Content validation and inter-rater reliability of a protocol for the precision assessment of boccia players

Abstract

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
