This study examined health indicators and health-related behaviors in esports players and explored differences by weekly playtime and nationality. Methods A cross-sectional online survey was completed by 413 esports players from 48 nationalities. Measures included body mass index (BMI), physical a…
A Whole-School Approach for the Promotion of Physical Activity
Research has shown that a whole-school approach (WSA) is needed to increase student physical activity. There is a lack of empirical data on teachers’ opinions and needs regarding the implementation of a WSA approach to encourage physical activity. Our study aims to address this gap by identifying teachers’ and academics’ beliefs about the usefulness, content, and delivery mode of a WSA in fostering physical activity. To address the research aim, …
A longitudinal investigation of the reciprocal associations between motivational climate and need satisfaction in Finnish high school students
Background and purpose Although existing evidence is predominantly based on cross-sectional data, there are limited longitudinal studies exploring how different dimensions of motivational climate influence basic psychological needs over time. Grounded in self-determination and achievement goal theories, this study investigates the longitudinal relationship between motivational climate and basic need satisfaction in Finnish students, emphasizing t…

Athletes’ Perceptions and Knowledge About Match Fixing
Bridging Cultures in Education
Contemporary school settings are characterized by multiculturalism; Thus, the cultivation of intercultural competence stands as a key element for the promotion of tolerance and acceptance as well as for the elimination of racism and xenophobia. Even though the importance of intercultural education is understood as an emergent issue, educators seem to be unprepared when it comes to the teaching process. Under this rationale, this research aims to …
Qualitative analysis of the factors associated with whistleblowing intentions among athletes from six European countries
Although whistleblowing is thought to represent an effective mechanism for detecting and uncovering doping in sport, it has yet to become a widely adopted practice. Understanding the factors that encourage or discourage whistleblowing is of vital importance for the promotion of this practice and the development of pedagogical material to enhance the likelihood of whistleblowing. The current study employed a qualitative methodology to explore the …

Furthermore, health-related quality of life (HRQoL) affects both the physical and mental health of patients with T1DM. The purpose of the study was to evaluate through a randomized controlled trial the impact of participation in a summer diabetes sports camp on the PA and HRQoL of children and adolescents with T1DM. Eighty-fou…
Are dietary supplement users more likely to dope than non-users
Context matters
BackgroundAlthough athletes seem to hold uniform views towards non-dopers, their perception of dopers is more nuanced, reflecting positive and negative attributes. Research also indicates that rarely a single factor can explain doping, but a host of reasons that intertwine. A holistic understanding of how values play a role in decisions in anti-doping and the elements that influence athletes' doping vulnerability is timely and warranted.MethodsWe…

The study’s aim was to investigate the acceptability and usability of an online e-learning course and an information app designed to support PIED prevention training activities in professionals working with recreational athletes.Design A mixed-method design was used with 51 profes…
Staying Active under Restrictions
The COVID-19 pandemic and the associated governmental restrictions suddenly changed everyday life and potentially affected exercise behavior. The aim of this study was to explore whether individuals changed their preference for certain types of physical exercise during the pandemic and to identify risk factors for inactivity. An international online survey with 13,881 adult participants from 18 countries/regions was conducted during the initial C…
Performance and image enhancing drug interventions aimed at increasing knowledge among healthcare professionals (HCP)
One Does Not Fit All
Doping violates the Spirit of Sport and is thought to contradict the values which underpin this spirit. Values-based education (VBE) has been cited as a key element for creating a clean sport culture across age groups. Culturally relevant VBE requires understanding of the values that motivate athletes from different countries to practice their sport and uphold clean sport values. WADA's new International Standards for Education makes this study b…

Face-to-face bullying and cyberbullying in adolescents
Tackling psychosocial risk factors for adolescent cyberbullying
Cyberbullying is an emerging form of bullying that takes place through contemporary information and communication technologies. Building on past research on the psychosocial risk factors for cyberbullying in this age group, the present study assessed a theory-driven, school-based preventive intervention that targeted moral disengagement, empathy and social cognitive predictors of cyberbullying. Adolescents (N = 355) aged between 16 and 18 years w…
Structural validation and cross-cultural robustness of the European Cyberbullying Intervention Project Questionnaire
The Psychology of Doping in Sport
This is the first book to draw together cutting-edge research on the psychological processes underlying doping use in sport and exercise, thereby filling an important gap in our understanding of this centrally important issue in contemporary sport. Covering diverse areas of psychology such as social cognition, automatic and controlled processes, moral decision-making, and societal and contextual influence on behaviour, the book also explores meth…
A matter of mind-set in the interpretation of forensic application

The relation between balanced need satisfaction and adolescents’ motivation in physical education
Self-determination theory posits that satisfaction of the needs for autonomy, competence and relatedness represents the basic nutriments for humans’ optimal functioning. It also postulates that with greater the degree to which these three needs are equally satisfied, the quality of motivation is further enhanced. Yet, this premise has remained relatively underexplored. In this correlational study, we surveyed Greek middle-school students ( N = 43…
Extending the trans-contextual model in physical education and leisure-time contexts
Background. The trans-contextual model (TCM) is an integrated model of motivation that aims to explain the processes by which agentic support for autonomous motivation in physical education promotes autonomous motivation and physical activity in a leisure-time context. It is proposed that perceived support for autonomous motivation in physical education is related to autonomous motivation in physical education and leisure-time contexts. Furthermo…
Manipulation of motivational climate in physical education
The objective of this study was to examine the impact of an intervention programme that manipulated task, authority, recognition, grouping, evaluation and time (TARGET) structures on the cognitive and affective response of students to their physical education (PE) lesson. The sample consisted of 374 high school students ( M age = 13.8, S.D. = .73) assigned to either an intervention or a control group. The students completed measures of perception…

Achievement goals in physical education
The aim of the present study was to investigate the differential relationships between five dimensions of motivational climate and achievement goals, as the latter have been conceptualized by the revised achievement goal theory. Adolescents ( N = 336, M age = 13.45 years, SD = 1.04) participating in a summer camp in southern Greece took part in the study. The participants completed the Approach Avoidance Achievement Goal Questionnaire (AAAGQ; mea…

Evaluation of students’ social ability
Comparing dichotomous and trichotomous approaches to achievement goal theory
Background. It is commonly assumed that there is conceptual equivalence between the task and ego achievement goals proposed by Nicholl's (1989) dichotomous achievement goal theory ( Nicholls, 1989 ), and the mastery and performance approach goals advanced by Elliot's (1997) trichotomous hierarchical model of approach and avoidance achievement motivation. Aims. Our study examined whether this conceptual equivalence is reflected in measurement equi…
