RESUMO
Insomnia is highly prevalent among military veterans, with rates nearly double that of civilian populations. Insomnia typically co-occurs with other psychological problems, including substance use (e.g. cannabis) and perceived stress. Much of the research focused on insomnia, stress and cannabis use explores cannabis as a sleep aid and a mechanism for stress relief. However, recent theoretical and empirical evidence suggests a dynamic interplay between insomnia, cannabis use and perceived stress, yet few longitudinal studies exist. Using a sample of 1105 post-9/11 veterans assessed over four time points across 12 months, we used latent difference score modelling to examine proportional change between insomnia, perceived stress and cannabis use. Results revealed a complex interplay between all three constructs. In particular, we show that higher prior levels of insomnia are associated with greater increases in perceived stress, and greater prior levels of stress are associated with greater increases in cannabis use. Perhaps more importantly, our results also point to cannabis use as a catalyst for greater increases in both stress and insomnia severity. Our results suggest there may be both benefits and costs of cannabis use among veterans. Specifically, for veterans who experience chronic sleep problems, perceived stress may become overwhelming, and the benefit of stress reduction from increased cannabis use may come at the cost of increasing insomnia symptomology.

Prior research with young adults has demonstrated clear associations between experiences of sexual assault, symptoms of posttraumatic stress disorder (PTSD), and alcohol use, but most studies have been cross-sectional or have not considered multiple theoretical pathways to understand these associations. Using six waves of data from a longitudinal cohort sample of 1,719 young adults, we examined associations among experiences of past-year sexual assault (i.e., rape, unwanted sexual touching, and physical intimidation in a sexual way), PTSD symptoms, and the frequency of binge drinking over time, allowing for the exploration of symptom-induced, interpersonal risk, and substance-induced pathways for male and female participants. For both male, ßs = 2.84 to 6.55, and female participants, ßs = 2.96 to 10.1, higher prior levels of PTSD symptoms were associated with larger increases in binge drinking over time. For female participants, higher prior levels of sexual assault were associated with larger increases in PTSD symptoms over time, ßs = 3.48 to 4.25, whereas for male participants, higher prior levels of past-year binge drinking were associated with decreases in PTSD symptoms over time, ßs = -2.75 to -0.53. Continued efforts are needed to prevent sexual assault among young adults and address PTSD symptoms among those who experience sexual assault. Interventions that target binge drinking are also needed for individuals who experience PTSD symptoms, especially young adults, to address potentially hazardous drinking before problems escalate and become chronic.

BACKGROUND: Sexual violence is a major public health concern that has a detrimental impact on mental health, physical health, and academic performance. College students represent a population that is at an increased risk of experiencing sexual violence. Alcohol use, and more specifically, heavy drinking during pregaming events, is associated with increased risk of sexual violence. Studies have demonstrated that protective behavioral strategies have effectively reduced heavy drinking and the risk of alcohol-related consequences, including sexual violence victimization. OBJECTIVES: This study aims to examine the association between experiences of sexual violence in college and subsequent use of pregaming protective strategies. RESULTS: Data from 468 college students (67% female, 33% male) were analyzed. Over 42% of participants reported experiencing sexual violence in college. While adjusting for pregaming frequency and sex, results revealed that those who reported experiencing sexual violence in college were significantly less likely to use pregaming protective behavioral strategies compared to those without such experiences. Specifically, survivors of sexual violence were less likely to report using the protective behavioral strategies of minimizing intoxication, as well as behaviors related to safety and familiarity (e.g., using a designated driver after pregaming). CONCLUSIONS: The findings have important implications for interventions aimed at empowering survivors of sexual violence. Future research should focus on understanding survivor's motives and mechanisms to use pregaming protective behavioral strategies to reduce the risk of re-victimization.
RESUMO
BACKGROUND: Pregaming is a high-risk drinking behavior that is associated with heavy drinking and negative alcohol-related consequences. College students may engage in pregaming for several reasons, including to enhance social experiences or cope with negative affect. Research shows that associations between drinking, social anxiety, and depression are multifaceted. However, our understanding of the complex associations of mental health symptoms with pregaming motives and behaviors remains limited. METHODS: This study examined heterogeneity in how pregaming motives, social anxiety, and depression associate with past 30-day pregaming variables (quantity, frequency, and negative consequences). We used latent profile analysis (LPA) in a sample of heavy-drinking university students (N = 479). RESULTS: LPA results indicated four profiles: mild/moderate social anxiety and depression symptoms, moderate motives (n = 285), minimal social anxiety and depression symptoms, low motives (n = 61), subclinical/elevated social anxiety and depression symptoms, high motives (n = 75), and clinically elevated social anxiety and depression symptoms, moderate motives (n = 58). The subclinical/elevated symptoms, high motives profile reported the highest pregaming frequency and consequences, including blackouts. Individuals in the clinically elevated symptoms, moderate motives profile reported more consequences than those in the minimal symptoms, low motives and mild/moderate symptoms, moderate motives profiles. Individuals in the minimal symptoms, low motives profile reported the fewest consequences. CONCLUSIONS: Among these students, social anxiety and pregaming motives were associated with more frequent pregaming and social anxiety and depression were associated with greater negative consequences. Interventions that target pregaming-specific motives among students with mental health symptoms may be warranted to reduce this risky behavior and associated drinking-related harm.
RESUMO
Trauma-related guilt, or a belief that one should have felt, thought, or acted differently during a traumatic event in which someone's life or physical integrity was threatened, has been consistently associated with mental health disorders such as posttraumatic stress disorder (PTSD). Theories of trauma-related guilt suggest that some avoidant coping behaviors, such as problematic alcohol use, are crucial pathways connecting trauma-related guilt to PTSD but have not been thoroughly investigated. The present study uses data from a longitudinal cohort of veterans to examine two models: the first assessed problematic alcohol use as a mechanism linking trauma-related guilt and PTSD. The second explored PTSD as a mechanism linking trauma-related guilt to problematic alcohol use. Results indicated that problematic alcohol use was a significant mechanism linking global guilt and guilt cognitions with PTSD. Further, results indicated that PTSD was a significant mechanism linking global guilt and distress with problematic alcohol use. Results of our study indicate that alcohol use is a key construct that has been overlooked in the trauma-related guilt literature, despite the high prevalence of co-occurring PTSD and alcohol use (and alcohol use disorder). Targeting trauma-related guilt during integrated treatments for PTSD and alcohol use disorder may be particularly important for veterans.

BACKGROUND: Post-traumatic stress disorder (PTSD) and alcohol use disorder (AUD) are highly prevalent, and co-occurring among post-9/11 veterans. Mobile health (mHealth) applications, specifically those focused on mindfulness-based techniques, may be an effective avenue to intervene with veterans who cannot or will not seek care at traditional in-person settings. Thus, to address areas of improvement in mHealth for veterans, we developed Mind Guide and prepared it for testing in a pilot randomized controlled trial (RCT) with veterans. METHODS: We have completed phase 1 (treatment development) and Phase 2 (beta test) of our mobile mHealth app, Mind Guide. In this paper we describe the methods for Phase 1 as well as results for our beta test (n = 16; inclusion criteria included screen for PTSD, AUD, a post-9/11 veteran, and not currently receiving treatment) for Mind Guide as well as outline procedures for our pilot RCT of Mind Guide (Phase 3). The PTSD Checklist, self-reported alcohol use, the Perceived Stress Scale, Penn Alcohol Craving Scale, and the Emotion Regulation Questionnaire were used. RESULTS: Results of our beta test of Mind Guide show promising past 30 day effects on PTSD (d = -1.12), frequency of alcohol use (d = -0.54), and alcohol problems (d = -0.44), and related mechanisms of craving (d = -0.53), perceived stress (d = -0.88), and emotion regulation (d = -1.22). CONCLUSION: Our initial beta-test of Mind Guide shows promise for reducing PTSD and alcohol related problems among veterans. Recruitment is ongoing for our pilot RCT in which 200 veterans will be recruited and followed up for 3 months. CLINICALTRIALS: gov Identifier: NCT04769986.
