Perceived Autonomy Support from Peers, Parents, and Physical Education Teachers as Predictors of Physical Activity and Health-Related Quality of Life among Adolescents—A One-Year Longitudinal Study

Abstract

The current research adopts the trans-contextual model of motivation (TCM) to examine the role of perceived autonomy support from peers, parents, and physical education (PE) teachers on adolescents’ autonomous motivation, intentions, and physical activity (PA) and health-related quality of life (HRQoL) over a one-year period. Adolescents (N = 264) aged between 11 and 15 years (M = 13.24; SD = 0.96) filled in relevant questionnaires during a four-wave longitudinal study. Perceived autonomy support from peers, parents, and PE teachers predicted PA (β ≥ 0.03, p p p p p p = 0.52). The unidirectional cross-lagged relationship with the flow from PA to later HRQoL suggests that intervention programs focusing on promoting PA behaviour in adolescents should produce the most pronounced effects if their aim is also to promote HRQoL.
