Sleep disturbances are endemic in military personnel with nonclinical populations averaging 6 hours of sleep. The Pittsburgh Sleep Quality Index (PSQI), however, has not been validated in this population. It is thus unknown if the PSQI can differentiate clinically significant sleep disorders from sleep disturbances resulting from military duties with restricted sleep periods. After a clinical evaluation and polysomnogram, participants (N = 148) were classified as having insomnia only, obstructive sleep apnea (OSA) only, comorbid insomnia and OSA (CIO), service-related illnesses only (SRI–; pain, depression, posttraumatic stress disorder, traumatic brain injury), and controls. Military personnel in the insomnia only, and the CIO groups had higher PSQI scores (13.5 ± 2.8 and 14.7 ± 3.5, respectively) compared to the controls (8.9 ± 3.9). A cut-off score of ≥10 was optimal (90% sensitivity and 69% specificity) for determining clinically significant insomnia (≥12 for CIO; 84% sensitivity, 77% specificity). In military personnel, a PSQI score >5 is not necessarily indicative of a clinically significant sleep disorder. The use of elevated cut-off PSQI scores are likely better suited to differentiate military personnel who require further clinical evaluation versus a more conservative sleep improvement protocol. 相似文献

重大军事任务下军人急性应激反应特点 总被引：1，自引：0，他引：1
目的：揭示军人在执行重大军事任务期间急性应激反应特点。方法：采用《急性应激反应量表》对执行重大军事任务下军人的心理反应进行测试和对比。结果：五种重大军事任务下,军人的急性应激反应各维度及总反应指数均存在显著性差异,急性应激反应主要表现在认知改变和情绪变化方面;执行任务过程中的暴露因素影响军人急性应激反应的程度;军人急性应激反应各症状与工作效率降低呈显著正相关,影响工作效率的因素主要为生理反应、焦虑、注意减退和自责。结论：随着执行重大任务的性质和暴露因素不同,军人急性应激反应特点存在显著差异,并对军事作业效能产生明显的影响。 相似文献

The goal of this research is to study the impact of geographical celibacy on work-family conflict and job satisfaction. Indeed, we made the hypotheses that geographical celibates will have more negative feeling toward these two concepts. In order to test these hypothesis, 5298 sailors of the French Navy answered a questionnaire that measured job satisfaction and work-family conflict. Results show that there are differences and that geographical celibates feel more conflict than non-geographical celibates. Moreover, they are less satisfied by their job. This study allows us to question the relevance of this status in a military institution where mobility is particularly high. 相似文献

廖平对《春秋》经的认识,有前后两个阶段的变化。在廖平的经学史研究阶段,认为《春秋》是孔子所制作的“经”,包含了孔子的“素王制作”之义,即为后世的“一王之法”;在其经学理论的建构时期,《春秋》经被廖平作为其建构孔经“人学”的经典。事实上,《春秋经》廖平的孔经天人体系中只不过是一种工具符号,且随着廖平经学理论的变化,被不断地赋予不同的功能。 相似文献

The interpersonal-psychological theory of suicide posits that the interaction of three elements is required for lethal suicidal behaviors: the perception that one is a burden on others, the perception that one does not belong, and fearlessness about death combined with high pain tolerance (termed “acquired capability” for suicide). Although an ever expanding research base supports the theory, very limited data exist supporting the theory among military personnel, a group that has experienced a rapid increase in suicides during the past several years. The current study tests the interpersonal-psychological theory in two clinical samples of military personnel while deployed to Iraq: those seeking treatment for mild traumatic brain injury, and those seeking outpatient mental health treatment. In both samples, perceived burdensomeness and acquired capability were significantly associated with suicidality, as was their interaction term. Results partially support the interpersonal-psychological theory of suicide, and indicate that perceptions of burdensomeness combined with fearlessness about death are associated with increased suicidality among deployed military personnel. 相似文献

To shield a romantic partner from potential distress due to stressors occurring during deployment, service members (SMs) may engage in protective buffering, or withholding information or concerns from a romantic partner. This study utilized data from 54 couples collected before, during, and after a military deployment to assess whether SMs engaged in protective buffering while deployed and the possible associations between buffering and psychological, relationship, and contextual factors. Only 2% of SMs indicated never engaging in protective buffering during a deployment. In bivariate analyses, only partners’ psychological distress prior to deployment was significantly associated (negatively) with protective buffering. In multilevel models with time nested within individuals, and individuals nested within couples, higher buffering was associated with less partner distress during deployment, but was also associated with higher SM distress both during and after deployment. In these multilevel models, protective buffering was not significantly associated with SM or partner marital satisfaction. 相似文献

Little is known about the association of military sexual trauma (MST) and relationship satisfaction among partnered female service members/veterans (SM/Vs). Extant civilian literature shows a strong association between sexual trauma and poorer relationship outcomes, and theory suggests that sexual function and satisfaction may mediate this association. Given that as many as 40% of female SM/Vs report MST and roughly half of female veterans are partnered and in their peak sexual years, it is critical to understand the association of MST, relationship satisfaction, sexual function, and sexual satisfaction in this population. Female SM/Vs (N = 817) completed a demographic inventory, self-report measures of MST, relationship satisfaction, sexual function, and sexual satisfaction. One hundred fifty-one (18.48%) participants did not experience MST. Three hundred eighty-eight (47.49%) reported that they experienced harassment-only MST, and 278 (34.03%) reported assault MST. At the bivariate level, lower relationship satisfaction was associated with lower sexual function and satisfaction with large effect sizes. Assault MST was associated with lower relationship satisfaction and sexual function and satisfaction with small-to-medium effect sizes. No differences in relationship satisfaction, sexual satisfaction, and function between those with harassment-only and no MST were observed. Mediation analyses demonstrated that lower sexual function and satisfaction mediated the association of assault MST and relationship satisfaction. Couples’ therapy offered to SM/Vs with MST should screen for type of MST, sexual function, and satisfaction. Addressing the sequelae of MST and increasing sexual function and satisfaction in these partnerships may be critical treatment targets. 相似文献
