CONTENT VALIDITY, RELIABILITY AND CONSTRUCT VALIDITY OF A CHECKLIST FOR DIVE ROLL EVALUATION
ABSTRACT The objective of this study was to verify the content validity, reliability and construct validity of a checklist for dive roll evaluation. As for content validity, 4 experts in the Artistic Gymnastics field evaluated the checklist using the Delphi technique. Results showed good content validity indexes for the evaluation questions (CVI>0.80). About reliability, 6 raters analyzed 20 dive roll videos of 10 children, using the checklist. Results showed intra-rater ((ICC>0.80) and inter-rater agreement (ICC>0.90). Finally, concerning construct validity, 156 skill videos were analyzed using the checklist. Cronbach’s alpha and Exploratory Factor Analysis with Varimax rotation were applied, with the latter indicating good internal consistency (α=0.76) and the existence of three factors that explain the checklist. Thus, it is concluded that the checklist is valid and reliable to evaluate the proposed motor skill.
