Hopelessness is one of the most commonly cited risk factors for suicidal behaviors. However, several retrospective studies suggest that hopelessness, while strongly correlated with suicide ideation, does not distinguish attempters from ideators without attempts. This study is the first to utilize a prospective design to disambiguate the relationship of hopelessness to ideation versus attempts. Participants were 142 depressed patients followed up over 10 years. Hopelessness and suicidality (ideation and attempts) were assessed using validated questionnaires and structured interviews. Both retrospective and prospective analyses revealed that hopelessness was higher among those reporting any suicidality (ideation or attempts) compared with nonsuicidal individuals. However, hopelessness failed to meaningfully distinguish attempters from ideators in both retrospective and prospective analyses. Taken together with results from previous studies, our findings suggest hopelessness is best conceptualized as a risk factor for suicide ideation but not progression from ideation to attempts. 相似文献

Synapsin is an evolutionarily conserved, presynaptic vesicular phosphoprotein. Here, we ask where and how synapsin functions in associative behavioral plasticity. Upon loss or reduction of synapsin in a deletion mutant or via RNAi, respectively, Drosophila larvae are impaired in odor-sugar associative learning. Acute global expression of synapsin and local expression in only the mushroom body, a third-order "cortical" brain region, fully restores associative ability in the mutant. No rescue is found by synapsin expression in mushroom body input neurons or by expression excluding the mushroom bodies. On the molecular level, we find that a transgenically expressed synapsin with dysfunctional PKA-consensus sites cannot rescue the defect of the mutant in associative function, thus assigning synapsin as a behaviorally relevant effector of the AC-cAMP-PKA cascade. We therefore suggest that synapsin acts in associative memory trace formation in the mushroom bodies, as a downstream element of AC-cAMP-PKA signaling. These analyses provide a comprehensive chain of explanation from the molecular level to an associative behavioral change. 相似文献

The present study explored attitudes toward feminism in 245 U.S. college students and their older relatives. Participants completed a scale of attitudes towards feminism, political orientation, a religiosity measure, and a demographic questionnaire. Results indicated that older adults were more conservative than younger adults on their attitudes towards feminism, religiosity, and political orientation measures. In the young adult sample, attitudes towards feminism were predicted by gender and political orientation, compared to older adults in which religiosity and political orientation were the best predictors. When exploring generational influence, older adults?? attitudes and demographic information were not associated with younger adults?? attitudes towards feminism and the women??s movement. In contrast, young adults?? political views were associated with older adults?? attitudes towards feminism. 相似文献

Using a longitudinal sample of MBA graduates, the present study investigates why employees who are high in positive affect (PA) sometimes display higher rates of turnover, as well as the consequences of frequent turnover for long‐term satisfaction. Results show that high PA employees had higher salary expectations than other employees, and that the relationship between low salary and frequent turnover in the 4 years following graduation was stronger among employees higher in PA. High PA employees who changed organizations more frequently in the first 4 years following graduation reported lower job satisfaction and lower life satisfaction 8 years into their careers, a trend that was reversed for low PA employees. 相似文献

This paper explores the ethical and conceptual implications of the findings from an empirical study of decision-making capacity in anorexia nervosa. In the study, ten female patients aged 13 to 21 years with a diagnosis of anorexia nervosa, and eight sets of parents, took part in semi-structured interviews. The purpose of the interviews was to identify aspects of thinking that might be relevant to the issue of competence to refuse treatment. All the patient participants were also tested using the MacCAT-T test of competence. This is a formalised, structured interviewer-administered test of competence, which is a widely accepted clinical tool for determining capacity. The young women also completed five brief self-administered questionnaires to assess their levels of psychopathology.The issues identified from the interviews are described under two headings: difficulties with thought processing, and changes in values. The results suggest that competence to refuse treatment may be compromised in people with anorexia nervosa in ways that are not captured by traditional legal approaches or current standardised tests of competence. 相似文献

Emergency Department Youth Patients With Suicidal Ideation or Attempts: Predicting Suicide Attempts Through 18 Months of Follow‐Up 下载免费PDF全文
Joan Rosenbaum Asarnow PhD Michele Berk PhD Lily Zhang MS Peter Wang BA Lingqi Tang PhD 《Suicide & life-threatening behavior》2017,47(5):551-566
This prospective study of suicidal emergency department (ED) patients (ages 10–18) examined the timing, cumulative probability, and predictors of suicide attempts through 18 months of follow‐up. The cumulative probability of attempts was as follows: .15 at 6 months, .22 at 1 year, and .24 by 18 months. One attempt was fatal, yielding a death rate of .006. Significant predictors of suicide attempt risk included a suicide attempt at ED presentation (vs. suicidal ideation only), nonsuicidal self‐injurious behavior, and low levels of delinquent symptoms. Results underscore the importance of both prior suicide attempts and nonsuicidal self‐harm as risk indicators for future and potentially lethal suicide attempts. 相似文献

Two experiments were conducted to evaluate the ability of younger and older adults to recognize 3-D object shape from patterns of optical motion. In Experiment 1, participants were required to identify dotted surfaces that rotated in depth (i.e., surface structure portrayed using the kinetic depth effect). The task difficulty was manipulated by limiting the surface point lifetimes within the stimulus apparent motion sequences. In Experiment 2, the participants identified solid, naturally shaped objects (replicas of bell peppers, Capsicum annuum) that were defined by occlusion boundary contours, patterns of specular highlights, or combined optical patterns containing both boundary contours and specular highlights. Significant and adverse effects of increased age were found in both experiments. Despite the fact that previous research has found that increases in age do not reduce solid shape discrimination, our current results indicated that the same conclusion does not hold for shape identification. We demonstrated that aging results in a reduction in the ability to visually recognize 3-D shape independent of how the 3-D structure is defined (motions of isolated points, deformations of smooth optical fields containing specular highlights, etc.). 相似文献
