Measurement instruments to understand self-determined motivation towards physical activity among college students with intellectual disabilities are needed to develop programs to support physical and psychological health and well-being. The purpose of the current study was to validate a modified questionnaire measuring basic psychological needs towards physical activity among college students with intellectual disabilities.
A total of 108 college students with intellectual disabilities completed the modified questionnaire. Validity and reliability of the questionnaire was examined.
Confirmatory factor analysis demonstrated a six-factor model had good model fit. Cronbach's alpha values showed acceptable reliability evidence of the instrument as a whole, although some alpha values in subdomains of the instrument were below acceptable values.
The modified questionnaire was found to have acceptable validity evidence. Further studies are needed with refinement of answer options and the addition of more questions to increase reliability.
需要测量工具来了解智障大学生对体育活动的自主动机，以便制定支持身体和心理健康的计划。本研究的目的是验证一种经过修改的问卷，用于测量智障大学生对体育活动的基本心理需求。
共有 108 名智障大学生完成了修改后的问卷。检验了问卷的有效性和可靠性。
验证性因素分析表明，六因素模型具有良好的模型拟合度。克朗巴赫的α值表明，该工具作为一个整体具有可接受的可靠性证据，尽管工具的一些子领域的α值低于可接受值。
修改后的问卷具有可接受的有效性证据。需要进一步研究，改进答案选项，并增加更多问题以提高可靠性。
