Self-determination, behavioral engagement, disaffection, and academic performance: A mediational analysis

Abstract

The present study examined the role of behavioral engagement and disaffection as mediators between self-determination and academic performance. Participants were 545 secondary students (53.4% girls) aged 12 to 19 years. Variables were assessed in the Spanish language classroom over a nine-month period. Students estimated their self-determination, and their teachers assessed student engagement, disaffection, and performance. Structural equation models corroborated the hypotheses: the types of self-determination differentially predicted engagement (R 2 =.39) and disaffection (R 2 =.24), and were progressively more adaptive the higher the autonomy; self-determination, behavioral engagement, and disaffection predicted performance (R 2 =.43); engagement and disaffection partially mediated the relationship from external regulation (β = -.097; p
