METRIC CHARACTERISTICS OF THE TEST OF GROSS MOTOR DEVELOPMENT (TGMD 3)
The aim of this study was to determine metric characteristics of the Test of Gross Motor Development (TGMD 3). The study included 146 children from Bosnia and Herzegovina, aged 3-10,4 (6,80 ± 2,23 years; 46,6% male; 53,4% females). Based on the obtained research results it can be concluded that Test of Gross Motor Development (TGMD-3) has satisfactory reliability and internal consistency for children aged 3 to 10 years. Mutual correlations confirm the homogenity of the scale. Based on results of Kolmogorov-Smirnov test, Test of Gross Motor Development is not sensitive for subjects included in this study. The obtained results of the confirmatory factor analysis of this model show a partial agreement of the assumed model with the data ( h2 = 108.17, df = 64, h2 / df = 1.69, TLI = 0.86, CFI = 0.72, NFI = 0.72., RMSEA = 0.07 CI = 0.04-0.09). The data was analyzed with the SPSS 20 software (with the AMOS package). The limitations in the research are the respondents, because due to the epidemiological situation caused by COVID 19, a convenience sample of respondents was selected. Key words: Motor development, TGMD 3, childhood, reliability, confirmatory factor analysis.
