2. ID412 DOMINANCE AND SYMMETRY IN PARTNER VIOLENCE BY MALE AND FEMALE UNIVERSITY STUDENTS IN 32 NATIONS SOME RESULTS FROM THE INTERNATIONAL DATING VIOLENCE STUDY Murray A. Straus University Of New Hampshire

3. ID413 THE ISSUES 1. Is partner violence primarily perpetrated by men, as compared to women, and as compared to both partners engaging in violence? 2. To what extent is dominance by the male partner associated with partner violence, as compared to dominance by the female partner? In short is the issue one of male dominance or one of inequality between partners?  The answers to these questions can have profound implications for prevention and treatment of partner violence.

6. ID416 OBJECTIVE 1: PREVALENCE OF “MALE-ONLY” “FEMALE-ONLY,” AND “BOTH VIOLENT” TYPES OF PHYSICAL ASSAULT THE REVISED CONFLICT TACTICS SCALES (CTS2) Minor Physical Assault: Threw something at partner that could hurt Twisted my partner’s arm or hair Pushed or shoved my partner Grabbed my partner Slapped my partner Severe Physical Assault: Punched or hit my partner with something that could hurt Choked my partner Slammed my partner against a wall Beat up my partner Burned or scalded my partner Kicked my partner Alpha coefficient of reliability =.88

10. ID4110 CONCLUSIONS ABOUT PREVALENCE AND MUTUALITY OF PHYSICAL ASSAULT  Students in some national settings have lower rates than elsewhere, but the rates are high even in low ranking countries such as Sweden and Portugal  About a third of the violence is “Severe” among these students, as in many other studies, and a substantial percent are injured  Throughout the world, women students physically assault dating partners at about the same rate as men  Male-Only violence is rare among university student couples throughout the world  When there is violence, predominant pattern is Both-Violent  These assaults are a threat to the physical and mental health of students

11. ID4111 WOMEN HITTING MEN IS A SERIOUS PROBLEM EVEN "HARMLESS" ASSAULTS BY WOMEN ARE SERIOUS AND NEED TO BE A FOCUS OF PREVENTION AND TREATMENT  DANGEROUS FOR WOMEN  HARMFUL TO CHILDREN  A CRIME  MORALLY WRONG  HELPS PERPETUATE THE IMPLICIT CULTURAL NORMS TOLERATING FAMILY VIOLENCE ALSO  A SUBSTANTIAL NUMBER ARE NOT PHYSICALLY HARMLESS * A THIRD OF ALL DOMESTIC HOMICIDES ARE BY WOMEN * 10 TO 40% OF PARTNER VIOLENCE INJURIES ARE INFLICTED BY WOMEN

12. ID4112 F = 14.8*** 7,597 WOMEN. CONTROLLING FOR SOCIAL DESIRABILITY THE “HARMLESS SLAP” BY A WOMEN IS A THREAT TO HER HEALTH 52% of the women in the IDVS approved of slapping a husband’s face. Those who approved were much more likely to have been severely assaulted and injured by their partner

13. ID4113 OBJECTIVE 2: TEST THE HYPOTHESIS THAT DOMINANCE BY ONE PARTNER IS ASSOCIATED WITH AN INCREASED PROBABILITY OF ALL THREE TYPES PARTNER VIOLENCE METHOD: Multinomial logistic regression INDEPENDENT VARIABLE: Dominance scale score (Personal and Relationships Profile (PRP), Straus et al. 1999) Example items: “I generally have the final say when my partner and I disagree” “My partner needs to remember that I am in charge.” Response categories: 1 = Strongly Disagree, 2 = Disagree, 3 = Agree, 4 = Strongly Agree. Scale score: mean of the nine items. Range of scores to 4 A actual range: 1 to 3.96 (mean = 1 95, SD = 0.39).

22. ID4122 FIVE OTHER STUDIES IN KOREA, HONG KONG, MEXICO, AND USA ALSO FIND THAT DOMINANCE BY EITHER A MALE OR FEMALE PARTNER INCREASES THE PROBABILITY OF ASSAULT BY BOTH WOMEN AND MEN INEQUALITY INCREASES THE PROBABILITY OF VIOLENCE, NO MATTER WHO IS DOMINANT

23. ID4123

24. ID4124 DOMINANCE IS ONLY ONE OF MANY CAUSES OF PARTNER VIOLENCE AND NOT NECESSARILY THE MOST IMPORTANT SOME OTHER CAUSES FOR WHICH THERE IS EVIDENCE: Alcohol abuse Antisocial and Borderline personality Lack of social skills Impulsivity Stress Depression Next two slides Implicit cultural norms that tolerate low-level violence Corporal punishment

25. ID4125 A LARGE PERCENT OF STUDENTS AGREE THERE ARE SITUATIONS WHEN THEY WOULD APPROVE OF SLAPPING A PARTNERS FACE THE PERCENT APPROVING A WIFE SLAPPING HER HUSBAND IS ALWAYS HIGHER THAN FOR A HUSBAND SLAPPING THE PERCENT OF WOMEN WHO APPROVE OF A HUSBAND SLAPPING HIS WIFE IS SIMILAR TO THE PERCENT FOR MEN THESE RESULTS PARALLEL W.H.O.

29. ID4129 POLICY AND PROGRAM IMPLICATIONS ABOUT DATING VIOLENCE More recognition needed that:  Dating partner violence is about three times more prevalent than violence between married couples  It is a serious mental and physical health problem  More prevention & treatment effort for students is needed

30. ID4130 IMPLICATIONS FOR PREVENTION AND TREATMENT  Victim services should continue to give priority to women because women are injured more, physically, psychologically, & economically  Time for major changes in prevention and offender treatment  Give equal attention to prevention of partner violence by women and treatment of female offenders because:  Women are half the offenders. Ignoring this cripples prevention and treatment efforts  Prevention of female violence needed to protect women because violence by women is a major contributor to victimization of women. Therefore efforts to end partner violence by women will contribute to protecting women  Abandon the single-cause fallacy of male-dominance and attend to:  Dominance by either partner  The multiplicity of other factors, including the primordial violence spanking children  The similarity of causes of violence by men and women

31. ID4131 IT IS TIME TO MAKE THE FOCUS Ending All Family violence Starting with spanking children Including violence BY women, not just violence against women ONLY THEN WILL WOMEN, AS WELL AS ALL OTHER HUMAN BEINGS, BE SAFE IN THEIR OWN HOMES

34. ID4134 PURPORTED DEFECTS OF THE STUDY MANY REAL LIMITATIONS, BUT NONE OF THOSE ALLEGED See the limitations section of the paper available on http://pubpages.unh.edu/~mas2.) DEFECT 1: TWO THIRDS OF SAMPLE ARE WOMEN AND THAT EXPLAINS MORE VIOLENCE BY WOMEN It does not because we computed the percent of the women who hit a partner and the percent of the men who hit a partner. DEFECT 2: RESULTS ARE CONTRADICTED BY CASES WE SEE They are different, but not contradicted. What is contradicted is the belief that cases seen in shelters and by police are typical. They are the tip of the iceberg, are very important, but not typical. The typical case is mutual violence. Shelters or police are almost never involved, even though it causes serious psychological injury and sometimes physical injury to the partners and to children in the home. DEFECT 3: RESULTS ARE CONTRADICTED BY FBI AND NATIONAL CRIME SURVEY AND OTHER POLICE STATISTICS Crime statistics, of course, represent only the type of cases that get involved in the legal system. Police call data is, at most 1/80 th of the annual cases. They are very important and should have priority for services. But they are far far from typical and do not contradict the findings from over 200 studies showing about equal rates and a predominance of mutual violence..

35. ID4135 DEFECT 4: MEASURED ONLY ACTS OF VIOLENCE, NOT THE CONSEQUENCES The study measured several consequences, including injury and depression and found that male victims were often injured or depressed. Attacks by women account for about a third of all physical injuries from partner violence, including a third of those that are fatal. Male partners of violent women have increased rates of depression, but the increase is not as great as for female victims. Although women cause less injury, they cause a lot and the victims deserve help. DEFECT 5: DID NOT TAKE INTO ACCOUNT THE “FACT” THAT MOST VIOLENCE BY WOMEN IS SELF-DEFENSE The studies actually show that only a small percent of partner violence (5% to 15%) by either men or women is in self-defense. A large percent by both men and women is retaliation for being hit by a partner. This is one of the reasons mutual violence is predominant. DEFECT 6: DOES NOT RECOGNIZE THAT MOST VIOLENCE BY WOMEN IS TO END DOMINATION AND OPPRESSION Those who claim this have not read the study because that was one of the main issues. We did find that domination by a partner is ONE of the important causes, but only one of many. We found that domination by either the male or female partner was related to an increased likelihood of violence. In addition, violence is not a moral or legal way to end domination by either a male or female partner.
