Table_1_Identifying the Validity and Reliability of a Self-Report Motivation Instrument for Health-Promoting Lifestyles Among Emerging Adults.docx

Objective: Studies on the effectiveness of health-promoting programs across educational contexts need a new tool for measuring health motivation. This study aims to develop a new health motivation questionnaire, namely the College Students’ Health Motivation Questionnaire (CSHM-Q), for college students.Design: An original item pool of the CSHM-Q was developed based on a systematic synthesis and review of related instruments and the content analysis of focus group interviews (N = 93). The instrument was then validated using a sample of 205 college students.Setting: Interviews and survey were conducted at three universities in China.Methods: This study explores the content validity, construct validity, and reliability of a self-report motivation instrument based on the framework of Self-Determination Theory.Results: A pilot study showed satisfactory content validity of the motivation constructs and produced 40 items for the CSHM-Q. Results of exploratory factor analysis and parallel analysis further substantiated a three-factor structure of the CSHM-Q. The finalized three-component CSHM-Q has 16 items.Conclusion: Given adequate psychometric properties, the CSHM-Q is a promising measurement tool of health motivation for practical and research purposes.

研究目标：鉴于探讨促进健康项目在教育环境中有效性所需的测量健康动机的新工具，本研究旨在开发一套针对大学生的新型健康动机问卷，即大学生健康动机问卷（CSHM-Q）。设计：CSHM-Q的原型项目库是基于对相关工具的系统综合与评鉴以及焦点小组访谈（N = 93）的内容分析而构建。随后，该工具使用205名大学生的样本进行了验证。研究背景：在中国三所大学进行了访谈和问卷调查。研究方法：本研究基于自我决定理论框架，探讨了一项自我报告动机工具的内容效度、结构效度和可靠性。研究结果：一项预研究显示，动机结构的内容效度令人满意，并为CSHM-Q产生了40个项目。探索性因素分析和平行分析进一步证实了CSHM-Q的三因素结构。最终确定的CSHM-Q由16个项目组成。研究结论：鉴于其充分的心理学特性，CSHM-Q有望成为实践和研究目的下测量健康动机的有前景的工具。
