The relationship between physical activity and depression in college students: the chain mediating role of mindfulness and meaning in life

In order to explore the chain mediating effect of mindfulness and meaning in life between physical exercise and depression, 954 college students were investigated by physical exercise rating scale, self-rating depression questionnaire, mindfulness scale and meaning in life questionnaire. The results show that: (1) Physical exercise can significantly positively predict mindfulness and meaning in life, and significantly negatively predict depression; (2) The direct effect of physical exercise on depression of college students is not significant, but the indirect effect is significant. It can significantly predict depression of college students through the independent mediating effect of mindfulness and meaning in life, and can also significantly predict depression of college students through the chain mediating effect of mindfulness and meaning in life.
