• Resumen

  • Purpose: To verify a protocol's content validation and reliability for assessing the precision in the throw of Paralympic boccia in two different steps. Methods: The study was divided into two steps: In step 1, the perception of 15 boccia coaches was evaluated using a questionnaire containing 6 questions about the pertinence of the protocol on a Likert scale (1 to 5). In step 2, reliability was evaluated by two researchers, applying the protocol with two targets (0.5 and 1.0, targets) to verify the short precision (SP), average precision (AP), long precision (LP), and total precision (TP) of 23 boccia athletes (BC1 = 5; BC2 = 7; BC3 = 1; BC4 = 10) in tournaments of the modality. The Content Validity Index (CVI) calculation was applied for the electronic questionnaire, the Intraclass Correlation Coefficient (ICC) for the agreement between evaluators, and the T-Test for the difference between means. p < .05 was adopted. Results: In the result of the CVI, reliability was noticed through the experts' evaluation (Question1 = 1.0; Q2 = 0.93; Q3 = 0.80; Q4 = 0.80; Q5 = 0.93; Q6 = 0.93). There was an agreement between the evaluators by the ICC in the 0.5 targets for SP (p < .01), AP (p < .01), LP (p < .01), and TP (p < .01), and in the 1.0 target for SP (p < .01), AP (p < .01), LP (p < .01), and TP (p < .01). No differences were found between the means in the t-test. Conclusion: It was demonstrated that the protocol meets the established reliability and content validity criteria, allowing its practical use to evaluate the precision in the boccia.
