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. 相似文献

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.

The aims of this study were to analyze whether positive and negative affect, social support, and loneliness are factors longitudinally related to suicide ideation in the general population in different age groups. A total of 2,392 individuals from a nationally representative sample of the Spanish general population were evaluated in 2011–2012 and in 2014–2015. After including relevant control variables in the analyses, lower positive affect was prospectively related to ideation in 18‐ to 59‐year‐old individuals, whereas feelings of loneliness were related to ideation in 60‐year‐and‐older individuals. Social support was not associated with suicide ideation in any age group. These results are in line with the need for age‐tailored suicide prevention programs. The present findings might also suggest that health care professionals should consider feelings of loneliness rather than social support to assess the presence of suicide ideation in older people. 相似文献

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. 相似文献
