Comparing the psychometric properties of the pediatric outcomes data collection instrument and the Activities Scales for Kids: A review
2014-08-22 12:20
Abstract
The aim of this study was to review and evaluate the psychometric properties of two general
musculoskeletal outcome measures focusing on pediatric physical disability, namely, the Pediatric
Outcomes Data Collection Instrument (PODCI) and the Activities Scales for Kids (ASK). Although
this review reveals the psychometric superiority of ASK to PODCI, further research should
confirm the psychometric properties of both the instruments. A number of psychometric issues
need to be further addressed. Specifically, future studies should examine additional types of
reliability and validity, for example, content, construct, criterion, and discriminant with more
sophisticated statistical analyses, for example, Aiken’s item content validity coefficient and
confirmatory factor analysis. Until these issues are addressed, researchers should be cautious
utilizing these instruments in children with musculoskeletal problems in a clinical setting.
