ABSTRACT=<p><bold>Objective:</bold> 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.</p><p><bold>Design:</bold> 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 (<italic>N</italic> = 93). The instrument was then validated using a sample of 205 college students.</p><p><bold>Setting:</bold> Interviews and survey were conducted at three universities in China.</p><p><bold>Methods:</bold> This study explores the content validity, construct validity, and reliability of a self-report motivation instrument based on the framework of Self-Determination Theory.</p><p><bold>Results:</bold> 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.</p><p><bold>Conclusion:</bold> Given adequate psychometric properties, the CSHM-Q is a promising measurement tool of health motivation for practical and research purposes.</p>
