Web-Based and Face-To-Face Autonomy-Supportive Intervention for Physical Education Teachers and Students' Experiences.

The most of the previous autonomy-supportive interventions conducted have been partially effective and used only web-based or face-to-face approach. In the current study, a combined web-based and face-to-face intervention for physical education (PE) teachers was tested to examine whether it would lead to significant changes in students' self-reports of autonomy-supportive and controlling behaviours, psychological need satisfaction and frustration, and intrinsic motivation. Participants were 57 PE teachers ( = 45.

The Roles of Grit and Motivation in Predicting Children's Leisure-Time Physical Activity: One-Year Effects.

In this study, we tested two alternative models for investigating the ability of dimensions of personal grit (consistency of interest and perseverance of effort) and autonomous motivation to predict the leisure-time physical activity (LTPA) over a one-year period of 256 youth (aged 11-15 years at the beginning of the study). Specifically, we compared a model in which dimensions of grit were assumed to predict LTPA through autonomous motivation with a model in which autonomous motivation was assumed to predict LTPA through dimensions of grit. We tested the two models using variance-based structural equation modelling with Warp PLS v7.

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.

Motivational processes in physical education and objectively measured physical activity among adolescents.

Purpose: Grounded in self-determination theory (SDT), the present study tested how students' perceptions of autonomy support from physical education teachers predicts objectively measured moderate-to-vigorous physical activity (MVPA) of adolescents. According to SDT, it was expected that psychological needs and autonomous and controlled forms of motivation would mediate these relationships.

Methods: Students (n = 397) aged from 11 to 15 years in 17 different schools filled in questionnaires regarding SDT variables.

Detrimental Effect of Perceived Controlling Behavior from Physical Education Teachers on Students' Leisure-Time Physical Activity Intentions and Behavior: An Application of the Trans-Contextual Model.

In the present study, a trans-contextual model was applied to examine the relations between students' perceptions of controlling behavior from teachers, frustration over their basic psychological needs, autonomous motivation toward physical activity in a physical education context, autonomous motivation toward physical activity in an out-of-school context, beliefs and intentions toward future physical activity, and actual participation in physical activity outside of school. We adopted a three-wave prospective study design in which 234 students aged 11-19 years first completed measures of perceived controlling behavior from teachers, frustration over their basic psychological needs, and autonomous motivation toward physical activity in physical education. One week later, their autonomous motivation, beliefs, and intentions toward physical activity outside of school were measured.

Perceived Controlling Behaviors of Physical Education Teachers and Objectively Measured Leisure-Time Physical Activity in Adolescents.

The facilitative role of perceived autonomy support from physical education (PE) teachers on adolescents' leisure-time physical activity (PA) has been supported. This study aimed to examine the mechanism by which perceived controlling behaviors from PE teachers relate to adolescents' objectively measured leisure-time PA. In a three-wave prospective study, a total of 159 students (64 boys) aged 11 to 19 years old ( = 14.
