The Sexual Harassment–Suicide Connection in the U.S. Military: Contextual Effects of Hostile Work Environment and Trusted Unit Leaders

Sexual harassment has been associated with suicidal behaviors, and with the rise in suicides in the U.S. military, sexual harassment's role in suicide has been of growing interest. Lacking are studies that examine group‐ or unit‐level variables in the relationship of sexual harassment to suicidal behaviors (thoughts, plans, and attempts). In this study, survey data from soldiers (12,567 soldiers in 180 company‐sized units) who completed the Unit Risk Inventory administered during calendar year 2010 were analyzed using hierarchical linear modeling. At the individual level, sexual harassment was associated with a fivefold increase for risk of suicide. Reporting that leaders could be trusted was associated with a decreased suicide risk by about one‐third. There was no statistically significant interaction between sexual harassment and trusted leaders in predicting the suicidal behaviors. At the group level, units or companies having higher levels of sexual harassment also had soldiers three times more at risk for suicide. A cross‐leveling effect was also observed: Among units having higher levels of sexual harassment, the negative correlation (buffering effect of unit leaders on suicidal behaviors) was diminished. Implications of findings for preventing sexual harassment and suicide risk are discussed.     

Restrictions in working memory capacity during parachuting: a possible cause of ‘no pull’ fatalities

Working memory capacity of novice and experienced parachutists was compared under three conditions: prior to exiting the aircraft, on landing and during a control, non‐jumping day. Analysis of the operation span task revealed significant impairments in both storage and processing capacities of working memory prior to jumping. Storage capacity continued to be impaired in novice parachutists on landing whilst experienced parachutists showed full recovery. Neither group showed impairment in processing capacity on landing. Significant increases in heart rate were found for both groups in the jump and landing conditions compared to baseline but no differences existed between novices and experienced parachutists. Initial analyses support processing efficiency theory and suggest that cognitive processing may be slowing down during a jump. However, post hoc analysis of incorrect responses suggest that executive function may actually become disrupted. The results are reviewed in the context of ‘no pull’ parachuting fatalities.

How to Know That Time Travel Is Unlikely Without Knowing Why

What's the point of time travel? Not to change the past; no matter how carefully a time traveler plans, all of her attempts to change the past end in failure. Paul Horwich has argued that the implausibility of such failures gives us reason to doubt that there will be frequent time travel to the local past. I defend a modified version of Horwich's argument and show how we might gain evidence about the chance of there being frequent time travel in the future without having any information that explains why that chance value obtains.     

Combat Exposure and Risk for Suicidal Thoughts and Behaviors Among Military Personnel and Veterans: A Systematic Review and Meta‐Analysis

Due to seemingly mixed empirical results, questions persist about the possible role of deployments and combat exposure. We conducted a narrative review and meta‐analysis of 22 published studies to integrate findings regarding the relationship of deployment‐related predictors (i.e., deployment, deployment to a combat zone, combat experience, and exposure to specific combat events) with suicide‐related outcomes (i.e., suicide ideation, attempt, and death). Across all predictors and outcomes, the combined effect was small and positive, r = .08 [0.04, 0.13], and marked by significant heterogeneity, I² = 99.9%, Q(21)=4880.16, p < .0001, corresponding to a 25% increased risk for suicide‐related outcomes among those who have deployed. Studies examining the relationship between exposure to killing and atrocities (k = 5) showed the largest combined effect, r = .12 [0.08, 0.17], and less heterogeneity, I² = 84.4%, Q(4)=34.96, p < .0001, corresponding to a 43% increased risk for suicide‐related outcomes among those exposed to killing or atrocity. Implications for theory, research, and clinical practice are discussed.     

Impact of a Suicide‐Specific Intervention within Inpatient Psychiatric Care: The Collaborative Assessment and Management of Suicidality

A growing body of literature indicates that suicidal patients differ from other psychiatric patients with respect to specific psychological vulnerabilities and that suicide‐specific interventions may offer benefits beyond conventional care. This naturalistic controlled‐comparison trial (n = 52) examined outcomes of intensive psychiatric hospital treatment (mean length of stay 58.8 days), comparing suicidal patients who received individual therapy from clinicians utilizing the Collaborative Assessment and Management of Suicidality (CAMS) to patients whose individual therapists did not utilize CAMS. Propensity score matching was used to control for potential confounds, including age, sex, treatment unit, and severity of depression and suicidality. Results showed that both groups improved significantly over the course of hospitalization; however, the group receiving CAMS showed significantly greater improvement on measures specific to suicidal ideation and suicidal cognition. Results are discussed in terms of the potential advantages of treating suicide risk with a suicide‐specific intervention to make inpatient psychiatric treatment more effective in reducing risk for future suicidal crises.
