RESUMEN

INTRODUCTION: Sexual assault in the U.S. Military is a serious concern. Recruiting representative samples of service members to participate in sexual assault research is essential for understanding the scope of the problem and generating data that can inform prevention and intervention efforts. Accordingly, the current study aims to examine response and completion rates of an anonymous survey of sexual assault and alcohol use among active duty sailors aged 18 to 24 with the overarching goal of achieving a representative sample and informing future recruitment efforts. MATERIALS AND METHODS: This study was approved by the Institutional Review Board at the Naval Health Research Center. The study involved an anonymous survey of sexual assault and alcohol use among 612 active duty sailors aged 18 to 24. Since 79.6% of Navy service members are men and 20.4% are women, women were oversampled to achieve sufficient representation. Survey invitations were emailed to 12,031 active duty sailors: 64.3% (n = 7,738) men and 35.7% (n = 4,293) women. RESULTS: Response rates were disproportionate, with 3.0% (n = 234) of male and 8.8% (n = 377) of female sailors responding to the study invitation. Survey completion rates, however, were similar between male and female sailors (81.2% and 80.1% for male and female personnel, respectively). CONCLUSION: Results demonstrated that female sailors were significantly more likely than male sailors to participate in a study of sexual assault and alcohol use. However, once enrolled in the study, male and female sailors completed the 234-item questionnaire at a similar rate. Study findings highlight the challenges of engaging male service members in sexual assault-related research. Despite the disproportionately high representation of men in the military, sexual assault researchers may need to sample according to the overall distribution of gender in the military or perhaps even oversample men to achieve a representative sample.

RESUMEN

Background: Sexual assault and alcohol use are significant public health concerns, including for the United States (US) military. Although alcohol is a risk factor for military sexual assault (MSA), research on the extent of alcohol-involvement in MSAs has not been synthesised.Objective: Accordingly, this scoping review is a preliminary step in evaluating the existing literature on alcohol-involved MSAs among US service members and veterans, with the goals of quantifying the prevalence of alcohol-involved MSA, examining differences in victim versus perpetrator alcohol consumption, and identifying additional knowledge gaps.Method: In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for Scoping Reviews, articles in this review were written in English, published in 1996 or later, reported statistics regarding alcohol-involved MSA, and included samples of US service members or veterans who experienced MSA during military service.Results: A total of 34 of 2436 articles identified met inclusion criteria. Studies often measured alcohol and drug use together. Rates of reported MSAs that involved the use of alcohol or alcohol/drugs ranged from 14% to 66.1% (M = 36.94%; Mdn = 37%) among servicemen and from 0% to 83% (M = 40.27%; Mdn = 41%) among servicewomen. Alcohol use was frequently reported in MSAs, and there is a dearth of information on critical event-level characteristics of alcohol-involved MSA. Additionally, studies used different definitions and measures of MSA and alcohol use, complicating comparisons across studies.Conclusion: The lack of event-level data, and inconsistencies in definitions, measures, and sexual assault timeframes across articles demonstrates that future research and data collection efforts require more event-level detail and consistent methodology to better understand the intersection of alcohol and MSA, which will ultimately inform MSA prevention and intervention efforts.

A total of 34 of 2436 articles identified met inclusion criteria. Studies often measured alcohol and drug use together. Rates of reported military sexual assaults that involved the use of alcohol or alcohol/drugs ranged from 14% to 66.1% (M = 36.94%; Mdn = 37%) among servicemen and from 0% to 83% (M = 40.27%; Mdn = 41%) among servicewomen.More precise prevalence estimates of the intersection between alcohol and military sexual assault were limited due to inconsistencies in the definitions of sexual assault and alcohol use, measures of sexual assault and alcohol use, and timeframe for reporting across studies.Future research should standardise the measures, definitions, and timeframes of sexual assault and alcohol-involvement to allow for a more precise estimation of alcohol-involved military sexual assault. Furthermore, event-level data is needed including amount and timeframe of alcohol consumption, relationship between victim and perpetrator, location of alcohol consumption and military sexual assault, and whether the assault was opportunistic or facilitated, to inform military sexual assault prevention and intervention efforts in the military.

RESUMEN

Sexual assault and harassment are significant problems that begin early in the lifespan. The current study sought to understand the contextual factors that influence the implementation of school-wide sexual assault prevention programs in middle schools that focus on fostering community norms change. The Consolidated Framework for Implementation Research (CFIR) is a menu of constructs arranged across 5 domains that assists stakeholders in assessing and identifying site-specific determinants of successful intervention implementation. In the present study, researchers conducted a series of 10 interviews with middle school stakeholders (i.e., principals, guidance counselors, teachers) to document characteristics inside and outside of the school environment (i.e., cultural norms, relative priority, prior interventions, implementation climate) relevant to the implementation of prevention programming, using the CFIR as a guiding framework for analysis. Whereas schools recognized the importance of implementing violence prevention programming, stakeholders reported several other competing demands (i.e., time, resources) that make it difficult to implement rigorous programming without support from an outside agency/team. Community agencies and research teams hoping to implement violence prevention in middle schools can benefit from using stakeholder interviews grounded in the CFIR model to gain a better awareness of the school- and community-specific factors that are likely to influence successful implementation of violence prevention programs in middle schools.

RESUMEN

The present study recruited psychologically healthy individuals and individuals with clinically-severe Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition diagnoses, including generalized anxiety disorder, major depressive disorder, social anxiety disorder, posttraumatic stress disorder, panic disorder, persistent depressive disorder, and specific phobia. During the course of a structured clinical interview, 200 individuals provided continuous electrocardiogram and impedance cardiography data. Of these N = 150 were used for exploratory analyses and N = 50 for confirmatory analyses. From these time series, we modeled heart period (i.e. interbeat interval), pre-ejection period, respiratory sinus arrhythmia, and respiration rate. The group iterative multiple model estimation (GIMME) model was used to generate group and individual-level network models which, in turn, were used to conduct unsupervised classification of individual-level models into subgroups. Four subgroups were identified, comprising N = 22, N = 25, N = 26, and N = 61 individuals, with an additional 16 individuals left unclassified. The subgroup models were then used to estimate directed network models, from which out-degree and in-degree centrality were estimated for each group. Two groups, Group 2 and Group 4 exhibited elevated symptoms of depression and anxiety relative to the remaining sample. However, only one of these, Group 2, exhibited additional physiological risk features, including a significantly elevated average heart rate, and significantly reduced parasympathetic regulation (measured via respiratory sinus arrhythmia). We discuss the implications for utilizing network models for conducting systems-level analyses of physiological systems in clinically-distressed and psychologically healthy individuals.
