Analysis Mean and standard deviations and the percentage of the children’s response for each skill were calculated. Intra-class correlation coefficient (ICC) was computed for the analysis of the test-retest reliability of the LOC and OC subscale scores, as well as for the total PMSC-GR scores ( Cicchetti

Statistical Analysis Reliability of specific activities was assessed by calculating Spearman correlation coefficients (ρ) between the pre- and post-survey responses for each individual activity on each PA survey. Reliability estimates were also calculated stratified by sex

distribution using the Shapiro–Wilk normality test. Differences between the 2 groups were tested using an unpaired t test. Student’s and Mann–Whitney tests were used for parametric and nonparametric samples, respectively. A P value of <.05 was considered significant. The correlation analyses used Spearman

bedtime on the weekend?” Potential answers were in half hour increments from 20:00 to 04:00. Statistical Analysis Associations between self-reported and actigraphy-measured bedtimes were evaluated with Pearson correlation. Bland-Altman plots were used to assess inter-method agreement ( Bland & Altman

(Table  1 ). Repeated-measures ANOVA suggested that walking decreased significantly from T1 to T2 and from T2 to T3 ( F [1,121] = 17.39, p  < .01). Also, depressive symptoms also changed over time ( F [1,121] = 25.71, p  < .01). The correlation coefficients among the measures of depressive symptoms

. The three 1RM sessions were separated by 48 hr, with an intraclass correlation coefficient (ICC) ≥ .96. The highest load achieved among the three sessions was used for analysis in each exercise. Total strength was determined by the sum of the three exercises. Body Composition Spectral bioelectrical

vertical jump) and three object control skills (catch, overhand throw and kick) were assessed. Reliability for these skills (test-retest reliability) has been previously established (Intraclass Correlation Coefficient [ICC] = >0.70) ( Department of Education, 1996 ). Each skill is comprised of observable
