Abstract
The aim of the current research was to evaluate the psychometric properties aspects (validity and reliability) of the Body Coordination Test for Children (KTK) among children of Tehran city. The strategy and design of the research were descriptive and cross-sectional, respectively. Three hundred and eight children aged 5-14 years old (0/61 male) chosen from five main districts of the city using cluster sampling. Our research tool was the Body Coordination Test for Children (KTK). The confirmatory Factor analysis by using structural equation modeling (SEM), content, face and divergent validity, internal consistency, intra- inter-class and Pearson correlation coefficients and construct reliability statistical methods were used. Content Validity Index with final value of (0.91) was obtained. The internal consistency for the total KTK was) α=0.84) and shows in a range of (0.61 to 0.97) for four subscales with 10 age bands. In addition, the reliability of test-retest for the total KTK was (r= 0.95). The intra and inter-rater reliability coefficient the sum of subscales was 0.98, 0.97 respectively. In order to evaluate the construct validity, Kiphard’s one-factor design was confirmed using Confirmatory factor analysis. Correlation coefficients of the subtests were significant and positive with age. Finally, the values of construct reliability and divergent validity were (0.87) and (0.63), respectively. Considering the confirmation of the validity and reliability of the KTK, it can be used to evaluate the body coordination of children aged (5-14) in Tehran.
