The high rates of suicide among older men are cause for concern, and have prompted the investigation of factors that might explain these elevated rates. The current research examined whether the gender role construct agency was associated with depression and suicidal ideation among older adults. The results, based on self‐report data from a sample of older Australian men (n = 69) and women (n = 90), indicated that depression mediated the relation between agency and suicidal ideation. In addition, for older men only, agency moderated the depression‐suicidal ideation relation. The results suggest that older adults, and particularly men, with low levels of agency should be the targets for interventions aimed at increasing levels of agency and improving mental health.  相似文献

Epigenetic testing is one of the most significant new technologies to provide insight into the behavioral and environmental factors that influence the development and reconfiguration of the human genetic code. This technology allows us to identify structural changes in the genome that occur due to exposure to a wide variety of substances including alcohol, tobacco, and cannabis. The information gained can be used to promote health but it also raises a variety of ethical, legal, and social issues. As society progresses in understanding the epigenetic mechanisms of substance use and addiction, there is an opportunity to use these use this knowledge to enable medical, behavioral, and environmental interventions to alleviate the burden of addiction. This article describes the ethical issues associated with use of epigenetic testing for alcohol, tobacco, and cannabis and the implications of this technology. A further review of the scientific basis for the relevance of epigenetics is found in the accompanying article by Philibert and Erwin in this issue. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

The relationships among adult attachment styles, interpersonal problems, and categories of suicide‐related behaviors (i.e., self‐harm, suicide attempts, and their co‐occurrence) were examined in a predominantly psychiatric sample (N = 406). Both anxious and avoidant attachment styles were associated with interpersonal problems. In turn, specific interpersonal problems differentially mediated the relations between attachment style and type of suicide‐related behaviors. These findings suggest the importance of distinguishing between these groups of behaviors in terms of etiological pathways, maintenance processes, and treatment interventions.  相似文献

This study used the interpersonal–psychological theory of suicide to explore the relationships among DSM-5 posttraumatic stress disorder (PTSD) symptom clusters derived from the six-factor anhedonia model and facets of acquired capability for suicide (ACS). In a sample of 373 trauma-exposed undergraduates, most PTSD symptom clusters were negatively associated with facets of ACS in bivariate correlations, but the anhedonia cluster was positively associated with ACS in regression models. Structure coefficients and commonality analysis indicated that anhedonia served as a suppressor variable for the other symptom clusters. Our findings further elucidate the complex relationship between specific PTSD symptom clusters and ACS.  相似文献

Remarkably little systematic research has studied the effects of clinical suicidology training on changing practitioner attitudes and behaviors. In the current study we investigated whether training in an empirically‐based assessment and treatment approach to suicidal patients administered through a continuing education workshop could meaningfully impact professional practices, clinic policy, clinician confidence, and beliefs posttraining and 6 months later. At the 6 month follow‐up we found that 44% of practitioners reported increased confidence in assessing suicide risk, 54% reported increased confidence in managing suicidal patients, 83% reported changing suicide care practices, and 66% reported changing clinic policy. These results suggest that a brief and carefully developed workshop training experience can potentially change provider perceptions and behaviors with a possible impact on clinical care therein.  相似文献
