OBJECTIVE. The aim of this paper was to check on the reliability of the Movement Assessment Battery for Children (Movement ABC) in preparation for its standardization in Hong Kong. Interrater and test–retest reliability are reported for Age Band One, designed for use with children ages four to six.
METHOD. Interrater reliability of the Movement ABC was estimated using two trained observers with 79 children. Test–retest reliability was assessed using 75 children who were tested twice by the same tester over a 2- to 3-week interval.
RESULTS. Agreement between testers was good with a mean intraclass correlation of 0.96 across items. A value of 0.77 was obtained for test–retest reliability.
CONCLUSION. These results support the use of this component of the Movement ABC in Hong Kong.
