本研究对总装备部·绵阳八一帐篷学校的小学生进行创伤症状调查研究,了解震后一年半小学生的心理健康状况。方法:使用儿童创伤症状量表简版(TSCC-A)对八一帐篷学校3~6年级小学生进行评估。结果:(1)八一帐篷学校的小学生震后一年半最为突出的创伤症状是焦虑,其次为抑郁和分离症状;(2)在创伤症状得分上不存在性别差异性,但是存在年级差异性,三年级学生创伤症状得分均低于其他年级学生;(3)震后一年半学生创伤症状比震后半年学生创伤症状有所减轻。结论:灾区小学生心理健康状况仍存在一些问题,焦虑、抑郁等症状仍比较明显,还应进行持续的心理危机干预。  相似文献

Recoding processes can influence the Implicit Association Test (IAT; Greenwald, McGhee, & Schwartz, 1998) in a way that impedes an unequivocal interpretation of the resulting compatibility effects. We present a modified version of the IAT that aims to eliminate recoding, the IAT-RF (short for “IAT–recoding free”). In the IAT-RF, compatible and incompatible assignments of categories to responses switch randomly between trials within a single experimental block. Abandoning an extended sequence of consistent category–response mappings undermines recoding processes in the IAT-RF. Two experiments reveal that the IAT-RF is capable of assessing compatibility effects between the nominally defined categories of the task and effectively prevents recoding. By enforcing a processing of the stimuli in terms of their task-relevant category membership, the IAT-RF eliminates the confounding of compatibility effects with task switch costs and becomes immune against biased selections of stimuli.  相似文献

We present selected initial results from a study investigating the effects of school restructuring and reform activities on outcomes for students who are identified as having serious emotional and behavioral disabilities. A review of the literature revealed six key areas of reform for investigation: accountability, governance, parent involvement, includedness, curriculum and instruction, and pro-social discipline. Ten schools (five elementary, two K-8, one middle, and two high schools) actively engaged in school restructuring and reform efforts were selected to participate in the study, and their status related to these six areas is presented. Characteristics of the students identified as having emotional and behavioral disabilities and served in these schools in special education settings (N = 116) are described. Results from the administration of standardized assessments revealed that these students have significant levels of emotional and behavioral disabilities that impair their functioning at school and at home. Further, school staff are providing the majority of counseling services to these students during the school day, with non-school professionals providing services to 25% of the students.  相似文献

The concordance between parent reports of children's mental health services and medical and administrative service records were assessed in a field test of the Services Assessment for Children and Adolescents (SACA) interview instrument. Service use reports from primary caregivers, usually mothers, for their child's emotional or behavioral problems were compared against inpatient, outpatient, and school records in St. Louis, one of the pilot sites for the Multi-Site Study of Service Use, Need, Outcomes and Costs in Child and Adolescent Populations (UNOCCAP). A global any use service variable, comprised of inpatient, outpatient, and school reports, yielded an overall service use concordance kappa of .76 between parent reports and records. Parent reports of inpatient hospitalization services using the SACA yielded the highest agreement with medical records, with kappa statistics of 1.00 for use of any inpatient hospital care and for medication use. Parent reports of specific inpatient services concurred with medical records more moderately, yielding kappas from .50 to .66. Reports of any outpatient mental health services yielded variable rates of agreement, with kappas ranging from .67 for any use of outpatient care, to .66 for medication use, to negligible kappas for specific treatments. Parent reports of school services were weakly related to records for most services, except for moderate agreement (.48) on placement in special classrooms for emotional or behavioral problems. Family burden or impact discriminated more powerfully than other variables between respondents who concurred with records and those who did not.  相似文献

In the United States, judicialrulings that unrealistically addressed the complexityof cases and demonstrated limited understanding ofprinciples, helped to create a legal quagmire whichlegislatures had to confront. Moreover, thelegislative response was often slow and inadequate interms of both the scope and clarity of the laws. However, since the 1970s, progress has been made onmany fronts, particularly in regard to advancedirectives dealing with end-of-life decisions. Thedebate over physician-assisted suicide has spawned arepetition of moral and legal arguments. Thoseagainst legalization have failed to make a realisticappraisal of the dilemmas facing patients and theirfamilies in an age of technological medicine deliveredin the context of the marketplace. The underlyingproblem is a system in dire need of reform that willno longer treat health care as a commodity of themarketplace and provide universal health care. Terminal care as an integral part of health care willsubstantially benefit from such reforms because amajor obstacle to comprehensive palliative care is thecondition of the present system.  相似文献

The purpose of this study was to evaluate Denizli midwives’ self-reported knowledge of genetic diseases and genetic counseling. Data was collected on forms that obtained information about midwives approaches to basic genetics, genetic disorders, and genetic counseling (response rate = 70.1%). The highest response rate of midwives describing themselves as “knowledgeable” about basic genetic information was for mitosis and meiosis with 4.8%, about genetic disorders was for phenylketonuria with 61.1%, and about genetic counseling was for recommending ultrasonography during pregnancy with 98.1%. The source for basic genetics information for 56.4% of participants was in their school level classes. None of the midwives felt that they had sufficient knowledge about genetic counseling or screening and 76.4% would like to attend an educational course. Even though the midwives have recognized their knowledge deficit they occasionally give genetic counseling. As a result of this study a genetics course is planned for midwives so they can actively participate in the prevention and early diagnosis of genetic diseases.  相似文献

The report from President George W. Bush’s New Freedom Commission on Mental Health (NFC), Achieving the Promise: Transforming Mental Health Care in America(2003), proposes goals and recommendations for improving mental health services. This report has significant implications for the delivery of mental health services through the schools. A focused discussion of the potential opportunities and challenges of implementing NFC recommendations related to school-based mental health is presented. Strategies for addressing five key areas at the intersection of school mental health and the Commission’s recommendations include: stigma reduction, suicide prevention, expansion and improvement of school mental health, and screening and treatment of co-occurring mental health and substance abuse disorders.  相似文献
