Two Randomized Controlled Trials to Help Teachers Develop Physical Education Students' Course-Specific Grit-Perseverance and Mental Toughness

초록

Adopting both a self-determination theory perspective and a proactive, asset-oriented approach to coping with stressors, we propose a hypothesized model to explain physical education students' year-long development of course-specific gritperseverance (Study 1) and mental toughness (Study 2). In both studies, we used a randomized controlled trial research design with longitudinally assessed dependent measures (four waves) to test a hypothesized model in which teacher participation in an autonomy-supportive teaching workshop (experimental condition) would increase students' T2 perceived autonomy-supportive teaching and T2 perceived autonomy-supportive classmates, both of which would increase T3 need satisfaction, which would then explain longitudinal gains in students' T4 grit-perseverance (Study 1) and mental toughness (Study 2). In both Study 1 (57 teachers, 3,147 students) and Study 2 (38 teachers, 2,057 students), a multilevel structural equation modeling analysis showed that the hypothesized model fit the data very well. We conclude that the developmental roots of grit-perseverance and mental toughness can emerge proactively out of the asset-oriented experiences of interpersonal support and psychological need satisfaction that are central to self-determination theory.
