This qualitative study examined sexual health information networks among urban African American youth living in low-income communities. The authors identified sources, message content, and utility of messages about sex and sexual health in a sample of 15-17-year olds (N = 81). Youth received sexual health information from a variety of sources. Messages from parents and sex education had high utility, whereas messages from the Internet and religion had low utility. Four information network patterns were identified, suggesting considerable variation in how youth are socialized regarding sex. Findings suggest that sexual information networks have the potential to affect sexual health and development. 相似文献

Sexual debut represents a developmental transition that holds possibility for growth and for risk. Family and neighborhood may impact timing of debut. This qualitative study examined family strategies (e.g., moving, parental monitoring), perceptions of neighborhood, and attitudes about sex and sexual debut among sexually experienced and inexperienced African American adolescent females living in disadvantaged urban neighborhoods. Findings show that more familial strategies were reported by sexually inexperienced females, suggesting that strategies may delay sexual debut. Furthermore, experiences with neighborhood violence related to attitudes about sex and sexual debut, suggesting a linkage between death anxiety and sexual debut among female youth. 相似文献

In face of the multiple controversies surrounding the DSM process in general and the development of DSM-5 in particular, we have organized a discussion around what we consider six essential questions in further work on the DSM. The six questions involve: 1) the nature of a mental disorder; 2) the definition of mental disorder; 3) the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4) the role of pragmatic considerations in the construction of DSM-5; 5) the issue of utility of the DSM - whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6) the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system. Part I of this article will take up the first two questions. With the first question, invited commentators express a range of opinion regarding the nature of psychiatric disorders, loosely divided into a realist position that the diagnostic categories represent real diseases that we can accurately name and know with our perceptual abilities, a middle, nominalist position that psychiatric disorders do exist in the real world but that our diagnostic categories are constructs that may or may not accurately represent the disorders out there, and finally a purely constructivist position that the diagnostic categories are simply constructs with no evidence of psychiatric disorders in the real world. The second question again offers a range of opinion as to how we should define a mental or psychiatric disorder, including the possibility that we should not try to formulate a definition. The general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances. 相似文献

This paper reexamines the Shuman seminal paper arguing against empathic behaviors in forensic evaluations. Shuman concluded that empathy by examiners seduces evaluees into believing a therapeutic relationship exists. We reconsider empathy as an element of rapport and a helpful supplement in a successful assessment. Actively avoiding empathy could lead to cold and callous examiner self‐presentation, which may in turn produce biased and negative results. In this paper we assert that ethical forensic professionals may use moderate empathy during an assessment. Examiners should consider it not as a component of subjectivity and pseudotherapy, but rather as a potentially useful tool for effective assessments. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

Solid product knowledge and an absolute love for selling have propelled Lee A. Iacocca into the business-world spotlight. Although detractors may criticize some of his corporate management skills, and he personally admits to his share of mistakes (Ingrassia & Stertz 1990), few can doubt the selling and sales management skills of Iacocca. Although much has been written about Iacocca, this article will focus on his specific contributions to the sales discipline. 相似文献

We examined the effect of asking unanticipated interview questions on lie detection. We set up a room in which truth tellers (N = 40) performed five tasks. Liars (N = 40) observed the activity room through a window and were asked to generate a story in which they claim to have performed five tasks. The interview schedule included four thematically related pairs of questions. The first question of each pairing was easy for interviewees to anticipate, as it reflected how events are typically recalled. However, the second included a perspective shift (temporal or spatial), which made the question harder to anticipate. We also measured cognitive load via performance on an object sorting secondary task that interviewees undertook during interview. Compared with truth tellers, liars' verbal responses showed a greater decline in details across three out of four question pairs. Liars also sorted significantly fewer objects per minute on the secondary task. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

The effect of commitment to a learning goal, self-efficacy, and the interaction between learning goal difficulty and goal commitment with performance was investigated using a highly complex business simulation. Participants (n?=?128) needed to acquire knowledge in order to perform the task effectively. The correlation between commitment to the learning goal and performance was positive and significant (r = .47, p < .001). Commitment was also a moderator of the learning goal–task performance effect. The relationship between self-efficacy and performance was partially mediated by commitment to the learning goal. Performance was a partial mediator of the relationship between goal commitment and self-efficacy. Seventy-five percent of the participants self-set a performance goal. The correlation between self-set performance goals and performance was positive and significant (r = .31, p < .001). 相似文献

Applying Cognitive Appraisal Theory (Lazarus &; Folkman, 1984), this study sought to determine the mediating effect of cognitive appraisal on combat exposure and psychological distress. A total of 3,002 military personnel completed measures of combat exposure, cognitive appraisal of combat-related events, and psychological distress either during or soon after combat operations in Afghanistan. Bootstrapping was employed to test the mediation model. Cognitive appraisal mediated the relationship between combat exposure and psychological distress, suggesting that the impact of a potentially stressful event on well-being is contingent on one's appraisal of that event. Implications for future research and training are presented. 相似文献

Antecedents to trust (propensity to trust, perceived trustworthiness) and trust behaviors were examined in relation to team performance in a complex eight-mission military peacekeeping simulation. Teams were colocated or distributed and stayed in the same or transferred to a different context at task transfer. In Experiment 1, an ability and competence factor accounted for most of the variance in perceived trustworthiness and greater perceptions of teammates' abilities/competences predicted posttransfer performance. One's perception of how others perceived one's ability/competence increased over missions. In Experiment 2, propensity to trust did not predict performance; however, trust in others' and one's own ability/competence and trust behaviors predicted performance. At task and/or context transfer, teams produced more monitoring and less cooperating language in their communication. 相似文献
