Military personnel and veterans have important suicide risk factors. After a systematic review of the literature on suicide prevention, seven (five in the U.S.) studies of military personnel were identified containing interventions that may reduce the risk of suicide. The effectiveness of the individual components was not assessed, and problems in methodology or reporting of data were common. Overall, multifaceted interventions for active duty military personnel are supported by consistent evidence, although of very mixed quality, and in some cases during intervals of declines in suicide rates in the general population. There were insufficient studies of U.S. Veterans to reach conclusions. 相似文献

Death by suicide demonstrates profound personal suffering and societal failure. While basic sciences provide the opportunity to understand biological markers related to suicide, computer science provides opportunities to understand suicide thought markers. In this novel prospective, multimodal, multicenter, mixed demographic study, we used machine learning to measure and fuse two classes of suicidal thought markers: verbal and nonverbal. Machine learning algorithms were used with the subjects’ words and vocal characteristics to classify 379 subjects recruited from two academic medical centers and a rural community hospital into one of three groups: suicidal, mentally ill but not suicidal, or controls. By combining linguistic and acoustic characteristics, subjects could be classified into one of the three groups with up to 85% accuracy. The results provide insight into how advanced technology can be used for suicide assessment and prevention. 相似文献

Positive psychology has garnered considerable scholarly interest recently and has been suggested to hold promise in the application to suicide research and prevention; however, empirical research has lagged behind these suggestions. This is the first study to examine the relationship between hope and a specific theory of suicide in African Americans. It was hypothesized that (1) hope would negatively predict the interpersonal suicide risk factors of burdensomeness and thwarted belongingness; and positively predict acquired capability to enact suicide; (2) hope would negatively predict suicidal ideation; and (3) the interpersonal suicide risk factors would predict suicidal ideation. Results were primarily as predicted. Implications for hope theory and Joiner's theory of suicidal behavior are discussed, as well as implications for clinical practice. 相似文献

While we endorse recent calls for greater collaboration between mass communication and interpersonal communication researchers, in this response we delineate four factors that account for the relative lack of integration of these two areas of communication inquiry. The social policy focus of mass communication research, the high level of public concern over media effects, a variety of methodological cleavages, and different cognate field referents are cited as forces that support segregation of the two research areas. The recent turn to cognitive explanations of communication in both of these domains may create the climate necessary for meaningful collaboration between researchers. 相似文献

Research investigating suicide attempts and deaths by suicide has yielded many specific risk factors and warning signs for future suicidal behaviors. Yet, even though these variables are each valuable for suicide prevention efforts, they may be limited in their applicability to clinical practice. The differences among risk factors, warning signs, and “drivers,” which are person‐specific variables that lead individuals to desire death by suicide, are highlighted. The scarce evidence on drivers is described and specific recommendations for conducting future drivers‐focused research and targeting them in clinical practice are suggested. 相似文献
