Situational and Dispositional Factors that Predict Motivation: a Multilevel Study por Pineda Espejel, Heriberto Antonio, López Walle, Jeanette M., Tomás, Inés

“…Task orientation positively predicts the autonomous motivation (γ10 =.51, p < .01), and inversely the non motivation (γ10 = –.76, p < .001). Also task orientation partially mediated the relationship between task-involving climate and autonomous motivation (b1b2 = .39; 95% CI = [.11, .68]; τ = .68, p < .05), and fully mediated the relationship between task-involving climate and amotivation (b1b2 = –.58; 95% CI = [–.92, –.25]; τ = –.62, p >.05). …”
