating cyber IPA. A multivariate logistic regression model was used to examine study hypotheses. The R2 for physical IPA perpetration was .69 and the R2 for sexual IPA perpetration was .46. Cyber stalking IPA and alcohol interacted to predict physical IPA perpetration, such that the relationship between cyber stalking IPA and physical IPA perpetration was stronger among individuals who used more alcohol. Contrary to expectations, cyber IPA and alcohol did not interact to predict sexual IPA. However, consistent with hypotheses, cyber stalking IPA was positively associated with sexual IPA perpetration. The high prevalence of cyber IPA and its association with in-person IPA perpetration suggests that prevention programs targeting cyber IPA on college campuses may be warranted.

Aggression in the Context of Partner Threat: The Role of Trauma Exposure

Trauma-related biased perception of threat, typically defined in terms of physical danger or harm, is associated with intimate partner aggression perpetration. Yet, it is unclear if such threat (a) functionally motivates aggression and (b) includes diverse forms of threat. Theory and limited research suggest that threats of rejection/abandonment and social dominance may be two distinct functional precipitants of aggression among trauma-exposed individuals. Sixty-four heterosexual couples (N = 128 individuals) selected for elevated symptoms of posttraumatic stress disorder in either partner were observed during conflict discussions. Small correlations between men's and women's engagement in threats of rejection/abandonment and social dominance suggest that they reflect distinct types of threat. Partners' rejection/abandonment threats and social dominance threats were more strongly associated with engagement in aggression among men with a relatively high frequency of trauma exposure, compared to men with a low frequency of trauma exposure and all women. Women with a high, relative to low, frequency of trauma exposure behaved more aggressively in the context of their partners' social dominance threats; women's aggression was not associated with the severity of their partners' rejection/abandonment threats. Results align with research suggesting that highly traumatized men's misperceptions of threat may motivate their aggression, and indicate that aggression may also be used in the context of accurately detected threat. Integration of methods to alter contextual and individual factors influencing aggression perpetration may improve intervention outcomes. Compared to individually-based interventions, conjoint couple interventions may be better poised to address maladaptive contextual processes that contribute to relationship aggression perpetration.
