Reliability and validity of a motor skill test in young adults

Abstract

Purpose: To study the validity and reliability of an assessment battery for basic motor skills called "Romero Test Battery" (BRT).Methods: A total of 1003 young and active adults (22±2.5 years old) were included in the sample. To study the validity and reliability of the BRT, the Cronbach's alpha statistic was used to assess internal consistency. Additionally, the degree of inter-rater agreement was investigated using the intraclass correlation coefficient (ICC). To determine the psychometric validity of the battery, the construct validity was examined by comparing the results of the BRT between athletes and non-athletes.Results: The internal consistency of the battery was deemed acceptable (Cronbach's alpha value = 0.69). The agreement among the evaluators was very good, with an ICC of 0.977. For construct validity, the arithmetic means were compared using the Mann-Whitney U test, which demonstrated that the BRT was able to discern a significant difference in basic motor skills between athlete and non-athlete participants. Conclusions: The BRT proved to be a tool with reliable attributes and sufficient validity
