Trans-Contextual Model Predicting Change in Out-of-School Physical Activity: A One-Year Longitudinal Study
The aim of the current study was to test the long-term predictive validity of the trans-contextual model in accounting for variance in adolescents’ out-of-school physical activity measured by self-report and accelerometer based-devices over a one-year period. Secondary school students ( N = 265) aged 11 to 15 years completed a three-wave survey on two occasions in time, spanning a one-year interval, measuring perceived autonomy support in physical education (PE), peer and parent autonomy support in leisure-time, autonomous and controlled motivation in PE and leisure-time, attitude, subjective norms, perceived behavioural control, intention, and out-of-school physical activity both by sel…
Application of the trans-contextual model to predict change in leisure time physical activity
Objective: This study tested effects of changes in the psychological constructs of the trans-contextual model (TCM) on changes in adolescents' outside of school moderate-to-vigorous physical activity (PA) measured using self-report and accelerometer-based device. Design: A three-wave longitudinal design was used. High school students (N = 331) completed measures of all the TCM constructs at Time1 and at Time2, five weeks apart. Self-reported PA behaviour was measured also at Time3, five weeks after Time2. PA was measured using accelerometer-based devices for seven days following Time1 and Time3 for a census week. Results: A structural equation model using residual change scores revealed tha…
