Oregon Violent Death Reporting System data were linked with Veterans Affairs (VA) administrative data to identify and describe veterans who completed suicide in Oregon from 2000 to 2005 (n = 968), and to describe their VA health care utilization in the year prior to death. Twenty-two percent had received health care in the VA system. Of these, 57% did not have mental health diagnoses and 58% had not seen mental health professionals. A larger proportion of those who accessed care were VA-enrolled and received service-connected disability benefits. Fifty-five veterans were hospitalized during the year prior to death. Of these, 33% completed suicide within 30 days of a hospitalization. Further development of suicide prevention strategies for veterans in the community, including general medical treatment settings, is indicated.  相似文献

The Elemental Psychopathy Assessment (EPA) is a new self-report measure of psychopathy designed to assess the personality traits associated with psychopathy from a Five Factor Model perspective. The current study examined the validity of the EPA in sample of undergraduates by examining the relations between the EPA scales and three validated self-report psychopathy instruments, as well as assessments of aggression, substance use, and antisocial behavior. The EPA scales manifested strong convergent validity with the extant psychopathy measures and an expected pattern of relations with measures of externalizing behaviors. Overall, the EPA appears to be a promising measure of psychopathy which provides new opportunities to explore the underlying structure of this construct and parse its relations with constructs central to its nomological network.  相似文献

Variations in the serotonin transporter gene (5HTTLPR) and biased processing of face-emotion displays both have been implicated in the transmission of depression risk, but little is known about developmental influences on these relationships. Within a community sample of adolescents, we examine whether 5HTTLPR genotype moderates the link between maternal depressive history and errors in face-emotion labeling. When controlling for current levels of depression and anxiety among youth, a two-way interaction between maternal depressive history and 5HTTLPR genotype was detected. Specifically, adolescents whose mothers reported a depressive history and who had a low expressing genotype made more errors in classifying emotional faces when compared with adolescents with an intermediate or high expressing genotype, with or without maternal depression history. These findings highlight the complex manner in which maternal depression and genetic risk may interact to predict individual differences in social information processing.  相似文献

This study uses intraindividual variability and change methods to test theoretical accounts of self-concept and its change across time and context and to test the developmental implications of this variability. The 5-year longitudinal study of 541 youths in a rural Pennsylvania community from 3rd through 7th grade included twice-yearly assessments of self-concept (academic and social), corresponding external evaluations of competence (e.g., teacher-rated academic skills, peer-nominated "likeability"), and multiple measures of youths' overall adjustment. Multiphase growth models replicate previous research, suggesting significant decline in academic self-concept during middle school but modest growth in social self-concept from 3rd through 7th grade. Next, a new contribution is made to the literature by quantifying the amount of within-subject variability (i.e., "lability") around these linear self-concept trajectories as a between-subjects characteristic. Self-concept lability was found to associate with a general profile of poorer competence and adjustment and to predict poorer academic and social competence at the end of 7th grade above and beyond level of self-concept. Finally, there was substantial evidence that wave-to-wave changes in youths' self-concepts correspond to teacher and peer evaluations of youths' competence, that attention to peer feedback may be particularly strong during middle school, and that these relations may be moderated by between-subjects indicators of youths' general adjustment. Overall, findings highlight the utility of methods sensitive to within-subject variation for clarifying the dynamics of youths' self-system development.  相似文献

The present study examined the relationship between hand preference degree and direction, functional language lateralization in Broca’s and Wernicke’s areas, and structural measures of the arcuate fasciculus. Results revealed an effect of degree of hand preference on arcuate fasciculus structure, such that consistently-handed individuals, regardless of the direction of hand preference, demonstrated the most asymmetric arcuate fasciculus, with larger left versus right arcuate, as measured by DTI. Functional language lateralization in Wernicke’s area, measured via fMRI, was related to arcuate fasciculus volume in consistent-left-handers only, and only in people who were not right hemisphere lateralized for language; given the small sample size for this finding, future investigation is warranted. Results suggest handedness degree may be an important variable to investigate in the context of neuroanatomical asymmetries.  相似文献

Body dissatisfaction in women in the United States is common. We explored how women from various racial and ethnic groups used figural stimuli by exploring differences in current and preferred silhouette, and their discrepancy. We surveyed 4023 women aged 25–45 in an online investigation. Participants were identified using a national quota-sampling procedure. Asian women chose a smaller silhouette to represent their current body size, which did not remain significant after adjusting for self-reported BMI. After controlling for BMI, African American women selected a smaller silhouette than White women to represent their current size. Both African American and women reporting “Other” race preferred larger silhouettes than White women even after controlling for BMI. The discrepancy score revealed lower body dissatisfaction among African American than White women. Understanding factors that promote body satisfaction differentially across racial and ethnic groups could become a tool in appropriately tailored interventions designed to prevent eating disorders.  相似文献

Executive attention and self-regulation in infancy   总被引:1,自引:0,他引:1  
This study investigates early executive attention in infancy by studying the relations between infant sequential looking and other behaviors predictive of later self-regulation. One early marker of executive attention development is anticipatory looking, the act of looking to the location of a target prior to its appearance in that location, a process that involves endogenous control of visual orienting. Previous studies have shown that anticipatory looking is positively related to executive attention as assessed by the ability to resolve spatial conflict in 3–4-year-old children. In the current study, anticipatory looking was positively related to cautious behavioral approach in response to non-threatening novel objects in 6- and 7-month-old infants. This finding and previous findings showing the presence of error detection in infancy are consistent with the hypothesis that there is some degree of executive attention in the first year of life. Anticipatory looking was also related to the frequency of distress, to looking away from disturbing stimuli, and to some self-regulatory behaviors. These results may indicate either early attentional regulation of emotion or close relations between early developing fear and later self-regulation. Overall, the results suggest the presence of rudimentary systems of executive attention in infants and support further studies using anticipatory looking as a measure of individual differences in attention in infancy.  相似文献

The prediction of events and the creation of expectancies about their time course is a crucial aspect of an infant's mental life, but temporal mechanisms underlying these predictions are obscure. Scalar timing, in which the ratio of mean durations to their standard deviations is held constant, enables a person to use an estimate of the mean for its standard deviation. It is one efficient mechanism that may facilitate predictability and the creation of expectancies in mother-infant interaction. We illustrate this mechanism with the dyadic gaze rhythm of mother and infant looking at and looking away from each other's faces. Two groups of Hi- and Lo-Distress mothers were created using self-reported depression, anxiety, self-criticism and childhood experiences. Lo-Distress infants (controls) used scalar timing 100% of the time, about double that of Hi-Distress infants. Lo-Distress mothers used scalar timing about nine times as much as Hi-Distress mothers. The diminished use of scalar timing patterns in Hi-Distress mothers and infants may make the anticipation of each other's gaze patterns more difficult for both partners.  相似文献

Skepticism regarding the importance of personality traits as predictors of organizational behavior criteria has given way to an appreciation of the broad array of work outcomes predicted by personality. This article considers the effects of the five‐factor model (‘Big Five’) personality traits on the following work outcomes: (1) job performance; (2) work motivation; (3) job attitudes; (4) leadership; (5) power, politics, and influence; (6) stress, adaptability, and coping; (7) team effectiveness; (8) counterproductive/deviant workplace behaviors; (9) workplace accidents; and (10) conflict and negotiation. Two contemporary criticisms of personality research in organizational behavior – that the validities are small and that faking undermines the usefulness of personality inventories in employment contexts – are then evaluated. Finally, a brief agenda for future research is provided which highlights needed areas of advancement.  相似文献
