The consistency of childhood sexual abuse (CSA) reporting was explored in this study. Two-hundred seventeen adolescents and young adults (ages 14-24) enrolled in urban health care clinics completed self-report questionnaires assessing CSA and other problem behaviors at enrollment and at 7 months. Results indicated that the stability of CSA self-report at two time points was poor (58% consistent nonreporters of CSA, 20% consistent reporters, 22% inconsistent reporters). Consistent and inconsistent reporters were differentiated on risk measures. Adolescents who endorsed more items from the CSA scale were five times more likely to be consistent reporters. In sum, adolescent CSA reporting was quite inconsistent over time. Using multi-item scales and assessing CSA at two time points enhances accuracy of reporting. 相似文献

The purpose of this article is to introduce the cross-disciplinary competency standards for work-related assessments, why they are needed and how they have been developed in New South Wales (NSW). Cross-disciplinary competency standards communicate the benchmarks for effective performance of work-related assessments. They outline what is expected of rehabilitation professionals, including the ability to apply and transfer competence across different conditions and workplace contexts. Outcomes in occupational rehabilitation are affected by the efficacy of the work-related assessments performed, which is dependent upon competent, clinical decision-making by rehabilitation professionals. However, in Australia, work-related assessment practice is not governed by universally accepted competency standards or by any competency-based training/education and assessment system. To enhance professional practice, WorkCover NSW has developed cross-disciplinary competency standards for work-related a ssessments. The competencies provide (i) quality standards for professional workplace training and development, (ii) benchmarks for assessing the competence of rehabilitation professionals, (iii) a framework for evidence-based practice, (iv) benchmarks for measuring service quality and (v) "real world" learning outcomes and assessment criteria for professional education programs. 相似文献

To examine correlates of the speed at which female soldiers carrying loads could cover 3.2 km on foot and traverse an obstacle course, 12 volunteers (mean +/- SD: 25.3 +/- 6 years, 166 +/- 7 cm, 61.3 +/- 7 kg) were timed over 3.2 km while carrying loads of 14, 27, and 41 kg, and while traversing an obstacle course with the two lighter loads. Pearson correlations showed that absolute VO_[2 max] and 3.2 km run time without a load were the best predictors of 3.2 km load carriage time for all loads. Also, larger subjects with greater muscle mass were able to carry the heaviest load faster than smaller, less muscular subjects, likely because the 41 kg load represented a smaller percentage of the former's bodyweight. Maximum number of sit-ups and push-ups, composite score of the Army Physical Fitness Test as well as body height were positively correlated with the speed at which some course segments were traversed. 相似文献

This paper deals with the issue of whether standardised psychological tests, in particular intelligence tests, are suitable for assessing ethnic minorities in a multicultural society. Three different levels of analysis are applied to address this question: the socio-political, the ethical and the test-theoretical level. The socio-political level of analysis highlights the obstacles ethnic minorities encounter when attempting to settle in a new society, and the measures that could be taken to remove these obstacles. The ethical level of analysis elucidates our point of view that: (1) universal and particular competencies both have clear roles in the lives of individuals and groups, but; (2) these can not always be reconciled in educational settings; which (3) calls for various choices: between certain political commitments (e.g. the right to cultural differences), and the consequences of these (e.g. excluding those who are different from full participation in specific, mainstream roles and functions). Central to the paper is our sense that the testing of ethnic minorities "tests" the limits and possibilities of intercultural education. 相似文献

Choice of Parametric Accelerated Life and Proportional Hazards Models for Survival Data: Asymptotic Results 总被引:1,自引:0,他引:1
We discuss the impact of misspecifying fully parametric proportional hazards and accelerated life models. For the uncensored case, misspecified accelerated life models give asymptotically unbiased estimates of covariate effect, but the shape and scale parameters depend on the misspecification. The covariate, shape and scale parameters differ in the censored case. Parametric proportional hazards models do not have a sound justification for general use: estimates from misspecified models can be very biased, and misleading results for the shape of the hazard function can arise. Misspecified survival functions are more biased at the extremes than the centre. Asymptotic and first order results are compared. If a model is misspecified, the size of Wald tests will be underestimated. Use of the sandwich estimator of standard error gives tests of the correct size, but misspecification leads to a loss of power. Accelerated life models are more robust to misspecification because of their log-linear form. In preliminary data analysis, practitioners should investigate proportional hazards and accelerated life models; software is readily available for several such models. 相似文献

Making patient safety the No. 1 priority at a hospital or clinic sounds like a easy task. It isn't. At one Oklahoma health system, an improved patient safety program is a massive effort requiring input and participation from every member of the staff. Figuring out how to convince employees that patient safety is their first priority means developing an extensive communication and education program. 相似文献

Securing excellent care and positive outcomes for seriously ill, high-risk patients requires extraordinary measures. A health system in Georgia is experiencing strong results by taking a team approach to health care with case managers, physicians and patients working together. 相似文献
