Design and validity of an instrument - run cross hopping throw and catch (rcht&c) test for assessing motor competence in athletics

The aim of this study was to design and validate a tool for assessing motor competence (MC) and detecting talent in children aged between 6 and 10 years in athletics. Ten experts were carefully selected to collaborate in the validation. Cronbach's alpha and intraclass correlation coefficient (ICC) were used, respectively, to check for construct's validity and to reliability. Lin's Concordance Correlation Coefficient (CCC) was calculated as a complementary test. Additionally, the Aiken's V value was used to validate the tool. ICC (0.855) and Cronbach's alpha (0.922) showed acceptable reliability and consistency, respectively, and Lin's CCC (0.786) indicated excellent reproducibility, thus proving stability and consistency over a two-week period. Aiken's V value was 0.92, confirming the validity of the test. By parameter, univocity had Aiken's V of 0.92, relevance of 0.91, and importance of 0.91. Therefore, we conclude that this tool can be a valid test for assessing MC in athletics. Keywords: Validation, Instrument, Motor Competence, Talent, Children and Athletics
