Aim To evaluate the interrater reliability of the inclusion in registries and
classification of children with cerebral palsy (CP). Method Two studies were
conducted. In study 1, 12 paediatricians from 11 countries viewed video sequences
of 12 children with or without CP (nine males, three females; median age 6y;
range 2-16). In study 2, 19 professionals from eight countries participated in an
online exercise. They had to classify the same children but based on written
vignettes. All participants had to evaluate whether the child had CP, the
neurological subtype (Surveillance of Cerebral Palsy in Europe classification
system), and gross motor function level (Gross Motor Function Classification
System [GMFCS]). Kappa (kappa) coefficients were calculated for categorical
variables and intraclass correlation coefficients (ICCs) for ordinal data.
Results Reliability was excellent in assessing whether or not a child had CP in
study 1 (kappa=1.00) and substantial in study 2 (kappa=0.73); 95% confidence
interval [CI] 0.58-0.87). For the neurological subtype, overall kappa between
paediatricians was 0.85 (95% CI 0.68-0.98), with full agreement observed for
eight children. In study 2, overall kappa was 0.78 (95% CI 0.61-0.91) with full
agreement seen for five children. For the GMFCS, the ICC was 0.88 (95% CI
0.78-0.95) in study 1 and 0.80 (95% CI 0.64-0.91) in study 2. Interpretation
Reliability was excellent for all characteristics classified by paediatricians
viewing the videos and substantial for professionals reading vignettes.
