Factorial Structure Validation of the Movement Assessment Battery for Children in School-Age Children Between 8 and 10 Years Old

Abstract

Abstract: The adaptation of instruments to other cultural contexts is a complex task that requires careful planning to maintain the content and psychometric properties. One of the most used motor assessment tools in the world is the Movement Assessment Battery for Children 2ed. In this study, we evaluated the factorial organization of the MABC-2 for the age group 8-10 years from the perspective of classical and modern psychometric theory. For this purpose, a group of 350 school children in the city of Manaus (AM, Brazil) was evaluated. The factorial structure of the MABC-2 and a new factorial structure with four factors were tested. For data analysis, descriptive and inferential statistics were used. Factor analysis confirmed the original three-factor model. Based on these results, good evidences of validity were produced, based on the internal structure of the MABC-2 proposed by the original authors, confirming its ability to identify disorders in the development of coordination.
