Discriminant analysis was used to examine factors that influenced the educational diagnoses of a sample of 80 referred students in grades 1 to 6. All students had WISCR Full Scale IQs between 63 and 75, which includes the range of scores that is ±2 SEm around the cutoff value of 69 used by the student's school district to define the upper limit of the mildly retarded classification. The results indicate that the recommendations made by the multidisciplinary teams were associated primarily with the level of the Full Scale IQ. 相似文献

A factor analysis of the abbreviated Conners Teacher Rating Scale (CTRS) was completed using a sample of 108 regular and special education students. Two factors accounted for 69.5% of the total response variance: Factor I consisted of items describing attention deficits and motor activity, and Factor II consisted of items describing excessive affective reactions. It is suggested that the abbreviated CTRS be interpreted with respect to its latent structure, rather than to one global score as has been common practice. 相似文献

The test scores of 153 referred students who received inconsistent placements according to California's discrepancy criterion, which does not take regression into account (standard score distribution procedure), were reanalyzed using a procedure that accounts for regression. Students involved in these MDT discretionary decisions were placed into one of three groups: ineligible (originally met discrepancy criterion, but not placed), resource class (originally did not meet discrepancy criterion, but placed in a less restrictive pull-out program), and special day class (originally did not meet discrepancy criterion, but placed in a more restrictive, essentially full-time special education class). All of these placements were inconsistent with the nonregressed ability-achievement discrepancy criterion the MDTs used at the time of the IEP meeting. To evaluate how many of these students could be considered to be underachieving when regression is considered, regressed discrepancy scores were computed using the students' scores on the WISC-R and one or more of the following achievement tests: WRAT, PIAT, and W-J. Regression “accounted” for a significant proportion of the inconsistent placements in all three groups: ineligible (25.0%), resource class (31.5%), and special day class (46.9%). Implications for professional practice and public policy are discussed. 相似文献

Recent concern about school violence has increased demands on school psychologists to respond to safety concerns on their school campuses. In this study, 123 school psychologists responded to a survey about their perceptions, experiences, and readiness to meaningfully address school violence. School psychologists reported that they do not worry about their personal safety at school (78%), but most felt unprepared to deal with school violence (73%) and had received no specialized training in this area (85%). A principal components analysis of the types of violence school psychologists perceived to occur on their campuses identified a range of incidents from bullying to antisocial behavior. School psychologists working in inner-city schools were more likely to believe that their schools had high levels of violence (45.6%) compared with those working in urban-not inner-city (14.3%), suburban (4.9%), or rural (0%) schools. Recommendations to prepare school psychologists to help prevent, reduce, and respond to campus violence are discussed. © 1996 John Wiley & Sons, Inc. 相似文献

Background:Osteoarthritis is one of the leading causes of pain and disability worldwide,and a large percentage of patients with osteoarthritis are individuals who are also obese.In recent years,a series of animal models have demonstrated that obesity-inducing diets can result in synovial joint damage(both with and without the superimposition of trauma),which may be related to changes in percentage of body fat and a series of low-level systemic inflammatory mediators.Of note,there is a disparity between whether the dietary challenges commence at weaning,representing a weanling onset,or at skeletal maturity,representing an adult onset of obesity.We wished to evaluate the effect ofthe dietary exposure time and the age at which animals are exposed to a high-fat and high-sucrose(HFS) diet to determine whether these factors may result in disparate outcomes,as there is evidence suggesting that these factors result in differential metabolic disturbances.Based on dietary exposure time,we hypothesized that rats fed an HFS diet for 14 weeks from weaning(HFS Weanling) would demonstrate an increase in knee joint damage scores,whereas rats exposed to the HFS diet for 4 weeks,starting at 12 weeks of age(HFS Adult) and rats exposed to a standard chow diet(Chow)would not display an increase in knee joint damage scores.Methods:Male Sprague-Dawley rats were fed either an HFS diet for 14 weeks from weaning(HFS Weanling) or an HFS diet for 4 weeks,starting at 12 weeks of age(HFS Adult).At sacrifice,joints were scored using the modified Mankin Criteria,and serum was analyzed for a defined subset of inflammatory markers(Interleukin-6,leptin,monocyte chemoattractant protein-1,and tumor necrosis factorα).Results:When the HFS Weanling and HFS Adult groups were compared,both groups had a similar percent of body fat,although the HFS Weanling group had a significantly greater body mass than the HFS Adult group.The HFS Weanling and HFS Adult animals had a significant increase in body mass and percentage of body fat when compared to the Chow group.Although knee joint damage scores were low in all 3 groups,we found,contrary to our hypothesis,that the HFS Adult group had statistically significant greater knee joint damage scores than the Chow and HFS Weanling groups.Furthermore,we observed that the HFS Weanling group did not have significant differences in knee joint damage scores relative to the Chow group.Conclusion:These findings indicate that the HFS Weanling animals were better able to cope with the dietary challenge of an HFS diet than the HFS Adult group.Interestingly,when assessing various serum proinflammatory markers,no significant differences were detected between the HTS Adult and HFS Weanling groups.Although details regarding the mechanisms underlying an increase in knee joint damage scores in the HFS Adult group remain to be elucidated,these findings indicate that dietary exposure time maybe less important than the age at which an HFS diet is introduced.Moreover,increases in serum proinflammatory mediators do not appear to be directly linked to knee joint damage scores in the HFS Weanling group animals but may be partially responsible for the observed knee joint damage in the adults over the very short time of exposure to the HFS diet. 相似文献
