ABSTRACT

Objective: This study aims to determine the validity and reliability of Movement ABC-2. Methods: The study included a total of 87 people who met the inclusion criteria. Prior to validation of validity and reliability, translation of Movement ABC-2 was carried out. Validation of validity and reliability was carried out simultaneously with content validity, discriminant validity, internal consistency and test-retest reliability. Results: Content validity index resulted in 0.93, and concurrent validity resulted in a positive correlation of 0.795, comparing the correlation between BOT-2 short form and percentiles. Correlation between domain with BOT-2 has shown significant correlation between domain with similar challenges in aiming & catching and balance. As a result of comparing gender and age differences, all items showed significant differences in gender, and significant differences were identified in age differences except 'jumping on the mat'. The internal consistency of Cronbach's α was 0.577 and the test-retest reliability was 0.766. Conclusion: Movement ABC-2 has been verified as a valid assessment tool for Korean children and is a reliable tool for use by Korean therapists and clinicians. This is expected to result in various uses of Movement ABC-2.
