Intraday reliability, sensitivity, and minimum detectable change of national physical fitness measurement for preschool children in China.

ABSTRACT: China General Administration of Sport has published and adopted the National Physical Fitness Measurement (NPFM-preschool children version) since 2000. However, studies on intraday reliability, sensitivity, and minimum detectable change (MDC) are lacking. This study aimed to investigate and compare the reliability, sensitivity, and MDC values of NPFM in preschool children between the ages of 3.5 to 6 years. Six items of NPFM including 10-m shuttle run, standing long jump, balance beam walking, sit-and-reach, tennis throwing, and double-leg timed hop, were tested for 209 Chinese kindergarten children in Beijing in the morning. Intraday relative reliability was tested using intraclass correlation coefficient (ICC3,1) with a 95% confidence interval while absolute reliability was expressed in standard error of measurement (SEM) and percentage of coefficient of variation (CV%). Test sensitivity was assessed by comparing the smallest worthwhile change (SWC) with SEM, while MDC values with 95% confidence interval (MDC95) were established. Measurements in most groups, except 10-m shuttle run test (ICC3,1: 0.56 to 0.74 [moderate]) in the 3.5 to 5.5-year-old groups, balance beam test in 4- and 5-year-old (ICC3,1: 0.33 to 0.35 [poor]) and 5.5-year-old (ICC3,1 = 0.68 [moderate]) groups, and double-leg timed hop test (ICC3,1 = 0.67 [moderate]) in the 4.5-year-old group, demonstrated good to excellent relative reliability (ICC3,1: 0.77 to 0.97). The balance beam walking test showed poor absolute reliability in all the groups (SEM%: 11.76 to 22.28 and CV%: 15.40 to 24.78). Both standing long jump and sit-and-reach tests demonstrated good sensitivity (SWC > SEM) in all subjects group, boys, and girls. Pairwise comparison revealed systematic bias with significantly better performance in the second trial (p<0.01) of all the tests with moderate to large effect size.

Project description:The lack of standardized criteria for measuring therapeutic response is a major obstacle to the development of new therapeutic agents for chronic graft-versus-host disease (cGVHD). National Institutes of Health (NIH) consensus criteria for evaluating therapeutic response were published in 2006. We report the results of 4 consecutive pilot trials evaluating the feasibility and estimating the interrater reliability and minimum detectable change of these response criteria. Hematology-oncology clinicians with limited experience in applying the NIH cGVHD response criteria (n = 34) participated in a 2.5-hour training session on response evaluation in cGVHD. Feasibility and interrater reliability between subspecialty cGVHD experts and this panel of clinician raters were examined in a sample of 25 children and adults with cGVHD. The minimum detectable change was calculated using the standard error of measurement. Clinicians' impressions of the brief training session, the photo atlas, and the response criteria documentation tools were generally favorable. Performing and documenting the full set of response evaluations required a median of 21 minutes (range: 12-60 minutes) per rater. The Schirmer tear test required the greatest time of any single test (median: 9 minutes). Overall, interrater agreement for skin and oral manifestations was modest; however, in the third and fourth trials, the agreement between clinicians and experts for all dimensions except movable sclerosis approached satisfactory values. In the final 2 trials, the threshold for defining change exceeding measurement error was 19% to 22% body surface area (BSA) for erythema, 18% to 26% BSA for movable sclerosis, 17% to 21% BSA for nonmovable sclerosis, and 2.1 to 2.6 points on the 15-point NIH Oral cGHVD scale. Agreement between clinician-expert pairs was moderate to substantial for the measures of functional capacity and for the gastrointestinal and global cGVHD rating scales. These results suggest that the NIH response criteria are feasible for use, and these reliability estimates are encouraging, because they were observed following a single 2.5-hour training session given at multiple transplant centers, with no opportunity for iterative training and calibration. Research is needed to evaluate inter- and intrarater reliability in larger samples, and to evaluate these response criteria as predictors of outcomes in clinical trials.
