There is evidence that personal experience with trauma is associated with increases in both personal and comparative risk perception. This study investigates this relation in terms of sexual victimization among women, focusing on three potential mediators: perceived control over sexual assault, perceived similarity to a typical sexual assault victim, and psychological distress. Mediational analyses were investigated using structural equation modeling. Although victimization experience was not related to comparative risk perception, it was associated with greater personal risk perception. This relation was mediated by perceived similarity to a typical sexual assault victim. Prospective analyses indicated that personal risk perception does change in response to sexual victimization but also indicated that heightened risk perception may be an accurate assessment of risk that actually precedes victimization experience. Implications for the meaning of perceived similarity and perceptions of risk for sexual assault victims are discussed. 相似文献

Two experiments exploring the effects of social category membership on real-life helping behavior are reported. In Study 1, intergroup rivalries between soccer fans are used to examine the role of identity in emergency helping. An injured stranger wearing an in-group team shirt is more likely to be helped than when wearing a rival team shirt or an unbranded sports shirt. In Study 2, a more inclusive social categorization is made salient for potential helpers. Helping is extended to those who were previously identified as out-group members but not to those who do not display signs of group membership. Taken together, the studies show the importance of both shared identity between bystander and victim and the inclusiveness of salient identity for increasing the likelihood of emergency intervention. 相似文献

The Collaborative Assessment and Management of Suicidality (CAMS) is a novel clinical approach used to identify, assess, and manage suicidal outpatients (Jobes & Drozd, 2004). The results of a retrospective study evaluating the impact of CAMS versus treatment as usual (TAU) on suicidal outpatients are presented. Patients in the CAMS treatment group (n = 25) resolved their suicidality significantly more quickly than TAU patients (n = 30). CAMS was also significantly associated with decreased medical health care utilization in the 6 months after the start of suicide-related mental health treatment. These results provide promising preliminary support for the effectiveness of CAMS and a foundation for prospective research. 相似文献

These recommendations describe the minimum standard criteria for genetic counseling and testing of individuals and families
with fragile X syndrome, as well as carriers and potential carriers of a fragile X mutation. The original guidelines (published
in 2000) have been revised, replacing a stratified pre- and full mutation model of fragile X syndrome with one based on a
continuum of gene effects across the full spectrum of FMR1 CGG trinucleotide repeat expansion. This document reviews the molecular
genetics of fragile X syndrome, clinical phenotype (including the spectrum of premature ovarian failure and fragile X-associated
tremor-ataxia syndrome), indications for genetic testing and interpretation of results, risks of transmission, family planning
options, psychosocial issues, and references for professional and patient resources. These recommendations are the opinions
of a multicenter working group of genetic counselors with expertise in fragile X syndrome genetic counseling, and they are
based on clinical experience, review of pertinent English language articles, and reports of expert committees. These recommendations
should not be construed as dictating an exclusive course of management, nor does use of such recommendations guarantee a particular
outcome. The professional judgment of a health care provider, familiar with the facts and circumstances of a specific case,
will always supersede these recommendations. 相似文献

Two studies examined whether a criminal defendant's race influences Whites' sensitivity to legally relevant information. In Study 1, prosecution case strength ratings and guilt likelihood ratings were more sensitive to the strength of the defendant's alibi when he was Black than when he was White, if the experimental task was designed to elicit low processing motivation. Under high motivation, participants were equally sensitive to alibi strength, regardless of defendant race. In Study 2, the alibi strength manipulation was replaced with a manipulation of the effectiveness of the district attorney's cross-examination. As predicted, defense case strength ratings were more sensitive to the strength of the prosecutor's cross-examination with a Black defendant than with a White defendant-under low motivation. Under high motivation, sensitivity did not depend on defendant race. These results suggest that a Black defendant can elicit greater sensitivity to legally relevant information than will a White defendant. 相似文献

Children who experienced a highly stressful natural disaster, Hurricane Andrew, were interviewed within a few months of the event, when they were 3-4 years old, and again 6 years later, when they were 9-10 years old. Children were grouped into low, moderate, or high stress groups depending on the severity of the experienced storm. All children were able to recall this event in vivid detail 6 years later. In fact, children reported over twice as many propositions at the second interview as at the first. At the initial interview, children in the high stress group reported less information than children in the moderate stress group, but 6 years later, children in all three stress groups reported similar amounts of information. However children in the high stress group needed more questions and prompts than children in the other stress groups. Yet children in the high stress group also reported more consistent information between the two interviews, especially about the storm, than children in the other stress groups. Implications for children's developing memory of stressful events are discussed. 相似文献

Efforts to better understand bipolar spectrum disorders across ethnic groups are often hampered by the lack of commonly used self-report instruments to assess mania and depression in individuals who speak languages other than English. This article describes the translation into Spanish of 2 self-report measures of manic symptoms (i.e., the Internal State Scale and the Hypomanic Personality Scale) and 2 self-report measures of depression (i.e., the Inventory to Diagnose Depression and the Inventory to Diagnose Depression, Lifetime version). The authors translated these measures into Spanish and assessed their psychometric properties among bilingual college students (N = 88). Results suggest that the Spanish versions have psychometric properties comparable to the English versions of the instruments. 相似文献
