The absence of validated U.S. rates of nonfatal suicidal behavior places risk management and injury prevention programs at danger of being poorly informed and inadequately conceptualized. In this study we compare estimated rates of intentional self-harm from two ongoing surveys (National Electronic Injury Surveillance System-All Injury Program-NEISS-AIP; National Hospital Ambulatory Medical Care Survey-NHAMCS) to data from the Toxic Exposure Surveillance System. Results suggest that, for every 2002-2003 suicide, there were 12 (NEISSAIP) or 15 (NHAMCS) self-harm-related emergency department visits, and for every intentional self-poisoning death there were 33 intentional overdoses reported to poison control centers, of which two ultimately went untreated. 相似文献

Prior research on age and emotions has found that older adults may show better physiological regulation to stressful stimuli than do younger adults. However, the stress reactivity literature has shown that age is associated with higher cardiovascular reactivity to laboratory stress (J. R. Jennings et al., 1997). The authors investigated these conflicting findings further by examining daily ambulatory blood pressure in 428 middle-aged to older adults. Consistent with the age and reactivity literature, relatively old individuals showed significantly greater increases in ambulatory diastolic blood pressure compared with younger individuals when dealing with daily stressors. However, results also revealed that relatively old individuals reported less of an increase in negative affect during daily stress compared with their younger counterparts. The results of this study are consistent with the age-related increase in cardiovascular risk but highlight the complex links between stress and different facets of the aging process. 相似文献

In this study, a follow-up to Callanan and Perri (2006), the authors investigated whether individuals are inclined to choose a conflict-handling approach based on their primary orientation as given by a standardized instrument, or whether they choose a style different from their primary orientation. The authors also assessed whether individuals are inclined to choose the appropriate or "optimal" strategy as based on contextual factors embodied in the conflict situation. Participants in the study were 184 graduate and undergraduate students from two universities located in the United States. Results show that when individuals are presented with conflict scenarios based on real-life events, they can and do choose conflict-handling strategies that are different from their presumed dominant strategy. Further, results show that individuals are generally able to read contextual factors and social cues to select the most "situationally appropriate" conflict-handling response. This study presents implications for future research and discusses issues related to the management of interpersonal and intragroup conflict. 相似文献

Semantic priming refers to a reduction in the reaction time to identify or make a judgment about a stimulus that has been immediately preceded by a semantically related word or picture and is thought to result from a partial overlap in the semantic associates of the two words. A semantic priming lexical decision task using spoken words was presented in event-related fMRI and behavioral paradigms. Word pairs varied in terms of semantic relatedness and the connectivity between associates. Thirteen right-handed subjects underwent fMRI imaging and 10 additional subjects were tested in a behavioral version of the semantic priming task. It was hypothesized priming would be greatest, reaction time fastest, and cortical activation reduced the most for related word pairs of high connectivity, followed by related word pairs of low connectivity, and then by unrelated word pairs. Behavioral and fMRI results confirmed these predictions. fMRI activity located primarily in bilateral posterior superior and middle temporal regions showed modulation by connectivity and relatedness. The results suggest that these regions are involved in semantic processing. 相似文献

In contrast to the view that social perception has symmetric effects on judgments and behavior, the current research explored whether perspective-taking leads stereotypes to differentially affect judgments and behavior. Across three studies, perspective-takers consistently used stereotypes more in their own behavior while simultaneously using them less in their judgments of others. After writing about an African-American, perspective-taking tendencies were positively correlated with aggressive behavior but negatively correlated with judging others as aggressive. Similarly, after writing about an elderly man, perspective-takers walked more slowly and became more conservative, but judged others as less dependent. These divergent effects of perspective-taking on judgment and behavior occurred regardless of whether perspective-taking was manipulated or measured, whether judgments were measured before or after behavior, the stereotype that was activated, and participants’ culture (American, Singaporean). These findings support theorizing that judgments and behavior can diverge when individuals’ social strategies are geared towards establishing and maintaining social bonds, as well as provide insight into how perspective-taking helps individuals manage diversity. 相似文献

224 suicides from the Golden Gate Bridge in 1999-2009 were younger than other suicides handled by the Marin County Coroner but did not differ by sex or race. Those witnessed did not differ from those not witnessed. Compared to suicides from the bridge in the 1970s, recent suicides were older, more often male, and more often nonwhite. 相似文献

Reference checking is a near‐universal practice within personnel selection systems, and legal pressures to gather job‐relevant and structured feedback from references is mounting. Despite this state of affairs, reference checking is a woefully under‐researched method for obtaining psychometrically sound and behaviorally informative data that predict task, team, and leadership behavior at work. From studies of job candidates in applied settings, this article reports on the reliability, validity, and compliance of multisource reference feedback gathered using a web‐based methodology. Acceptable levels of internal consistency, inter‐rater reliability, and test–retest reliability of the reference‐checking instrument were realized. Results of survival analyses found support for prediction of involuntary, but not voluntary turnover. No practically significant differences were found in overall mean scores across demographic subgroups. Finally, the web‐based reference‐checking system evinced high degrees of efficiencies across a range of metrics (e.g., reference response time, reference response rate, candidate response time). 相似文献

This study examines the use of a modified form of the theory of planned behavior in understanding the decisions of undergraduate students in engineering and humanities to engage in cheating. We surveyed 527 randomly selected students from three academic institutions. Results supported the use of the model in predicting ethical decision-making regarding cheating. In particular, the model demonstrated how certain variables (gender, discipline, high school cheating, education level, international student status, participation in Greek organizations or other clubs) and moral constructs related to intention to cheat, attitudes toward cheating, perceptions of norms with respect to cheating, and ultimately cheating behaviors. Further the relative importance of the theory of planned behavior constructs was consistent regardless of context, whereas the contributions of variables included in the study that were outside the theory varied by context. Of particular note were findings suggesting that the extent of cheating in high school was a strong predictor of cheating in college and that engineering students reported cheating more frequently than students in the humanities, even when controlling for the number of opportunities to do so. 相似文献

Multi-tiered systems of social behavioral support in schools provide varying levels of intervention matched to student need. Tier I (primary or universal) systems are for all students and are designed to promote pro-social behavior. Tier III (tertiary or intensive) supports are for students who engage in serious challenging behavior that has not responded to other efforts. In between Tier I and Tier III are Tier II (secondary or targeted interventions), for students at risk for developing more serious problematic behavior. The purpose of this study was to evaluate Breaks are Better, a Tier II intervention designed for students who engage in problem behavior maintained by avoidance of instructional activities. Breaks are Better builds on an evidence-based Tier II intervention, Check-in/Check-out, but includes key components to enhance its effectiveness for students who avoid instruction. Working with three typically developing elementary school students, we documented changes in problem behavior during academic instruction following the implementation of Breaks are Better. Further, students and teachers rated the intervention as both feasible and valuable. 相似文献

Thirty left-handed and right-handed Ss (10 each from the second grade, fifth grade, and college) were compared on four subtests of the Torrance creativity test. At each age level, left-handed students had higher creativity scores than right-handers. The greatest differences were found on the Elaboration subtest. 相似文献
