摘要：Purpose. This study aims to verify the evidence of content, concurrent criterion validity, and reliability in a chassè checklist. Methods. First, 3 judges measured 11 items of the checklist based on the Likert scale, varying from 1 (not at all) to 5 (very much clear, pertinent, and representative), for the content evidence validity. In the second stage, 91 girls (12 ± 2.09 years old) were evaluated while performing the skill; 51 of them were skilled and 40 were novice in polka type chassè (concurrent evidence). Concerning reliability, 3 evaluators analysed the videos of 5 volunteers while performing polka type chassè at 2 different times, with an interval of 1 week between evaluations. Results. After the first stage, 1 item presented the content validity coefficient of 0.56 and it was reformulated as well as the skill was renamed to polka type chassè. The second assessment presented clear, pertinent, and representative items of the instrument. The reliability was considered appropriate by the inter-judge intraclass correlation coefficient (ICC) of 0.83 and the lowest intra-judge ICC of 0.80. Lastly, concurrent evidence was better when it came to skilled participants than novice ones related to polka type chassè. Conclusions. In general, the results indicated content and concurrent validity and reliability evidence. The instrument can be useful for physical education teachers as well as gymnastics coaches.
