Objective Simultaneous use of alcohol in combination with cannabis ("co-use") is common among young adults, and associated with myriad consequences. Yet no studies have examined how co-use may confer vulnerability for sexual assault (SA). Further, though both co-use and SA commonly occur in social settings, there have been no examinations of the role that co-use may play in the broader social context that leads to assault risk. This was the objective of the present study. Method In a community sample of young adult women, (N = 174; Mage = 22.6), we examined risk pathways to SA, guided by Routine Activities Theory (Mustaine & Tewksbury, Criminal Justice Review, 2002, 27, 89). Using a longitudinal burst design with 27 daily assessments across 1 year, women reported on their own and others' alcohol, cannabis, and co-use, and on social context and assault experiences. Results Multilevel path model results showed alcohol and cannabis co-use to confer unique risk for SA, above and beyond the influence of use of either substance alone. Intoxication and components of the co-use social context (proximity to offenders) mediated this risk. Importantly, we observed a key role for co-use by others within the social context in assault risk. Conclusions This study adds to the literature by providing a nuanced and contextual account of how cannabis-alcohol co-use may lead to assault vulnerability in young adult women. Findings underscore the need for intervention efforts that expand their focus to include the broader social context, and the role that the use and co-use behaviors of others may play within this context.

Thus, cultivating employees' experiences of gratitude represents an important imperative in modern organizations that rely on teamwork and collaboration to achieve organizational goals. Yet, today's workplace presents a complex array of demands that make it difficult for employees to fully attend to and appreciate the various benefits they receive at work. As such, gratitude is difficult for employers to promote and for employees to experience. Despite these observations, the role of attention and awareness in facilitating employees' feelings of gratitude is largely overlooked in the extant literature. In this study, we examined whether one notable form of present moment attention, mindfulness, may promote helping behavior by stimulating the positive, other-oriented emotion of gratitude. Across two experimental studies, a semiweekly, multisource diary study, and a 10-day experience sampling investigation, we found converging evidence for a serial mediation model in which state mindfulness, via positive affect and perspective taking, prompts greater levels of gratitude, prosocial motivation, and, in turn, helping behavior at work. We discuss the theoretical and practical implications of our investigation, as well as avenues for the future research.

Thus, understanding brain responses to food cues when satiated has important implications for weight control interventions. We used the late positive potential (LPP, a component of the event-related potentials (ERP) indexing motivational relevance) to determine the extent to which satiety affects brain responses to images of highly palatable foods (high-fat, high-sugar), high and low motivationally relevant (pleasant, unpleasant) and neutral stimuli in a sample of obese (body mass index [BMI] ≥ 30 kg/m2) and lean (BMI less then 25 kg/m2) individuals. Satiated individuals (N = 55, 21 with BMI ≥ 30 kg/m2) were fed a nutritional drink prior to the experimental session and were individually matched with 55 unsatiated individuals who saw the same images during a passive viewing task. Satiety did not affect LPP response to food-related or motivationally relevant cues in either BMI less then 25 kg/m2 or BMI ≥ 30 kg/m2 individuals (p = .6). Irrespective of satiety, all participants showed larger LPPs as a function of the images' motivational relevance. There were no differences in LPP amplitude between BMI less then 25 kg/m2 and BMI ≥ 30 kg/m2 individuals for any picture category, including food. However, within-group comparisons showed that BMI less then 25 kg/m2 individuals had larger LPPs to low motivationally relevant pleasant images than to food-related cues (p less then .001); this difference was not significant for BMI ≥ 30 kg/m2 individuals. Although satiety does not affect LPP responses to food-related cues, these results highlight the importance of evaluating reactivity to food-related cues in relation to other motivationally relevant stimuli.

Further explication of PTSD symptom effects on future SUD risk will likely promote intervention development and refinement while offsetting SUD risk. Accordingly, In this study we explored the prospective associations between PTSD symptom clusters, symptoms, and future SUD risk and use of specific drug classes. Returning veterans (N = 1,295; Mage = 42.3, SD = 9.89; 51% female; 66.8% White) completed structured diagnostic interviews to assess PTSD symptoms and self-report measures of substance use 14-36 months later (M = 24.59, SD = 2.97). Hyperarousal and reckless/self-destructive symptoms specifically predicted future high-risk drug use and binge drinking behavior, and avoidance of internal stimuli (i.e., of trauma memories, thoughts, and feelings) differentiated individuals classified as high-risk for alcohol use based on their AUDIT total score. Further, negative alterations in cognition and mood predicted future opioid (i.e., nightmares) and stimulant use (i.e., flashbacks), whereas concentration difficulties were inversely associated with future binge drinking. U18666A This longitudinal study identified prospective and enduring associations between specific PTSD symptom clusters, symptoms, and future high-risk substance use patterns among returning veterans. Accordingly, careful assessment of specific PTSD criteria and differential motivations for substance use is warranted, along with tailored interventions to offset risk for opioid, stimulant, and alcohol use among returning veterans.
