OBJECTIVE: Children who experience multiple victimizations (referred to in this paper as poly-victims) need to be identified because they are at particularly high risk of additional victimization and traumatic psychological effects. This paper compares alternative ways of identifying such children using questions from the Juvenile Victimization Questionnaire (JVQ). METHODS: The JVQ was administered in a national random digit dial telephone survey about the experiences of 2,030 children. The victimizations of children 10-17 years old were assessed through youth self-report on the JVQ and the victimizations of children 2-9 assessed through JVQ caregiver proxy report. RESULTS: Twenty-two percent of the children in this sample had experienced four or more different kinds of victimizations in separate incidents (what we term poly-victimization) within the previous year. Such poly-victimization was highly associated with traumatic symptomatology. Several ways of identifying poly-victims with the JVQ produced roughly equivalent results: a simple count using the 34 victimizations screeners, a count using a reduced set of only 12 screeners, and the original poly-victimization measure using follow-up questions to identify victimizations occurring during different episodes. CONCLUSION: Researchers and clinicians should be taking steps to identify poly-victims within the populations with which they work and have several alternative ways of doing so.  相似文献

This article includes a multimethod, multisource analysis and synthesis of the degree to which contemporary family-oriented early intervention policies and practices are family centered. Federal laws and legislation, state-level policy positions, and the viewpoints of service providers and consumers were analyzed as part of the study. The findings, taken together, indicate a movement toward adoption of family-centered early intervention policies and practices at the different levels of analysis. There are, however, discrepancies between what state-level policymakers and "street-level" providers and consumers see as current beliefs and practices within states.  相似文献

验证收缩骨骼肌细胞葡萄糖转运蛋白4(GLUT4)基因的表达在转录水平上是否受转录抑制子Ⅱ型HDAC5蛋白(简写为HDAC5)的调节。研究运用运动模拟信号5-氨基-4-甲酰胺咪唑核糖核苷酸(AICAR)和HDACs抑制剂SCRIPTAID孵育骨骼肌细胞。用蛋白印迹技术测定HDAC5蛋白表达,定量RT-PCR法检测GLUT4 mRNA表达。与无AICAR的对照组相比,AICAR组骨骼肌细胞内HDAC5减少了29%,并伴随有124% GLUT4 mRNA的增加,但肌细胞内HDAC5的蛋白总量无变化;使用HDACs抑制剂SCRIPTAID刺激骨骼肌细胞能够明显增加核心组蛋白乙酰化水平和上调GLUT4基因的表达。这些结果提示,通过AICAR和SCRIPTAID分别减少或抑制核HDAC5均能上调骨骼肌细胞GLUT4基因的转录,HDAC5可能在转录水平上对肌肉收缩引起的GLUT4基因的表达起着重要的调节作用。  相似文献

OBJECTIVE: To assess the utility and performance of the 34-item Juvenile Victimization Questionnaire (JVQ) in eliciting the recent victimization experiences of a national sample of children ages 2-17. METHOD: The JVQ was administered in a national random digit dial telephone survey about the experiences of 2,030 children. The experiences of children 10-17 years old were assessed through youth self-report on the JVQ, and the experiences of children 2-9 assessed through JVQ caregiver proxy report. RESULTS: Large numbers of recent victimizations were disclosed using the JVQ (71% of the sample reporting at least one victimization in the last year, with an average of 2.63 victimizations per child). There were few indicators of respondent confusion and little resistance to even the most sensitive questions. In a test of construct validity, endorsements of JVQ items correlated well with measures of traumatic symptoms. The instrument showed adequate test-retest reliability in a 3 to 4 week re-administration. Large numbers of victimizations were reported across the spectrum of ages, and there were no major discontinuities between the self-reports and proxy reports, suggesting that caregivers provided generally adequate and comparable information to child self-reports about the experiences of children under the age of 10. CONCLUSION: The JVQ has potential for use in future epidemiological research as well as clinical evaluation concerning the victimization of children.  相似文献

The purposes of this study were to describe the structure of events during cooperative learning activities—Friday discussion sessions—in a graduate-level thermodynamics course and to understand what these activities meant to the students. First, we describe the structure of Friday discussion sessions in our classroom, which were used to focus student attention on conceptual issues rather than algorithmic problem solving. Second, we delineate findings which emerge from the perspective of the students. We found that cooperative learning activities move students away from rote learning strategies and toward more meaningful strategies which allowed them to integrate concepts over the entire semester. In addition, we discovered that the sharing of insights and ideas between students leads to the development of interpersonal skills and communication skills which the students perceive as an important component of the Friday discussion sessions. Implications for further classroom use, low-status versus high-status students, and assessment are discussed. J Res Sci Teach 34: 819–835, 1997.  相似文献

This paper assesses how many children and youth have had exposure to programs aimed at preventing various kinds of violence perpetration and victimization. Based on a national sample of children 5–17, 65% had ever been exposed to a violence prevention program, 55% in the past year. Most respondents (71%) rated the programs as very or somewhat helpful. Younger children (5–9) who had been exposed to higher quality prevention programs had lower levels of peer victimization and perpetration. But the association did not apply to older youth or youth exposed to lower quality programs. Disclosure to authorities was also more common for children with higher quality program exposure who had experienced peer victimizations or conventional crime victimizations. The findings are consistent with possible benefits from violence prevention education programs. However, they also suggest that too few programs currently include efficacious components.  相似文献

To assess whether youth are upset by being asked questions about sensitive kinds of abuse, victimization, family maltreatment, and sexual victimization in the course of standard epidemiological surveys. A national sample of youth aged 10–17 were interviewed on the telephone by experienced interviewers as part of the National Survey of Children Exposed to Violence. At the end they were asked whether answering questions had upset them. Of the youth interviewed, 4.5% reported being at all upset and 0.8% reported being pretty or a lot upset. However, only a minority of those upset, .3% of the total sample, said they would not participate again had they known about the content. But even in this group, the regret about participation was mostly due to the length of the survey, not the types of questions being asked. Thus, asking about exposure to abuse and sensitive kinds of victimization in standard interview surveys is associated with low levels of respondent upset due to the nature of the questions.  相似文献
