Effects of repeated testing on the reliability of fitness scores of institutionalized mentally retarded individuals.
This study was designed to determine the effects of repeated trials on the reliability of physical fitness performance scores of 36, 12- to 20-year-old institutionalized mentally retarded children. They were tested 2 days a week for 5 consecutive weeks on the physical fitness criterion tests. The statistical analysis indicated no significant differences between trial scores on any variable over the 5 weeks. This lack of significance on all the physical fitness criterion tests suggests that administering all the trials on each item on one occasion is appropriate.
