Brief Summary

This project aims to develop a three-month face-to-face and web-based intervention program for physical education (PE) teachers to increase autonomy, competence, and relatedness supportive behaviour toward their students and to avoid the respective need-thwarting behaviours toward their students. The effectiveness of the intervention program is examined at multiple time points during the three-month period. After the intervention program, it is expected that the experimental group students demonstrate significantly higher intrinsic motivation toward physical activity (PA) and are significantly more physically active, as measured by accelerometers, compared to control group students. Additionally, unique effects of autonomy, competence, and relatedness support interventions on students' intrinsic motivation and PA will be investigated. This project provides highly valuable input for PE teacher training to increase students' intrinsic motivation and their overall PA.

Detailed Description

Aim of the study

The main objective of the project is to develop and test the main and combined effects of the PE teachers' face-to-face and web-based need-supportive intervention on Grade 6 to 7 adolescents' leisure time PA. The secondary objective of the project is to test the unique effects of interventions focused on support for each psychological need (i.e., autonomy, competence, and relatedness) separately.

Detailed Description

Background

Research has consistently demonstrated that regular PA is associated with several cognitive, psychological, mental, and physical benefits among adolescents (Rodriguez Ayllon et al., 2019). However, PA levels among adolescents are low worldwide (Sluijs et al., 2021) and tend to decrease with age (Farooq et al., 2018). Low PA during childhood and adolescence increases the risk of chronic diseases in adulthood, leading to higher morbidity and lower quality of life (Mavrovouniotis, 2012). Consequently, researchers aim to identify psychological antecedents of PA to inform effective interventions.

PE lessons provide an ideal environment for conveying health-related messages to adolescents (Powell et al., 2016). PE teachers can support students' autonomy, competence, and relatedness, fostering intrinsic motivation in both PE and leisure-time PA. The trans-contextual model of motivation (TCM) has been extensively used to identify PA determinants in these contexts (Hagger et al., 2003). This model integrates self-determination theory (SDT) (Ryan & Deci, 2017), the theory of planned behaviour (Ajzen, 1991), and Vallerand's hierarchical model of motivation (Vallerand, 1997). One core assumption is that psychological experiences in one context (e.g., PE) influence others (e.g., leisure time) (Hagger et al., 2003). Studies indicate that PE teachers significantly impact students' intrinsic motivation (Aibar et al., 2022; Chang et al., 2016; Kalajas-Tilga et al., 2020). Enhancing PE teachers' autonomy-supportive behaviours is crucial (Reeve & Cheon, 2021). Recent research shows that combining web-based and face-to-face interventions effectively improves PE-related outcomes, such as basic psychological needs (BPN) satisfaction and motivation (Tilga et al., 2021).

Few TCM-guided studies have shown changes in students' PA behaviour during leisure time (e.g., Polet et al., 2021; Schneider et al., 2020), and previous autonomy-supportive interventions have been only partially effective (e.g., Rhodes et al., 2021). There is a scarcity of intervention studies supporting a SDT-based multidimensional approach to promote adolescents' PA participation (Ferriz et al., 2021). Recent findings emphasize the importance of providing autonomy, competence, and relatedness support to fully satisfy BPN-s and enhance intrinsic motivation (Ahmadi et al., in press). It is also crucial to avoid need-thwarting behaviours, as these negatively impact adolescents' outcomes (Ahmadi et al., in press; Haerens et al., 2015; Tilga et al., 2020).

In a Delphi study, Ahmadi and colleagues (2023) classified autonomy, competence, and relatedness support and thwarting behaviours, resulting in a taxonomy of 57 teacher motivational behaviours. A shortlist of 22 behaviours was created by selecting those with mean effect ratings greater than +2, categorized as need-supportive and need-thwarting teaching techniques. This classification is the first to systematically compile expert perspectives on motivational teacher behaviours in education. Building on this taxonomy, researchers can test and apply these behaviours in schools. Ferriz and colleagues (2023) adapted these behaviours to the PE context. This project aims to develop and test an intervention program to enhance PE teachers' supportive behaviours and reduce their thwarting behaviours toward students.

To our knowledge, no studies have combined face-to-face and web-based interventions in PE to enhance teachers' need-supportive behaviours while diminishing need-thwarting behaviours, with the goal of increasing students' intrinsic motivation in PE and leisure-time PA.

Participants

For the main trial phase 1, the statistical power analysis revealed that a minimum sample size of 78 students (i.e., n = 39 students allocated to each of the two study groups) would be required to achieve 80% statistical power to detect medium effect sizes when considering three measurements (baseline vs. one-month vs. three-month follow-up) at the within-subject level (correlated at 0.50), with an alpha level of 0.05. However, considering the possible dropout rate of approximately 40% evident in multiple follow-up studies of physical activity (Duda et al., 2014), the investigators aim to recruit 130 students at baseline (i.e., 65 students allocated to each of the two study groups).

For the main trial phase 2, the statistical power analysis revealed that a minimum sample size of 116 students (i.e., n = 29 students allocated to each of the four study groups) would be required to achieve 80% statistical power to detect medium effect sizes when considering three measurements (baseline vs. one-month vs. three-month follow-up) at the within-subject level (correlated at 0.50), with an alpha level of 0.05. However, considering the possible dropout rate of approximately 40% evident in multiple follow-up studies of physical activity (Duda et al., 2014), the investigators aim to recruit 196 students at baseline (i.e., 49 students allocated to each of the four study groups).

Interventions

Combined face-to-face and web-based need-supportive intervention

There will be four types of different intervention programs:

For the main trial phase 1, there will be a combined face-to-face and web-based autonomy, competence, and relatedness need-supportive intervention program with a duration of two months. During these two months, there will be three face-to-face meetings: at the beginning of the course, at the beginning of the fifth week of the course, and at the beginning of the eighth week of the course (each lasting approximately four hours and consisting of lectures and practical activities with discussions).

Additionally, there will be weekly new materials for PE teachers via a web-based learning platform (Moodle) developed for this project. PE teachers will be required to report weekly on how they provide need support to their students and avoid need-thwarting behaviours through the web-based learning platform. Throughout this online course, PE teachers will receive specific materials about all need-supportive behaviours (a total of 9 specific behaviours) and need-thwarting behaviours (a total of 13 specific behaviours) proposed by Ahmadi and colleagues (2023), and adapted for PE by Ferriz and colleagues (2023). This material contains detailed descriptions of each behaviour along with several real-life examples. Additionally, PE teachers will complete a topic-related test at the end of each week in the online environment to confirm their understanding of the material.

For the main trial phase 2, there will be three different courses:

• A combined face-to-face and web-based autonomy need-supportive intervention program with a duration of one month.
• A combined face-to-face and web-based competence need-supportive intervention program with a duration of one month.
• A combined face-to-face and web-based relatedness need-supportive intervention program with a duration of one month.

All these courses will be identical, with the exception that each course focuses on a specific basic psychological need-autonomy, competence, or relatedness. Each course will begin with a face-to-face meeting, which will be the only face-to-face meeting for that course. The content of this face-to-face meeting will be similar to that of the face-to-face meeting experienced in the main trial phase 1.

Study Groups

Two-month face-to-face and web-based need-supportive intervention program for PE teachers (Trial 1)

The main trial phase 1 For the web-based course, we will create video lectures introducing PE teachers' interpersonal behaviours, students' BPN-s, and different motivational regulations in the field of PE to provide a general overview of the SDT postulates. We will also produce short videos on each need-supportive and need-thwarting behaviour, featuring real-life examples of how to increase specific need-supportive behaviours (a total of 9 videos) and how to avoid each specific need-thwarting behaviour (a total of 13 videos), with an approximate duration of 5-8 minutes for each video. In the face-to-face course, PE teachers will also have the opportunity to experience highly need-supportive and highly need-thwarting PE lessons as students, allowing them to reflect on these experiences later.
