Impelling and inhibitory forces in aggression: sex-of-target and relationship effects

The finding of symmetry in intimate partner aggression is now generally accepted, but the convergence of male and female rates in these relationships remains unexplained. From qualitative analysis of male and female focus group discussions, we identified factors believed to influence the expression of aggression toward targets differing in sex and degree of intimacy. These factors were then used to construct a questionnaire in which 355 respondents indicated the applicability of the items to conflicts with a partner, a same-sex friend, and an opposite-sex friend. Principal component analysis revealed a clear two-factor structure of impelling forces (tending to provoke or initiate aggression) and inhibitory forces (tending to suppress or diminish the likelihood of aggression). Participants' scores on scales derived from these two factors were used in the subsequent analyses. Men reported lower inhibition and greater impulsion toward same-sex friends than to female friends and partners, who did not differ significantly from one another. Women showed lower inhibition to male targets, regardless of relationship, than to a female target. However, women rated their male partners as significantly higher on impelling forces than their male friends, who in turn were rated significantly higher than female friends. The results are broadly consistent with a sex-of-target effect corresponding to a chivalry norm held by both sexes that inhibits the expression of aggression toward women. The reasons why women are especially impelled to aggression by intimate partners are explored. Disaggregating the dynamics of interpersonal conflict into impelling and inhibitory components may prove useful in understanding and treating dispute escalation and resolution.     

The sexual assault of undergraduate women at historically Black colleges and universities (HBCUs)

Although research has shown that undergraduate women are at high risk for experiencing sexual assault, little research has been conducted with undergraduate women who are attending a historically Black college or university (HBCU). The purpose of this research is to document the prevalence of different types of sexual assault among undergraduate women at HBCUs and make comparisons to data collected from undergraduate women at non-HBCUs. Data on sexual assault victimization were collected from 3,951 undergraduate women at HBCUs using a cross-sectional, web-based survey. These data are compared to data collected from 5,446 undergraduate women at non-HBCUs using the same research methods. Findings indicate that approximately 9.7% of undergraduate women at HBCUs report experiencing a completed sexual assault since entering college. This rate is considerably lower than the comparable rate obtained from undergraduate women at non-HBCUs (13.7%). This difference seems to be associated with differences in alcohol-use frequency. Perhaps undergraduate women at HBCUs drink alcohol much less frequently and are thus less likely to be sexually assaulted when they are incapacitated and unable to provide consent. Alcohol use frequency, while controlling for other factors, seems to have an independent association with the likelihood of an undergraduate woman being sexually assaulted. Implications for the creation and delivery of sexual assault risk reduction and prevention policies and programs are discussed.
