Pre- and Postintervention Factor Analysis of the Illinois Rape Myth Acceptance Scale

The effects of a bystander education intervention program on the factor structure underlying a rape myth acceptance scale were examined using exploratory factor analyses on secondary data. The Illinois Rape Myth Acceptance Scale was administered to college students at a northwestern university both before (n = 363) and after (n = 352) receiving a bystander education program. Results from exploratory factor analyses showed changes in the factor structure from pretest to posttest. This suggests some instability in the factor structure of the Illinois Rape Myth Acceptance Scale. These pre–post intervention differences in the rape myth acceptance factor structure suggest researchers use caution in using and interpreting scores based on the IRMA without regard to participants’ prevention program status.     

Men who target women: specificity of target, generality of aggressive behavior

Two studies examined the effects of individual differences identified by the Confluence Model of aggression against women [Malamuth Linz, Hevey et al., 1995] and the General Aggression Model [GAM: Anderson and Carnagey, 2004] as predictors of male-on-female aggression. Study 1, a correlational study, found that hostile masculinity predicts self-reported sexual aggression independently of nonsexual aggression against women, and is itself predicted by proneness to general hostility, masculine gender role stress, and violent attitudes toward women. Furthermore, hostility toward women independently predicted sexual and nonsexual aggression against women, above the effects of general attitudes toward violence and general levels of hostility and aggression. Study 2, an experimental study, found that under high provocation, high hostility toward women predicted increases in male nonsexual aggression against women and slight decreases in male aggression against men. This effect remained significant even after controlling for general attitudes toward violence and for general levels of hostility and aggression, indicating that males who are highly hostile toward women specifically target women and that their aggression toward women generalizes beyond sexual aggression. The findings are discussed in terms of a model that integrates the Confluence Model with GAM.     

The attitudes toward forcible date rape (FDR) scale: Development of a measurement model

Using data from 341 female and 237 male college students that were collected previously (Fischer, G. J.,Archives of Sexual Behavior, 15, 457–466, 1986), several true score measurement models were used to describe the variance-covariance structure of a nine-item attitude toward a forcible date rape (FDR) scale. The congeneric true score model fit the data best, but not satisfactorily. By deleting noncongeneric items, a six-item, unweighted linear composite variable based on the congeneric true score model was shown to fit the data, and reliabilities and validities based on this model proved satisfactory for females, males, and the total sample. The factor structure of the model for females and for males was not equivalent, but the general patterns were similar. Suggestions for further research included a validation study of the six-item scale on an independent sample and a comparison of 5-and 7-point Likert response scales to see if the lack of model equivalence by gender could be due, in part, to more variability in attitudes toward forcible date rape in men than women.     

Juror Perceptions in a Rape Trial: Examining the Complainant's Ingestion of Chemical Substances Prior to Sexual Assault

This study examined the impact of a rape complainant's willingness to ingest a chemical substance and the type of ingested substance on the decisions of 229 mock jurors. Jurors were influenced by the type of substance used by the complainant, the complainant's willingness to use a substance, and rape myths. The complainant's ingestion of alcohol (compared to gamma-hydroxybutrate [GHB] and marijuana) led to the highest guilt ratings for the defendant. The complainant who willingly ingested a substance was viewed as less credible and more to blame for the rape compared to one who unwillingly used a substance. The complainant was perceived as the most credible when she unwillingly ingested GHB or marijuana. Jurors high in rape myth acceptance gave lower ratings of guilt to the defendant compared to jurors with lower rape myth acceptance. Overall, the results highlight several juror and case factors that might bias jurors in actual rape trials.     

The goal to be accepted by friends as underlying function of overt aggressive behaviour in immigrant adolescents

This study investigated (1) to what extent the goal to be accepted by friends is an underlying function of overt aggressive behavior in adolescents, and (2) whether this function is more predictive than reactive aggression for overt aggressive behavior in first and second generation immigrants compared with natives. The sample comprised 339 native Austrians (51.6% girls), 126 first generation immigrants (48.4% girls), and 175 second generation immigrants (54.3% girls) aged 14 to 19 (M = 15.61). Data were collected via self-assessments. Multiple group latent means and covariance structures (MACS) models revealed that the goal to be accepted by friends was a stronger predictor than reactive aggression for overt aggressive behavior in first generation immigrants compared with second generation immigrants and natives. Furthermore, gender moderated these associations. The goal to be accepted by friends was a very strong predictor of overt aggressive behavior in first generation immigrant boys, but not in first generation immigrant girls. Results are discussed regarding the process of acculturation in first generation immigrant youth.     

Construct validity and test-retest reliability of a date rape decision-latency measure

In two studies, the construct (convergent and discriminant) validity and test-retest reliability of a date rape decision-latency measure was examined. In Study 1, 174 college men completed measures related to sexual aggression and listened to an audiotaped simulation of a date rape, during which cues of nonconsent and force gradually escalated over time. Participants were instructed to respond, by pressing a button which recorded the latency of their decisions in seconds, if and when they believed the man depicted in the scenario should stop his sexual advances. Results demonstrated positive associations between prolonged decision latencies and sexually aggressive behavior, calloused sexual beliefs, acceptance of interpersonal violence, and sexual promiscuity. In Study 2, initial results were cross-validated in a sample of 102 college men, and discriminant validity was established as decision latencies were unassociated with measures of social desirability, alcohol consumption and drug use. Test-retest reliability assessed over a 2-week interval was .87.The authors wish to thank Alan Gross and Brian Marx for providing the audiotaped stimulus materials, Richard Marsh for writing the decision-latency computer program, Jason Hicks for assisting with programming, and the undergraduate research assistants for serving as experimenters.     

The acceptance of modern myths about sexual aggression scale: development and validation in German and English

Scales of rape myth acceptance (RMA) often yield low means and skewed distributions. This is proposed to be because of a change in rape-related beliefs toward more subtle content. Incorporating insights from racism and sexism research, a 30-item self-report scale measuring the acceptance of modern myths about sexual aggression (AMMSA) is presented. Across four studies (total N=1,279), the reliability and validity of parallel German and English versions of the AMMSA scale were examined. The results show that both language versions are highly reliable; compared with a traditional RMA scale, means of AMMSA scores are higher and their distributions more closely approximate normality. Cross-sectional and longitudinal analyses provide evidence for the AMMSA scale's concurrent and predictive construct validity.     

Assessing aggressive and depressed children's social relations with classmates and friends: a matter of perspective

This study examined aggressive, depressed, and aggressive–depressed childrenr's peer relations from the children's own and from their peers' perspective. Participants were 819 fourth through sixth graders (50.2% girls) who were assessed twice during the same school year. Measures included children's aggression and depression, self-rated and peer-rated social acceptance, number of reciprocal friends, and self-rated and friend-rated friendship quality. Analyses revealed different patterns, depending on the perspective considered. Depression but not aggression was significantly related to difficulties with the peer group and with dyadic friends from the children's own perspective, whereas the opposite pattern was found according to the peers' view. The co-occurrence of aggression and depression entailed significant difficulties with peers regardless of perspective. The implications of these results for the links between children's aggression and depression and their interpersonal relationships are discussed.     

The interplay of modern myths about sexual aggression and moral foundations in the blaming of rape victims

Moral Foundations Theory proposes five intuition-based moral concerns: Care and Fairness (“individualizing foundations”) as well as Loyalty, Authority, and Sanctity (“binding foundations”). In studies carried out in Italy, Spain, and Germany, the authors examined how these concerns are associated with the acceptance of modern myths about sexual aggression (AMMSA), and how both jointly predict rape victim blaming. Overall, victim blaming was positively predicted by Authority and Sanctity, and negatively predicted by Care and Fairness. Although victim blaming was best predicted by AMMSA, moral concerns also contributed to its prediction, partly independently, partly mediated through AMMSA, and in the case of Sanctity in interaction with AMMSA. Discussion highlights how integrating moral foundations in the investigation of victim blaming and AMMSA across different cultural contexts may deepen our understanding of why, in each cultural context, victim blaming and related beliefs are resistant to change.     

Delivered as Described: A Successful Case of Cognitive Processing Therapy With an Older Woman Veteran With PTSD

Cognitive processing therapy (CPT) is a first-line, evidence-based treatment for posttraumatic stress disorder (PTSD). Little is known, however, about the use of CPT for older adults. As the United States population continues to grow and age, an understanding of the utility of CPT for older adults is vital. We present a case study describing the assessment and cognitive treatment of a 74-year-old woman veteran with PTSD secondary to military sexual trauma. CPT was associated with decreased PTSD symptoms as measured before and after treatment. Factors contributing to the veteran’s response, as well as contextual and environmental factors, are discussed. The case demonstrates that CPT may be effective for older adults without major modification.     

Attachment style as a piedictor of sexual attitudes and behavior in late Adolescence

Abstract

This research applied attachment theory to the study of sexual attitudes and behaviors in a sample of late adolescents. Four hundred and seventy heterosexual undergraduate students completed questionnaires assessing attachment (discomfort with closeness; anxiety over relationships). relationship history, communication about sex. sexual self-efficacy and locus of control, and attitudes to condoms. Eight weeks later, participants reported on sexual behaviors occurring during the eight-week interval. and perceived risk of these activities. Both discomfort with closeness and anxiety over relationships were associated with external locus of control for sexual outcomes, and with use of drugs before sexual contact. Anxiety over relationships was linked to unsafe sex and to negative attitudes to condoms, but discomfort with closeness was associated with a more cautious approach to sexual risk-taking. Some results were qualified by gender differences. and by differences between the full sample and those who were sexually active. The findings arc discussed in terms of attachment style and its links with communication and affect regulation.

SUMMARY AND CONCLUSIONS

This study indicates that attachment dimensions are reliably related to many aspects of sexual attitudes and behaviors among late adolescents. Insecure attachment was linked to increased drug use before sexual contact. Anxiety over relationships was also linked to less safe sexual practice, but discomfort with closeness was associated with a tendency for males to be cautious about sexual risk-taking. The results support the utility of the attachment perspective on adolescent sexuality, but also highlight the complex relations between attachment dimensions and sexual outcomes. Future research would benefit from more detailed investigations of the attitudes, emotions, and cognitions which may mediate the link between attachment style and sexual behavior. For example, those who are highly anxious about their relationships may engage in more risky sexual practices because they fear that non-compliance with partners' wishes will jeopardize their relationship; the tendency to engage in drug use before sexual cpntact may reflect their attempts to boost self-confidence or to manage negative mood states. Research into these issues has the potential to explain how attachment insecurity is played out in patterns of sexual activity.     

Mindfulness as a means of reducing aggressive behavior: dispositional and situational evidence

Recent research and theory suggest that mindfulness, or enhanced attention and awareness in the present moment [Brown and Ryan, 2003], may be linked to lower levels of ego-involvement and, as a result, may have implications for lowering hostility and aggressive behavior. Accordingly, we conducted two studies to examine the potential aggression-mitigating role of mindfulness. In Study 1, we found that dispositional mindfulness correlated negatively with self-reported aggressiveness and hostile attribution bias. In Study 2, participants made mindful before receiving social rejection feedback displayed less-aggressive behavior than did rejected participants not made mindful. Discussion centers on potential mechanisms by which mindfulness operates to reduce aggressive behavior.     

Effects of neonatal treatment with cyproterone acetate on aggressive behavior induced by footshock in adult male rats

High levels of androgens are required to organize aggressive behavior in adult male rats. Footshock-induced aggression was tested in Wistar rats allocated to one of three experimental groups: control (oil-injected) males (M), males neonatally injected with the antiandrogen cyproterone acetate (CA), and males treated as in the CA group but gonadectomized just before puberty (CAG). An antiaggressive effect of CA in those adult male rats neonatally treated with this compound was found. Neonatal exposure to cyproterone acetate exerts an antiandrogenic effect over the expression of shock-induced aggressive behavior. The behavioral effects of CA were not countered by adult treatment with testosterone propionate.     

The relationship between aggressive and sexual behavior in male mice: Effects of testosterone and parachlorophenylalanine

The purpose of this study was to clarify the connection between aggressive and sexual behavior with the aid of testosterone propionate (TP) and parachlorophenylalanine (PCPA). Previous studies have indicated that aggressive and sexual behavior are positively correlated, and it has been suggested that both behaviors are related to the level of general arousal. Testosterone has documented effects on both aggressive and sexual behavior. It has been hypothesized that these effects are due to an increased level of general arousal. If this is the case, aggressive and sexual behavior could be restored by administration of drugs excitating the central nervous system, e.g., PCPA. The present study examined the effects of TP and PCPA on aggressive and sexual behavior in gonadectomized male mice. Control animals were injected with sesame seed oil or saline. The level of aggressiveness was assessed by means of dyadic tests with gonad-intact male opponents. For the sexuality tests, a receptive female was placed in the home cage of the experimental male. The results showed that male mice injected with PCPA were more aggressive than the males of the other groups, while the TP-exposed males expressed the most sexual activity. Compared to the control group, the PCPA and TP groups were more active in both the aggression and the sexuality tests. These findings lend support to the hypothesis that the earlier documented correlations between aggressive and sexual behavior could be due to both behaviors being dependent on a certain level of general activation.

Self-Esteem as a Predictor of Attitudes Toward Wife Abuse Among Muslim Women and Men in Canada

Abstract

This study was designed (a) to assess attitudes toward wife abuse in a sample of Muslim women and men in Canada and (b) to assess whether those attitudes were influenced by self-esteem. Results suggested that, as in general North American samples, the Muslim women and men did not differ from each other on levels of self-esteem. Also consistent with general North American samples, the Muslim women's and men's attitudes toward wife abuse were related to their self-esteem, with higher self-esteem scores predicting stronger attitudes against wife abuse, independent of gender. However, the results also revealed that the Muslim men had significantly more lenient attitudes toward wife abuse compared with the Muslim women and with North American norms.     

Risk factors for sexual aggression in young men: an expansion of the confluence model

There are many explanations for high rates of sexual aggression, with no one theory dominating the field. This study extends past research by evaluating an expanded version of the confluence model with a community sample. One-hour audio computer-assisted self-interviews were completed by 470 young single men. Using structural equation analyses, delinquency, hostile masculinity, impersonal sex, and misperception of women's sexual cues were positively and directly associated with the number of sexually aggressive acts committed. There were also indirect effects of childhood victimization, personality traits associated with subclinical levels of psychopathy, and alcohol consumption. These findings demonstrate the usefulness of the confluence model, as well as the importance of broadening this theory to include additional constructs.     

Comprehension of Sexual Consent as a Key Factor in the Perpetration of Sexual Aggression Among College Men

The comprehension of sexual consent is a crucial factor in healthy sexual relationships. This study examined the connection between the understanding of sexual consent and perpetration of sexual aggression. We surveyed 217 heterosexual male college students (M age = 20.9 years) using measures of sexual aggression, comprehension of sexual consent, rape myth acceptance, conformity to masculine norms, peer support of abuse, and attachment to abusive peers. We tested models examining factors related to comprehension of consent and the extent to which comprehension of consent was related to perpetration of sexual aggression. Rape myth acceptance, peer support of abuse, and conformity to masculine norms were found to predict comprehension of consent, which mediated the relationship between the social and cognitive variables and sexual aggression.     

Public house patrons' engagement in hypothetical sexual assault: a test of Alcohol Myopia Theory in a field setting

Previous research has found that drinking establishments are often antecedent to sexual aggression outcomes. In this study, male participants were randomly selected from public houses (i.e., "pubs") and asked to imagine themselves in a hypothetical intimate encounter in which the female in the scenario stops consenting to sexual contact. Participants were given the option to continue making sexual advances up to and including sexual intercourse against the woman's will. It was hypothesized based on Alcohol Myopia Theory that participant blood alcohol concentration (BAC) levels would be associated with hypothetical sexual aggression when stereotypical cues of a woman's sexual availability (revealing clothing and alcohol use) were present in the scenario. Men's engagement in hypothetical sexual aggression was associated with BAC levels, but only when the woman was wearing revealing clothing. The sobriety of the female actor was not associated with sexual aggression. Results indicate that Alcohol Myopia Theory generalizes to a field setting.
