The aim of this study was to determine the agreement and reliability of
parent report using a lay version of the Gross Motor Function Classification
System (GMFCS) among children with cerebral palsy in the two youngest age bands.
METHOD: Data were obtained from the Canadian section of the Movement and
Participation in Life Activities of Young Children study database. One hundred
and thirty-two parents of two groups of children participated: children aged 2 to
4 years (35 males, 26 females; mean age 3y 2mo; SD 5mo) and children aged 4 to 6
years (39 males, 32 females; mean age 4y 11mo; SD 6mo) at the final data
collection point. Therapists classified motor function using the GMFCS and
parents used the GMFCS Family Report Questionnaire, with parents and therapists
being masked to the others' responses. Agreement between respondents was
determined using precise agreement and Cohen's unweighted kappa statistic.
Reliability between respondents was determined using the intraclass correlation
coefficient (ICC). RESULTS: Overall, precise agreement was 77%, chance-corrected
agreement was kappa = 0.70 (95% confidence interval [CI] 0.61-0.79), and
reliability was ICC = 0.95 (95% CI 0.93-0.96). Interpretation: These values
indicate substantial agreement and reliability between parents of children aged 2
to 6 years and therapists. Some parents had a tendency to rate their children as
more functionally limited than did therapists, leading us to question whose the
true criterion standard' rating should be.
