背景:本研究旨在开发针对中国大学生的体育锻炼触发因素问卷,并评估其信度和效度。
方法:在福格行为模型和半公开访谈的理论基础上,编制了一份包含18个项目的初始问卷。最初的问卷是对575名学生进行的,并检验其信度和效度,项目判别分析,相关分析,同质性测试,采用SPSS26.0进行探索性因素分析。在对初始问卷进行审查后,最初的18个项目减少到14个。对621名大学生进行了14项问卷,有了数据,相关分析,验证性因素分析,效度检验,并进行了可靠性测试。
结果:为了检查18个项目的心理测量特性,进行探索性因素分析和验证性因素分析,并对其信度和效度进行了检验。在第一轮项目开发分析之后,四个项目被删除,并开发了包含14个项目的触发因素问卷。这14个项目有三个维度,包括火花,信号,和促进者触发器,三个维度的累积解释方差为61.21%。对14个项目三个维度的验证性因子分析表明了合适的尺度拟合指数。内部一致性可靠性,半分割可靠性,14个项目的重测信度分别为0.925、0.821和0.860,表明项目具有适当的可靠性。
结论:本研究的身体活动触发问卷具有可接受的信度和效度。这是第一个测量中国大学生身体活动触发因素的问卷,将为理解身体活动触发因素的心理测量特性提供新的依据。此外,从开发的触发因素问卷中收集的未来发现可用于制定促进大学生健康的策略。
BACKGROUND: This study aimed to develop a Physical Activity
Triggers Questionnaire for Chinese college students and to evaluate its reliability and validity.
METHODS: On the theoretical basis of the Fogg behavior model and semi-open interviews, an initial questionnaire with 18 items was compiled. The initial questionnaire was administered to 575 students, and to examine its reliability and validity, item discrimination analysis, correlation analysis, homogeneity test, and exploratory factor analysis were conducted using SPSS 26.0. After the examination of the initial questionnaire, the initial 18 items were reduced to 14. The 14-item questionnaire was administered to 621 college students, and with the data, correlation analysis, confirmatory factor analysis, validity test, and reliability test were conducted.
RESULTS: To examine the psychometric properties of the 18 items, exploratory factor analysis and confirmatory factor analysis were conducted, and their reliability and validity were examined. After the first round of item development analysis, four items were removed, and a
triggers questionnaire with 14 items was developed. The 14 items had three dimensions, including spark, signal, and facilitator
triggers, and the cumulative explained variance of the three dimensions was 61.21%. The confirmatory factor analysis of the three dimensions of the 14 items indicated appropriate scale fit indices. The internal consistency reliability, split-half reliability, and test-retest reliability of the 14 items were 0.925, 0.821, and 0.860, respectively, showing that the items have appropriate reliability.
CONCLUSIONS: The Physical Activity Triggers Questionnaire of the study has acceptable reliability and validity. It is the first questionnaire to measure Chinese college students\'
triggers of physical activity and will provide a new basis for the understanding of psychometric properties of physical activity
triggers. In addition, the future findings collected from the developed triggers questionnaire can be used to develop strategies to promote health among college students.
