Motivation for physical activity in young adults with physical disabilities during a rehabilitation stay: A longitudinal test of self-determination theory

摘要

We tested a self-determination theory (SDT) process model during a 3 week physical activity rehabilitation stay among young adults with a physical disability (N=44, M_(age)=24.7, SD=5.1). As hypothesized, perceived autonomy support positively predicted needs satisfaction at the end of the stay (r=38, p<.01). Further, needs satisfaction was positively linked to changes in autonomous motivation for physical activity (r=47, p<.01). Both changes in autonomous motivation and self-efficacy were associated with physical activity increases over the stay (r=57, p<.01 and r=47, p<.01, respectively). Bootstrapping results supported the SDT process model, indicating a support for a development toward more self-determined motivation in rehabilitation.
