ABSTRACT

Objective : We compared the Gross Motor Function Measure(GMFM) and the Bayley Scale of Infant Development-second edition(BSID-Ⅱ) to investigate the applicability of GMFM in evaluating infants with developmental disabilities except cerebral palsy.Methods : Subjects were 26 infants with a mean corrected age of 16.26(SD=8.17). Subjects divided into subgroups by gestational age, birth weight, corrected age. The GMFM and BSID-Ⅱ were administered to the total infants. Statistical analysis was done by Mann-Whitney U test and Spearman’s correlation, using SPSS-PC(version 10.0).Results : There were not statistically significant for the comparison of the GMFM percentage scores with the BSID-Ⅱ raw scores in subgroups expect corrected age group. The correlation coefficients of GMFM scores and BSID-Ⅱ mental scale were ranged between 0.63 and 0.72, those of GMFM scores and BSID-Ⅱ motor scale were ranged between 0.57 and 0.90 in subgroups. The average correlation coefficients of GMFM scores and BSID-Ⅱ mental scale were 0.71, those of GMFM scores and BSID-Ⅱ motor scale were 0.84 in total subjects.Conclusion : The findings suggest that the GMFM and BSID-Ⅱ are valuable in evaluating infants with developmental delays. Implications for selection and use of either measures are discussed.
