Abstract

Objective : This study aimed to verify the construct validity of the Korean version of the Peabody Developmental Motor Scale-2 (K-PDMS-2) and its test-retest reliability for children with cerebral palsy (CP) and typical children.
Method : To ascertain the construct validity, the K-PDMS-2 evaluation was conducted on 42 children with cerebral palsy and 42 typical children of similar age and gender. Construct validity was proved through comparison with standard scores. Ten of the children with CP were re-evaluated after two weeks to determine test-retest reliability.
Results : There was a statistically significant difference in gross motor and fine motor development according to five subtests between the group of children with CP and the typical group (p = .000). For test-retest reliability, the correlation coefficient of the total frequency score was .989, representing very high temporal stability.
Conclusion : This study confirmed that K-PDMS-2 is an evaluation tool of high reliability and validity, and a potentially useful future measure for domestic clinical sites and research.
