大学生专业内部动机与主观幸福感的关系:专业投入与主观专业成就的中介作用

自我决定理论认为，内部动机是主观幸福感的重要影响因素。为了探究大学生专业内部动机与主观幸福感的内部机制，研究者使用专业内部动机问卷、专业投入问卷、主观专业成就问卷、主观幸福感问卷对3527名在校大学生进行了调查。研究结果表明：（1）专业内部动机正向预测主观幸福感；（2）专业投入在专业内部动机与主观幸福感之间起中介作用；（3） 主观专业成就在专业内部动机与主观幸福感之间起中介作用；（4）专业投入和主观专业成就在专业内部动机和主观幸福感之间起链式中介效应。据此得出结论：专业投入和主观专业成就在专业内部动机和主观幸福感之间起链式中介效应。

The Relationship between College Students' Major Intrinsic Motivation and Subjective Well-being: The Mediators of Major Engagement and Subjective Major Achievement

Self-determination theory suggested that intrinsic motivation is an important factor of subjective well-being. In order to explore the internal mechanism of internal motivation and subjective well-being, the researchers investigated 3,527 college students by using Major Intrinsic Motivation Scale, Major Engagement Scale, Subjective Major Achievement Scale and Subjective Well-being Scale. The research found that: (1) major intrinsic motivation positively predicted subjective well-being; (2) major engagement played a mediating role between major intrinsic motivation and subjective well-being; (3) subjective major achievement played a mediating role in the relationship between major intrinsic motivation and subjective well-being; (4) major engagement and subjective major achievement played a serial mediating role between major intrinsic motivation and subjective well-being. Overall, major engagement and subjective major achievement play a serial mediating role in the relationship between college students’ major intrinsic motivation and subjective well-being.
