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

Many models of the processing of printed or spoken words or objects or faces propose that systems of local representations of the forms of such stimuli—lexicons—exist. This is denied by partisans of the distributed-representation connectionist approach to cognitive modelling. An experimental paradigm of key theoretical importance here is lexical decision and its analogue in the domain of objects, object decision. How does each theoretical camp account for our ability to perform these two tasks? The localists say that the tasks are done by matching or failing to match a stimulus to a local representation in a lexicon. Advocates of distributed representations often do not seek to explain these two tasks; however, when they do, they propose that patterns of activation evoked in a semantic system can be used to discriminate between words and nonwords, or between real objects and false objects. Therefore the distributed-representation account of lexical and object decision tasks predicts that performance on these tasks can never be normal in patients with an impaired semantic system, nor in patients who cannot access semantics normally from the stimulus domain being tested. However, numerous such patients have been reported in the literature, indicating that semantic access is not needed for normal performance on these tasks. Such results support the localist form of modelling rather than the distributed-representation approach. 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

Although the significance of poor physical health for suicide risk is well established, the potential relevance of physical disability, as distinct from diseases and traumas that give rise to disability, has received little attention. Prior evidence suggests the possible utility of the stress process theoretical model for understanding variations in risk for suicide ideation and the contribution of physical disability to such risk. In this article, we examine the independent and joint explanatory significance of physical disability and components of the stress process model for risk of suicide ideation. Data from an ethnically diverse and representative sample of disabled and nondisabled adults (n = 1,768) reveal that physical disability is associated with a greater risk of lifetime suicidal ideation. 相似文献

This paper describes a preliminary study examining the relative power of measures of perceived family support, hopelessness, and depression for the classification of suicide attempters and nonattempters in a series of 8- to 13-year-old psychiatric inpatients. Results of a stepwise discriminant-function analysis indicated that a measure of a child's perceived family support discriminated between suicide attempters and nonattempters with an 88% accuracy rate. The addition of measures of hopelessness and depression at later steps did not lead to improved classification. The results are interpreted as providing strong support for a link between suicide attempts in children and perceptions of low family support. 相似文献

The “Viennese Instrument for Suicidality in Correctional Institutions” (VISCI) presented here is based on the results of a large case‐control study and on research on literature examining suicide prevention in general and in the prison population in particular. The aim of this study was to validate the properties of the VISCI to differentiate between suicides and nonsuicides. The sensitivity and specificity of the VISCI was tested in the files of 55 correctional suicides, and 110 controls. VISCI differentiated well between suicides and nonsuicides. The routine administration of the VISCI may help to direct the existing professional attention to inmates with the highest need. 相似文献

The prevalence and persistence of thoughts of death and suicide during early adolescence were estimated in a community‐based cohort. A latent class approach was used to identify distinct subgroups based on endorsements to depression items administered repeatedly over 24 months. Two classes emerged, with 75% in a low ideation class across four assessments. Less than 2% persisted in the high ideation class over three or more assessments. African American and Asian American adolescents were more likely than European Americans to belong to the high ideation class. No members of the low ideation class endorsed “thought about killing myself,” while “thoughts of death and dying” was endorsed by members of both classes. Implications for interpreting meanings of death and suicide ideation in early adolescence are discussed. 相似文献
