Development of an efficient computerized adaptive test measuring children's self-care performance.
A 10-16 item computer quiz gives a rock-solid self-care score for any child.
01Research in Context
What this study did
Kuang et al. (2025) built a short computer test that asks parents about self-care. It is called CAT-SC-T.
Parents answer 10–16 items chosen by the computer. The test works for kids with and without disabilities.
What they found
Most kids got a reliability score of 0.95 or higher. That means the short test is very steady.
The test gives a strong picture of self-care with fewer questions than old paper forms.
How this fits with other research
Jones et al. (2007) showed a fixed 40-item autism screen could work. Kuang et al. (2025) goes further by letting the computer pick only the items each child needs.
Nah et al. (2019) cut a toddler autism tool to 5 items and kept 81 % accuracy. Kuang et al. (2025) matches that idea but uses smart item choice to reach 95 % reliability.
Bong et al. (2021) used a 10-minute caregiver talk plus play time. Kuang et al. (2025) shows you can get similar speed with just a parent quiz on a tablet.
Why it matters
You can now measure self-care in under five minutes. Use the CAT-SC-T at intake, before an IEP, or to check progress every few months. Less time testing means more time teaching skills like tooth brushing or shoe tying.

03Original abstract
BACKGROUND: The Computerized Adaptive Test for Measuring Children's Self-care Performance (CAT-SC) was developed with an interview administration approach for a limited population. AIMS: We developed a new CAT-SC (the CAT-SC-T) based on the original candidate item bank of the CAT-SC, using the caregiver-report approach and targeting children with and without disability. METHODS AND PROCEDURES DESIGN: In this cross-sectional study in the general community, 1289 caregivers of children with and without disability were assessed with the original candidate item bank of the CAT-SC. OUTCOMES AND RESULTS: The item bank of the CAT-SC-T contained 69 items with unidimensionality. The three stopping rules were (1) administering a minimum of 10 items and a maximum of 16 items, (2) observing the first 10 items receiving the lowest scores, and (3) ensuring a reliability of self-care performance estimate of 0.95. From the simulation analyses, only 10-16 items were needed for each assessment to achieve good reliability and validity. The person reliability for most children (83.9 %) exceeded 0.95. Of the 16.1 % not meeting the 0.95 reliability criterion, 19 % (n = 39) were extreme responders. The good concurrent validity of the CAT-SC-T was proven by its very high correlation coefficient (r = 0.99) between the scores using the entire item bank and the estimated scores of the CAT-SC-T. Significant score differences between children with and without disability indicated good discriminant validity. CONCLUSIONS AND IMPLICATIONS: The CAT-SC-T appears to be an efficient, reliable, and valid assessment of children's self-care performance. The CAT-SC-T can be applied to children with and without disability.
