Structural Validity of the Test of Gross Motor Development-2

Article excerpt

The proficiency of gross motor skills in early years is a foundation to the introduction of physical fitness and the development of more advanced and specific movement skills in later life (Bouchard, McPherson, & Taylor, 1992; Gallahue & Ozmun, 1998). Therefore, a valid movement skill assessment tool is essential. It not only serves as a device for detecting developmental delays but also permits the collection of valuable data that can facilitate program planning. One of the frequently used movement skill assessments was the second edition of Test of Gross Motor Development (TGMD-2; Ulrich, 2000). It was a process-oriented assessment provided with criterion- and norm-referenced interpretations. Although the TGMD-2 was validated on U.S. children, information regarding its reliability and validity was limited. Further, more analyses were needed to examine the structural validity of this testing instrument in countries other than U.S. The purpose of this study was to examine the factor structure of the TGMD-2 as applied to Chinese children. The TGMD-2 was administered to 1251 Hong Kong Chinese children (N = 1251) by a research team, which consisted of one investigator and four testers. After data screening, a total of 1,228 cases (N = 1228) were used for further analysis. The data set was randomly split into two halves: one for exploratory factor analysis (EFA; n = 614) and the other for confirmatory factor analysis (CFA; n = 614). …
