This study examined the psychometric properties of a questionnaire developed with the guidance of the socialization model of child behaviour to understand modifiable correlates of toddlers’ physical activity and sedentary behaviour. Findings are based on 118 parents (33.7 ± 4.9 years; 86% female) of toddlers (19.3 ± 2.7 months; 48% female) from Edmonton, Canada in The Parents’ Role in Establishing healthy Physical activity and Sedentary behaviour habits study (PREPS). The PREPS questionnaire encompassed 21 variables across the constructs of the socialization model of child behaviour. Of the nine variables assessed for internal consistency reliability, eight had good (α ≥ 0.70) reliability. Of the 15 continuous variables assessed for 1-week test–retest reliability, 10 had moderate (intra-class correlation = 0.50–0.74) and 5 had good (intra-class correlation ≥ 0.75) reliability. Of the six categorical variables assessed for 1-week test–retest reliability, two had fair (К = 0.21–0.40), one had moderate (К = 0.41–0.60), one had substantial (К = 0.61–0.80), and two had almost perfect (К = 0.81–1.00) reliability. Of the 12 sedentary behaviour variables assessed for convergent validity, 7 were significantly correlated with children’s screen time, of which three were small (r ≤ 0.29), two were medium (r = 0.30–0.49), and two were large (r ≥ 0.50) effect sizes.  相似文献

Many children fail to meet physical activity (PA) guidelines for health benefits. PA behaviours are complex and depend on numerous interrelated factors. The study aims to develop current understanding of how children from low Socio-economic environments within the UK use their surrounding built environments for PA by using advanced technology. The environment was assessed in 96 school children (7–9 years) using global positioning system (GPS) monitoring (Garmin Forerunner, 305). In a subsample of 46 children, the environment and PA were assessed using an integrated GPS and heart rate monitor. The percentage of time spent indoor, outdoor, in green and non-green environments along with time spent in moderate-to-vigorous PA (MVPA) in indoor and outdoor environments were assessed. A 2-by-2 repeated measures analysis of covariance, controlling for body mass index, BF%, assessed the environmental differences. The findings show that 42% of children from deprived wards of Coventry fail to meet PA guidelines, of which 43% was accumulated during school. Children engaged in more MVPA outdoor than indoor environments (P < 0.01) and a greater amount of time was spent in non-green environments (P < 0.01). Increased time outdoors was negatively associated with BF%. In conclusion, outdoor environments are important for health-enhancing PA and reducing fatness in deprived and ethnic children.  相似文献

The Special Collections Research Center at Johns Hopkins University received a Council on Library and Information Resources Hidden Collections grant from March 2013 to March 2014 for processing the archives of the Roland Park Company. The grant included partnerships between the Archives and Technical Services to create a Best Practices for EAC-CPF records, as well as a local high school history class to complete the required research. Rather than simplify International Standard Archival Authority Record For Corporate Bodies, Persons and Families and EAC-CPF for the students, project staff distilled them into discrete, easy-to-understand tasks that allowed for the production of controlled data in a high school environment.  相似文献

In post-secondary education, there is a widely-held belief in a “gold standard” for evaluative studies of curricular innovations. In this context, “appropriate” assessment is understood to refer to experimental designs and statistically significant differences in group outcomes. Yet in our evaluative study of a medical undergraduate program, we did not find these concepts to be particularly applicable. Based on our experience, we now feel that it is appropriate to assemble an eclectic mix of scientific findings, show how they have been used for program improvement, and articulate the program’s theoretical rationale and social significance. In the absence of statistically significant differences, this comprehensive argument can be used to justify the deployment of curricular innovations. The same may be true of other educational programs that target hard-to-measure changes in affective domains.  相似文献

A critical skill of childhood is learning social norms. We examine whether the generic pronouns “you” and “we,” which frame information as applying to people in general rather than to a specific individual, facilitate this process. In one pre-registered experiment conducted online between 2020 and 2021, children 4- to 9-year-old primarily living in the midwestern U.S. (N = 146, 75 girls, 71 boys, Mage = 7.14, SD = 1.69, 82% White) interpreted actions described with generic pronouns (vs. “I”) as normatively correct and selected the speaker who used generic pronouns as the rule-follower, particularly when generic pronouns were presented first. There were no significant effects of age. These results illustrate how generic pronouns influence how children discern unfamiliar norms and form interpersonal judgments.  相似文献
