Construction and content validity of the coaches’ knowledge and competence questionnaire - CKCQ

Abstract The validation of this questionnaire is an important tool for analyzing theknowledge and skills of coaches, as well as a better understanding of their practice context. Therefore, the aim of the present study was to establish the content validity of the Coaches’ Knowledge and Competence Questionnaire (CKCQ). Five specialists with doctorate degree for at least 10 years, academic experience and periodicity of publications with the theme in national and international journals participated in the validation process. Specialists evaluated 38 items of the questionnaire and assigned a score on a 1-5 point likert scale for each item in the language clarity, practical pertinence and theoretical relevance criteria. The content validity coefficient (CVC) was used to determine the CVCI of items and the CVCt of the total instrument of each criterion, adopting cutoff point of 0.81. The approximate results found for language clarity (0.92), practical pertinence (0.99) and theoretical relevance (0.98) presented values considered almost perfect and appropriate for validation. The content validation of the CKCQ is an important alternative for the evaluation of the knowledge and competences of sports coaches.摘要：本问卷的效度检验是分析教练员知识与技能、深入了解其执教实践场景的重要工具。因此，本研究旨在确立《教练员知识与能力问卷》（Coaches’ Knowledge and Competence Questionnaire, CKCQ）的内容效度。本次效度检验共邀请5名专家参与，他们均拥有至少10年博士学历、具备相关学术经验且定期在国内外期刊发表该主题研究成果。专家们对问卷的38个条目进行评估，针对每个条目，从语言清晰度、实践针对性与理论相关性三个维度，采用1-5分李克特（Likert）量表进行打分。本研究采用内容效度系数（Content Validity Coefficient, CVC），针对三个评估维度分别计算各条目的内容效度系数（CVCI）与问卷整体的内容效度系数（CVCt），并设定0.81为临界判定值。本次检验得到的语言清晰度、实践针对性与理论相关性维度的得分分别为0.92、0.99与0.98，均处于近乎完美的水平，符合效度检验的合格要求。综上，《教练员知识与能力问卷》的内容效度检验，可为体育教练员的知识与能力评估提供重要的可行方案。
