Confirmatory factor analysis of the test of gross motor development-2

The purpose of this study was to examine the underlying structure of the second edition of the Test of Gross Motor Development-2 (Ulrich, 2000) as applied to Chinese children. The Test of Gross Motor Development-2 was administered to 626 Hong Kong Chinese children. The outlier test with standard scoring was utilized. After data screening, a total of 614 cases (N = 614) were used for further analysis. The two-factor structure of the Test of Gross Motor Development-2 was tested using confirmatory factor analysis with maximum likelihood estimation to compute parameter estimates and to select the appropriate item for each factor. The goodness-of-fit indices supported that the model was tenable (goodness-of-fit index =.95, root mean square error of approximation =.06, standardized root mean square residual =.04, comparative-fit index =.97). The findings of this study suggested that the two-factor structure proposed by Ulrich (2000) fit the data of Hong Kong Chinese children.
