title: Test-Retest Reliability of the Child Occupational Self-Assessment (COSA).
abstract: We examined the test-retest reliability of the Child Occupational Self-Assessment (COSA). Fifty-two children ages 6-12 yr completed the COSA on two separate occasions 7-14 days apart. Participant data were analyzed using intraclass correlation coefficients (ICCs). Test-retest reliability was good for total Competence and Value scores (ICC2,1=.72-.77) and poor to good across category scores (ICC2,1=.44-.78). These findings suggest that the children's perceptions of their abilities and the value they placed on their everyday activities as reflected in the test items were fairly consistent over a short period of time.
