This study examined administration method (standard written administration vs. oral administration by an examiner) as a variable in influencing children's self-report test scores. Subjects included 139 students in grades 3–6, randomly assigned to one or the other administration condition. Subjects completed the Internalizing Disorders Evaluation Scale for Children (IDESC) according to the assigned administration method. Internal consistency estimates of each group were essentially similar. Mean IDESC scores of the two groups did not differ significantly from either a statistical or practical standpoint, based on t-test and effect size calculations. Results suggest that method of administration did not affect test performance. Implications for child assessment and future research are discussed. 相似文献

Urban communities are disproportionality impacted by issues such as community violence, leaving children at higher risk of trauma, and increased adverse childhood experiences. This applied study addresses a research-to-practice gap by demonstrating the longitudinal impact of a district-initiated, school-wide multitiered systems of support approach to universal instruction, intervention, and assessment—the Comprehensive Behavioral Health Model. Results from more than 1200 students over a 3-year period indicate that this universal, integrated approach is associated with improved outcomes for students with a demonstrated level of risk, with the greatest impact on students with risk of internalizing behaviors. The findings of this applied study highlight the benefits of a systemic approach and enhance the discourse on robust universal screenings that can identify needs and assets of children within urban communities. 相似文献

This article provides a “thick” understanding of how public school parents understand their decision to opt their children out of standardized tests. In it, Amy Shuffelton draws from qualitative research interviews with Chicago parents to explore how three mothers connected opting out of standardized testing to their broader commitments to public schools. In probing the democratic potential of their logic, Shuffelton points to avenues of hope for democratic and equitable public schooling. As scholars have argued on multiple grounds, public schools have generally preserved inequitable power relations and resource allocations rather than changed them, and this happens in part because of parental resistance to reforms they believe to be detrimental to the interests of their children. Precisely because privileged parents have and implement the power to use schooling to pass advantages to their own children, however, it is important to consider when and why some of these parents instead see reason to build a public school system that shares those advantages widely. Putting these parents' explanations for opting out of testing into conversation with ideas about the democratic public in texts by John Dewey and Bonnie Honig, Shuffelton finds potential pathways, as well as hurdles, to reviving commitment to public schooling. 相似文献

The Acute Exercise-Induced Inflammatory Response: A Comparison of Young-Adult Smokers and Nonsmokers

Purpose: This study examined postexercise inflammatory and leukocyte responses in smokers and nonsmokers, as well as the effects of cigarette smoking on the acute postexercise inflammatory and leukocyte response in habitual smokers. Method: Eleven recreationally active male smokers and 11 nonsmokers matched for age and aerobic fitness were familiarized and underwent baseline fitness testing. Participants then completed 40 min of cycling at 50% peak aerobic workload. Smokers performed 2 randomized exercise sessions, including an acute postexercise smoking condition (2 cigarettes in 15 min of 12 mg tar and 1 mg nicotine) and a no-smoking condition, while nonsmokers performed 1 exercise session without smoking. Venous blood was obtained preexercise and postexercise for analysis of interleukin (IL)-6, IL-1 receptor antagonist (ra), tumor necrosis factor-alpha (TNF-α), and c-reactive protein (CRP). Results: No differences existed between groups for resting CRP (d = 0.25–0.46; p = .374–.617). Despite no baseline difference (d = 0.03–0.07; p = .141–.70), exercise-induced increases were observed for IL-1 ra in smokers (d = 0.50; p = .024–.033), which was not observed in the never-smoker group. No between-group difference was observed for IL-6 across all points (d = 0.09–0.5; p = .102–.728); however, all groups observed significant within-group change (d = 0.27–1.09; p = .001–.042). Further, TNF-α for smokers smoking was elevated above both smokers not smoking and nonsmokers at baseline and across the protocol (d = 1.20–1.80; d = 0.20–1.0; p = .001–.035). Additionally, a marked postexercise increase in leukocyte and neutrophil concentrations was evident in smokers smoking compared with nonsmokers and smokers not smoking as indicated by a moderate-to-large effect size (d = 0.72; d = 0.78). Conclusion: Consequently, male smokers exhibit an altered postexercise proinflammatory profile compared with age- and fitness-matched nonsmokers. 相似文献

The purpose of this study was to investigate potential differences in emotional expression and counterfactual thought between bronze and silver Olympic medallists. In Study 1, 468 photographs (156 gold medallists, 156 silver medallists, 156 bronze medallists) were obtained of Olympic medal winners standing on the podium at the 2016 Summer Olympic Games, and 20 students rated the level of expressed happiness in each photograph. The students were blind to the outcome of the event and an average score for each photograph was used in data analysis. Results showed that gold medallists displayed greater levels of happiness than silver medallists but that silver and bronze medallists showed little difference in their expressed happiness. In Study 2, 192 quotations from bronze and silver medallists were obtained from news outlets, and 20 students rated the expression of counterfactual thought in each quotation. Results showed that compared to bronze medallists, silver medallists had more counterfactual thoughts overall, more counterfactual thoughts about how things could have gone better, and more counterfactual thoughts about their opponents’ behaviour. Overall, findings indicate that counterfactual thoughts differ between bronze and silver medallists, but that differences in expressed emotion are likely to be trivial or negligible. 相似文献

This study examined the association of gestational diabetes mellitus (GDM), prenatal, and postnatal maternal depressive symptoms with externalizing, internalizing, and autism spectrum problems on the Preschool Child Behavior Checklist in 2379 children aged 4.12 ± 0.60 (48% female; 47% White, 32% Black, 15% Mixed Race, 4% Asian, <2% American Indian/Alaskan Native, <2% Native Hawaiian; 23% Hispanic). Data were collected from the NIH Environmental influences on Child Health Outcomes (ECHO) Program from 2009-2021. GDM, prenatal, and postnatal maternal depressive symptoms were each associated with increased child externalizing and internalizing problems. GDM was associated with increased autism behaviors only among children exposed to perinatal maternal depressive symptoms above the median level. Stratified analyses revealed a relation between GDM and child outcomes in males only. 相似文献
