RESUMO
BACKGROUND: Major depressive disorder (MDD) is the most prevalent mental health disorder worldwide, including among U.S. service members. In addition to evidence-based treatments, activity-based approaches have been shown to effectively treat depressive symptoms, particularly when they occur in the natural environment. METHODS: This study compared two activity-based interventions, Surf Therapy and Hike Therapy, on depression outcomes among 96 active duty service members with MDD. Participants were randomized to 6 weeks of Surf or Hike Therapy. Clinician-administered and self-report measures were completed at preprogram, postprogram, and 3-month follow-up. A brief depression/anxiety measure was completed before and after each activity session. RESULTS: Multilevel modeling results showed that continuous depression outcomes changed significantly over time (ps < .001). Although service members in Hike Therapy reported higher average depression scores than those in Surf Therapy, the trajectory of symptom improvement did not significantly differ between groups. Regarding MDD diagnostic status, there were no significant differences between the groups at postprogram (p = .401), but Surf Therapy participants were more likely to remit from MDD than were those in Hike Therapy at the 3-month follow-up (p = .015). LIMITATIONS: The sample consisted of service members, so results may not generalize to other populations. Most participants received concurrent psychotherapy or pharmacotherapy, and, although statistically accounted for, results should be interpreted in this context. CONCLUSIONS: Both Surf and Hike Therapies appear to be effective adjunctive interventions for service members with MDD. Research is needed to examine the effectiveness of these therapies as standalone interventions. TRIAL REGISTRATION: Clinical trials registration number NCT03302611; First registered on 05/10/2017.

Residential posttraumatic stress disorder (PTSD) research in military samples generally shows that in aggregate, PTSD symptoms significantly improve over the course of treatment but can remain at elevated levels following treatment. Identifying individuals who respond to residential treatment versus those who do not, including those who worsen, is critical given the extensive resources required for such programs. This study examined predictors of treatment response among 282 male service members who received treatment in a U.S. Department of Defense residential PTSD program. Using established criteria, service members were classified as improved, indeterminate (referent), or worsened in terms of self-reported PTSD symptoms. Multinomial logistic regression results showed that for PTSD symptoms, higher levels of pretreatment PTSD symptom severity were associated with significantly lower odds of being in the improved group, adjusted odds ratio (aOR) = 0.955, p = .018. In addition, service members who completed treatment were significantly more likely to be in the improved group, aOR = 2.488, p = .048. Longer average pretreatment nightly sleep duration, aOR = 1.157, p = .035, and more severe pretreatment depressive symptoms, aOR = 1.109, p = .014, were associated with significantly higher odds of being in the improved group. These findings reveal clinical characteristics better suited for residential PTSD treatment and highlight implications for comorbid conditions.

Psychological comorbidity, the co-occurrence of mental health disorders, is more often the rule than the exception among individuals with posttraumatic stress disorder (PTSD). Research shows that prevalence estimates for specific psychological disorders differ by gender; however, little is known about whether these patterns persist in the presence of a comorbid PTSD diagnosis. This study examined gender differences in prevalence estimates for conditions comorbid with PTSD using medical records for 523,626 active duty U.S. Sailors and Marines who entered the military over an 8-year period. Using chi-square tests of independence, we detected statistically significant gender differences for specific comorbid conditions in the subsample of 9,447 service members with a PTSD diagnosis. Women were more likely than men to have PTSD with comorbid adjustment, OR = 1.35; depressive, OR = 1.71; and generalized anxiety or other anxiety disorders, OR = 1.16, with the largest effects for eating, OR = 12.60, and personality disorders, OR = 2.97. In contrast, women were less likely than men to have a diagnosis of PTSD with comorbid alcohol use, OR = 0.69, and drug use disorders, OR = 0.72, with the largest effects for insomnia, OR = 0.42, and traumatic brain injury, OR = 0.17. No significant gender differences emerged for comorbid bipolar, obsessive-compulsive, panic/phobic, psychotic, or somatoform/dissociative disorders, ps = .029-.314. The results show gender differences in conditions comorbid with PTSD generally align with internalizing and externalizing dimensions. Differences in comorbidities with PTSD between women and men could have implications for treatment development and delivery.

Introduction: Exercise-based interventions have established benefits for the treatment of depression and other psychological outcomes; however, limited data exist evaluating psychological, social, and functional outcomes for exercise outdoors. Methods: The current study sought to expand knowledge about the breadth of effects following outdoor exercise interventions by using data from a randomized control trial comparing Surf and Hike Therapy among 96 U.S. active duty service members with major depressive disorder (MDD). Assessments examining psychological symptoms and functioning were completed before and after the 6-week programs, and 3 months following program completion. Participants also completed assessments before and after each exercise session. Multilevel modeling was used to determine whether psychological and functional outcomes (anxiety, positive and negative affect, resilience, pain, and physical and social functioning) improved for service members receiving Surf or Hike Therapy, and whether improvements differed by intervention. Results: Study findings showed improved anxiety (p < 0.001), negative affect (p < 0.001), psychological resilience (p = 0.013), and social functioning (p < 0.001) following program participation, with no differences by intervention. Positive affect, pain, and physical functioning did not significantly improve after the program. Within sessions, positive affect (p < 0.001) and pain (p = 0.036) changed, and to a greater extent for those in the Surf Therapy condition. Conclusion: Study results suggest that both Surf Therapy and Hike Therapy can improve psychological symptoms and social functioning impairments that commonly co-occur among service members with MDD, but Surf Therapy may provide enhanced immediate effects on positive affect and pain.

RESUMO
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.
