This prospective cohort study used administrative data from the Army Study to Assess Risk and Resilience in Servicemembers to examine associations between neurocognitive functioning and subsequent suicidal events among Regular Army enlisted soldiers during the years 2004–2009. Cases were all soldiers who completed the Army's Automated Neuropsychological Assessment Metrics (ANAM) computerized testing battery prior to documented suicide attempt (n = 607), ideation (n = 955), or death (n = 57). Controls were an equal‐probability sample of 9,893 person‐months from other soldiers. Exploratory factor analysis of five ANAM tests identified a general neurocognitive factor that excluded the mathematic processing test (MTH). When examined separately in logistic regression analyses that controlled for sociodemographics and prior mental health diagnosis, both the general neurocognitive factor (logit [β] = ?.197 to ?.521; p < .01) and MTH (β = ?.024 to ?.064; p < .05) were associated with all outcomes. When both predictors were examined simultaneously, the general neurocognitive factor continued to be associated with all outcomes (β = ?.164 to ?.417; p < .05) and MTH continued to be associated with suicide attempt (β = ?.015; p = .046) and ideation (β = ?.014; p = .018). These small but robust associations suggest that future research must continue to examine the extent to which objective neurocognitive tests may enhance understanding and prediction of suicide risk. 相似文献

Several ethological reports have indicated that cooperative behaviors play an adaptive role. However, research has focused on competition in men, and there have been few studies on cooperation. This study aims to analyze the cortisol and psychological responses in women to a cooperative situation compared with a competitive situation in a laboratory context. The sample was distributed into four groups depending on the task and the outcome obtained: Positive cooperation, negative cooperation, competition with victory, and competition with defeat. Our results show that, in comparison with competition, cooperation produces different effects in cortisol, but not in psychological states. Nevertheless, these effects occur only when the task outcome and its appraisal are considered. Only the participants who cooperated and obtained a positive outcome and those who competed and lost showed significant decrements of cortisol. Internal attribution was higher in groups with more stable cortisol levels, suggesting a possible modulator effect of controllability in the way the situation was experienced. These results could be generalized to situations in which negotiation, mediation, and cooperative strategies are relevant for making decisions and/or solving problems. 相似文献
