Following terrorist events, teachers and nonteaching school personnel are important in helping children recover, yet little is known about their willingness to assist with this. We surveyed 399 employees from a Washington, D.C.‐area school district following terror attacks (September 11, 2001, attacks; sniper shootings) about their exposure, adjustment, interest, and involvement in psychosocial interventions. Between 10% and 27% experienced one or more symptoms of posttraumatic stress (depending on category of symptom) in the month prior to the survey. Regression analyses revealed that peritraumatic distress, behavior change, and posttraumatic growth predicted interest in information on psychosocial interventions. Feeling prepared, adaptively managing work responsibilities, and perceiving an increase in student problems were related to intervening with students. Implications for school preparedness are discussed. © 2010 Wiley Periodicals, Inc.  相似文献

Evidence of the relative age effect in football in Australia     

Robin van den Honert 《Journal of sports sciences》2013,31(13):1365-1374

Abstract

The birth date distributions of elite male and female footballers in Australia, from junior youth (age 14 and upwards) to senior (professional) players, were examined. A statistically significant relative age effect was found among junior male players, reducing in effect with increasing age. An inter-year relative age effect that became apparent among the players at national level in the Under-17 and Under-20 age groups, due to the timing of the respective World Cups for those age groups, was also identified. It is conjectured that this might lead to players born in certain years having a curtailed pathway in the elite game, leading to drop-out among this very elite group. In the case of women elite players, no significant relative age effect was found among youth players, possibly due to less fierce competition for places, although a significant effect was found to exist at senior elite level.  相似文献   

Development and validation of the Decision-Specific Reinvestment Scale     

Noel P. Kinrade  Robin C. Jackson  Kelly J. Ashford  Daniel T. Bishop 《Journal of sports sciences》2013,31(10):1127-1135

Abstract

Items from the Reinvestment Scale were modified to create a decision-specific version of the scale. Principal components analysis of responses from 165 participants revealed one-, two-, three-, and four-factor solutions for the Decision-Specific Reinvestment Scale. Confirmatory factor analysis of responses from a second sample of 111 participants revealed that a 13-item two-factor solution showed the best fit. The first factor comprised six items referring to conscious monitoring of the process involved in making a decision, and was termed decision reinvestment. The second factor, decision rumination, comprised seven items related to focus on negative evaluations of previous poor decisions. In an initial assessment of predictive validity, Decision-Specific Reinvestment Scale scores of 59 skilled team sport players were found to be highly correlated with coaches' ratings of players' tendency to choke under pressure (r = 0.74), with high Decision-Specific Reinvestment Scale scores indicating greater susceptibility to poor decision-making under pressure. It was concluded that the Decision-Specific Reinvestment Scale highlights a performer's predisposition to engage in behaviours detrimental to performance under pressure, namely decision reinvestment and decision rumination.  相似文献

Test–retest reliability of a battery of field-based health-related fitness measures for adolescents     

David R. Lubans  Philip Morgan  Robin Callister  Ronald C. Plotnikoff  Narelle Eather  Nicholas Riley 《Journal of sports sciences》2013,31(7):685-693

Abstract

The main aim of this study was to determine the test–retest reliability of existing tests of health-related fitness. Participants (mean age 14.8 years, s = 0.4) were 42 boys and 26 girls who completed the study assessments on two occasions separated by one week. The following tests were conducted: bioelectrical impedance analysis (BIA) to calculate percent body fat, leg dynamometer, 90° push-up, 7-stage sit-up, and wall squat tests. Intra-class correlation (ICC), paired samples t-tests, and typical error expressed as a coefficient of variation were calculated. The mean percent body fat intra-class correlation coefficient was similar for boys (ICC = 0.95) and girls (ICC = 0.93), but the mean coefficient of variation was considerably higher for boys than girls (22.2% vs. 12.2%). The boys' coefficients of variation for the tests of muscular fitness ranged from 9.0% for the leg dynamometer test to 26.5% for the timed wall squat test. The girls' coefficients of variation ranged from 17.1% for the sit-up test to 21.4% for the push-up test. Although the BIA machine produced reliable estimates of percent body fat, the tests of muscular fitness resulted in high systematic error, suggesting that these measures may require an extensive familiarization phase before the results can be considered reliable.  相似文献   

Accelerometer and GPS Data to Analyze Built Environments and Physical Activity     

Kosuke Tamura  Jeffrey S. Wilson  Keith Goldfeld  Robin C. Puett  David B. Klenosky  William A. Harper 《Research quarterly for exercise and sport》2013,84(3):395-402

ABSTRACT

Purpose: Most built environment studies have quantified characteristics of the areas around participants’ homes. However, the environmental exposures for physical activity (PA) are spatially dynamic rather than static. Thus, merged accelerometer and global positioning system (GPS) data were utilized to estimate associations between the built environment and PA among adults. Methods: Participants (N = 142) were recruited on trails in Massachusetts and wore an accelerometer and GPS unit for 1–4 days. Two binary outcomes were created: moderate-to-vigorous PA (MVPA vs. light PA-to-sedentary); and light-to-vigorous PA (LVPA vs. sedentary). Five built environment variables were created within 50-meter buffers around GPS points: population density, street density, land use mix (LUM), greenness, and walkability index. Generalized linear mixed models were fit to examine associations between environmental variables and both outcomes, adjusting for demographic covariates. Results: Overall, in the fully adjusted models, greenness was positively associated with MVPA and LVPA (odds ratios [ORs] = 1.15, 95% confidence interval [CI] = 1.03, 1.30 and 1.25, 95% CI = 1.12, 1.41, respectively). In contrast, street density and LUM were negatively associated with MVPA (ORs = 0.69, 95% CI = 0.67, 0.71 and 0.87, 95% CI = 0.78, 0.97, respectively) and LVPA (ORs = 0.79, 95% CI = 0.77, 0.81 and 0.81, 95% CI = 0.74, 0.90, respectively). Negative associations of population density and walkability with both outcomes reached statistical significance, yet the effect sizes were small. Conclusions: Concurrent monitoring of activity with accelerometers and GPS units allowed us to investigate relationships between objectively measured built environment around GPS points and minute-by-minute PA. Negative relationships between street density and LUM and PA contrast evidence from most built environment studies in adults. However, direct comparisons should be made with caution since most previous studies have focused on spatially fixed buffers around home locations, rather than the precise locations where PA occurs.  相似文献   

Reconceptualizing the Sources of Teaching Self-Efficacy: a Critical Review of Emerging Literature     

David B. Morris  Ellen L. Usher  Jason A. Chen 《Educational Psychology Review》2017,29(4):795-833

Teachers’ efficacy beliefs are thought to influence not only their motivation and performance but also the achievement of their students. Scholars have therefore turned their attention toward the sources underlying these important teacher beliefs. This review seeks to evaluate the ways in which researchers have measured and conceptualized the sources of teaching self-efficacy across 82 empirical studies. Specifically, it aims to identify what can be inferred from these studies and what important questions still remain about the origins of teachers’ efficacy beliefs. Results indicate that a number of methodological shortcomings in the literature have prevented a clear understanding of how teachers develop a sense of efficacy. Nonetheless, insights gleaned from existing research help to refine, and to expand, theoretical understandings of the sources of self-efficacy and their influence in the unique context of teaching. Implications for future research and practice are addressed.  相似文献
