Prevention of partner violence by focusing on behaviors of both young males and females

Historically, the political context of partner physical aggression policy and research has focused on protection of physically victimized women and mandated interventions for male batterers. This emphasis is understandable when one considers the injuries and deaths of women by men. However, physical aggression against partners among teens is a very different phenomenon than battering. Intimate partner violence (IPV) in the form of physical aggression, the focus of this review, often starts in junior high school, and approximately 35% of male and female senior high school students report engaging in IPV. The specific trajectory of IPV varies by sample, but IPV appears to decrease in the late teens or early 20s. IPV is generally reported by both males and females, and not attributable to self-defense. IPV is significantly stable in couples who remain together, but stability appears lower if partners change. Given the importance of physical aggression by both males and females, prevention and early intervention programs need to address relationship factors, and targeted prevention and early intervention would be prudent with young high-risk couples. Decades of intervention programs for batterers have not proven very successful, and IPV appears easier to prevent than treat. Thus, emphasis on prevention of IPV seems both timely and promising. This review is intended for diverse audiences including educational administrators, policy makers, and researchers. It reviews issues such as who and when to target for IPV prevention programs, and it summarizes data relevant to these issues.

Item response theory analysis of intimate-partner violence in a community sample

The Revised Conflict Tactics Scale (CTS2; Straus, Hamby, Boney-McCoy, & Sugarman, 1996) is a widely used measure of physical, psychological, and sexual aggression as well as injury and negotiation between partners. In this study, we analyzed male-to-female and female-to-male physical aggression using data from 453 community couples. We used item-response theory (IRT) to assess the range and precision of physical aggression severity in the past year, as evaluated by the CTS2. Our analyses support a single dimension of physical aggression with quantitative, rather than qualitative, differentiation between minor and severe physical aggression items. Surprisingly, test information curves revealed that male perpetration and victimization items provided as much or more information as their counterpart female victimization and perpetration items over the same range of aggression severity. Finally, the data suggests that CTS2 items best assessed moderate-to-severe levels of physical aggression in the previous 12 months. However, virtually no information was assessed by male or female reports of perpetration or victimization items below or around the mean of aggression (i.e., theta; θ = 0). Suggestions for improved item coverage and implications for the assessment of aggression are discussed.

Stability, change, and informant variance in newlyweds' physical aggression: individual and dyadic processes

Individual and dyadic stability models of newlyweds' physical aggression were evaluated in a sample of 394 newlywed community couples recruited at engagement and followed for 2.5 years. Aggression in young couples was hypothesized to be a stable, enduring trait, consistent with a latent state-trait conceptualization. However, the findings indicated that aggression can more parsimoniously be conceptualized as a "somewhat stable" trait with strong short-term correlations that gradually decrease at increasing intervals. Aggression was significantly dyadic. Men and women's aggression were consistently associated with one another across time beginning at engagement, with little evidence that one person's aggression evoked aggression in the partner in the time intervals studied. Consistency in a person's reporting of aggression, not shared with the partner, was strongest for self-reports.

Do motivational interviewing behaviors predict reductions in partner aggression for men and women?

Motivational interviewing is a directive, non-confrontational intervention to promote behavior change. The current study examined therapist behaviors during a successful brief motivational interviewing intervention for physically aggressive college dating couples (Woodin & O'Leary, 2010). Forty-five minute motivational interviews with each partner were videotaped and coded using the Motivational Interviewing Treatment Integrity scale (MITI; Moyers, Martin, Manuel, & Miller, 2003). Hierarchical modeling analyses demonstrated that therapist behaviors consistent with motivational interviewing competency predicted significantly greater reductions in physical aggression perpetration following the intervention. Specifically, greater reflection to question ratios by the therapists predicted reductions in aggression for both men and women, greater percentages of open versus closed questions predicted aggression reductions for women, and there was a trend for greater levels of global therapist empathy to predict aggression reductions for women. These findings provide evidence that motivational interviewing seems to have an effect on behavior change through therapist behaviors consistent with the theoretical underpinnings of motivational interviewing.

A brief motivational intervention for physically aggressive dating couples

Motivational interviewing is a brief non-confrontational intervention designed to enhance motivation to reduce harmful behavior (Miller and Rollnick 2002). The purpose of this study was to examine the effectiveness of motivational interviewing as a targeted prevention approach for partner aggression in emerging adulthood. Participants were 50 college dating couples between 18 and 25 years old who reported at least one act of male-to-female physical aggression in their current relationships. After completing a 2-hour assessment session, half of all couples were randomly assigned to a 2-hour individualized motivational feedback session targeting physical aggression and risk factors for aggression. The remaining couples received minimal, non-motivational feedback. Follow-up surveys were conducted 3, 6, and 9 months later. Hierarchical linear modeling analyses indicated that, compared to the control condition, the motivational feedback intervention led to reductions in physical aggression and harmful alcohol use and to less acceptance of female psychological aggression and male psychological aggression (among women only). Lagged analyses indicated that changes in physical aggression were predicted by reductions in psychological aggression and by lower acceptance of both male and female psychological aggression. Reductions in physical aggression predicted lower anxiety and greater relationship investment and male relationship commitment over time. These findings suggest that a brief motivational intervention is a useful prevention approach for high-risk dating couples, with benefits to both individual and relationship functioning.

Prevalence and predictors of sexual aggression in dating relationships of adolescents and young adults

Dyadic influences among the diverse forms of aggression in dating relationships of adolescents and young adults have been reported in various studies. The goal of this research was to extend a dyadic model of physical aggression against partners to sexual aggression against partners. An urban sample of 4,052 adolescents and young adults of both genders, between 16 and 26 years old, was used. The percentage of male aggressors was significantly higher than that of the females (35.7% vs. 14.9%) and the percentage of victimization was higher for the women (25.1% vs.21.7%). Sexual aggression and sexual victimization was almost solely psychological in nature, that is, verbal coercion. As predicted by the dyadic model of physical aggression in dating relationships, sexual victimization was best predicted by sexual aggression of the individuals in this study both for males and females.

Descriptive epidemiology of intimate partner aggression in Ukraine

AIMS

Partner aggression is believed to be widespread in Eastern Europe although systematic evidence is sparse. Using data from the World Mental Health (WMH) survey in Ukraine, we present the first population-based findings on the descriptive epidemiology of partner aggression among married adults.

METHODS

Married men (n = 558) and women (n = 558) were interviewed with the WMH-Composite International Diagnostic Interview (WMH-CIDI) module assessing aggression in the marriage. Risk factors included demographic characteristics, witnessing parental aggression, early onset and adult episodes of DSM-IV psychiatric and alcohol disorders, and marital problem severity.

RESULTS

More women than men reported aggression by their spouse in the past year (12.7 vs. 5.8%) or ever in the marriage (20.1 vs. 8.6%), while ~11 and 19% of both sexes behaved aggressively against their spouse in these time periods. Among men, the unique risk factors for behaving aggressively were being married once, witnessing parental violence, early onset alcohol abuse, and intermittent explosive disorders (IED); the risk factors for reporting that their wives were aggressive were early onset alcohol abuse, IED and marital problems. Among women, the risk factors for behaving aggressively were younger age, unemployment, living in a rural area, early onset alcohol abuse, mood/anxiety disorders, and marital problems; the risk factors for reporting that their husbands behaved aggressively were younger age, early onset alcohol abuse, and marital problems.

CONCLUSIONS

Partner aggression is a significant public health issue in Ukraine predicted by alcohol abuse and IED before and after age 20 for men and women.

Alcohol and intimate partner violence: a meta-analytic review

The link between alcohol use/abuse and partner violence attracted increasing research attention in the past decade. Some studies reported a null or weak association between alcohol use and intimate partner violence, whereas other studies reported a moderate or large association. Using a meta-analytic approach, the link between alcohol use/abuse and male-to-female partner violence as well as female-to-male partner violence was examined herein. The results indicate that there is a small to moderate effect size for the association between alcohol use/abuse and male-to-female partner violence and a small effect size for the association between alcohol use/abuse and female-to-male partner violence. For men only, several moderators were also examined and the magnitude of the effect sizes varied significantly as a function of the type of sample and type of alcohol measure selected. Specifically, there was a larger association of alcohol and aggression in clinical versus non-clinical samples and when measures assessed more severe alcohol problems.

Gender differences in dating aggression among multiethnic high school students

PURPOSE

(1) To assess prevalence of physical dating aggression and victimization among high school students; (2) to assess prevalence of mutual and exclusive aggression; (3) to determine whether aggression differs across ethnic groups and relationship type; and (4) to ascertain the likelihood of injury and breakup in individuals who reported that they were the recipients of physical aggression.

METHODS

Students (N = 2363) from seven multiethnic high schools participated. Because males in high school date females younger than they and the reverse for females, and because males and females may underreport aggression, only within gender comparisons were conducted.

RESULTS

More females reported engaging in physical aggression (40%) than reported being victims of aggression (30%). Fewer males reported engaging in physical aggression (24%) than reported being victims of physical aggression (31%). If physical aggression occurred, typically both partners were aggressive. For females, exclusive engagement in physical aggression (perpetration) was reported at higher rates than exclusively being the recipient of physical aggression (victimization) and vice versa for males. Dating aggression was less prevalent among male Asian students than other ethnic groups. Engaged males and females reported the highest rates of physical aggression. Injury was reported by over 25% of males and females who reported being the recipients of physical aggression.

CONCLUSIONS

Dating aggression intervention programs should address physical aggression of both males and females. Because approximately 30% of the high school males and females reported being the recipients of physical aggression by their partners, primary prevention efforts should occur before high school.

Multivariate models of men's and women's partner aggression

This exploratory study was designed to address how multiple factors drawn from varying focal models and ecological levels of influence might operate relative to each other to predict partner aggression, using data from 453 representatively sampled couples. The resulting cross-validated models predicted approximately 50% of the variance in men's and women's partner aggression. The 3 strongest direct predictors of partner aggression for men and women were dominance/jealousy, marital adjustment, and partner responsibility attributions. Three additional direct paths to aggression for men were exposure to family-of-origin aggression, anger expression, and perceived social support. The 1 additional direct path for women was a history of their own aggression as a child or teenager. Implications for more integrative theories and intervention are discussed.

Females' reasons for their physical aggression in dating relationships

Approximately 32% of dating college females reported that they engaged in physical aggression against their partners and that they engaged in acts of physical aggression more often than their male partners engaged in aggression against them. However, the females also reported that their male partners attempted to force them to engage in oral sex more often than the females engaged in such coercive behavior. Based on both open-ended and closed responses, the primary reasons given for engaging in physical aggression were anger at the partner and poor communication. Females who reported physical aggression in their relationships were less satisfied with their relationships, and both psychological and physical aggression were negatively correlated with positive feelings about the partners.

Physical and psychological aggression in dating relationships in Spanish university students

The presence of violent behaviors of a psychological and physical nature in dating relations was analyzed in a sample of Spanish university students between 18 and 27 years of age. The results indicate a high prevalence of both kinds of aggression in interpersonal relationships, revealing important typology differences between the sexes. Violent psychological behaviors (characterized by the presence of verbal aggression and coercive and jealous behaviors) and physical aggression were significantly higher in women, though the consequences of physical aggression were worse for the women's health. The implications of the results and their possible relation with more severe violent acts in more stable, emotional relationships are discussed.

Agreement about acts of aggression in marriage

Psychological and Physical Aggression scales met internal consistency and agreement standards on the Revised Conflict Tactics Scales (CTS2) in a randomly recruited sample of 453 married community couples with children. Moreover, partners agreed on the extent of psychological and physical aggression as much or more than they did on CTS2 Negotiation scale and positive behaviors assessed on the Dyadic Adjustment Scale. On the other hand, the CTS2 Sexual Coercion and Injury scales had much lower internal consistencies as measured by Cronbach's alpha, and agreement was generally very low. Men and women reported less abusive behavior and consequent injury than partners reported about them. Correction factors were provided for prevalence estimates of abusive behavior and injury when only perpetrator reports were available.

Reaction time and item presentation factors in the self-report of partner aggression

The Conflict Tactics Scales (CTS) have used different formats intended to maximize the accuracy and disclosure of relationship aggression. The original CTS presented items in a hierarchical order, seeking to establish a "context of legitimation." The CTS2 presented items in an interspersed order to reduce denial response sets. The current study used computer administration of the CTS and sought to determine whether the two presentation formats described above result in differing self-reports of aggression and to explore possible causes of such an effect, such as differences in reaction time. Results indicated that item order did not significantly affect reports of aggression, but increasing participants' reaction times by experimental manipulation of the minimum item display duration resulted in increased self-reports of aggression.

How do I tell thee? Voice, pen, or computer key

In this issue, the previous two articles by Hamby and colleagues and Vega and O'Leary are concerned with whether the method of administration and format of the Conflict Tactics Scale influence participant responses. Because they examine different aspects of the same measure, I was asked to conclude the issue by writing a brief summary and integration of the two articles.

Partner aggression severity as a risk marker for male and female violence recidivism

Pretreatment aggression severity was examined as a risk marker for recidivism in the treatment of partner aggression. Intact married couples experiencing husband-to-wife partner aggression were recruited from the community and participated in either conjoint group treatment or gender-specific group treatment. Elevated levels of husband and wife physical aggression and wife psychological aggression before treatment predicted the continuation and severity of physical aggression by both spouses during treatment and in the following year, with no significant differences across treatment formats. These results indicate that high levels of psychological and physical aggression signify a poor prognosis for both conjoint and gender-specific group treatment programs, suggesting the need for interventions of greater intensity, duration, and/or focus for individuals highest in psychological and physical aggression.

Partner aggression and problem drinking across the lifespan: how much do they decline?

Cross-sectional analyses from nationally-representative samples demonstrate significant age-related trends in partner aggression and problem drinking. Both behaviors are most prevalent in the early to mid-twenties and increasingly less common thereafter. Aggregate associations based on percentage of individuals displaying the behavior in each age range are dramatically stronger than those found when correlating individuals' ages and behavior. Multilevel modeling demonstrates that group-level effects do not mask associations found at the level of the individual for either problem drinking or partner aggression. An analysis of recent abstracts from psychology journals showed that issues of aggregate and individual data are rarely if ever discussed, and even well-known statistics books in psychology rarely discuss such issues. The interpretation of aggregate data will become increasing important as psychologists themselves, and in collaboration with epidemiologists and sociologists, have access to large data sets that allow for data aggregation. Both aggregate and individual analyses are valid, although they provide answers to different questions. Individual analyses are necessary for predicting individual behavior; aggregate analyses are useful in policy planning for large scale prevention and intervention. Strengths and limitations of cross-sectional community samples and aggregate data are also discussed.

Effectiveness of anger treatments for specific anger problems: a meta-analytic review

This meta-analytic review analyzed the effects of anger treatment on various aspects of anger with 65% of studies not previously reviewed. To improve on past reviews, this review included only noninstitutionalized adults with demonstrable anger as determined by standardized measures. The studies were compiled from a computer search of published and unpublished anger treatment studies conducted between January 1980 and August 2002. The search resulted in 23 studies containing one or more treatment groups and a control group, with effect sizes derived for each anger problem within each treatment category. The meta-analysis resulted in medium to large effect sizes across therapies. Further analyses of effect sizes within treatment groups by the kind of anger reported support the implementation of cognitive therapies for driving anger, anger suppression, and trait anger. In contrast, relaxation is recommended in cases of state anger. Other implications for treatment and future research directions are discussed, including a special need for research with treatment-seeking individuals and clinical populations.

Physical and psychological partner aggression across a decade: a growth curve analysis

The course of physical and psychological partner aggression was investigated over a decade in 203 wives from Suffolk County, New York. Wives reported on their own and on their partners' aggression at one month before marriage and 6, 18, 30, and 120 months after marriage. This follow-up is the longest period over which partner aggression has been examined. Prevalence rates of wife's report of wife- and husband-perpetrated physical aggression were 48% and 35% at premarriage, and 13% and 10% ten years later. Using HLM, husband- and wife-perpetrated physical aggression were found to decrease on average approximately one act of aggression per month, regardless of severity and even when controlling for changes in marital satisfaction. There was no significant pattern of change in psychological aggression. These findings are consistent with cross-sectional analyses, and suggest that physical partner aggression decreases in community samples of couples.

The association between alcohol use and intimate partner violence: linear effect, threshold effect, or both?

The present study examined whether the association between alcohol and male-to-female intimate partner violence (IPV) is most meaningfully described as a linear relationship, a threshold effect, or both. Men in two nationally representative samples, the National Family Violence Survey (NFVS) and the National Survey of Families and Households (NSFH), were divided into similar drinking groups based on quantity and frequency of alcohol consumption. Analyses of the association between IPV and drinking category revealed that although linear associations between drinking classification and IPV were significant in both samples, the associated effect sizes were very small. Further, only heavy drinkers and binge drinkers were major contributors to the significant chi-squares. Overall, the results revealed both linear and threshold effects, and suggest that distinctions among drinking patterns may be more important than incremental increases in quantity or frequency in conceptualizing alcohol as a risk factor for IPV.
