To determine the between-visit reliability of an accelerometer as a measure of lower- extremity impact acceleration at a variety of gait speeds in children.
The reliability of SLAM was demonstrated with an inter-rater reliability and an inter-visit reliability of 0.86 and 0.73, respectively, and findings for the SLAM-R were similar (0.78 and 0.85, respectively).
The multi-stage probability sampling scheme, the visit, and the reliability of coding and data entry for NAMCS and NHAMCS have been detailed elsewhere [15].
A second visit for testing reliability during the main study was not conducted due to logistic reasons.
Mid-point reliability visits were completed with each data collector and the "gold standard" rater or the author to ensure inter-rater agreement continued to exceed 80% agreement within one scale point.
The earlier study by Kleinman et al. used screening and baseline visits to evaluate reliability and convergent validity of the FSS with other outcomes [ 18].
The second visit during test-retest reliability was 3-48.5 3-48.5after thoursrst (N = 307).
Sky will also try to reduce the need for service visits by increasing the reliability of its set-top boxes, which are currently around 85% reliable, the BBC understands.
Data from patients' initial consultations with the surgeon, an intermediate assessment, and then again at patients' preoperative orientation visits contributed to the reliability analysis.
The aims were: to develop and validate an outcome measure, the SLEDAI-2K Responder Index-50 (S2K RI-50), able to capture partial improvement, ≥50%, in each of the active descriptors at subsequent visits; to test the reliability of S2K RI-50; and to evaluate S2K RI-50 sensitivity to response at 6 and 12 months.
From the mean of the four visits we estimated the reliability of iron and red meat intake for individual participants using the formula 1/[1+(ratio/4)]×100, where the ratio is the variance within a participant divided by the variance between participants, calculated separately for eight sex and country strata and pooled by weighting of each stratum specific estimate by n−1.
