Test-retest reliability of the self-assessed physical activity checklist.
To estimate the test-retest reliability of a modified version of the Self-assessed Physical Activity Checklist two administrations separated by 5 days were conducted for 52 boys and 51 girls in Grade 6 in Australia. Intraclass correlation coefficients were calculated to assess the reliability. Similar test-retest reliabilities were found between boys and girls for light, moderate, and total physical activity, with the largest difference for vigorous physical activity (.44 vs .12). The results suggest that the checklist is a more appropriate measure of boys' physical and sedentary activity as boys reported higher reliability coefficients on all categories except for light physical activity and TV/Video watching.
