Model 1 is our measurement model in which items were loaded onto their respective factors (i.e., perceived mastery climate, perceived performance climate, the need for autonomy, the need for competence, the need for relatedness, emotional exhaustion, and vigor). Model 2 is a six-factor model in which perceived mastery climate and perceived performance climate items were loaded onto one factor, and all other measures were loaded onto their respective factors. Model 3 is a six-factor model in which emotional exhaustion and vigor items were loaded onto one factor, and all other measures were loaded onto their respective factors. Model 4 is a five-factor model in which the need for autonomy, the need for competence, and the need for relatedness items were loaded onto one factor, and all other measures were loaded onto their respective factors. Model 5 is a four-factor model in which perceived mastery climate and perceived performance climate items were loaded onto one factor; the need for autonomy, the need for competence, and the need for relatedness items were loaded onto one factor, and all other measures were loaded onto their respective factors. Model 6 is a three-factor model in which perceived mastery climate and perceived performance climate items were loaded onto one factor; the need for autonomy, the need for competence, and the need for relatedness items were loaded onto one factor, and emotional exhaustion and vigor items were loaded onto one factor. Model 7 is a one-factor model in which all measure items were loaded onto one factor. Model 8 is our measurement model in which items were loaded onto their respective factors (i.e., perceived mastery climate, perceived performance climate, the need for autonomy, the need for competence, the need for relatedness, emotional exhaustion and vigor), and error terms were allowed to correlate if they pertained to the same latent factor. ***p < 0.001.
