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.

Is there anything else that is important to you that we didn’t get to talk about? Would you like to tell me? (Keller et al., 2006).
