Correlation and pathways of behavioral activation systems mediating physical activity level and depressive symptoms among college students

Figure 1 Flow chart of the participants recruitment.

Figure 2 Correlations among the variables. A: Depressive symptoms were significantly negatively correlated with physical activity; B: Depressive symptoms were significantly negatively correlated with reward responsiveness; C: Depressive symptoms were significantly negatively correlated with drive; D: Depressive symptoms were negatively, but not significantly, associated with fun-seeking; E: Physical activity was significantly positively correlated with reward responsiveness; F: Physical activity was significantly positively correlated with drive; G: Physical activity were positively, but not significantly, associated with fun-seeking.

Figure 3 Schematic diagram of the structural relationship model between physical activity, behavioral activation system, and depressive symptom indicators in college students with depressive symptoms. There are direct pathways and reward responsiveness-mediated indirect pathways between physical activity and depressive symptoms.
