Abstract
The aim of this research was validating Persian translated version of "Perceived Physical Ability Scale for Children". Samples were 384 boys' students from grades 3 to 5 in Arak's elementary schools. From 1 and 2 districts of education office in Arak city 384 subjects from 3 to 5 grades selected cluster randomely and data were selected by "Perceived Physical Ability Scale for Children". Confirmatory factor analysis with principle components used to determine structure validity and Varimax Rotation for identifying factor structure. Bartle's test used for data sphercity and CMO for samples adequacy. Convergent validity and test-retest reliability calculated with Pearson Correlation Coefficient and internal reliability with Chronbach’s alpha. The results of Confirmatory factor analysis with principal components and Varimax rotation for determining factor structure resulted in identifying only one factor extraction. Test-retest and internal reliability were 0.81 and 0.76, respectively. Correlation coefficient of scores of "Perceived Physical Ability Scale for Children" with scores of modified pull-up, seat-up, flexibility, 45-m running and 4×9 agility were between 0.31 to 0.54.The research results confirm validity and reliability of the scale for students in grades 3-5 of elementary schools. The scale can be used for research, educational and sport purposes.
