Personal and Psychosocial Predictors of Doping Use in Physical Activity Settings: A Meta-Analysis
Background There is a growing body of empirical evidence on demographic and psychosocial predictors of doping intentions and behaviors utilizing a variety of variables and conceptual models. However, to date there has been no attempt to quantitatively synthesize the available evidence and identify the strongest predictors of doping. Objectives Using meta-analysis, we aimed to (i) determine effect sizes of psychological (e.g. attitudes) and social-contextual factors (e.g. social norms), and demographic (e.g. sex and age) variables on doping intentions and use; (ii) examine variables that moderate such effect sizes; and (iii) test a path analysis model, using the meta-analyzed effect sizes, based on variables from the theory of planned behavior (TPB). Data Sources Articles were identified from online databases, by contacting experts in the field, and searching the World Anti-Doping Agency website. Study Eligibility Criteria and Participants Studies that measured doping behaviors and/or doping intentions, and at least one other demographic, psychological, or social-contextual variable were included. We identified 63 independent datasets. Study Appraisal and Synthesis Method Study information was extracted by using predefined data fields and taking into account study quality indicators. A random effects meta-analysis was carried out, correcting for sampling and measurement error, and identifying moderator variables. Path analysis was conducted on a subset of studies that utilized the TPB. Results Use of legal supplements, perceived social norms, and positive attitudes towards doping were the strongest positive correlates of doping intentions and behaviors. In contrast, morality and self-efficacy to refrain from doping had the strongest negative association with doping intentions and behaviors. Furthermore, path analysis suggested that attitudes, perceived norms, and self-efficacy to refrain from doping predicted intentions to dope and, indirectly, doping behaviors. Limitations Various meta-analyzed effect sizes were based on a small number of studies, which were correlational in nature. This is a limitation of the extant literature. Conclusions This review identifies a number of important correlates of doping intention and behavior, many of which were measured via self-reports and were drawn from an extended TPB framework. Future research might benefit from embracing other conceptual models of doping behavior and adopting experimental methodologies that will test some of the identified correlates in an effort to develop targeted anti-doping policies and programs.
360-degree video in education: An overview and a comparative social media data analysis of the last decade
Due to its immersive and interactive nature, 360-degree video is becoming ever more popular. However, little is known about the public’s viewpoints and attitudes regarding the use of this emerging technology in educational contexts. This study reviews the research evidence for 360° video, virtual learning environments and social media and presents related studies. Moreover, the methodology, the tools and the analysis process used to comparatively analyze social media data are presented and the results that arose are showcased. The use of 360° video in education is discussed and directions for future research are given. Based on the data from the last 10 years, the main findings of the study show that 360° video and its use in educational settings are recognized positively by the public who mostly express anticipation, trust and joy when referring to it. Nonetheless, teachers are unfamiliar with 360° video and do not have the necessary technical skills to develop educational material using it or incorporating it into teaching activities. Finally, 360° video is proven to be an effective educational tool which satisfies the emerging educational needs, enriches the teaching and learning process and promotes students’ motivation, active participation and engagement, rendering, thus, learning more effective.
Are nutritional supplements a gateway to doping use in competitive team sports? The roles of achievement goals and motivational regulations
The study investigated the moderating role of achievement goals and motivation regulations on the association between self-reported nutritional supplement (NS) use, doping likelihood, and self-reported doping behaviour among competitive athletes. Four hundred and ninety seven competitive team sport athletes (64% males; M age=23.54 years, SD=5.75) completed anonymous questionnaires measuring self-reported use of prohibited substances and licit NS; beliefs about the \"gateway\" function of NS; achievement goals; and motivational regulations. Hierarchical linear regression analysis showed that self-reported doping was associated (Adjusted R2=33%) with NS use, a stronger belief that NS use acts as a gateway to doping, amotivation, controlled motivation, mastery approach, and performance avoidance goals. Higher likelihood to use doping substances in the future was associated (Adjusted R2=41.7%) with current NS use, stronger belief that NS act as a gateway to doping, autonomous motivation, and performance avoidance goals. A series of moderated regression analyses showed that NS use significantly interacted with mastery approach, mastery avoidance, performance avoidance goals, autonomous motivation controlled motivation, and with amotivation in predicting self-reported doping. Finally, NS use significantly interacted with mastery approach goals, performance avoidance goals, and controlled motivation in predicting future doping likelihood. Achievement goals and motivational regulations are differentially associated with both doping likelihood and self-reported doping, and may account for the observed association between self-reported NS use and doping substances; thus, providing an alternative explanation to the \"gateway hypothesis\" that emphasizes the role of motivation.
A Preliminary Investigation of a Conceptual Framework of Performance Enhancement Across Different Life Domains
The use of chemically assisted performance enhancement (CAPE) substances has become a prominent trend in today's competitive societies. Although evidence suggests that CAPE behaviors across different life domains share common characteristics, no consistent theoretical framework exists for understanding the decision to engage in such behaviors. The aim of the present study was to examine a unified conceptualization of CAPE behaviors in four life domains. A total of 254 participants (64 competitive athletes, 40 recreational exercisers, 67 students, and 83 professionals) completed a survey assessing distal and proximal associations of CAPE behaviors (adapted for each domain). Path analysis used to evaluate the proposed model demonstrated an adequate fit. Results indicated that proximal associations of intentions (i.e., attitudes, norms, and situational temptation) were predicted by distal variables (i.e., social norms and cultural values). Intentions to engage in CAPE behaviors were predicted by attitudes and situational temptation. Goal commitment predicted only the mean of working, studying, or training. Finally, the mean of supplement use was predicted by norms. These findings provide preliminary evidence for a conceptual framework to understand CAPE behaviors across life domains, which may serve as a basis for designing intervention programs aimed at helping individuals make informed decisions about CAPE.
The Role of School Environment on the Sustainable Development of Pre-Schoolers’ Motor Creativity
This study examined the influence of student–teacher relationships and school infrastructure on preschool children’s motor creativity, encompassing fluency, originality, and imagination. Twenty teachers completed the Student–Teacher Relationship Scale for 200 children (10 children per teacher). The research team recorded aspects of the school’s physical environment through Movement Play Scale and assessed children’s motor creativity via the Thinking Creatively in Action and Movement test. The results revealed that dimensions of the student–teacher relationship, such as conflict and dependency, negatively impacted fluency, and originality components of motor creativity. Contrary to expectations, teacher participation in movement activities did not significantly contribute to motor creativity, potentially due to over-direction limiting children’s autonomy. Similarly, the school’s infrastructures were negatively linked to fluency and originality. The findings underscore the importance of nurturing autonomy-supportive environments and balancing guidance with opportunities for independent exploration. Teachers should also invest in adaptable educational spaces to foster creativity without encouraging dependency. This study emphasizes the critical role of supportive relational and environmental factors in shaping preschool children’s creative movement abilities.
Enhancing Preschoolers’ Motor Creativity Through Playfulness and Social Engagement
Background/Objectives: Motor creativity is a vital component of preschoolers’ growth and development. However, its underlying determinants remain largely underexplored. This study investigates the interrelationship among playful behavior, social profile, and motor creativity in preschool children, emphasizing its implications for holistic health and development. Methods: A total of 200 children and their kindergarten teachers from Greece participated in the study. The Children’s Playfulness Scale (CPS) was employed to assess the children’s playfulness, while a sociometric test was used to evaluate their social standing within peer groups. Motor creativity was measured through TCAM, a performance-based test focusing on fluency, imagination, and originality. Results: The findings revealed that the dimensions of playful behavior, particularly motor and social playfulness, significantly and positively influenced motor creativity, a core component of physical and mental health in early childhood. Conversely, certain aspects of social behavior had a negative association with imaginative capacities. Conclusions: The study underscores the critical role of movement-based playful activities in fostering children’s physical, emotional, cognitive, and social health. It highlights the need for educators to design developmentally appropriate motor play activities that cultivate creativity and social integration, promoting a balanced and health-oriented early education framework. The results contribute to educational policy and practice by reinforcing the importance of structured motor play in supporting preschoolers’ well-being and comprehensive development.
A preliminary investigation of the decision making process towards match fixing
Match fixing represents a major threat to sport integrity and action is needed to tackle this phenomenon across levels and types of sport. The present study examined, for the first time, the psychological factors associated with athletes’ intentions to engage in match fixing, by utilizing the Theory of Planned Behaviour. Ninety nine athletes from team sports (M = 21.98 years, SD = 2.25) participated in the study and completed a survey measuring the variables of TPB (i.e., attitudes, subjective norms, perceived behavioural control, and intentions). The results of the analyses indicated that approximately 30% of the athletes reported that have been engaged in a match that they believe was fixed, and intentions to engage in match fixing were significantly associated with perceived social approval of match fixing among referent others. Further analysis showed that athletes with prior experience of match fixing also perceived stronger social norms in favor of match fixing as compared to athletes without such experience. Our findings are novel and have implications about the role of social norms in understanding and preventing match fixing in sport, and we provide specific recommendation for future studies and policy-making in this area.
A Whole-School Approach for the Promotion of Physical Activity: An Evaluation of Stakeholders’ and Educators’ Perceptions About Education in Six European Countries
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, an exploratory mixed methods design was employed. Initially, a qualitative study with academics and stakeholders was conducted, followed by a quantitative investigation with teachers and school employees. In the first study, seven participants working in education took part in one-to-one interviews concerning their views on the usefulness, content, and delivery of whole-school education. The participants stressed the importance of the WSA and urged that educational authorities should consider the needs of children and the school community, promote teacher collaboration, pursue longevity, and engage with stakeholders and institutions throughout the process. In the second study, 160 school teachers and staff answered a survey about the content and delivery mode of an educational material for the promotion of WSA to fostering physical activity. The analyses indicated that participants preferred a three to six hours course, a hybrid mode of delivery, inclusion of best practices, and knowledge on how to implement a WSA. The study’s findings reveal several implications and recommendations for educators creating comprehensive school-based physical activity programs.
Effects of a Diabetes Sports Summer Camp on the Levels of Physical Activity and Dimensions of Health-Related Quality of Life in Young Patients with Diabetes Mellitus Type 1: A Randomized Controlled Trial
Physical activity (PA) is considered an important part of the treatment of children with diabetes mellitus type 1 (T1DM). 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-four children and adolescents with T1DM were randomly assigned into an intervention (M = 12.64, SD = 1.82, 30 female) and a control group (M = 12.67, SD = 2.50, 30 female). Intervention group participants attended a ten-day summer diabetes sports camp which included an intensive program of PA (6 h of daily PA), educational and entertaining activities as well as education on the importance of PA in the management of the disease. At baseline and at the end of the study, participants completed measures of physical activity, self-esteem, depression, health status, intention to change behavior, and life satisfaction. Results of the two-way repeated measures analysis showed no statistically significant group differences in PA levels (p < 0.05) and HRQoL parameters (p < 0.05 for all parameters). In conclusion, the results did not support the effectiveness of a 10-day diabetes sports camp on PA levels and HRQoL for children with T1DM. Longer interventions may be more effective in exerting positive influence on trait parameters of children with T1DM’s quality of life. Participation in such programs on multiple occasions should be evaluated in the future.
