Do Drinking Episodes Contribute to Sexual Aggression Perpetration in College Men?

Objective:

Survey and experimental analog studies suggest that alcohol consumption contributes to perpetration of sexual aggression. However, few studies have considered the temporal association between naturally occurring episodes of drinking and subsequent sexual aggression. This daily report study was designed to examine whether alcohol consumption increases the odds of aggressive sexual activity within the next 4 hours.

Method:

First-year male college students (N = 427) completed daily online reports of drinking and sexual activity for up to 56 days. Multilevel modeling was used to determine whether drinking episodes increased the odds of the following outcomes occurring within 4 hours: (a) aggressive sex with a new partner, (b) non-aggressive sex with a new partner, (c) aggressive sex with a previous partner, and (d) non-aggressive sex with a previous partner.

Results:

Drinking episodes increased the odds of both aggressive and non-aggressive sex with a new partner. In contrast, drinking episodes did not predict aggression involving previous partners and decreased the odds of non-aggressive sex with a previous partner. Contrary to hypotheses, individual difference variables associated with propensity toward sexual aggression (sexual misperception, antisocial behavior, hostility toward women) did not interact with daily alcohol.

Conclusions:

The complex pattern of results is more consistent with situational as opposed to pharmacological effects of alcohol on sexual aggression and suggests that prevention efforts focus on drinking contexts known to facilitate sexual activity.

The Link Between Community-Based Violence and Intimate Partner Violence: The Effect of Crime and Male Aggression on Intimate Partner Violence Against Women

Below:  Analytical strategy for the study

Both intimate partner violence (IPV) and community violence are prevalent globally, and each is associated with serious health consequences. However, little is known about their potential links or the possible benefits of coordinated prevention strategies. Using aggregated data on community violence from the São Paulo State Security Department (INFOCRIM) merged with WHO multi-country study on women’s health and domestic violence data, random intercept models were created to assess the effect of crime on women’s probability of experiencing IPV. The association between IPV and male aggression (measured by women’s reports of their partner’s fights with other men) was examined using logistic regression models. We found little variation in the likelihood of male IPV perpetration related to neighborhood crime level but did find an increased likelihood of IPV experiences among women whose partners were involved in male-to-male violence. Emerging evidence on violence prevention has suggested some promising avenues for primary prevention that address common risk factors for both perpetration of IPV and male interpersonal violence. Strategies such as early identification and effective treatment of emotional disorders, alcohol abuse prevention and treatment, complex community-based interventions to change gender social norms and social marketing campaigns designed to modify social and cultural norms that support violence may work to prevent simultaneously male-on-male aggression and IPV. Future evaluations of these prevention strategies should simultaneously assess the impact of interventions on IPV and male interpersonal aggression.
