Alcohol Use, Rape Myth Acceptance, Rape Empathy, and Sexual Assault History Influence the Believability of a Hypothetical Victim's Report of Sexual Assault.

College sexual assault is a common problem, and survivors often do not report their experience to college campus officials or law enforcement for fear of not being believed. This study examined how contextual factors such as alcohol use and whether the perpetrator was described as a student-athlete or student, and rater characteristics, such as the history of sexual assault and attitudes toward rape, influenced college students' perceptions of the believability of a hypothetical victim's sexual assault account. In all, 449 (N = 449) undergraduates read a vignette describing a hypothetical sexual assault and were assigned randomly to one of four conditions with varying contextual features: college athlete-no alcohol, college athlete-alcohol, college student-no alcohol, or college student-alcohol. They then rated how much they believed the victim in the vignette had been raped (0 [not at all] to 100 [completely]). The presence of alcohol use in the vignette was associated with lower ratings of believability, and participants who were higher in rape myth acceptance and lower in rape empathy rated the hypothetical victim's rape account as less believable. In addition, women who had been raped previously rated the victim in the vignette as more believable than women with no history of sexual assault. Implications for how college campuses might respond more effectively to reported sexual assaults are discussed.

Risk for dating violence and sexual assault over time: The role of college and prior experiences with violence.

Objective: Despite increased research on emerging adults and interpersonal violence, evidence on the role of college attendance in risk for dating violence and sexual assault is mixed. We examined the role of college attendance on victimization risk in emerging adulthood. Participants: Participants were a diverse longitudinal sample of 630 emerging adults. Methods: We conducted regression analyses to examine the association of college attendance by type (community and public/private four year) with subsequent victimization, controlling for prior victimization and other factors. Results: Participants who attended public and private four-year colleges had significantly less risk for physical dating violence (OR = 0.35, p < 0.001), but not prior sexual or psychological dating violence or other sexual assault. Prior victimization was the most significant predictor of victimization in emerging adulthood. Conclusions: The context of higher education and prior victimization experience should be considered for addressing dating violence and sexual assault in emerging adulthood.

Instructor facilitation mediates students' negative perceptions of active learning instruction.

Studies have demonstrated students' resistance to active learning, despite evidence illustrating that their learning is improved relative to students in lectures. Specifically, while active learning and group work are effective at engaging students in their learning process, studies report that students' perceptions of active learning approaches are not always positive. What remains underexplored is whether students' perceptions of active learning improve with effective instructor facilitation and whether there exists differential perceptions between racially minoritized students and represented students. Here, we estimate students' perceptions of effective instructor facilitation as the mediator in the relationship between active learning and perceptions of learning and perceived utility for class activities (task value). Then, we examine differences by racial identification. We collected classroom observation data to empirically categorize courses as active learning or lecture-based and surveyed 4,257 college students across 25 STEM classrooms at a research-intensive university. We first examined the relationship between active learning on student perceptions and found a negative relationship between active learning and perceptions of learning and task value for both racially minoritized students and represented students. Next, we assessed whether students' perceptions of instructor effectiveness in facilitating group activities mediate these negative relationships. We found that, on average, students of all races were more likely to positively perceive instructor facilitation in active learning classes relative to lectures. In turn, the positive perceptions of instructor facilitation partially suppressed the negative relationship between active learning and perceptions of learning and task value. These results demonstrate that effective instructor facilitation can influence both students' self-assessment of learning and perceived utility of the learning activities, and underscores the importance of developing pedagogical competence among college instructors.

Risky Sexual Behavior among Arrested Adolescent Males: The Role of Future Expectations and Impulse Control.

The current study evaluates two predictors of adolescent sexual risk-taking, specifically whether impulse control or future expectations predict condom use and casual sex. We examine whether risky sex occurs among youth who tend to act without thinking about the future, or instead, youth who report low future expectations. We consider these relations longitudinally among a sample of sexually active justice-involved adolescent males (N = 752, M age = 15.58) a group at heightened risk for sexual risk-taking. We found that optimistic expectations for the future predict a higher likelihood of engaging in consistent condom use, whereas high impulse control is related to a lower likelihood of casual sex. Implications for intervention and research on positive sexual health are discussed.

Do Some Students Need Special Protection From Research on Sex and Trauma? New Evidence for Young Adult Resilience in "Sensitive Topics" Research.

Institutional review boards (IRBs) have expressed concerns that certain individuals or groups, such as participants who are younger, ethnic minorities, or who have certain psychological or personality traits, may be particularly distressed when participating in "sensitive topics" research. This study examined the effects of several demographic and individual difference factors (i.e., age, sex, ethnicity, religiosity, Big Five personality traits, and baseline psychological distress levels) on reactions to participation in sensitive topics research. Participants were 504 undergraduates who completed an extensive battery of either trauma/sex questionnaires or cognitive tests and rated their positive and negative emotional reactions and the perceived benefits and mental costs of participating. They also compared research participation to normal life stressors. Our findings indicated that individual difference and demographic risk factors do not increase participant distress after participating in sex/trauma research over and above that experienced after participating in traditionally minimal-risk cognitive tasks. Participants generally found research participation less distressing than normal life stressors and even enjoyable.

Can the Theory of Planned Behavior predict dietary intention and future dieting in an ethnically diverse sample of overweight and obese veterans attending medical clinics?

Obesity has become a world-wide epidemic; in the United States (U.S.) approximately two-thirds of adults are classified as overweight or obese. Military veterans' numbers are even higher, with 77% of retired or discharged U.S. veterans falling in these weight categories. One of the most common methods of changing one's weight is through dieting, yet little is known regarding the factors that facilitate successful dieting behavior. The current investigation tested the Theory of Planned Behavior's (TPB) ability to predict dietary intention and future dieting in a sample of 84 overweight and obese patients attending medical clinics at a Veterans Affairs Hospital in the southwestern part of the U.S. Participants primarily were male (92%) and ethnic/racial minorities (58%). Perceived need and anticipated regret were added to the standard TPB model. While the TPB predicted dietary intention, it did not significantly account for improved dietary behaviors. Anticipated regret significantly enhanced the basic TPB's ability to predict intention to diet, while perceived need did not. These findings highlight the difficulty in predicting sustained change in a complex behavior such as dieting to lose weight. The need for more work with older, overweight/obese medical patients attending veterans' facilities is stressed, as is the need for such work with male patients and ethnic minorities in particular.

Neighborhood Factors and Dating Violence Among Youth: A Systematic Review.

CONTEXT: The purpose of this review is to summarize the empirical research on neighborhood-level factors and dating violence among adolescents and emerging adults to guide future research and practice. EVIDENCE ACQUISITION: In 2015, a total of 20 articles were identified through a search of the literature using PubMed. Eligible articles included those that (1) had been published in a peer-reviewed journal since 2005; (2) reported a measure of association between at least one neighborhood-level factor and dating violence; and (3) had a study population of youth aged <26 years. We abstracted information about the studies, including measurement of dating violence and neighborhood factors, and measures of effect. EVIDENCE SYNTHESIS: Results were summarized into three categories based on the aspect of neighborhood that was the focus of the work: demographic and structural characteristics (n=11); neighborhood disorder (n=12); and social disorganization (n=8). There was some evidence to suggest that neighborhood disadvantage is associated with dating violence, but very little evidence to suggest that residence characteristics (e.g., racial heterogeneity) are associated with dating violence. Results do suggest that perceived neighborhood disorder is associated with physical dating violence perpetration, but do not suggest that it is associated with physical dating violence victimization. Social control and community connectedness are both associated with dating violence, but findings on collective efficacy are mixed. CONCLUSIONS: Existing research suggests that neighborhood factors may be associated with dating violence. However, there is a limited body of research on the neighborhood context of dating violence, and more rigorous research is needed.

Using cognitive theory and methodology to inform the study of sexual victimization.

Sexual victimization is a prevalent problem among college-aged women. In order to investigate the mechanisms underlying sexual victimization, researchers have focused on the role of cognitive processes such as perception of sexual victimization risk, positing that difficulties with risk perception heighten women's risk for victimization. However, researchers generally have not conceptualized risk perception in the context of a comprehensive cognitive model or utilized tasks and stimuli that allow them to examine specific cognitive processes linked to increased risk for sexual victimization. This review examines the research on sexual victimization risk perception, citing benefits and limitations to the extant literature, and discusses how a promising hybrid approach using cognitive theory and methodology can be applied to this area to better understand women's risk for sexual victimization.

The role of ethnicity, sexual attitudes, and sexual behavior in sexual revictimization during the transition to emerging adulthood.

An experience of child sexual abuse (CSA) substantially increases women's risk of adult sexual assault (ASA), but the mechanisms underlying this relationship are unclear. Previous research often has not examined the full range of ASA experiences or included the influence of ethnicity, sexual behavior, and sexual attitudes on CSA and severity of ASA. The current study utilized path analysis to explore the relationships among ethnicity, sexual attitudes, number of lifetime sexual partners, CSA, and severity of ASA in emerging adult women. Results indicated a significant relationship between CSA and more severe ASA that was partially explained by having more lifetime sexual partners. Additionally, European American women, relative to Hispanic women, reported more severe victimization, which was fully explained by more positive attitudes toward casual sex and having more lifetime sexual partners. These results have implications in the design and implementation of universal and selective prevention programs aimed at reducing ASA and revictimization among emerging adult women.

Relationship between arm usage and instrumental activities of daily living after unilateral stroke.

OBJECTIVE: To determine whether the preferred pattern of arm use after unilateral hemispheric damage was associated with better everyday functioning. Our previous work showed that right-handed stroke patients with right hemisphere damage (RHD) used their right, ipsilesional arm most frequently, while those with left hemisphere damage (LHD) used both arms together most frequently. This effect was explained by right-hand preference, but its relationship to functional performance is not known. DESIGN: Observational cohort. SETTING: Research laboratory. PARTICIPANTS: Stroke patients (n=60; 30 RHD, 30 LHD) and healthy controls (n=52). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The Functional Impact Assessment was used to assess performance on instrumental activities of daily living (IADLs). RESULTS: The preferred patterns of arm use were similar to those in our previous report. However, it was the greater use of both arms together that was associated with better IADL performance in both stroke groups. Ipsilesional arm use alone was not significantly associated with IADL performance in the RHD group and was associated with poorer performance in the LHD group. CONCLUSIONS: The modal arm use pattern did not always optimize IADL functioning. Better IADL functioning in both stroke groups was associated with the use of both arms together, which is the most common arm use pattern of healthy individuals doing these same IADLs. An important practical question that arises from these findings is whether bilateral arm rehabilitation should be emphasized, because using both arms together is the best predictor of better performance on everyday tasks.

Trauma and sex surveys meet minimal risk standards: implications for institutional review boards.

Institutional review boards assume that questionnaires asking about "sensitive" topics (e.g., trauma and sex) pose more risk to respondents than seemingly innocuous measures (e.g., cognitive tests). We tested this assumption by asking 504 undergraduates to answer either surveys on trauma and sex or measures of cognitive ability, such as tests of vocabulary and abstract reasoning. Participants rated their positive and negative emotional reactions and the perceived benefits and mental costs of participating; they also compared their study-related distress with the distress arising from normal life stressors. Participants who completed trauma and sex surveys, relative to participants who completed cognitive measures, rated the study as resulting in higher positive affect and as having greater perceived benefits and fewer mental costs. Although participants who completed trauma and sex surveys reported slightly higher levels of negative emotion than did participants who completed cognitive measures, averages were very low for both groups, and outliers were rare. All participants rated each normal life stressor as more distressing than participating in the study. These results suggest that trauma and sex surveys pose minimal risk.

The effects of male attractiveness and sexual attitudes on women's risk perception.

This study examined the effects of male attractiveness, sexual attitudes, and victimization history on women's ratings of sexual risk. Women with more liberal sexual attitudes rated vignettes as less sexually risky than women with more conservative sexual attitudes. There was an interaction between situational risk and attractiveness, suggesting the relationship between attractiveness and sexual risk ratings varies across high and low situational risk. Findings emphasize the importance of using high and low risk situations to evaluate sexual risk perception and of investigating variables that may moderate women's risk perception.

A qualitative analysis of sexual victimization narratives.

The current study examined qualitatively 78 sexual victimization narratives to (a) investigate variability within Sexual Experiences Survey (SES) categories to determine whether these events shared contextual features, (b) investigate variability between SES categories to determine whether these events were contextually distinct, and (c) identify emerging contextual features of victimization experiences. Results revealed considerable variation in both within- and between-SES severity categories. Qualitative analysis also identified several emerging contextual features of victimization narratives, such as the after-party situation. Findings suggest that qualitative research may expose contextual variability in sexual victimization experiences not currently captured by quantitative measures of sexual victimization.

Arm use after left or right hemiparesis is influenced by hand preference.

BACKGROUND AND PURPOSE: Despite strong evidence for hand preference and its impact on motor performance, its influence on stroke rehabilitation has not been routinely considered. Previous research demonstrates that patients with hemiparetic stroke use their ipsilesional, nonparetic arm 5 to 6 times more frequently than their paretic arm, but it is unknown if such use varies with laterality of hemiparesis. The purpose of our study was to determine if the right arm is used more frequently in right-handed patients with stroke. METHODS: We assessed relative use of the right, left, and both arms with wrist accelerometers on patients with unilateral, paretic stroke matched for degree of paresis (12 with right hemisphere damage, 17 with left hemisphere damage) and 25 neurologically intact control participants as they performed the Arm Motor Ability Test. RESULTS: We showed: (1) ipsilesional arm use was greater after right hemisphere damage than left hemisphere damage; (2) the left hemisphere damage group used both arms together more often than the right hemisphere damage group but less often than the control group; and (3) both stroke groups used their contralesional, paretic arm to the same degree. CONCLUSIONS: These findings emphasize the influence of hand preference on arm use after stroke for the ipsilesional but not the contralesional arm. Although both stroke groups used their ipsilesional more than their contralesional arm, the difference was greater for the right hemisphere damage group who used their ipsilesional arm 4 times more frequently than their contralesional arm, whereas the left hemisphere damage group used their ipsilesional arm 2 times more frequently than their contralesional arm.
