| Popis: | The purpose of this study was to (1) investigate the construct validity and (2) test-retest reliability of the Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (PEDI-CAT) in children with cerebral palsy (CP).A prospective convenience cross-sectional sample.Multidisciplinary CP clinic in a tertiary level pediatric children's hospital.English- and Spanish-speaking school-aged children (N=101) with a diagnosis of CP, stratified by Gross Motor Function Classification System level, who presented to our multidisciplinary clinic. Participants were excluded if they underwent recent surgery (6mo) or botulinum neurotoxin A injection (3mo). A subset of 17 families participated in retest reliability.Convergent and divergent validity were evaluated using Spearman correlation coefficient analysis; test-retest reliability was assessed using intraclass correlation coefficients (ICCs).Mean age was 12±3.7 years. Convergent validity was established between Mobility (PEDI-CAT) and Functional Mobility Scale (FMS) (5 m, r=0.85; 50 m, r=0.84; 500 m, r=0.76; P.001). In ambulant children, convergent validity was established between Daily Activities (PEDI-CAT vs Pediatric Quality of Life CP [PedsQL-CP] [r=0.85, P.001]) and between Social/Cognitive (PEDI-CAT) and Speech and Communication (PedsQL-CP) (r=0.42, P.001). In nonambulant children, convergent validity was established between Daily Activities (PEDI-CAT) and Personal Care (Caregiver Priorities and Child Health Index of Life with Disabilities [CPCHILD]) (r=0.44, P.001) and between social/cognitive (PEDI-CAT) and Communication (CPCHILD) (r=0.64, P.001). A lack of correlation between Daily Activities, Social/Cognitive, and Responsibility (PEDI-CAT) and FMS and between the Mobility (PEDI-CAT) and Communication (PedsQL) domains confirmed divergent validity. Test-retest reliability was excellent for all domains of the PEDI-CAT (ICC=0.96-0.99).The PEDI-CAT is an outcome measure that demonstrates strong construct validity and reliability in children with CP. |
