The psychometric of the Pictorial Scale of Perceived Movement Skill Competence in 7-10 Years Old Children Ahvaz city.

A child's perception of her/his motor competence can play an important mediating role between actual motor competence and physical activity. The aim of this study was to translate into Persian and evaluate the validity and reliability of the Pictorial Scale of Perceived Movement Skill Competence (PMSC ) in 7-10 Years Old Children Ahvaz. The research strategy and design were descriptive-normative and cross-sectional rrespectively. A total of 256 children aged 7-10 years were selected and evaluated by cluster sampling from different regions of Ahvaz. One week later, one subset (n=98) was randomly selected to determine face validity and another subset (n=87) was selected to determine the reliability of test-retest. The research tool was PMSC test. Descriptive statistical methods and confirmatory factor analysis, intra-class correlation coefficient and Cronbach's alpha were used. Face validity was better for object control skills. Cronbach's alpha Results were acceptable in both subtests and the whole test (0.74 to 0.94). Intra-class correlation was high for locomotor subtest (0.90), object control subtest (0.91) and total test (0.94). The hypothesized two-factor model was tested and confirmed. Fit indices had acceptable values. Considering the confirmation of the validity and reliability of PMSC , it can be used with confidence to assess the perceived competence of Ahwaz children's motor skills. Since the samples were only from children in Ahvaz, the results may not be generalizable for all children in Iran. Future studies should evaluate the characteristics of test based on the cultural diversity of other regions.
