The association between current level of suicidal ideation and physical activity was tested in a broad sample of veterans seeking care from the Veterans Health Administration. It was hypothesized that the two variables would be significantly inversely related. It was further hypothesized that the relationship would be mediated by depressive symptoms, disturbed sleep, and a measure of heart rate variability based on existing research regarding physical activity and sleep. Due to the first hypothesis not being supported, the second could not be tested. Post hoc correlation analyses did find associations between physical activity and depressive symptoms, in expected directions, and are discussed. Possible explanations for the negative findings along with recommendations for future research to continue exploring links between suicide risk and physical activity are presented. We conclude by suggesting that physical activity may have promise as a risk reduction intervention and that prospective data are more likely to yield significant results than the cross‐sectional methodology employed in the current study. 相似文献

To better delineate the unique correlates of self‐injurious behaviors (SIB), psychiatric profiles of mutually exclusive groups of adolescents who made a suicide attempt (SA) versus those engaged in nonsuicidal self‐injury (NSSI) were examined. Contrary to hypotheses, the NSSI group endorsed earlier onsets of SIB and suicidal ideation (SI), as well as higher rates of depression and anxiety compared with their SA counterparts. Future work is warranted to understand the role of SI, including duration of SI and anxiety in the development of NSSI, and to identify risk and resiliency factors useful in predicting an adolescent's SIB status. 相似文献

Previous research in US Army Soldiers shows rates of mental health concerns as two to four times higher on anonymous surveys than on postdeployment health assessments. In this study, Soldiers presenting for health reassessment completed two questionnaires on suicide risk factors: one linked to the health assessment and one anonymous. About 5.1% of respondents reported suicide ideation on the anonymous questionnaire, 3.0% on the linked questionnaire, and 0.9% on the health reassessment. About 56.4% who reported suicide ideation anonymously told nobody of their thoughts. Current screening procedures identify only one in seven Soldiers experiencing suicide ideation and highlight the need for alternative risk‐detection strategies. 相似文献

The experience of the most distressing patient suicide on Flemish psychiatrists is described. Of 584 psychiatrists, 107 filled a self‐report questionnaire. Ninety‐eight psychiatrists had been confronted with at least one patient suicide. Emotional suffering and impotence were the most common feelings reported. Changes in professional practice were described and included a more structured approach to the management of suicidal patients. Colleagues and contact with the patient's family were the most frequently used sources of help, whereas team case review and colleagues were rated as the most useful ones. Patient suicide leads to emotional suffering and has a considerable professional impact. 相似文献

A systematic search was performed to identify active, externally funded randomized controlled trials (RCTs) that target suicidal ideation or behavior as a primary or secondary outcome among U.S. military service members, guard–reservists, and veterans. Twenty‐three studies were identified, most funded by the U.S. Department of Defense or U.S. Department of Veterans Affairs. Several innovations were identified based on departures from or modernizations of usual practices and included the targeting of suicide deaths or attempts as primary outcome, delivery of interventions through technology and/or outside clinical settings, and examinations of rarely studied treatments. 相似文献
