The Effects of Sexual Violence Victimization on Perceived Peer Norms and Social Barriers to Bystander Intervention Among High School Students.

The experience of sexual victimization may lead to increased threat-biased information processing, including increased perceptions of peer attitudes that condone sexual violence. The perception that peers generally condone sexual violence may in turn inhibit survivors of sexual violence from intervening to address risk for harm among their peers. To assess this possibility, the present study examined the direct and indirect association between sexual victimization by a romantic partner, perceived peer rape myth acceptance (RMA), perceived social barriers to bystander intervention, and bystander behaviors over 2-month follow-up in a sample of 843 high school students. Multiple regression path analyses revealed a sequence of positive associations between sexual victimization, perceived peer RMA, and perceived social barriers to bystander intervention, respectively. These direct associations to be significant among girls, but not boys, and revealed an additional negative direct association between perceived social barriers to bystander intervention and bystander behavior over 2-month follow-up among girls. Furthermore, sexual victimization was indirectly associated with decreased bystander behaviors among girls through perceived peer RMA and perceived social barriers to bystander intervention, respectively. Taken together, the current findings highlight the importance of addressing misperceptions of peer norms among survivors of sexual violence in bystander intervention programs.

The Prospective Influence of Perceived Social Norms on Bystander Actions Against Sexual Violence and Relationship Abuse: A Multiple Mediation Model.

The present study assessed support for an innovative model of the direct and indirect paths through which perceived peer norms regarding the prevalence and acceptability of sexual violence (SV) and relationship abuse (RA) may influence the decisional process leading to bystander intervention. Analyses included baseline and 6-month follow-up data collected from a large sample of high school students (N = 2,303) across 27 schools in the Northeastern United States. Path analyses were conducted to test a multiple mediation model of the direct and indirect associations among the sequential predictors of perceived descriptive and injunctive norms, personal attitudes, abuse perceptions, risk recognition, and dependent measures of bystander behaviors at baseline and 6-month follow-up. Higher perceptions of the prevalence (descriptive norms) and acceptability (injunctive norms) of SV and RA among peers were associated with more accepting personal attitudes toward SV and RA, which were associated with lower abuse perceptions and risk recognition. Furthermore, lower abuse perceptions and risk recognition were associated with decreases in bystander behaviors at both time points. Mediational analyses revealed several significant indirect paths through which higher perceptions of descriptive and injunctive norms contributed to decreases in bystander behavior. Findings provide novel evidence of the prospective influence of perceived norms on bystander intervention behavior in situations of SV and RA.

The mediating role of school connectedness in the associations between dating and sexual violence victimization and substance use among high school students.

Dating and sexual violence victimization affect a significant portion of teenagers and result in a wide array of negative health and behavioral outcomes, including increased alcohol and drug use. In some cases, students who have been victimized may develop feelings of being unsupported by or disconnected from peers and adults in their school community, placing them at even higher risk for negative health outcomes. Using a prospective design, the present study sought to explore this possibility by examining the direct and indirect associations between dating violence (DV) and sexual violence (SV) victimization, school connectedness, and alcohol and marijuana use at baseline (T1) and 2-month follow-up (T2) in a sample of high school students (N = 1752). Results of multiple regression analyses supported a hypothesized mediation model of these associations; both forms of victimization were positively associated with heavy drinking at T1 and marijuana use at T1 and T2, and negatively associated with school connectedness. Furthermore, school connectedness was negatively associated with both forms of substance use at T1 and T2, and partially mediated the effects of DV and SV victimization on heavy drinking at T1, and marijuana use at T1 and T2. These findings elucidate the importance of addressing intermediary cognitive processes such as perceptions of school connectedness in order to improve health and functional outcomes among high school victims of dating and sexual violence.

Increased Working Memory Load in a Dual-Task Design Impairs Nonverbal Social Encoding in Children with High and Low Attention-Deficit/Hyperactivity Disorder Symptoms.

Children with attention-deficit/hyperactivity disorder (ADHD) are known to have difficulty with peer relations, though the mechanisms by which these children struggle with interpersonal relationships are not well known. The current study examined the relation between working memory (WM) and the encoding of nonverbal social cues using a dual-task paradigm tested in children with High and Low ADHD symptoms. A total of 40 children were recruited (20 High ADHD; 20 Low ADHD) and completed computerized tasks of social encoding and WM in both single- and dual-task conditions. A series of repeated measures mixed-model ANOVAs revealed that both children with High ADHD and Low ADHD performed significantly worse during the dual-task condition compared to the single task conditions. Also, children with High ADHD had significantly lower performance than Low ADHD children on task-based social encoding and WM. This study supports the role of WM in nonverbal social encoding in children.

Health and demographic discriminators of an insomnia identity and self-reported poor quantitative sleep.

OBJECTIVES: To identify factors that most saliently characterize the profile of individuals who complain of chronic insomnia, with or without quantitative sleep impairment. DESIGN: Community-dwelling adults reported on their demographics and functioning via questionnaires and completed 2 weeks of sleep diaries. SETTING: Shelby County in the Memphis, TN, area. PARTICIPANTS: Population-based sample, stratified by sex and age to maximally represent sleep and health across the life span. MEASUREMENTS: Participants were classified into 4 groups according to whether or not they endorsed a chronic insomnia complaint and whether they demonstrated good or poor quantitative sleep on diaries. Discriminant analysis determined which of the following variables significantly maximized spread among the sleep groups: age, sex, race, body mass index, household education, number of medications, frequency of substance use, number of medical conditions, depression, anxiety, fatigue, daytime sleepiness, and daytime insomnia impact. RESULTS: On the most powerful discriminant function, participants with more medical conditions, greater depression and anxiety, and older age were more likely to complain of chronic insomnia than to not complain and, within these levels, to have poor rather than good quantitative sleep. A second function found African Americans particularly likely to be noncomplaining poor sleepers compared to Whites. CONCLUSIONS: Findings make progress in clarifying the profile of individuals who self-identify as having chronically poor sleep. Notably, general depression and anxiety surpassed sleep-related daytime impairment measures in discriminating complaining sleepers. Negativistic self-appraisals driving diffuse psychological symptoms may thus be viable intervention targets for reducing persistent insomnia complaints independently of sleep-specific concerns.

The Causal Influence of Perceived Social Norms on Intimate Partner Violence Perpetration: Converging Cross-Sectional, Longitudinal, and Experimental Support for a Social Disinhibition Model.

Across three studies, we develop a model of the direct and indirect paths through which the perceived prevalence (perceived descriptive norms [PDN]) of intimate partner violence (IPV) among peers may influence individuals' likelihood of engaging in IPV. Study 1 replicated and extended previous cross-sectional research by demonstrating a positive longitudinal association between PDN and subsequent IPV perpetration. Study 2 further showed the influence of PDN on IPV perpetration to be mediated through its relation to perceived peer acceptance of IPV (perceived injunctive norms [PIN]), which in turn predicted personal IPV acceptance. Study 3 built on this model using an experimental paradigm to show that increasing PDN leads to corresponding increases in PIN and, in turn, personal IPV acceptance, which both predicted IPV perpetration. Furthermore, the effects of PIN on personal IPV acceptance and IPV propensity were strongest for dominance-oriented individuals. Results bear important implications for social norms-based interventions for IPV.

Intraindividual sleep variability and its association with insomnia identity and poor sleep.

OBJECTIVE: Insomnia identity refers to the conviction that one has insomnia, which can occur independently of poor sleep. Night-to-night variability in sleep (termed intraindividual variability [IIV]) may contribute to insomnia identity yet remain undetected via conventional mean analyses. This study compared sleep IIV across four subgroups: noncomplaining good sleepers (NG), complaining poor sleepers (CP), complaining good sleepers (CG), and noncomplaining poor sleepers (NP). METHODS: This study analyzed 14 days of sleep diary data from 723 adults. Participants were classified according to presence/absence of a sleep complaint and presence/absence of poor sleep. A 2 × 2 multivariate analysis of covariance (MANCOVA) was performed to explore differences on five measures of sleep IIV: intraindividual standard deviation in total sleep time (iSD TST), sleep onset latency (iSD SOL), wake after sleep onset (iSD WASO), number of nightly awakenings (iSD NWAK), and sleep efficiency (iSD SE). RESULTS: MANCOVA revealed significant main effects of poor sleep, sleep complaint, and their interaction on sleep IIV. Poor sleepers exhibited greater IIV across all sleep parameters compared to good sleepers. Similarly, individuals with a sleep complaint exhibited greater IIV compared to individuals with no complaint. The interaction revealed that iSD SOL was significantly greater among CP than NP, and iSD NWAK was significantly greater among CG than NG. CONCLUSIONS: Greater night-to-night variability in specific sleep parameters was present among complaining versus noncomplaining sleepers in good and poor sleep subgroups. These findings suggest certain aspects of sleep consistency may be salient for treatment-seeking individuals based on their quantitative sleep status.

Unmet social support needs among college students: Relations between social support discrepancy and depressive and anxiety symptoms.

Social support is a widely studied construct due to its associations with physical and emotional well-being outcomes (Uchino, 2006). However, little research examines the context within which receiving support may be helpful (Picard, Lee, & Hunsley, 1997). Whereas examinations of support adequacy are present in the literature (e.g., Song et al., 2012), limited research considers the difference between support needs and support received when the 2 are separated as distinct constructs. The current study consisted of 428 undergraduate college students and examined how the relation between social support needs and received social support relates to depressive and anxiety symptoms via a statistical approach suggested for need-actual discrepancy analysis (polynomial multiple regression, PMR, with response surface analysis; Edwards, 1994; Shanock, Baran, Gentry, Pattison, & Heggestad, 2010). Results indicated that greater discrepancy between needed support and received support was related to greater depressive, but not anxiety, symptoms. Specifically, when emotional support needs exceeded emotional support received, depressive symptoms tended to be highest. Moreover, perceptions of needed support were significantly greater than perceptions of received support, suggesting that college students in general perceive receiving less support than they need, and this discrepancy is related to greater depressive symptoms.

Literacy-Adapted Cognitive Behavioral Therapy Versus Education for Chronic Pain at Low-Income Clinics: A Randomized Controlled Trial.

Background: Chronic pain is common and challenging to treat. Although cognitive behavioral therapy (CBT) is efficacious, its benefit in disadvantaged populations is largely unknown. Objective: To evaluate the efficacy of literacy-adapted and simplified group CBT versus group pain education (EDU) versus usual care. Design: Randomized controlled trial. (ClinicalTrials.gov: NCT01967342). Setting: Community health centers serving low-income patients in Alabama. Patients: Adults (aged 19 to 71 years) with mixed chronic pain. Interventions: CBT and EDU delivered in 10 weekly 90-minute group sessions. Measurements: Self-reported, postintervention pain intensity (primary outcome) and physical function and depression (secondary outcomes). Results: 290 participants were enrolled (70.7% of whom were women, 66.9% minority group members, 72.4% at or below the poverty level, and 35.8% reading below the fifth grade level); 241 (83.1%) participated in posttreatment assessments. Linear mixed models included all randomly assigned participants. Members of the CBT and EDU groups had larger decreases in pain intensity scores between baseline and posttreatment than participants receiving usual care (estimated differences in change scores-CBT: -0.80 [95% CI -1.48 to -0.11]; P = 0.022; EDU: -0.57 [CI, -1.04 to -0.10]; P = 0.018). At 6-month follow-up, treatment gains were not maintained in the CBT group but were still present in the EDU group. With regard to physical function, participants in the CBT and EDU interventions had greater posttreatment improvement than those receiving usual care, and this progress was maintained at 6-month follow-up. Changes in depression (secondary outcome) did not differ between either the CBT or EDU group and the usual care group. Limitations: Participants represented a single health care system. Self-selection bias may have been present. Conclusion: Simplified group CBT and EDU interventions delivered at low-income clinics significantly improved pain and physical function compared with usual care.

Social Norms for Intimate Partner Violence: A Replication With College Students.

This study replicated prior research on college students' perceived descriptive norms (i.e., prevalence estimates) for intimate partner violence (IPV). In this study, male and female college students were instructed to estimate the prevalence of physical forms of IPV for "typical students" of their same gender on campus. Perpetrators of IPV-both male and female-made higher estimates than nonperpetrators. When compared to actual prevalence rates, both perpetrators and nonperpetrators overestimated the prevalence of IPV on campus. Findings have implications for prevention programs that address social norms.

The role of perceived sleep norms in subjective sleep appraisals and sleep-related illness behavior.

The present investigation sought to extend extant research on subjective sleep complaints by examining their relation to perceived sleep norms. Results from two studies showed that individuals' distress and illness behavior in response to symptoms of fatigue and non-restorative sleep was influenced by their perceptions of peer norms for those symptoms. Individuals who believed they experienced a greater degree of fatigue and non-restorative sleep than their peers reported more distress arising from those symptoms, and were also more likely to seek social support and medical treatment for them. Furthermore, participants who scored higher in neuroticism were more likely to believe they experienced worse fatigue and non-restorative sleep than their peers, and thus reported higher symptom-related distress, and higher likelihood of engaging in illness behaviors. These results provide preliminary evidence of the clinical relevance of perceived norms in the way individuals respond to and manage sleep related problems.

Bystander interventions for sexual assault and dating violence on college campuses: Are we putting bystanders in harm's way?

OBJECTIVE: The present study investigated the well-being of bystanders who witness and intervene in sexual assault and dating violence situations on campus. PARTICIPANTS: Participants were 321 young men and women from a large university in the southeastern United States. METHODS: Participants completed a survey at the end of the Spring semester of 2015 about risky situations they had witnessed, with follow-up questions about their responses to the situations (eg, whether they intervened or not) and feelings about their responses. Participants also completed standardized measures of posttraumatic stress disorder and depression. RESULTS: Over 90% of the participants reported witnessing at least 1 of the risky events presented to them, and approximately 50% reported intervening in events. Intervening was associated with positive feelings, but traumatic stress symptoms were related to witnessing events and intervening. CONCLUSIONS: Results have direct implications for developing appropriate training programs for bystander intervention programs on college campuses.

Perceived Social Norms for Intimate Partner Violence in Proximal and Distal Groups.

This study investigated students' perceived descriptive social norms for intimate partner violence (IPV) among proximal and distal groups at college. Male and female college students estimated the prevalence rates for IPV among same-sex friends (proximal group) and same-sex "typical students" (distal group). In separate regression equations for men and women, perceived estimates of IPV rates for same-sex friends, but not estimates for same-sex typical students, were positively related with the participants' own IPV behaviors. Findings have important implications for IPV prevention and intervention programs for college students.

Social norms for intimate partner violence.

This study investigated perceived descriptive norms (i.e., perceived prevalence) for intimate partner violence (IPV) among college students. Male and female college students were asked to estimate the prevalence of IPV for same-sex "typical students" on their campus. Perpetrators of IPV made higher estimates than nonperpetrators. Both perpetrators and nonperpetrators overestimated the prevalence of IPV when compared to actual prevalence rates. Findings lend support for using social-norms-based prevention programs on college campuses.

Social norms for intimate partner violence in situations involving victim infidelity.

The present study investigated perceived descriptive norms (i.e., perceived prevalence) for male-to-female intimate partner violence (IPV) following victim infidelity (i.e., girlfriend had sex with another man). While watching a video-taped vignette of a young, dating couple in an argument that escalated to male-to-female violence, male participants were asked various questions to assess perceived descriptive norms at several time points during the escalating argument. Half of the participants were told that the victim in the video was unfaithful. Results suggested that while participants did believe that it was much more common for their male friends and for typical male students to aggress against unfaithful girlfriends compared to faithful girlfriends, these differences were less pronounced as the aggression intensified. When testing whether perceived norms for IPV were related to participants' purported risk of engaging in IPV, a clear pattern appeared: For the no-infidelity condition, IPV perceived norms for male friends and perceived norms for typical male students were each significantly related to participants' likelihood of engaging in IPV, such that the higher the estimated norm, the higher the participants' risk. However, for the infidelity condition, only perceived norms for male friends were related to the risk of engaging in IPV. Findings have important implications for social norms-based intervention and prevention programs for IPV on college campuses.
