ABSTRACT

OBJECTIVE: Sexually aggressive behavior (SAB), risky sexual behavior (RSB), and heavy episodic drinking (HED) are serious behavioral health problems among college men. The present study substantially revises and validates protective behavioral strategies (PBS) measures in the SAB and RSB domains; evaluates the relations among PBS usage in the SAB, RSB, and HED domains; and determines whether college men with SAB, RSB, or HED histories report lower PBS usage. METHOD: College students who identified as men (n = 1,121) completed measures of PBS, SAB, RSB, HED, rape-supportive attitudes, sociosexuality, and bar/party attendance. RESULTS: Factor analyses resulted in three PBS scales (SAB, RSB-General, and RSB-Protection) that showed good fit and cross-validated well. Average scores for all four PBS measures converged moderately to strongly. Men reporting histories of SAB, RSB, or HED reported much lower domain-specific PBS use, and domain-specific PBS predicted concurrent SAB, RSB, or HED in the presence of other established predictors. CONCLUSIONS: Four well-developed and validated PBS measures now provide an expanded set of potential harm-reduction strategies for college men who drink and engage in sexual activity. Given the strong concurrent associations between PBS use and problems, as well as the interrelatedness of PBS use across domains, future research should examine the impact of simultaneous personalized normative feedback on PBS use across alcohol and sexual domains.

ABSTRACT

Bondage/discipline, dominance/submission, and sadism/masochism (BDSM) proclivity among college students is poorly characterized, in part because existing measures of BDSM proclivity highlight the consensual nature of BDSM and are appropriate for use with non-community members (e.g., those who may not understand BDSM jargon). The current study introduces such a measure, the BDSM Proclivity Scale, which characterizes BDSM proclivity among college students and evaluates relations of BDSM proclivity with other sexual attitudes and behaviors. College students (n = 552) completed measures of BDSM proclivity, sociosexual attitudes and behaviors, rape-supportive attitudes, lifetime sexual partners, and consent-seeking behavior. Two factors mapping onto attitudes and experiences related to BDSM were identified and cross-validated. Average endorsements of BDSM attitudes and experiences on a 7-point Likert scale (1 = strong disagreement, 7 = strong agreement) were 5.61 and 4.44, respectively. Structural models revealed that lifetime sexual contact and gender significantly positively correlated with BDSM attitudes and experiences, sociosexual attitudes positively correlated with BDSM attitudes, and rape-supportive attitudes positively correlated with BDSM experiences. Consent-seeking was unrelated to BDSM experiences or attitudes. College student BDSM proclivity was evident for both attitudes and experiences, highlighting the need to characterize the development of BDSM proclivity and its correlates, the sources of students' knowledge, and the nature of students' experiences. The observed associations between BDSM proclivity and relevant sexual attitudes and behaviors support its construct validity and suggest that BDSM proclivity may prove to be an important addition to the broader constructs assessed in sexual attitudinal and behavioral domains.

ABSTRACT

Acquaintance-initiated sexually aggressive behavior (SAB) is a widespread problem on college campuses, and intervention strategies thus far have not produced sustained reductions in SAB. Peer-related social norms and cognitive processes underlying sexual decision-making have separately been implicated in SAB. The present study integrates this work by examining the effect of perspective (self vs. typical college male referent) on college men's judgments of the justifiability of unwanted sexual advances, determining the cognitive processes underlying men's misperceptions, and evaluating rape-supportive attitudes (RSA) as a correlate of the implicated processes. College men attracted to women (n = 217) completed the Heterosocial Perception Survey-Revised, in which they judged the justifiability of a man's increasingly intimate sexual advances as a woman responds increasingly negatively. Participants completed the Heterosocial Perception Survey-Revised from their own perspective and from the typical college male perspective. Participants also completed questionnaires assessing RSA and demographics. Undergraduate men, and particularly those endorsing more RSA, greatly overestimated how much the typical college male perceives increasingly nonconsensual behavior as justified. Three cognitive processes were strongly implicated in this misperception. When responding from the self-perspective, RSA correlated significantly with all cognitive processes. These findings illustrate the utility of integrating work on social norms and cognitive processing to document the global effect of perspective on average justifiability ratings and the perspective effect on cognitive processes underlying the ratings. Future work should evaluate personalized normative feedback and cognitive-training approaches to target misperceptions of peers' sexual judgments, given the well-established relation between sexual misperception and SAB risk.

ABSTRACT

Major depression is associated with alterations in the auditory P3 event-related potential (ERP). However, the persistence of these abnormalities after recovery from depressive episodes, especially in young adults, is not well known. Furthermore, the potential influence of substance use on this association is poorly understood. Young adult twin pairs (N = 177) from the longitudinal FinnTwin16 study were studied with a psychiatric interview, and P3a and P3b ERPs elicited by task-irrelevant novel sounds and targets, respectively. Dyadic linear mixed-effect models were used to distinguish the effects of lifetime major depressive disorder from familial factors and effects of alcohol problem drinking and tobacco smoking. P3a amplitude was significantly increased and P3b latency decreased, in individuals with a history of lifetime major depression, when controlling the fixed effects of alcohol abuse, tobacco, gender, twins' birth order, and zygosity. These results suggest that past lifetime major depressive disorder may be associated with enhanced attentional sensitivity.

ABSTRACT

Sexual aggression (SA) is a serious public-health problem on college campuses, and there is a pressing need for basic research fostering the development of novel prevention strategies. The current study (a) developed measures of protective behavioral strategies (PBS) for sexual aggression (SA) and risky sex (RS); (b) characterized college men's PBS use; and (c) evaluated whether those who reported engaging in SA and RS showed lower PBS use. Undergraduate men from two universities (n = 567) who endorsed sexual attraction toward women completed measures of PBS, SA, RS, rape-supportive and sociosexual attitudes, and alcohol consumption. On average, participants reported using PBS for SA and RS fairly often, but a sizeable number indicated that they seldom or never used the strategies. Men who reported SA engagement in the last year, relative to their peers, endorsed sharply lower reliance on SA PBS and RS PBS. Men who reported at least one RS behavior in the last year used RS PBS far less often than their peers. The PBS measures converged as expected with other attitudinal and behavioral measures. The new PBS measures reference cognitive-behavioral approaches that a large percentage of college men use on a regular basis, making them potentially acceptable prevention targets. Further, men at greater risk of exhibiting SA are much less likely to take steps to reduce the risks associated with sexual behavior, in comparison with their peers. Thus, future work could evaluate the potential usefulness of incorporating PBS for SA and RS into primary prevention programming in both domains.

ABSTRACT

Despite widespread use in schizophrenia-spectrum research, uncertainty remains around an empirically supported and theoretically meaningful factor structure of the Schizotypal Personality Questionnaire (SPQ). Current identified structures are limited by reliance on exclusively nonclinical samples. The current study compared factor structures of the SPQ in a sample of 335 nonpsychiatric individuals, 292 schizotypy-spectrum individuals (schizophrenia, schizoaffective disorder, or schizotypal personality disorder), and the combined group (N = 627). Unidimensional, correlated, and hierarchical models were assessed in addition to a bifactor model, wherein subscales load simultaneously onto a general factor and a specific factor. The best-fitting model across samples was a two-specific factor bifactor model, consistent with the nine symptom dimensions of schizotypy as primarily a direct manifestation of a unitary construct. Such findings, for the first time demonstrated in a clinical sample, have broad implications for transdiagnostic approaches, including reifying schizotypy as a construct underlying diverse manifestations of phenomenology across a wide range of severity.

ABSTRACT

This study analyzes data from seven published studies to examine whether three performance-based indices of men's misperception of women's sexual interest (MSI), derived from a self-report questionnaire, are associated with sexual-aggression history, rape-supportive attitudes, sociosexuality, problem drinking, and self-reported MSI. Almost 2000 undergraduate men judged the justifiability of a man's increasingly unwanted advances toward a woman on the Heterosocial Perception Survey-Revised. Participants self-reported any sexual-aggression history, and some completed questionnaires assessing rape-supportive attitudes, sociosexuality, problem drinking, and self-reported MSI. A three-parameter logistic function was fitted to participants' justifiability ratings within a non-linear mixed-effects framework, which provided precise participant-specific estimates of three sexual-perception processes (baseline justifiability, bias, and sensitivity). Sexual-aggression history and rape-supportive attitudes predicted: (a) reduced sensitivity to women's affect; (b) more liberal biases, such that the woman's affect had to be more negative before justifiability ratings dropped substantially; and (c) greater baseline justifiability of continued advances after a positive response. Sexual-aggression history and attitudes correlated more strongly with sensitivity than baseline justifiability; remaining variables showed the opposite pattern. This work underscores the role of sexual-perception processes in sexual aggression and illustrates the derivation of performance-based estimates of sexual-perception processes from questionnaire responses.

ABSTRACT

This study evaluated the effects of alcohol intoxication, sexual attitudes, and sexual victimization history on the cognitive processes underlying undergraduate women's risk judgments. Participants were 116 unmarried, undergraduate women between the ages of 21 and 29. The sample was diverse ethnically and composed primarily of heterosexual women. Stimuli were written vignettes describing social situations that varied on dimensions of sexual victimization risk and potential impact on women's popularity. Participants were assigned randomly to an alcohol or a no-alcohol condition, and completed an explicit classification task in which they rated how risky each situation was in terms of their having an unwanted sexual experience. They then completed the Sexual Experiences Survey (SES) and the Sociosexuality Scale (SS); SES responses were used to quantify the severity of victimization experiences, and SS responses were used to measure endorsement of positive attitudes toward casual, impersonal sex. Although there was no main effect for condition, higher sociosexuality predicted use of higher thresholds for judging situations as risky. Importantly, sociosexuality interacted with condition such that higher sociosexuality predicted lower sensitivity to risk information in the alcohol condition but not in the no-alcohol condition. More severe victimization history predicted increased use of popularity impactwhen judging risk. This study emphasizes the importance of identifying specific cognitive processes affected by alcohol that may explain why women have difficulty processing contextual cues signaling risk in social situations. It demonstrates also the relevance of examining individual difference factors that may exacerbate the relationship between intoxication and cognitive processing of risk-relevant information.

ABSTRACT

Contemporary models of male-initiated sexual aggression toward female acquaintances implicate misperception of women's sexual interest. This study investigated the effects of gender, rape-supportive attitudes and an instructional manipulation on college students' sexual-interest judgments. Two hundred seventy-six women and 220 men judged the cues of momentary sexual interest expressed by photographed women; half received instruction on the differential validity of nonverbal cues of sexual interest for estimation of women's momentary sexual interest. Participants also completed an assessment of rape-supportive attitudes. Overall, college students' perceptions of women's momentary sexual interest are compromised both nomothetically and idiographically. Both male and female college students relied not only on women's nonverbal affect but also on the provocativeness of women's clothing and attractiveness when judging women's sexual interest. Men and women showed similar average ratings, but women relied more than men on women's affect, whereas men relied more than women on women's attractiveness. Both male and female students who endorsed more rape-supportive attitudes, relative to their peers, relied less on women's affect and more on women's clothing style and attractiveness. Explicit instruction regarding the greater validity of women's affective than nonaffective cues enhanced focus on nonverbal affective cues and decreased focus on clothing style and attractiveness. Although higher rape-supportive attitudes predicted more deficits in processing cues of sexual interest, explicit instruction proved to be effective for both higher-risk and lower-risk participants. These findings highlight the generalizability of the well-established effects of explicit instruction on category learning to sexual perception and may point to procedures that eventually could be incorporated into augmented prevention programs for sexual aggression on college campuses.

ABSTRACT

Men's perceptions of women's sexual interest were studied in a sample of 250 male undergraduates, who rated 173 full-body photos of women differing in expressed cues of sexual interest, attractiveness, provocativeness of dress, and the social-environmental context into which the woman's photo had been embedded. Environmental context significantly influenced men's judgments of sexual interest, independently of the affective cues of sexual interest themselves and of provocativeness of dress and attractiveness. Cue usage was moderated by men's risk for sexual aggression, as measured by a rape-myth inventory, with higher-risk men (relative to lower-risk men) relying significantly less on affective cues, relying significantly more on attractiveness, and showing a non-significant tendency to rely more on environmental cues. Men exhibited a moderate degree of insight into individual differences in their cue usage. Analysis of individual differences in cue usage suggested that men's judgments of women's momentary sexual interest varied along two dimensions: (1) men who relied more on affective cues were less likely to rely on women's attractiveness (r = -0.73); and (2) men who were influenced more by provocativeness of dress were also likely to rely more on environmental context (r = 0.49). Results suggest that variation in contextual variables should be included in cognitive-training programs designed to improve the accuracy of men's judgments of women's affective responses. Ultimately, such training programs may prove useful as an adjunct to prevention programs for sexual aggression.

ABSTRACT

The current study evaluated whether the sexual relevance of the social environment potentiated men's judgments of women's sexual interest, particularly among men reporting more frequent misperception of a potential partner's sexual interest. Twenty-eight scenes were constructed depicting social environments that were either lower or higher in sexual relevance (e.g., office vs. bar). A full-body photograph of one of 14 college-aged women was inserted into each scene; the women all expressed neutral-to-positive affect and varied in provocativeness of dress and attractiveness. A total of 237 undergraduate males viewed each scene and judged how sexually interested and friendly each woman felt. Sexually relevant social environments potentiated men's judgments of women's sexual interest far more than their friendliness. This effect was stronger among more conservatively dressed women and among men reporting more frequent experiences of misperceiving a woman's sexual interest. The findings highlight the contextualized nature of emotional perception, whereby perception of emotion is potentiated in congruent, relative to incongruent, contexts.

ABSTRACT

BACKGROUND: Alcohol consumption is influenced by heritable factors. The genetic influence on usual high-density drinking, including alcohol intoxication and hangover, is unknown. We aim to estimate the heritability of usual high-density drinking. METHODS: A total of 13,511 male twins in this cross-sectional study were included from the National Academy of Sciences-National Research Council (NAS-NRC) Twin Registry. Data on the frequency of alcohol intoxication and alcohol hangover over the past year, that is, usual high-density drinking (phenotypes), were collected through a self-administered questionnaire when twins were middle-aged in 1972. Structural equation modeling was used to estimate the variance components of phenotypes. RESULTS: The mean of the frequency of usual high-density drinking in the entire twin population was 0.16 times per month for intoxication and 0.18 times per month for hangover. The heritability of usual alcohol intoxication was 50.7% (95% confidence interval [CI] 46.2 to 55.0) before and 49.9% (95% CI 45.3 to 54.2) after the body mass index (BMI) adjustment. The heritability of usual hangover was 55.4% (95% CI 51.2 to 58.6) before and 54.8% (95% CI 50.6 to 58.8) after adjustment for BMI. Unshared environmental factors between co-twins explained the remaining variance in alcohol intoxication and in hangover. CONCLUSIONS: Both genetic and unshared environmental factors have important influences on usual alcohol intoxication and hangover. These findings are important in understanding the occurrence of and developing interventions for usual high-density drinking.

ABSTRACT

BACKGROUND: Adolescent alcohol abuse is associated with adverse outcomes in early adulthood, but differences in familial status and structure and household and community environments correlate with both adolescent drinking and adverse adult outcomes and may explain their association. We studied drinking-discordant twin pairs to evaluate such confounds to ask: Will between-family associations replicate in within-family comparisons? METHODS: With longitudinal data from >3,000 Finnish twins, we associated drinking problems at age 18½ with 13 outcomes assessed at age 25; included were sustained substance abuse, poor health, physical symptoms, early coital debut, multiple sexual partners, life dissatisfaction, truncated education, and financial problems. We assessed associations among twins as individuals with linear regression adjusted for correlated observations; within-family analyses of discordant twin pairs followed, comparing paired means for adult outcomes among co-twins discordant for adolescent problem drinking. Defining discordance by extreme scores on self-reported problem drinking at age 18½ permitted parallel analyses of twins as individuals and discordant twin pairs. Alternate definitions of pair-wise discordance and difference score correlations across the entire twin sample yielded supplementary analyses. RESULTS: All individual associations were highly significant for all definitions of discordance we employed. Depending on definitions of discordance, 11 to 13 comparisons of all drinking-discordant twin pairs and 3 to 6 comparisons of discordant monozygotic (MZ) twin pairs replicated between-family associations. For most outcomes, effect size attenuated from individual-level analysis to that within discordant MZ twin pairs providing evidence of partial confounding in associations reported in earlier research. The exception was the General Health Questionnaire (GHQ); at age 25, GHQ-12 had equivalent associations with age 18½ Rutgers Alcohol Problem Index across all comparisons. CONCLUSIONS: Our analyses control for shared family background, and, partly or fully, for shared genes, to yield within-family replications and more compelling evidence than previously available that adolescent alcohol abuse disrupts transitions into early adulthood.

ABSTRACT

OBJECTIVE: To determine whether family members and friends can be accurate reporters of depression in older women and whether their reports predict diagnostic depression concurrently and across a one-year time interval. METHOD: African-American and Caucasian older women (N = 153; mean age = 75) previously screened for depression nominated network members (NMs) who could be contacted as informants. NMs completed an informant version of the CES-D, described their closeness to the participant, the extent of the participant's support from family and friends, and their assessment of the participant's typical coping strategies. These reports were then used to predict participant CES-D, Hamilton depression scores, and Structured Clinical Interview (SCID) depression diagnoses concurrently and at six-month and one-year intervals. RESULTS: NMs' estimates of participants CES-D status were highly correlated with participants own CES-D scores, and also predicted Hamilton depression scores and SCID diagnoses concurrently and at six months and one year later. NMs' ratings of participants' use of positive coping also predicted depression at six months and one year. CONCLUSION: NMs knew when elderly women were depressed and their reports were accurate predictors of depression even one year later, which implies that elderly depression does not abate spontaneously. Future research should test the possibility that family and friends might be recruited as allies in encouraging earlier treatment and in providing support to older adults through difficult life transitions.

ABSTRACT

BACKGROUND: Long-term functional brain effects of adolescent alcohol abuse remain uncertain, partially because of difficulties in distinguishing inherited deficits from neuronal effects of ethanol and by confounds associated with alcohol abuse, especially nicotine exposure. We conducted a longitudinal twin study to determine neurocognitive effects of adolescent alcohol abuse, as measured with the auditory event-related potential (ERP) component P3, a putative marker of genetic vulnerability to alcoholism. METHODS: Twin pairs (N=177; 150 selected for intrapair concordance/discordance for alcohol-related problems at age 18½) were recruited from ongoing studies of twins born 1975-1979 in Finland. Alcohol and tobacco use were assessed with questionnaires at ages 16, 17, 18½, and ~25, and by a structured psychiatric interview concurrent with the ERP testing at mean age 25.8. During ERP recordings, subjects were instructed to detect target tones within a train of frequent "standards" and to ignore occasional "novel" sounds. To distinguish familial factors from ethanol effects, ERP and self-reported alcohol use measures were incorporated into hierarchical multiple regression (HMR) analysis, and intrapair differences in ERP were associated with intra-pair differences in alcohol variables. RESULTS: Novel-sound P3 amplitude correlated negatively with self-reported alcohol use in both between- and within-family analyses. No similar effect was observed for target-tone P3. HMR results suggest that twins' similarity for novel-sound P3 amplitude is modulated by their alcohol use, and this effect of alcohol use is influenced by genetic factors. CONCLUSIONS: Our results, from a large sample of twins selected from a population-based registry for pairwise concordance/discordance for alcohol problems at 18½, demonstrate that adolescent alcohol abuse is associated with subtle neurophysiological changes in attention and orienting. The changes are reflected in decreased novel-sound P3 amplitude and may be modified by genetic factors.

ABSTRACT

OBJECTIVE: A lower level of education often co-occurs with alcohol problems, but factors underlying this co-occurrence are not well understood. Specifically, whether these outcomes share part of their underlying genetic influences has not been widely studied. Educational level also reflects various environmental influences that may moderate the genetic etiology of alcohol problems, but gene-environment interactions between educational attainment and alcohol problems are unknown. METHOD: We studied the two non-mutually exclusive possibilities of common genetic influences and gene-environment interaction between alcohol problems and low education using a population-based sample (n = 4,858) of Finnish young adult twins (M(age) = 24.5 years, range: 22.8-28.6 years). Alcohol problems were assessed with the Rutgers Alcohol Problem Index and self-reported maximum number of drinks consumed in a 24-hour period. Years of education, based on completed and ongoing studies, represented educational level. RESULTS: Educational level was inversely associated with alcohol problems in young adulthood, and this association was most parsimoniously explained by overlapping genetic influences. Independent of this co-occurrence, higher education was associated with increased relative importance of genetic influences on alcohol problems, whereas environmental factors had a greater effect among twins with lower education. CONCLUSIONS: Our findings suggest a complex relationship between educational level and alcohol problems in young adulthood. Lower education is related to higher levels of alcohol problems, and this co-occurrence is influenced by genetic factors affecting both phenotypes. In addition, educational level moderates the importance of genetic and environmental influences on alcohol problems, possibly reflecting differences in social-control mechanisms related to educational level.

ABSTRACT

This study evaluated the effects of a sexual victimization history and the contextual features of sexual activity and alcohol use on the effectiveness of women's responses to 44 written vignettes describing diverse dating and social situations. One hundred and one undergraduate women reported their history of sexual victimization and provided written descriptions of how they would respond to each vignette. Experts in the sexual violence research area then evaluated the effectiveness of these responses in decreasing risk of having an unwanted sexual experience, meaning one in which the woman is verbally or physically coerced into having sexual contact of any kind with a man. Results revealed that past victimization moderated the influence of the situations' contextual features on women's response effectiveness. Specifically, as the presence of sexual activity increased in the situations, the response effectiveness of more severely victimized women increased less than nonvictimized women. In addition, as the presence of alcohol increased in the situations the response effectiveness of more severely victimized women decreased more than that of nonvictimized women.

ABSTRACT

Probably the most robust sex difference in cognitive abilities is that on average males outperform females in tests of mental rotation. Using twin data we tested whether there are sex differences in the magnitude of genetic and environmental effects on mental rotation test performance and whether the same or different genetic effects operate in females and males. The present study replicated the well-known male advantage in mental rotation ability. The relative proportion of variance explained by genetic effects did not differ between females and males, but interestingly, absolute additive genetic and unique environmental variances were greater in males reflecting significantly greater phenotypic variance in mental rotation test performance in males. Over half of the variance in mental rotation test performance was explained by genetic effects, which suggest that mental rotation ability is a good phenotype for studies finding genes underlying spatial abilities. Results indicate that females and males could be combined for such genetic studies, because the same genetic effects affected mental rotation test performance in females and males.

ABSTRACT

Young men's errors in sexual perception have been linked to sexual coercion. The current investigation sought to explicate the perceptual and decisional sources of these social perception errors, as well as their link to risk for sexual violence. General Recognition Theory (GRT; [Ashby, F. G., & Townsend, J. T. (1986). Varieties of perceptual independence. Psychological Review, 93, 154-179]) was used to estimate participants' ability to discriminate between affective cues and clothing style cues and to measure illusory correlations between men's perception of women's clothing style and sexual interest. High-risk men were less sensitive to the distinction between women's friendly and sexual interest cues relative to other men. In addition, they were more likely to perceive an illusory correlation between women's diagnostic sexual interest cues (e.g., facial affect) and non-diagnostic cues (e.g., provocative clothing), which increases the probability that high-risk men will misperceive friendly women as intending to communicate sexual interest. The results provide information about the degree of risk conferred by individual differences in perceptual processing of women's interest cues, and also illustrate how translational scientists might adapt GRT to examine research questions about individual differences in social perception.
