Coercive sexual behavior exists at alarming rates on college campuses. Researchers attempting to identify factors related to sexual coercion have primarily investigated either the coercing college male or the coerced college female, independent of relationship factors. The present study investigated the prevalence of verbal sexual coercion, the beliefs and attitudes of sexually coercive and noncoercive men, and the differences in affective states between groups and at different stages of relationship development. Undergraduate students were grouped on the basis of their self-reported sexual experience history as being sexually inexperienced, having had consensual sexual relationships only, or having had coercive sexual relationships. Also, subjects who reported having been sexually experienced were asked to rate the nature of their relationship to their sexual partner. Subjects completed measures referring to sexual attitudes, sexual arousal patterns, and the emotional components of a sexual encounter. Analyses indicated that 42% of the males in the sample had engaged in verbal sexual coercion. Differences on the measures were found between the sexual experience groups and the relationship type subgroups. Results are discussed in the context of the situational model, in which the coercive male plays an active role in shaping his environment.
This study's purpose was to assess resistance to sexual aggression, from kissing/fondling to intercourse; to test the relative efficacy of three theoretical models (Victim Precipitation, Social Control, and Situational Blame) for predicting resistance to acquaintance rape. Seventy-five percent of the 206 university students reported vicitimization. Average time since victimization was 2.03 years. Sixty-eight percent of victims successfully resisted their most severe victimization attempt. Four situational factors predicted resistance: isolation of incident site, previous victim-offender relationship, previous victim-offender sexual intimacy, and clarity of victim nonconsent. Two personality variables, the California Personality Inventory scales of dominance and social presence, distinguished successful from unsuccessful resisters. Attitudinal measures were not statistically significant.
The dating attitudes and behaviors of Australian youth were studied. Both sexual and affectional attitudes and behaviors were examined. The influence of the following factors was assessed: stages of dating, age, socioeconomic status, church attendance, and type of school attended. Psychosexual and psychoaffectional scales were used to measure dating orientation. Findings suggest that factors influencing sexual orientation are the stage of dating, age, church attendance, and type of school attended. Factors influencing psychoaffectional orientation are stage of dating, church attendance, and type of school attended. One important verification to emerge from the research was that the psychosexual and psychoaffectional orientations were not opposite poles of a single continuum but were totally independent dimensions. It is possible to score high or low on both dimensions depending on past experience, present attitudes and the nature of the present relationship. Further, the male psychoaffectional orientation was not markedly different from the female orientation, as has been previously suggested.

Research shows that people engage in "risky" sex with "safe" partners and in "safer" sex with "riskier" partners. How is the determination of "risky" or "safe" status made? Factorial survey methodology was used to randomly construct descriptions of romantic partners based on attractive and/or risky characteristics. Respondents evaluated 20 descriptions for attractiveness, health risk, likelihood of going on a date, likelihood of unprotected sex, and likelihood of STD/HIV infection. Respondents were most attracted to and perceived the least risk from attractive descriptions and were least attracted to and perceived the most risk from the risky descriptions. The differences between the "conflicting information" descriptions are attributable to a primacy effect: descriptions that began with attractiveness information but end with risk information were evaluated more positively than those that began with risk and ended with attractive information.
The current study examined the joint contributions of pubertal maturation, parental monitoring, involvement in older peer groups, peer dating, and peer delinquency on dating in a sample of early adolescent boys and girls. The sample consisted of 784 adolescents (394 boys, 390 girls) enrolled in grades 5, 6, and 7 who were followed for one year. In addition to measures of pubertal maturation and parental monitoring, adolescents and their peer group members completed indices of dating and delinquency. Average dating and delinquency scores for each participant's peer group network were computed. Results indicated that it was the combination of pubertal maturation, peer delinquency, and peer dating that explained increases in early dating. For boys only, parental monitoring was a significant predictor. The more knowledgeable parents were about their boys' activities, the lower the number of dating activities reported. These results highlight the importance of considering the joint effects of these biological and social predictors in understanding early dating. When rapid changes occur in all three domains, early dating is most likely to ensue. The findings of this study have practical importance. Parents and professionals who work closely with youth should attend to the special vulnerability of early maturing adolescents in the face of peer pressure and to the important role of parental monitoring in regulating dating activities.
OBJECTIVES: Little data exists on dating violence among immigrant adolescents. The present study assessed disparities in experiences of physical and sexual dating violence based on immigrant status and language spoken at home among a large representative sample of adolescent girls. METHODS: Data from the 1997-2003 Massachusetts Youth Risk Behavior Surveys (N = 7,970) were analyzed. Adjusted logistic regression analyses were conducted among the full sample and sexually active sub-sample. To further clarify immigration-based effects, separate analyses were conducted within age and racial/ethnic groups. RESULTS: Being an immigrant was found to be protective against dating violence (OR 0.77, CI 0.60-0.98), but not among those reporting sexual intercourse. Stratified analyses revealed important differences in these effects based on age and race/ethnicity; only immigrant girls age 16 or older (OR 0.69, CI 0.48-0.99) and Hispanic immigrant girls (ORs 0.39-0.54) reported reduced risk for dating violence as compared to their non-immigrants peers. No differences in vulnerability to dating violence were detected based on immigrant status for Asian, Black, or White adolescents in stratified analyses. CONCLUSIONS: The social context of immigration may offer protection regarding adolescent girls' vulnerability to dating violence, but effects are not uniform across age, sexual experience, or race and ethnicity. Additional research is needed to understand how immigration, social behavior, age, race and ethnicity may interact to produce disparities in vulnerability to gender-based violence.
The Safe Dates Project is a randomized trial for evaluating a school-based adolescent dating violence prevention program. Five waves of data were used to examine the effects of Safe Dates over time including primary and secondary prevention effects, moderators, and mediators of program effects. Using random coefficients models, with multiple imputation of missing data, significant program effects were found at all four follow-up periods on psychological, moderate physical, and sexual dating violence perpetration and moderate physical dating violence victimization. Marginal effects were found on sexual victimization. Effects on severe physical perpetration at all four follow-up periods were moderated by prior involvement in that type of violence. Primary and secondary prevention effects were found and the program was equally effective for males and females and for whites and non-whites. Program effects were mediated by changes in dating violence norms, gender-role norms, and awareness of community services.
The present study explored perceived sexual norms and behaviors related to sexual risk and pregnancy involvement among adolescent males (ages 13 to 20) participating in programs for perpetrators of dating violence. The purpose of this study was to generate hypotheses regarding the contexts and mechanisms underlying the intersection of adolescent dating violence, sexual risk and pregnancy. Six focus groups were conducted (N = 34 participants). A number of major themes emerged: 1) male norm of multiple partnering, 2) perceived gain of male social status from claims of sexual activity, 3) perception that rape is uncommon combined with belief that girls claiming to be raped are liars, 4) perception that men rationalize rapes to avoid responsibility, 5) condom non-use in the context of rape and sex involving substance use, 6) beliefs that girls lie and manipulate boys in order to become pregnant and trap them into relationships, and 7) male avoidance of responsibility and negative responses to pregnancy. The combination of peer-supported norms of male multiple partnering and adversarial sexual beliefs appear to support increased male sexual risk, lack of accountability for sexual risk, and rationalization of rape and negative responses to pregnancy. Further research focused on the context of male sexual risk and abusive relationship behaviors is needed to inform intervention with young men to promote sexual health and prevent rape, dating violence, and adolescent pregnancy.
