  1. Gender Differences In The Relation Of • Dyadic Types Of Partner Violence To Depression • Among University Students In 15 Nations • Murray A. Straus • Family Research Laboratory, University of New Hampshire • Durham, NH 03824 603-862-2594 murray.straus@unh.edu • Website: http://pubpages.unh.edu/~mas2 • Zeev Winstok • Center for the Study of Society, University of Haifa, • Mount Carmel, Haifa 31905, Israel • zeevwin@research.haifa.ac.il • Presented at the Society For the Study Of Social Problems annual meeting, New York 8 August 2013. • This is one of a series reporting results of the International Parenting Study directed by Angele Fauchier (angele.fauchier@unh.edu), and the Dyadic Types Research Program. Papers on these and related topics can be downloaded from http://pubpages.unh.edu/~mas2 • The work was partly supported by National Institute of Mental Health grant T32MH15161, the University of New Hampshire. .

  2. Questions To Be Addressed • What percent of university student couples in 15 nations experienced violence in their relationships in the previous 12 months? • Of those who experienced violence, what percent were in each of three “Dyadic Types” (DTs): • Male-Only, Female-Only, Both-Assaulted? • 3. What is the relationship between violence in a relationship and depression and does this vary depending on: • A. Whether the partner was the victim or the aggressor, or both victim and aggressor? • B. Whether it is the male or female partner? • Results are somewhat surprising • 4. What is a plausible theory to explain them? • 5. What are the implications for • Theories to explain PV? • Methodology for research on PV? • Efforts to prevent and treat PV?

  3. The International Parenting Study 15 Nations, 11,408 university students • Analyses control for variables such as: • Age of student • Socially desirable responding • Parent’s education

  4. Measures Partner violence: Short form of the Revised Conflict Tactics Scales Straus, M. A., & Douglas, E. M. (2004). A short form of the Revised Conflict Tactics Scales, and typologies for seventy and mutuality. Violence and Victims, 19, 507-520. Cases will be analyzed by comparing “Dyadic Types” of partner violence Depression: Major Depression Inventory Olsen, L. R., Jensen, D. V., Noerholm, V., Martiny, K., & Bech, P. (2003). The internal and external validity of the Major Depression Inventory in measuring depressive states. Psychological Medicine, 33, 351-356.

  5. Data Analysis • Analysis of covariance • Controlled for: • Education of father • Education of mother (are the results just a reflection of SES? • Misbehavior as a child (are results just a continuation of a long –standing pattern) • Corporal punishment by father As above • Corporal punishment by mother As above • Age of student at time of study (because older persons have lower crime rates • Limited Disclosure scale (do the results just reflect that willingness to disclose one type of socially undesirable behavior is associated with willingness to disclose other types) • Nation in which data was collected There are important differences between nations in the prevalence of crime. National differences in crime, include DT are analyzed elsewhere (cite??). The focus of this study is whether there are effects of DT that are in addition to the national context effects.

  6. Dyadic Types (DTs) • Everyone Agrees On The Need To Take Into Account The Behavior Of Both Partners To Deal With Relationship Issues. But Few Do • DTs are a practical method of doing taking the behavior of both partners into account • Three DTs: * Male Partner Only * Female Partner Only • * Both partners engage in the behavior • Practical because • DTs obtained by just cross tabulating the behavior of the male partner by that of the female partner • If the behavior is an interaction in which both participated, such as violence, data obtained from just one of the partners, has the same validity (or lack of) as when both partners

  7. Dyadic Assault Types For Dating Relationships Among 11,408 University Students in 15 Nations - Any Assault Q 1. What percent of university student couples in 15 nations experienced violence in their relationships in previous 12 months? Prevalence Men 14% Women 18% Q 2 Of those who experienced violence, what percent were in each of three “Dyadic Types” (DTs): 47% 43% 10% Straus, M. A., & Winstok, Z. (2013). Gender Differences in the Relation Of Dyadic Types Of Partner Violence To Depression Among University students in 15 nations. Paper presented at the Society For The Study Of Social Problems Annual Meeting, New York.

  8. Are These Percentages Unique To This Student Sample? U.S. National Comorbidity Study (N=8,098)* • Predominant Pattern Is • Both-Violent • Male-Only and Female-Only about same % • Same pattern as in current study and in more than 50 studies** which found: % * Kessler, R. C., Molnar, B. E., Feurer, I. D., & Appelbaum, M. (2001). Patterns and mental health predictors of domestic violence in the United States: Results from the National Comorbidity Survey. International Journal Of Law And Psychiatry, 24(4-5), 487-508.

  9. - 48 studies Ada[ted from Langhinrichsen-Rohling, J., Selwyn, C., & Rohling, M. L. (2012). Rates of Bidirectional Versus Unidirectional Intimate Partner Violence Across Samples, Sexual Orientations, and Race/Ethnicities: A Comprehensive Review. Partner Abuse, 3(2), 199-230. doi: 10.1891/1946-6560.3.2.199

  10. Percentages are similar when based on reports by male students

  11. Is the High Percent of Women Who Assault Self-defense? • Studies on who hit first found it was female partner half the cases • Hamberger, 1997 77% • Bland & Orn ,1986 73% • Straus, 2012 61% • Stets [, 1990 #4608] 58% • DeMaris ,1992 49% • Capaldi[, 2007 #11544] 46%  the median %- • Gryl, Stith, & Bird ,1991 41% • Saunders ,1986 40% • Fiebert, Gonzalez, 1997 32% • Molidor& Tolman, ,1998 30% • O’Keefe ,1997 21% • 9 Studies which asked women whether it was in self-defense: • Median = 19%, range:5 to 47% • None of the studies found that a majority of women acted in self-defense • Almost half of the eleven comparisons found a higher percent of men than women acting in self-defense

  12. Question 3. What is the relationship between violence in a relationship and depression and does this vary depending on: • A. Whether the partner was the victim or the aggressor, or both victim and aggressor? • B. Whether it is the male or female partner?

  13. Relation of Dyadic Types Of Partner Violence To Depression Dating Relationships Of University Students In 15 Nations (N=11,408) Women Men • No Violence: Women higher in depression than men • Sole Perpetrator: Male perpetrators higher in depression than female • Sole Victim: Women victims higher in depression than male victims • Both Assault, i.e. both are victims and also perpetrators: Men higher in depression

  14. Relation of Dyadic Types Of Partner Violence To Depression Dating Relationships Of University Students In 15 Nations (N=11,408) • When men assault, either as sole perpetrator or both, male depression higher. Suggests either depression as a cause or male guilt, or both • Women have highest depression when they are the sole victims of assault or both a victim and a perpetrator • Gender Difference In link between PV and depression: Increase in depression is greater for men than women , except when men are the sole victims Women Men

  15. Summary • Both-Assault Dyadic Type • The most prevalent Dyadic Type of partner violence • Most closely associated with depression– not surprising • Both most harmful is consistent with other studies, including studies of harmful effects for children • Male-Only and Female-Only Dyadic Types • Also associated with more mental health problems than among non-violent couples, but less so than the Both Assault DT. • Comparing the sole perpetrator with being the sole victim • Men are higher in depression when they are the sole perpetratorsthan when they are the sole victims • Women are higher in depression when they are the sole victims than when they are the sole perpetrators • What might explain these unexpected result?

  16. Question 4 . What is a plausible theory to explain the results? • The difference between men and women in the relation of partner violence to depression reflects differences in culturally and biologically based gender roles • Two relevant role differences are Greater saliency and importance of • Status maintenance and enhancement for men • Safety for women • An underlying principle is that threat to central aspects of the self are associated with an increased probability of depression • For men, lost of status if their violence becomes known is a bigger threat than lack of safety when they are victim of violence by their partner • For women, lack of safety when they are attacked by their partner is bigger threat than loss of status if their violence becomes known.

  17. Paper On The Theory In Preparation • Will explain the basis for believing the assumptions are valid., for example the link between threat to the self and depression • * Will provide specification of the theoretically based relationships • Winstok and Straus, “Gender Differences In Salience Of Status Enhancement and Safety In Relationships And Gender Differences In the Link Between Partner Violence and Depression

  18. Q 5 Implications For Theory, Methods, And Practice Theory Explanations of the causes or the effects of PV need to take into account that studies world-wide found that Male-Only: about 25% Female-Only: about 25% Both-Assault: about 50% of couples Self-defense explains female violence only 10-20% of the time Method DTs need to be identify in all research on partner violence Necessary and practical to obtain data on both partners Can be done even when only one partner is the research participant

  19. Implications (continued) • Practice • Because about half of all partner violence cases are in the “Both-Assault” type, including women seeking help from shelters: • Service providers need to determine which DT applies to a particular client and why • Determining the Dyadic type is second only to determining safety
