Who influences whom
Background Student motivation for Physical Education (PE) is a key predictor of positive outcomes. Much of the existing research, grounded in Self-Determination Theory (SDT), highlights the influential role of PE teachers' (de)motivating styles on student motivation. However, this teacher-focused perspective tends to overlook students' active role in shaping the classroom environment. According to the Transactional Model, a two-way pathway exists…
Observing physical education teachers’ need-supportive and need-thwarting styles using a circumplex approach
Background: Self-Determination Theory-based studies showed that teachers’ need-supportive styles (i.e. autonomy-supportive and structuring) enhance students’ motivation and well-being, while teachers’ need-thwarting styles (i.e. being controlling and chaotic), have been related to several detrimental outcomes. The value of jointly depicting teachers’ need-supportive and need-thwarting styles in a circular structure has been shown based on multidi…
Chaotic (laissez-faire) teaching
How pre-service physical education teachers’ motivational profiles shape their (de)motivating teaching profiles
Following a cross-sectional design with 554 pre-service physical education teachers ( M age = 25.03 years-old; SD = ± 4.31; 67.8 % male), this study aimed to identify their motivational and teaching profiles and examine the relationships between them. Four distinct motivational profiles and four teaching profiles emerged. More self-determined motivational profiles were associated with more adaptive teaching profiles. Conversely, less self-determi…
Exploring (de-)motivating teaching profiles from a fine-grained directiveness approach
The aim was to examine how structuring and controlling approaches (high directiveness), and autonomy-supportive and chaotic approaches (low directiveness) were combined and related to students’ needs in physical education. In a sample of 1124 secondary school students, this cross-sectional study conducted two sets of profile analyses, respectively for high and low directiveness, were conducted. The latent profile analyses (LPA) revealed four high…

Need satisfaction and frustration among early career teachers
Towards a refined insight into physical education teachers’ autonomy-supportive, structuring, and controlling style to the importance of student motivation
Background: Physical education (PE) teachers face the challenge of managing their classroom and directing students’ learning in a way that engages students in a motivating manner. For this reason, numerous studies have examined the impact of PE teachers’ autonomy-supportive, structuring, and controlling style. Most research relied on a variable-centered approach, but a person-centered approach is warranted as in reality these styles co-occur. Pri…
How is observed (de)motivating teaching associated with student motivation and device-based physical activity during physical education
Previous Self-Determination Theory (SDT) research has highlighted the impact of physical education (PE) teachers’ (de)motivating styles on students’ motivation, in-class moderate-to-vigorous physical activity (MVPA), and sedentary behaviour. However, most studies relied on questionnaires to assess PE teachers’ (de)motivating styles, and the few that used observations focused primarily on one specific (de)motivating style in relation to motivation…

Toward a Refined Insight Into the Importance of Volunteers’ Motivations for Need-Based Experiences, Job Satisfaction, Work Effort, and Turnover Intentions in Nonprofit Sports Clubs
Extensive variable-centered research guided by Self-Determination Theory (SDT) has provided insights into volunteers’ motivations in nonprofit and voluntary sports clubs. However, volunteers may have multiple reasons for engaging in volunteer work. By adopting a person-centered approach, the present study aimed to identify volunteers’ motivational profiles in sports clubs based on combinations of different motivational regulations as distinguishe…
The Relation between Physical Education Teachers’ (De-)Motivating Style, Students’ Motivation, and Students’ Physical Activity
Research suggests that physical education (PE) teachers can play a crucial role in the promotion of students' physical activity. Grounded in Self-Determination Theory, this study investigated how students' perceptions of PE teachers (de-)motivating style relate to students' device-based physical activity levels during PE. Moreover, it was examined whether students' motivation plays an intervening role in this relation and whether students' physic…
Adolescents’ physical activity and sedentary behaviour in Indonesia during the Covid-19 pandemic
During the pandemic, mothers perceived their children to be less active and using more screen-based devices, either for educational or recreational purposes, compared to before. The present themes might be useful when developing interventions and policies promoting physical activity and reducing sedentary behaviour in adolescents. Interventions could, for example, consider increasing parents' and adolescents' awareness on current activity guideli…
A Descriptive Epidemiology of Screen-Based Devices by Children and Adolescents
Controversies in the Science of Sedentary Behaviour and Health
The development in research concerning sedentary behaviour has been rapid over the past two decades. This has led to the development of evidence and views that have become more advanced, diverse and, possibly, contentious. These include the effects of standing, the breaking up of prolonged sitting and the role of moderate-to-vigorous physical activity (MVPA) in the association between sedentary behaviour and health outcomes. The present aim is to…
Differences in Context-Specific Sedentary Behaviors According to Weight Status in Adolescents, Adults and Seniors
To develop effective sedentary behavior interventions aimed at people who are overweight/obese, detailed insight is needed into the contexts of sedentary behavior of these people. Therefore, the aims of this study were to describe the composition of sedentary behavior and to compare context-specific sedentary behaviors between different weight groups. Cross-sectional data were used from a study conducted in 2013−2014 among a Flemish sample of ado…
From Evidence-Based Research to Practice-Based Evidence
Prolonged sitting has been linked to adverse health outcomes; therefore, we developed and examined a web-based, computer-tailored workplace sitting intervention. As we had previously shown good effectiveness, the next stage was to conduct a dissemination study. This study reports on the dissemination efforts of a health promotion organisation, associated costs, reach achieved, and attributes of the website users. The organisation systematically r…
School Gardens
School gardens have beneficial effects on children's dietary behaviors but information on its implementation is scarce. The current study aimed to gain insight in implementation practices of school gardens and in perceptions of key members and children towards a school garden. We conducted twelve interviews involving 14 key members and five focus groups with 38 children from fifth to sixth grade (10-13 years old) in four primary schools in Ghent …
Cross-Sectional Associations between Home Environmental Factors and Domain-Specific Sedentary Behaviors in Adults
Despite the negative health effects of too much sitting, the majority of adults are too sedentary. To develop effective interventions, insight is needed into home environmental correlates of adults' sedentary behaviors, and into the susceptibility of population subgroups to these home environmental cues. In total, 559 Flemish adults reported socio-demographics, weight and height, home environmental factors and domain-specific sedentary behaviors.…
Views of policy makers and health promotion professionals on factors facilitating implementation and maintenance of interventions and policies promoting physical activity and healthy eating
Despite considerable heterogeneity of interventions and health policies in the five countries, stakeholders across these countries identify similar factors facilitating adoption, implementation, and maintenance of these interventions and policies
What are the working mechanisms of a web-based workplace sitting intervention targeting psychosocial factors and action planning

The associations between domain-specific sedentary behaviours and dietary habits in European adults
Domain-specific sitting behaviours were related to unhealthy dietary behaviours. However, the small effect sizes suggest that individual level behavioural interventions focusing on sedentary behaviour will not be sufficient to improve dietary habits. The fact that almost none of the associations were moderated by age or gender suggests that these associations, and possibly also the effects of interventions targeting both behaviours, may hold acro…
Theory-driven, web-based, computer-tailored advice to reduce and interrupt sitting at work
It is feasible to reach employees with this tool. Most of the employees who requested the advice found it acceptable and reported they changed their behaviour or intended to change it. Interrupting sitting appeared more achievable than reducing workplace sitting

How many steps/day are enough? for adults
Physical activity guidelines from around the world are typically expressed in terms of frequency, duration, and intensity parameters. Objective monitoring using pedometers and accelerometers offers a new opportunity to measure and communicate physical activity in terms of steps/day. Various step-based versions or translations of physical activity guidelines are emerging, reflecting public interest in such guidance. However, there appears to be a …
Socio-demographic, psychosocial and home-environmental attributes associated with adults' domestic screen time
Educational level, age, self-efficacy and pros/cons were the most important correlates identified in this study. If further cross-sectional and longitudinal research can confirm these findings, tailored interventions focusing on both psychosocial and environmental factors in specific population subgroups might be most effective to reduce domestic screen time
The impact of disseminating the whole-community project '10,000 Steps'
10,000 Steps' shows potential for wide-scale dissemination but a supportive linkage system seems recommended to encourage adoption levels and high quality implementation
Self-reported physical activity in European adolescents
Objective To describe self-reported physical activity (PA) patterns in the various domains (school, home, transport, leisure time) and intensity categories (walking, moderate PA, vigorous PA) in European adolescents. Furthermore, self-reported PA patterns were evaluated in relation to gender, age category, weight status category and socio-economic status (SES). Design Cross-sectional study. Setting Ten European cities. Subjects In total, 3051 ado…
Sustainability of the whole-community project '10,000 Steps'
10,000 Steps' could remain sustainable but design, organizational, and contextual barriers need consideration. Sustainability of '10,000 Steps' in organizations can occur in cycles rather than in ongoing projects. Future research should compare sustainability other whole-community PA projects with '10,000 Steps' to contrast sustainability of alternative models of whole-community PA projects. This would allow optimization of project elements and m…
Can differences in physical activity by socio-economic status in European adolescents be explained by differences in psychosocial correlates? A mediation analysis within the Helena (Healthy Lifestyle …
Objective Socio-economic status (SES) has been positively associated with physical activity (PA) levels in adolescents. In order to tackle these social inequalities, information is needed about the underlying mechanisms of this association. The present study aimed to investigate the potential mediating role of psychosocial correlates of PA on the relationship between SES and PA in European adolescents. Design Cross-sectional study testing the med…
A cost-effectiveness study of the community-based intervention ‘10 000 Steps Ghent’
Objective To evaluate the cost-effectiveness of the European community-based project ‘10 000 Steps Ghent’, an intervention that resulted in a significant decrease in sedentary time and a significant increase in step counts (896 steps/d) and self-reported walking (66 min/week). Design An age- and gender-dependent Markov model, with a time horizon of 20 years and a cycle length of 1 year, estimating the development of diabetes, cardiovascular event…
Evaluation of a workplace intervention to promote commuter cycling
The results of the dissemination study are promising. The adoption and implementation rates indicate that the 'Bike to Work: cyclists are rewarded' program seems to be a feasible workplace intervention. At the individual level, a higher score of commuter cycling was found among the employees aware of the program. Nevertheless, more evidence regarding long term effectiveness and sustainability of the intervention is needed
Evaluation of a real world intervention using professional football players to promote a healthy diet and physical activity in children and adolescents from a lower socio-economic background
The 'Health Scores!' intervention was successful in increasing psychosocial correlates of a healthy diet and PA. The use of professional football players as a credible source for health promotion was appealing to socially vulnerable children and adolescents
