Note.

N = 157

Samples sizes range from 129 to 157 across analyses due to missing data. Dash indicates that the analysis was not performed either because it was not relevant or because there was no association between TPI-R and the PA-related behavior outcome. Indirect effect = mediational effect of TPI-R on IPAQ outcome through PAES-Reward. Direct effect = effect of TPI-R on IPAQ outcome after adjusting for PAES-Reward. PA = Physical Activity. PAES = Physical Activity Enjoyment Scale. TPI-R = Tripartite Pleasure Inventory-Responsiveness Subscale. CESD = Center for Epidemiologic Studies Depression Scale.

^aUnadjusted standardized regression parameter

^bAdjusted standardized regression parameter after controlling for gender and CESD score.
