Psychosocial predictors of doping intentions and use in sport and exercise: a systematic review and meta-analysis.

OBJECTIVE: To conduct a meta-analytic review of psychosocial predictors of doping intention, doping use and inadvertent doping in sport and exercise settings. DESIGN: Systematic review and meta-analysis. DATA SOURCES: Scopus, Medline, Embase, PsychINFO, CINAHL Plus, ProQuest Dissertations/Theses and Open Grey. ELIGIBILITY CRITERIA: Studies (of any design) that measured the outcome variables of doping intention, doping use and/or inadvertent doping and at least one psychosocial determinant of those three variables. RESULTS: We included studies from 25 experiments (N=13 586) and 186 observational samples (N=3 09 130). Experimental groups reported lower doping intentions (g=-0.21, 95% CI (-0.31 to -0.12)) and doping use (g=-0.08, 95% CI (-0.14 to -0.03), but not inadvertent doping (g=-0.70, 95% CI (-1.95 to 0.55)), relative to comparators. For observational studies, protective factors were inversely associated with doping intentions (z=-0.28, 95% CI -0.31 to -0.24), doping use (z=-0.09, 95% CI -0.13 to to -0.05) and inadvertent doping (z=-0.19, 95% CI -0.32 to -0.06). Risk factors were positively associated with doping intentions (z=0.29, 95% CI 0.26 to 0.32) and use (z=0.17, 95% CI 0.15 to 0.19), but not inadvertent doping (z=0.08, 95% CI -0.06 to 0.22). Risk factors for both doping intentions and use included prodoping norms and attitudes, supplement use, body dissatisfaction and ill-being. Protective factors for both doping intentions and use included self-efficacy and positive morality. CONCLUSION: This study identified several protective and risk factors for doping intention and use that may be viable intervention targets for antidoping programmes. Protective factors were negatively associated with inadvertent doping; however, the empirical volume is limited to draw firm conclusions.

An intervention to optimise coach-created motivational climates and reduce athlete willingness to dope (CoachMADE): a three-country cluster randomised controlled trial.

OBJECTIVES: Coach-centred antidoping education is scarce. We tested the efficacy of a motivationally informed antidoping intervention for coaches, with their athletes' willingness to dope as the primary outcome. METHODS: We delivered a cluster randomised controlled trial in Australia, the UK and Greece. This study was a parallel group, two-condition, superiority trial. Participants were 130 coaches and 919 athletes. Coaches in the intervention group attended two workshops and received supplementary information to support them in adopting a motivationally supportive communication style when discussing doping-related issues with their athletes. Coaches in the control condition attended a standard antidoping workshop that provided up-to-date information on antidoping issues yet excluded any motivation-related content. Assessments of willingness to dope (primary outcome) and other secondary outcomes were taken at baseline, postintervention (3 months) and at a 2-month follow up. RESULTS: Compared with athletes in the control group, athletes in the intervention group reported greater reductions in willingness to take prohibited substances (effect size g=0.17) and psychological need frustration (g=0.23) at postintervention, and greater increases in antidoping knowledge (g=0.27) at follow-up. Coaches in the intervention group reported at postintervention greater increases in efficacy to create an antidoping culture (g=0.40) and in perceived effectiveness of need supporting behaviours (g=0.45) to deal with doping-related situations. They also reported greater decreases in doping attitudes (g=0.24) and perceived effectiveness of need thwarting behaviours (g=0.35). CONCLUSIONS: Antidoping education programmes should consider incorporating principles of motivation, as these could be beneficial to coaches and their athletes. We offer suggestions to strengthen these programmes, as most of the effects we observed were not sustained at follow-up. TRIAL REGISTRATION NUMBER: This trial has been registered with the Australian New Zealand Clinical Trials Registry (https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=371465&isReview=true).

Whistleblowing against doping in sport: A cross-national study on the effects of motivation and sportspersonship orientations on whistleblowing intentions.

Whistleblowing against anti-doping rule violations and related misconduct has been recognized as an important deterrent of doping behaviour in competitive sport. However, research on whistleblowing against doping is scarce and the available studies have focused on small samples using qualitative and inductive approaches. The present study used quantitative methods to assess, for the first time, the association between self-determined motivation, achievement goals, sportspersonship orientations and intentions to engage in whistleblowing against doping misconduct. A total of 992 competitive athletes from Greece (n = 480) and Russia (n = 512) completed structured measures of self-determination, achievement goals, sportspersonship orientation beliefs, and intentions to report doping misconduct. Latent profile analysis classified athletes into clusters consistent with the theoretical predictions. One-way analyses of variance further showed consistently across countries that autonomous motivated athletes reported higher intentions to whistleblow, and athletes with higher scores in achievement goals and sportspersonship orientations had significantly higher scores in whistleblowing intentions, compared to those with lower scores in these characteristics in both countries. This is the first study to demonstrate the association between motivational regulations, achievement goals, sportspersonship beliefs, and whistleblowing intentions. The theoretical and policy implications of our study are discussed.

Whistleblowing Against Doping Misconduct in Sport: A Reasoned Action Perspective With a Focus on Affective and Normative Processes.

Whistleblowing against doping misconduct represents an effective deterrent of doping use in elite competitive sport. The present study assessed the effects of social cognitive variables on competitive athletes' intentions to report doping misconduct. A second objective was to assess whether the effects of social norms on whistleblowing intentions were mediated by actor prototype evaluations and group identification and orientation. In total, 1,163 competitive athletes from Greece, Russia, and the United Kingdom completed a questionnaire on demographics, past behavior, social cognitive variables, and intentions toward whistleblowing. Regression analyses showed that whistleblowing intentions were associated with different social cognitive variables in each country. Multiple mediation modeling showed that attitudes and subjective norms were associated with whistleblowing intentions indirectly, via the effects of anticipated negative affect and group identification and orientation, respectively. The findings of this study are novel and have important implications about the social, cognitive, and normative processes underlying decision making toward reporting doping misconduct.

The role of the athletes' entourage on attitudes to doping.

The present study investigated athletes' and coaches' beliefs about the role of athletes' entourage in deterring or promoting doping. Competitive athletes and coaches in Greece and Australia took part in semi-structured interviews. Our analysis of the interviews produced five main themes: coach influence, peer influence, doping stance, doping stigma, and entourage's culture. Overall, coaches and peers having a close and trusty relationship with the athletes were considered most influential with respect to doping-related decisions. The majority of the athletes held a strong anti-doping stance but could not articulate why they held this position. This inability could be ascribed to the stigmatization of doping which led to lack of knowledge and anti-doping education. Finally, an anti-doping culture in the athletes' environment was considered central to an anti-doping stance. The study findings provide valuable information towards a comprehensive understanding of the role athletes' entourage can play in shaping athletes' attitudes and decision for doping.

Linking Coach Interpersonal Style With Athlete Doping Intentions and Doping Use: A Prospective Study.

We brought together various lines of work on motivation, morality, and doping by testing a theory-based model prospectively linking contextual and personal motivational variables, moral attitudes, moral disengagement in doping, doping intentions, and doping use. Participants were 257 Greek athletes who completed a questionnaire pack at the beginning of a sport season. In the case of doping use, we also obtained data close to the end of the same season. The model showed that perceptions of controlling coach behaviors predicted athlete need frustration, which in turn predicted low moral functioning and doping intentions/doping use. The findings highlight pathways (direct and indirect) by which the social environment may impact on athletes' intentions and decisions to engage in doping and could pave the way for future antidoping interventions aimed at improving coaching interpersonal style.

Tackling psychosocial risk factors for adolescent cyberbullying: Evidence from a school-based intervention.

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 were randomly assigned into the intervention and the control group. Both groups completed anonymous structured questionnaires about demographics, empathy, moral disengagement and cyberbullying-related social cognitive variables (attitudes, actor prototypes, social norms, and behavioral expectations) before the intervention, post-intervention and 6 months after the intervention. The intervention included awareness-raising and interactive discussions about cyberbullying with intervention group students. Analysis of covariance (ANCOVA) showed that, after controlling for baseline measurements, there were significant differences at post-intervention measures in moral disengagement scores, and in favorability of actor prototypes. Further analysis on the specific mechanisms of moral disengagement showed that significant differences were observed in distortion of consequences and attribution of blame. The implications of the intervention are discussed, and guidelines for future school-based interventions against cyberbullying are provided.

Prioritizing Intentions on the Margins: Effects of Marginally Higher Prioritization Strategies on Physical Activity Participation.

Previous research documented that "extremely high prioritization" strategies that involved allocation of all resources for time or energy on pursuing goals related to leisure-time physical activity and none of available resources on competing behavioral goals were optimal in terms of yielding highest levels of participation in physical activities. This study examined whether a "marginally higher prioritization" strategy that involved an intention to invest large but slightly more resources on physical activity than competing behaviors was optimal. In addition, we examined whether linear and quadratic models supported different conclusions about optimal prioritizations strategies. Response surface analyses of a quadratic model revealed that marginally higher prioritization was the most effective strategy. In addition, a linear regression model led us to incorrectly reject a "simultaneous goal pursuit" strategy in favor of an extremely high prioritization strategy. Findings suggest that prioritization strategies that "garner" low opportunity costs are the most optimal.

Application of the Transtheoretical Model to Physical Activity in Deaf Individuals.

The current study used the transtheoretical model (TTM) as a guiding theoretical framework to assess differences in processes of change, decisional balance, and self-efficacy among deaf individuals with different levels of physical activity. Overall, 146 participants (M age = 26.4 yr, SD = 4.28) completed anonymous questionnaires assessing the dimensions of the TTM, stages of change, processes of change, decisional balance, and self-efficacy. Analysis of variance showed that both experiential and behavioral processes of change were higher in the preparation, action, and maintenance stages than in the other stages. Accordingly, the benefits of physical activity participation were stronger in the preparation stage, whereas the costs were more evident in the precontemplation stage. Finally, self-efficacy at the preparation stage was higher than in the other stages. The findings revealed how different stages of physical activity participation can be explained through the TTM, and the implications for physical activity intervention are discussed.

Beliefs about the causes of success in sports and susceptibility for doping use in adolescent athletes.

The present study set out to assess the impact of attributional beliefs about success on the susceptibility for doping use in adolescent athletes. The sample consisted of 309 adolescent athletes participating in both team and individual sports. Participants completed a battery of questionnaires including Beliefs about the Causes of Success in Sport Questionnaire (BACSSQ), current and past doping use, and measures of attitudes, norms, situational temptation and social desirability. Variance reduction rate analysis revealed that social desirability did not act as a confounder in the relationship between doping susceptibility and its predictors. With regard to beliefs about the causes of success dimensions, only deception emerged as a significant predictor of doping use susceptibility over and above the effects of well-established social-cognitive predictors of doping intentions and use. These findings imply that beliefs about the causes of success in youth sports may comprise another dimension of risk factors for doping susceptibility and use.

Developmental relations of achievement goals and affect in physical education.

OBJECTIVE: This study aimed to examine the developmental relationships between achievement goals and affects in school physical education. METHOD: The study sample comprised 1063 (girls 546) Finnish Grade 6 students (M = 12.27 years ± .33 at the beginning of the study). The participants in the study were asked to provide annual assessments about their perceptions of achievement goals, enjoyment, and anxiety. The assessments were conducted four times over three consecutive years. RESULTS: The results indicated that mastery-approach goals were positively associated with enjoyment (between-level), whereas both mastery-avoidance and performance-avoidance goals were positively associated with anxiety (between-level). Additionally, the associations between repeated measures (within-level) of mastery-approach and enjoyment were similar each year, whereas mastery- and performance-approach/avoidance were consistently associated with anxiety within the same year. Girls reported lower performance-approach and enjoyment but higher mastery-avoidance and anxiety than boys. CONCLUSION: The findings suggest that mastery approach goals exhibit a positive correlation with favorable affective reactions, while performance-avoidance goals demonstrate a connection with maladaptive responses. Physical education teachers should endeavor to establish mastery-oriented goals for their students from the outset of the educational process.

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 personal and organisational factors that underpin intentions to blow the whistle or that may lead to engagement in whistleblowing behaviours in sport. Thirty-three competitive athletes across a range of sports took part in a semi-structured interview which sought to explore what they would do should they encounter a doping scenario. Content analysis revealed that whistleblowing is a dynamic process characterised by the interaction of a range of personal and organisational factors in determining the intention to report PED use. These factors included moral reasoning, a desire to keep the matter "in-house", perceived personal costs, institutional attitudes to doping, and social support. Analysis revealed a number of "intervening events", including a perceived lack of organisational protection (e.g., ethical leadership) within some sporting sub-cultures, which present an important obstacle to whistleblowing. The intention to report doping was underpinned by a "fairness-loyalty trade-off" which involved athletes choosing to adhere to either fairness norms (which relate to a sense that all people and groups are treated equally) or loyalty norms (which reflect preferential treatment towards an in-group) when deciding whether they would blow the whistle. The promotion of fairness norms that emphasise a group's collective interests might encourage athletes to view whistleblowing as a means of increasing group cohesiveness and effectiveness and thereby increase the likelihood of this practice.

Self-Affirmation and Image/Performance Enhancing Drug Use in Recreational Exercise.

Objectives: The use of image and performance enhancement drugs (IPEDs) in recreational sport represents an emerging public health and societal problem. The present study investigated whether self-affirmation changed exercisers' intentions to use IPEDs, via the effects of mental construal and message acceptance. Method: Sixty-eight exercisers who self-reported IPEDs use participated in the study and were randomly assigned to either a self-affirmation or a control group. All participants read a health-related message about the 10 consequences of IPEDs and subsequently completed a survey measuring message acceptance, mental construal, doping intentions and IPEDs-related social cognitive variables. Results: There were no significant differences between the self-affirmed and the control groups. Hierarchical linear regression analysis further showed that message acceptance, subjective norms, and situational temptation were significantly associated with intentions to use IPEDs. Conclusion: Our findings raise the possibility that for recreational exercisers IPED's use is seen mostly as a health-related matter than a socio-moral transgression.

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.

Are dietary supplement users more likely to dope than non-users?: A systematic review and meta-analysis.

In the past decade, a body of evidence has reported that dietary supplement use is related to prohibited performance enhancing substance use (i.e., doping). To help international and national sport organisations understand the degree to which dietary supplement use is related to doping, the objectives of this systematic review and meta-analysis were to 1) compare the prevalence of doping between dietary supplement users and non-users and 2) identify whether supplement use is related to doping social cognitive factors. We searched for studies sampling athletes and that measured both dietary supplement use and doping in EMBASE, MEDLINE, PsychINFO, CINAHL and SPORTDiscus from database creation to May 2022. Risk of bias was assessed using JBI Critical Appraisal Checklist for cross-sectional studies and the STROBE checklist. Twenty-six cross-sectional studies, involving 13,296 athletes were included. Random-effect models revealed that doping was 2.74 (95% CI=2.10 to 3.57) times more prevalent in dietary supplement users (pooled prevalence = 14.7%) than non-users (6.7%), and that users reported stronger doping intentions (r=0.26, 0.18 to 0.34) and attitudes (r=0.21, 0.13 to 0.28) compared to non-users. Preliminary evidence also suggests that dietary supplement users were less likely to dope if they were more task oriented and had a stronger sense of morality. Results of the review are limited by the cross-sectional design used in all studies and lack of consistency in measurement of dietary supplement use and doping. Data indicate that athletes using dietary supplements are more likely to self-report doping Anti-doping policy should, therefore, target dietary supplement use in anti-doping education programmes by providing alternative strategies for performance enhancement or highlighting the safest ways they can be consumed. Similarly, as a large proportion of athletes use dietary supplements without doping, further research is needed to understand the factors that protect a dietary supplement user from doping. No funding was received for the review. A study protocol can be found here: https://osf.io/xvcaq.

Context matters: athletes' perception of dopers' values, actions and vulnerabilities.

Background: Although 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. Methods: We recruited elite athletes from 13 countries representing 27 sports at a national or international level (N = 60) to participate as part of a larger research project. Data were collected via focus group interviews focusing on values, value priorities and perceptions about the role of values in doping as a phenomenon and in dopers' actions. Data were analysed using iterative thematic analysis. Results: Three themes were identified: (1) athletes' personal stance on doping, (2) dopers in the eyes of the anti-doping-compliant athletes, and (3) doping vulnerability is a balance. Athletes in this study strongly opposed doping but showed empathy and understanding toward athletes who doped under certain circumstances. Furthermore, athletes believed that "clean" and "doping" athletes are not always distinguished by the values they hold, leading to the realisation that all athletes can be vulnerable to doping at some point. This vulnerability is a balance between risks and protective factors in a complex interaction between environmental, personal, and situational influences. Each element (e.g., values, environment) can be a motivator or a barrier. Consequently, doping vulnerability is highly idiosyncratic and dynamic. Conclusion: If doping is not due to a lack of moral values but the consequences of combined risk factors that override the guiding function of values, then doping can happen to anyone, "good" athletes included. Developers and facilitators of anti-doping education programmes are advised to embrace this important aspect. The results also contribute to developing the doping vulnerability concept as a balance between risks and protective factors and draw attention to the clean athlete vulnerability, which is rooted in the combination of strategic performance enhancement via non-prohibited means, their exposure to anti-doping requirements and the constant high level of suspicion that surrounds them.

Method effects: the problem with negatively versus positively keyed items.

Using confirmatory factor analyses, we examined method effects on Rosenberg's Self-Esteem Scale (RSES; Rosenberg, 1965) in a sample of older European adults. Nine hundred forty nine community-dwelling adults 60 years of age or older from 5 European countries completed the RSES as well as measures of depression and life satisfaction. The 2 models that had an acceptable fit with the data included method effects. The method effects were associated with both positively and negatively worded items. Method effects models were invariant across gender and age, but not across countries. Both depression and life satisfaction predicted method effects. Individuals with higher depression scores and lower life satisfaction scores were more likely to endorse negatively phrased items.

Behaviours and Beliefs Related to Whistleblowing Against Doping in Sport: A Cross-National Study.

Background: Whistleblowing has been recognized as an important deterrent of doping in elite competitive sport. The present study examined athletes' knowledge of external whistleblowing channels and on how and where to report doping misconduct, perceived trust in different whistleblowing reporting channels, whistleblowing behaviour and athletes' reasons for reporting (or not) doping misconduct. Methods: Athletes from Greece (n = 480), the Russian Federation (n = 512) and the United Kingdom (n = 171) completed a structured questionnaire on demographics, knowledge of different whistleblowing channels, perceived trust in internal and external whistleblowing channels, past whistleblowing behaviour and reasons for reporting (or not) doping misconduct. Results: The British athletes reported greater awareness of whistleblowing reporting channels (e.g., WADA's Speak Up and IOC's reporting platform) than did athletes from Greece (all p < 0.001) and Russia (p = 0.07, and p = 0.012) respectively. However, British athletes reported the lowest scores on knowledge of how and where to report doping misconduct, as compared to athletes from Greece and Russia. The majority of respondents reported greater trust to their coach or a club manager than to other whistleblowing channels, however, responses regarding other channels varied by country. Among athletes who detected doping misconduct 62% of athletes did not report it, while 38% reported it. Reasons for and against reporting doping misconduct reflected in eight themes that were identified using thematic analysis. Conclusion: Athletes showed low awareness of external whistleblowing channels and they predominantly trusted internal whistleblowing channels. Sportspersonship, confidence in resources and personal benefits were among the reasons that facilitate reporting doping misconduct. The present findings indicate that cultural context may play a role in the ways athletes perceive whistleblowing, and this should be taken into account by future interventions to promote the reporting of doping misconduct.

Effects of a School-Based Intervention on Motivation for Out-of-School Physical Activity Participation.

Purpose: We tested the effects of an autonomy-supportive intervention in physical education (PE) on high-school students' autonomous motivation in PE, and their autonomous motivation, intentions, and physical activity (PA) behavior in a leisure time guided by the trans-contextual model. Method: PE classes in two schools were assigned to receive either an autonomy-supportive intervention and/or a control intervention via random allocation by the school. The PE teacher of the school assigned to the autonomy-supportive intervention was trained to provide autonomy support while the PE teacher of the school assigned to the control intervention received no training. Students (N = 256) in all classes completed measures of perceived teacher autonomy support, autonomous motivation in PE and leisure time, and beliefs, intentions, and PA in leisure time before and immediately after the intervention. Results: Results revealed direct effects of the autonomy-supportive intervention on changes in perceived autonomy support. However, there were no direct intervention effects on change in intentions and PA behavior. The intervention also had indirect effects on changes in autonomous motivation in PE and leisure time. Additionally, change in perceived autonomy support had direct effects on change in autonomous motivation in PE and indirect effects on change in leisure-time autonomous motivation. Changes in autonomous motivation in leisure time had direct effects on changes in beliefs and indirect effects on changes in intentions and PA behavior through changes in beliefs. Conclusion: The study provides valuable information on the effect of autonomous supportive climate on students' beliefs toward PA in PE lessons and in their leisure time outside of school.

The Effect of Moral Disengagement on Bullying: Testing the Moderating Role of Personal and Social Factors.

Bullying is a subset of aggressive behavior that has severe consequences in children's psychosocial development. Bullying behaviors can be influenced by personal and social factors, such as gender, age, school type, and sport participation, as well as psychological constructs, such as moral disengagement. The present study was designed to investigate the effect of moral disengagement on bullying behaviors and the moderating role of personal and social factors. In this study, 2,252 students (M = 13.57, SD = 1.17; 1,125 girls, and 1,127 boys) attending the sixth grade of primary school and secondary education have participated. Participants completed the revised Olweus Bully/Victim Questionnaire and Bandura's Moral Disengagement Questionnaire along with general questions about their demographic characteristics. The results of the analyses demonstrated moderation effects of gender on the moral disengagement-physical bullying relationship and of age on the moral disengagement-verbal bullying relationship. No significant moderating effect emerged for school type and sport participation. The findings of the present study provide valuable information about the role of personal and social factors on bullying behavior.
