The role of self-regulatory efficacy, moral disengagement and guilt on doping likelihood: A social cognitive theory perspective

A Psychological Intervention Reduces Doping Likelihood in Italian Athletes: A Replication and Extension

Research on doping prevention has proliferated in recent years as evidenced by the development of several anti-doping interventions. However, researchers have rarely examined whether an anti-doping intervention delivered and evaluated in one population is similarly effective in a different population. The purpose of our research was to determine whether the psychological intervention developed by Kavussanu et al. (2022) and originally delivered in British and Greek athletes, was equally effective as the standard educational intervention in preventing doping (i.e., by influencing our primary and secondary outcomes) in young Italian athletes. Eligible participants were identified via a screening survey administered to 540 athletes from 46 clubs in Italy. A total of 15 sport clubs (121 athletes; 16.95% female; aged 18.52 ± 2.15 years) were assigned to one of three conditions: a psychological intervention, an educational intervention, or a no-intervention control group. Each intervention consisted of six one-hour sessions delivered to small groups of athletes over six weeks. Athletes completed measures of doping likelihood, anticipated guilt, moral disengagement, and self-regulatory efficacy pre-intervention, post-intervention, and two months later. Control group participants completed the same measures at the same time points. The two interventions were similarly effective in reducing doping likelihood and increasing anticipated guilt from pre to post, while the control group showed no change; these effects were maintained at follow up. Both interventions reduced moral disengagement and increased self-regulatory efficacy from pre to post relative to the control group, and these effects were maintained at follow-up. In conclusion, our study broadly replicates previous findings and highlight the need for anti-doping organisations to target psychological variables and doping-relevant information in anti-doping education.

Perceived Coach-Created Empowering and Disempowering Climate Effects on Athletes' Intentions to Use Doping: The Mediational Role of Self-Regulatory Efficacy and Attitudes towards Doping

BACKGROUND

The purpose of this study was to examine the relationship between perceived coach-created empowering and disempowering motivational climate and doping likelihood among athletes and whether the attitudes towards doping and doping self-regulatory efficacy mediates these relationships.

METHODS

Athletes (N = 948; 50% male; mean age, 20.32, SD = 2.45) recruited from a variety of sports completed questionnaires assessing their perceptions of coach-created motivational climate, attitudes towards doping, doping self-regulatory efficacy, and doping likelihood.

RESULTS

The study's results showed significant negative direct effects of a perceived empowering climate on doping likelihood (β = -0.50) and attitudes towards doping (β = -0.48), and a positive effect on self-regulatory efficacy (β = 0.48). On the contrary, a disempowering climate had positive direct effects on doping likelihood (β = 0.53) and attitudes towards doping (β = 0.45), and a negative effect on self-regulatory efficacy (β = -0.49). Significant indirect effects on doping likelihood via attitudes and self-regulatory efficacy were found.

CONCLUSIONS

Our findings suggest that athletes who perceive a more empowering climate created by the coach are less likely to use banned substances due to their more negative attitudes towards doping and stronger belief in their ability to resist the temptation to use doping.

Morality- and Norm-Based Subgroups of Disability-Sport Athletes Differ on Their Anticipated Guilt and Intentions Toward Doping

The purpose of this study was to examine whether subgroups of disability-sport athletes exist on morality- and norm-based doping cognitions and whether these groups differ in anticipated guilt or doping intentions. A survey was completed by 186 athletes (Mage = 37.5 years, 78.0% male, 45.1% wheelchair basketball) assessing norms, doping moral disengagement, anticipated guilt, and intentions to dope. Cluster analysis revealed four distinct subgroups of athletes, including one potentially high-risk subgroup characterized by relatively high scores on doping moral disengagement, subjective norms, and descriptive norms. One-way analysis of variance revealed significantly lower anticipated guilt in two athlete subgroups characterized by relatively higher doping moral disengagement than the other two subgroups. Moreover, the potentially high-risk group had a greater proportion of athletes showing some presence of intention to dope. This study suggests there is a small subgroup of disability-sport athletes at elevated risk of doping who might benefit from targeted antidoping interventions.

"I RUN CLEAN Project"-An Innovative and Self-Sustainable Approach to Develop Clean Sport Behaviours in Grassroots Athletes

The phenomenon of doping is a public health issue that poses threats to sport and society. In recent decades, the emphasis on efforts to address the issue and reduce the incidence of doping by young people in sport has shifted from deterrence through testing and punishment to the promotion of clean sport behaviours through values-based education. The "I Run Clean project" sought to develop new and effective tools targeting grassroots athletes and those around them (coaches, medical support personnel, sport leaders, parents). These included sport-specific e-learning and in-person peer-to-peer workshops led by trained volunteer ambassadors. The aim of all "I Run Clean" measures is to go beyond the warnings and provision of factual information about early anti-doping campaigns to a more holistic educational approach that focuses participants on their personal and sport-related values in order to encourage good decision-making and resistance to doping-related behaviours. This study evaluates the efficacy of the peer-to-peer workshops and their impact on selected psycho-social variables. The collaboration of the volunteer ambassadors is shown to effectively transmit the desired reasoning, reduce doping risk factors and enhance protective factors.

The meta-cognitive role of thought morality in attitude change and behavioural intentions related to doping

Prior research has examined the relationships between morality, attitudes, and intentions related to doping predominantly via correlational studies based on the theoretical frameworks provided by extensions to the theory of planned behaviour, and the social cognitive theory of moral thought and action. In contrast, the present study experimentally analysed a psychological process (i.e., self-validation) through which thought morality can influence attitudes and intentions. Two hundred and forty-two participants (122 males and 120 females) were randomly assigned to read a message either against or in favour of legalising several doping behaviours in sports, then listed their thoughts regarding that proposal. Next, they were randomly assigned to perceive their thoughts as either moral or immoral, then indicated the extent to which they considered their thoughts as valid. Finally, participants reported their attitudes and intentions regarding the legalisation proposal. As hypothesised, the anti-legalisation (vs. pro-legalisation) message produced more unfavourable thoughts and attitudes, as well as lower intentions to support the legalisation proposal and engage in banned behaviours if legalised in sport. Most importantly, the effects of message direction on attitudes and intentions were greater for participants in the moral (vs. immoral) thought condition. Furthermore, changes in attitudes were consistent with a self-validation process.

Examining mindfulness and moral disengagement in doping: Perspective of Turkish wrestlers

Introduction

Studies related to attitudes toward the use of prohibited substances in Turkish athletes are scarce. The World Anti-Doping Agency (WADA) has implemented anti-doping educational policies emphasizing doping-related education in studies conducted among Turkish wrestlers. However, it is still unclear the extent to which the wrestlers comply and adhere to these anti-doping policies. No research has previously examined the effect of anti-doping education on athletes' mindfulness and moral disengagement in doping (MDD). Therefore, the present study has a two-fold objective: first, to examine whether doping-related education (DRE) and the status of being a national athlete (NA) have an effect on athlete mindfulness and MDD. Second, to analyze the relationship between each sub-dimensions of athlete mindfulness: awareness (ASD), judgment (JSD), and refocus (RSD) with MDD.

Methods

A total of 409 male wrestlers participated in this study. MANOVA analysis showed that NA and DRE alone have no effect on MDD but have a general effect on mindfulness.

Results

The highest effect was on the ASD of being an NA (ηp2 = 0.173). When the interaction effect of NA*DRE was examined, significant difference in MDD (F = 8.218, p = 0.004), ASD (F = 8.476, p = 0.004), JSD (F = 5.844, p = 0.016), and RSD (F = 11.476, p = 0.001) were found. MDD has a weak negative relationship with ASD (r = −0.126) and RSD (r = −0.041) and a weak positive relationship with the JSD sub-dimension (r = 0.140). Those results suggest that being a NA and having received anti-doping education affect moral disengagement in doping and athletes' mindfulness.

Discussion

As a conclusion, it is recommended to increase awareness and anti-doping education among national-standard Turkish wrestlers to prevent them from engaging in doping behaviors.

Adaptation and Validation of the Lithuanian Version of the Sport-Specific Doping Self-Regulatory Efficacy Scale

BACKGROUND

Use of banned performance enhancing substances in sport is one of the most widely recognized anti-doping rules violation. Research evidence suggests that self-regulatory efficiency is one of the key psychosocial processes related with doping. Therefore, aiming to generate more insights on the self-regulatory efficacy, sport-specific doping self-regulatory efficacy scale was proposed. The aim of the present study was to adapt and validate the Lithuanian version of the sport-specific doping self-regulatory efficacy scale.

MATERIAL AND METHODS

The scale construct validity and reliability was tested using a sample of 453 athletes (mean age 20.37, SD = 2.29; 46% male). Structural validity was assessed by exploratory and confirmatory factor analyses, convergent and discriminant validity of the scale were evaluated by assessing average variance extracted and also via correlational analyses. Cronbach's alpha and composite reliability values were used for reliability analysis.

RESULTS

Exploratory and confirmatory factor analyses confirmed the one factor structure of the sport-specific doping self-regulatory efficacy scale. The results also indicated that the scale had sufficient convergent and discriminant validity. The results showed an excellent level of internal consistency.

CONCLUSIONS

This study makes a contribution by confirming the validity and reliability of the Lithuanian version of the sport-specific doping self-regulatory efficacy scale.

Study of an Anti-Doping Education Program in Spanish Sports Sciences Students

Doping continues to be one of the biggest risks to the credibility of elite sports, and its practice remains widespread among athletes despite improved controls. Athletes' support personnel could be key to preventing doping behavior. In this sense, anti-doping education for this population appears as a possible strategy to reduce doping behaviors in elite sport, but these programs must be evaluated and designed based on scientific evidence. The aim of this research is to explore the impact of an anti-doping education program about substances perceived efficacy, ill-health short- and long-term effects, and the morality of doping substance use in Spanish sports sciences students.

METHOD

A total of 145 students of Physical Activity and Sport Sciences (PASS) from different Spanish universities who took an online anti-doping educational course of the Spanish Anti-Doping Commission (CELAD) answered a questionnaire on their perceptions about doping before, after, and four months later.

RESULTS

The results show that the course reduced students' ignorance about the effects of substances on performance and health and increased their moral judgment and feelings against doping.

DISCUSSION

The results are in line with previous research that showed that the moral stance against doping can be improved through educational programs.

CONCLUSION

Online educational interventions can be effective in reducing doping behavior, so their future implementation among ASP can be an effective strategy to reduce doping behavior.

Effectiveness of the world anti-doping agency's e-learning programme for anti-doping education on knowledge of, explicit and implicit attitudes towards, and likelihood of doping among Chinese college athletes and non-athletes

Background

This study aimed to evaluate the effects of the World Anti-Doping Agency's e-learning programme for anti-doping education on knowledge of, explicit and implicit attitudes towards, and likelihood of doping among Chinese college athletes and non-athletes.

Method

Thirty-two young adults (including 16 college athletes) were recruited to receive the Athlete Learning Program about Health and Anti-Doping (ALPHA) intervention (Zh-hans version). Another 32 young adults were recruited for no-treatment control purposes. Before and immediately after the intervention, the ALPHA test, performance enhancement attitude scale, doping likelihood scale, and brief implicit association test (BIAT) were performed. Cortical activity during the BIAT test was monitored using a functional near-infrared spectroscopy instrument.

Results

Significant intervention effects were observed for knowledge (p < 0.01, η² = 0.21) and explicit attitude (p < 0.05, η² = 0.12) but not for doping likelihood (p > 0.05; benefit situation: η² = 0.04; cost situation: η² = 0.02). Compared with the non-athletes, the college athletes reported lower doping likelihood scores in benefit situations (e.g., financial gain, p < 0.05, η² = 0.10). Regarding the BIAT task, the experimental effect was successfully induced by different semantic associations between the concepts and the attitude (doping + like vs. doping + dislike). The mean reaction times (p < 0.01, η² = 0.36) and error rate (p < 0.01, η² = 0.34) in the doping-like block were higher than those in the doping-dislike block. Moreover, oxygenated haemoglobin (oxy-Hb) in response to BIAT interference in the temporoparietal junction-related channels was increased during the post-intervention test (p < 0.05, η² varied from 0.09 to 0.16).

Conclusions

The findings suggest that the online anti-doping education programme is partially effective among Chinese college athletes and non-athletes. Furthermore, our findings reflect enhanced cognitive control after the education intervention to suppress a prepotent implicit attitude towards doping.

Conspiracy beliefs, regulatory self-efficacy and compliance with COVID-19 health-related behaviors: The mediating role of moral disengagement

Although recent studies on the 2019 coronavirus disease (COVID-19) have highlighted the negative effects of moral disengagement on intentions to comply with COVID-19 containment measures, little is known about the mediating role of moral disengagement in the relationship between regulatory self-efficacy in complying with the containment measures, beliefs in conspiracy theories and compliance with COVID-19 health-related behaviors. Data were collected from 1164 young adults (women, N = 796; 68.4%; mean age 25.60 ± 4.40 years) who completed an online survey from 15th May to 22nd June 2021. Results of the multi-group path analyses indicated that higher beliefs in conspiracy theories were associated with lower compliance with COVID-19 health-related behaviors, whereas higher self-efficacy beliefs in complying with the containment measures were associated with higher compliance with COVID-19 health-related behaviors. Moral disengagement significantly mediated the associations between beliefs in conspiracy theories, regulatory self-efficacy, and compliance with COVID-19 health-related behaviors. Finally, the tested model was gender-invariant. Findings suggest that public health authorities and social care professionals should promote interventions aimed at improving regulatory self-efficacy, emphasizing the moral significance of respecting or ignoring the recommended COVID-19 measures (e.g., physical distance in public), and enhancing people's concern for the potential harms of their immoral actions.

Answering the call for values-based anti-doping education—An evidence-informed intervention for elite adolescent athletes in Germany and Austria

Doping has serious negative consequences for athletes and the integrity of sports, implying the need for effective prevention programs. Since educating young athletes about doping-related knowledge is deemed to be not sufficiently effective to minimize doping, a focus on values, emotions and morality is seen as a promising approach and previous research indicates which variables exactly could be addressed in anti-doping efforts. These variables are anticipated guilt, empathy, moral disengagement, and collective moral norms, since these constructs have been strongly and consistently linked to doping intention, likelihood, or behavior. Therefore, the purpose of this study was to develop a values-based anti-doping intervention, which targets the aforementioned variables, and to evaluate its effectiveness in producing changes in outcomes in comparison to an information-based intervention and a waiting control group. To evaluate their effectiveness, both interventions, which each consist of six 45-min sessions (one session per week) were implemented in a sample of 321 young elite athletes, aged 13–19 years, from a broad range of team and individual sports. Thirty different teams, training groups or classes were randomly assigned to either the values-based intervention, the information-based intervention, or to a waiting control group. Doping intention, doping susceptibility as well as the above mentioned variables were assessed at pre- and posttest and, for participants of the values- and information-based conditions also at a 3 to 4-month follow up. Within a multilevel modeling framework general linear mixed regression analyses revealed that the values-based intervention, compared to the control group, was able to decrease athletes' moral disengagement and increase their anticipated guilt immediately after the intervention (at posttest), whereas no effects for the information-based intervention emerged. Looking at how the outcomes developed over time (i.e., at the follow up measurement), it could be demonstrated that the reduction in moral disengagement sustained. The increase in anticipated guilt, however, was not sustainable and, surprisingly, decreased from post to follow up. Furthermore, athletes in the values-based intervention reported higher empathy from post to follow up, which could possibly indicate a “delayed” effect. This study provides support that a values-based approach can produce changes in some, yet, not all addressed variables and specific elements from this intervention could potentially be a useful addition to traditional anti-doping education (i.e., information provision).

Intentions to Steal and the Commitment Problem. The Role of Moral Emotions and Self-Serving Justifications

This study focuses on determinants underlying young persons" self-reported intentions to steal a small amount of money. From an evolutionary standpoint, theft is a frequency-dependent strategy that may have been favored because it gave individuals a reproductively-relevant advantage in the competition for scarce resources. Although human groups do not tolerate the act of stealing, theft is still very common. Our study is rooted in Robert Frank's theory of the moral commitment problem. Moral emotions such as anticipated guilt are devices designed by evolutionary forces to motivate cooperative behavior in situations entailing a commitment problem. However, the anticipation of guilt feelings can be circumvented by self-serving justifications, therefore increasing the likelihood to steal. A large region-wide sample of adolescents (N = 3694) is used to analyze whether anticipated moral guilt and self-serving justifications mediate the effects of empathy, fear sensitivity, and perceived peer disapproval in their relationship to intentions to steal. Several propositions are tested in a latent variable model within the framework of SEM. Visual scenarios depicting an opportunity to take a small amount of money from a stranger are used to elicit participants" self-reported intentions to steal. Results suggest that empathic concern and empathic perspective-taking, perceived peer disapproval, and fear sensitivity affect the likelihood of theft by influencing anticipated guilt and self-serving justifications that, in turn, respectively reduce and promote the likelihood of theft.

Moral Disengagement in Youth Athletes: A Narrative Review

The sports environment can be considered as a context characterized by interactions typical of social groups, where children have the chance to learn good values. Positive and negative behaviours in sports, also called prosocial and antisocial behaviours, have been studied according to a moral perspective, as has doping behaviour, taking into consideration the concept of moral disengagement. Moral disengagement in children has been associated with maladaptive behaviours later in life, even though it should disappear with growth. Concerning the sports environment, previous reviews on the topic have extensively illustrated the role of moral variables in sport and their relation to antisocial behaviour and doping, positing some research questions that should be investigated in the future. Starting from these questions, the current narrative review aims to update literature about the effects of moral disengagement on youth athletes. Therefore, new studies about the predictors of moral disengagement are introduced, followed by contributions concerning the relationship between moral disengagement and doping and between moral disengagement and antisocial behaviour. Finally, the review summarizes which research questions have been solved in the last decade and which should be researched further on.

Moral Disengagement, Social Norms, and Motivational Profiles Influence Attitudes Toward Doping Among Spanish Athletics Coaches

Coaches strongly influence athletes' attitudes toward doping and can shape athlete's beliefs, behaviors, and decisions to be for or against doping. Coached-centered studies examining multiple factors affecting coaches' doping attitudes and behavior are scarce. The aim of this study was to analyze for the first-time attitudes toward doping in athletics coaches using the Sport Drug Control Model (SDCM) as a theoretical framework. A secondary aim was to determine the factors in the model predicting attitude and susceptibility toward doping. A cross-sectional study was carried out using a sample consisting of 201 Spanish athletics competitive level coaches from whom 11.4% were female. Participants completed a cross-sectional online survey. Structural equation modeling showed a good fitness of the SDCM. Positive attitudes toward doping predicted high susceptibility to doping (β = 0.39, p < 0.001). Moral disengagement (β = 0.58, p < 0.001), descriptive norms (β = 0.42, p = 0.001), ego-oriented goals (β = 0.34, p < 0.05), and self-efficacy to refrain from doping (β = 0.26, p < 0.05) displayed a significant influence on attitudes toward doping. Self-reported doping prevalence in coaches was 4.5%. These variables should be considered when designing anti-doping research projects and educational programs aiming at modifying coaches' attitudes toward doping. It is recommended to focus more efforts on coaches, without putting aside the athletes, and therefore turn coaches into reliable doping prevention factors. To this end, it is necessary to enhance scientific research and then develop, implement, and promote more educational programs targeting coaches, on a mandatory basis while covering the specific needs of coaches so that they can perform their role as anti-doping educators in an effective, committed, and proactive manner.

Moral Identity and Attitudes towards Doping in Sport: Whether Perception of Fair Play Matters

Research evidence suggests that athletes' attitudes towards banned substances are among the strongest predictors of intention to use or actual practice of doping. Previous research has found that personal morality was negatively related to doping attitudes. However, less is known about the role of athletes' perceptions of fair play on their attitudes towards doping. First, we examined whether moral identity was associated with athletes' attitudes towards doping and whether their perceptions of fair play mediated this relationship. The second purpose was to determine whether these associations differed among non-athletes. Overall, 365 university students (49.9% males, 55.3% athletes) participated in this study (mean age 22.02, SD = 6.58). They completed questionnaires measuring the aforementioned variables. The results showed that athletes' moral identity and endorsement of fair play were negatively associated with their attitudes towards doping. The mediation analyses showed that the effect of moral identity on attitudes towards doping was partially mediated by perceptions of fair play (indirect effect, β = -0.10, p < 0.05). Unlike student athletes, non-athletes' moral identity negatively predicted attitudes towards doping only indirectly, via fair play perception (indirect effect, β = -0.08, p < 0.05). The study provides insights into how a person's morality and perception of moral values in sport may act as factors related to doping in sport. The practical implications for the promotion of anti-doping attitudes for athletes and separately for student non-athletes were provided together with future research perspectives.

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.

Perceived Motivational Climates and Doping Intention in Adolescent Athletes: The Mediating Role of Moral Disengagement and Sportspersonship

Doping is an important issue in competitive sports and poses potentially irreversible consequences to athletes. Understanding the psychological process underlying antecedents and doping intention will inform policy and prevention. This study aimed to test the psychosocial mechanisms of doping in adolescent athletes using an integrated model. In this model, we examined the associations of perceived motivational climate (i.e., task-involving and ego-involving), moral variables (i.e., moral disengagement and sportspersonship), and attitudinal variables (i.e., perceived pros/cons of doping and perceived cons of not doping) with doping intention. We further investigated whether the moral variables mediated the relationship between perceived motivational climate and doping intention. A cross-sectional survey was employed in the present study. Six hundred and fifteen Chinese adolescent athletes (mean age = 15.68 ± 1.67 years) completed questionnaires measuring demographic information and the variables mentioned previously. Structural equation modeling showed that the hypothesized model had a good fit and explained 64.1% of the variance in doping intention. Task-involving motivational climate indicated both directly and indirectly negative associations with doping intention via sportspersonship. The ego-involving motivational climate was positively associated with doping intention via moral disengagement. Among perceived pros/cons of doping and perceived cons of not doping, both perceived cons of doping and cons of not doping were positively associated with doping intention with a small effect size. This study confirmed the roles of tasking- and ego-involving motivational climates, moral variables, and attitudinal variables on doping intention. These research findings may provide new insights for the future of intention-based doping prevention programmes.

A Multistudy Cross-Sectional and Experimental Examination Into the Interactive Effects of Moral Identity and Moral Disengagement on Doping

Moral identity and moral disengagement have been linked with doping likelihood. However, experiments testing the temporal direction of these relationships are absent. The authors conducted one cross-sectional and two experimental studies investigating the conjunctive effects of moral identity and moral disengagement on doping likelihood (or intention). Dispositional moral identity was inversely (marginally), and doping moral disengagement, positively, associated with doping intention (Study 1). Manipulating situations to amplify opportunities for moral disengagement increased doping likelihood via anticipated guilt (Study 2). Moreover, dispositional moral identity (Study 2) and inducing moral identity (Study 3) were linked with lower doping likelihood and attenuated the relationship between doping moral disengagement and doping likelihood. However, the suppressing effect of moral identity on doping likelihood was overridden when opportunities for moral disengagement were amplified. These findings support multifaceted antidoping efforts, which include simultaneously enhancing athlete moral identity and personal responsibility alongside reducing social opportunities for moral disengagement.

Testing the validity and reliability of the doping willingness in sport scale

Although research investigating doping in sport is burgeoning, there is still a lack of proxy measures of doping behavior that have undergone extensive psychometric testing. To address this issue, we modified a previously used measure of doping willingness in sport and tested aspects of validity and reliability across four studies. In Study 1, we provided support for the face and content validity of the items, and then found support for the factor structure of the scale in a sample of athletes (N = 205) using confirmatory factor analysis. In Study 2, we collected data from an independent sample of athletes (N = 236) to provide further evidence for the factor structure of the scale using confirmatory factor analysis as well as provided evidence for concurrent and discriminant validity. In Study 3, a further independent sample of athletes (N = 144) completed the scale and provided support for discriminant and predictive validity of the scale. In Study 4, we collected data from a further independent sample (N = 74) to provide support for the test-retest reliability, and stability of items. Lastly, a confirmatory factor analysis was conducted on the samples across Studies 3 and 4, and the composite sample across all four studies which provided further support for the factor structure of the final 8-item scale. Taken together, these findings provide psychometric support for the scale to be used to measure the willingness of athletes to use banned substances to help facilitate future research investigating doping in sport.

Self-efficacy Mediates Perceived Benefits and Barriers of Adherence of Heroin-dependent Patients to Methadone for Addiction Treatment: A Health Belief Model Study

OBJECTIVE

Although methadone for addiction treatment (MAT) has been widely used in China, the low adherence rate in MAT clinics poses a great challenge. We aimed to investigate the factors related to the adherence of heroin-dependent patients to MAT based on the Health Belief Model (HBM) in Sichuan, China.

METHODS

A cross-sectional structured interview was conducted between August and November 2018. Stratified multi-stage sampling was carried out. A total of 581 participants were enrolled from 5 clinics and completed the face-to-face structured interview. Univariate, adjusted logistic regression, multivariate logistic regression analysis and the structural equation modeling (SEM) were employed to explore the association between constructs of HBM and adherence to MAT among heroin-dependent patients.

RESULTS

The adherence rate of MAT was 79.3% in the past 6 months. Among all constructs of HBM, self-efficacy (AOR: 1.16, 95% CI: 1.10, 1.22), perceived benefits (AOR: 1.05, 95% CI: 1.00, 1.10) and perceived barriers (AOR: 0.87, 95% CI: 0.77, 0.98) were associated with adherence to MAT. Self-efficacy was directly associated with adherence to MAT (β = 0.347, P < 0.05). Perceive benefits (β = 0.276, P < 0.01) and perceived barriers (β = -0.241, P < 0.05) were directly associated with self-efficacy. However, perceived benefits (β = 0.096, P < 0.01) and perceived barriers (β = -0.084, P < 0.01) were only indirectly associated with adherence to MAT.

CONCLUSION

The adherence of heroin-dependent patients to MAT can be explained by self-efficacy, perceived benefits and barriers. Self-efficacy plays a significant role as a mediating variable. Future interventions should be considered to improve patients' self-efficacy to MAT.

Validation of employees' self-leadership using exploratory and confirmatory factor analysis

Purpose

Self-leadership (SL) involves the strategic management of people's perceptions and behaviours to enable them to set directions, identify their needs and work effectively. Here, an instrument was developed to measure SL of employees, organisations and managers in Thailand context.

Design/methodology/approach

Questions were developed for a questionnaire based on concepts and theories and validated using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) along four performance dimensions. Research samples were employees in the accommodation industry in Thailand. Factor analysis results confirmed the questionnaire as a reliable SL instrument with acceptable composite reliability (CR), average variance extracted (AVE) and convergent and discriminant validity.

Findings

Four factors of SL were identified as self-visualising and goal setting, self-reward and positive thinking, self-observation and cueing and self-talking and evaluating beliefs comprising 21 items. Factor analysis confirmed the validity of the questionnaire as a reliable SL tool as evidenced by a CR of 0.811 and AVE of 0.526 with acceptable convergent and discriminant validity criteria.

Research limitations/implications

Results were limited to a single group sample of accommodation and cross-sectional design and should be carefully considered for application in different situations.

Practical implications

Findings regarding the four performance dimensions suggest that this SL scale questionnaire can be applied to different businesses and settings either as is or with slight modifications.

Originality/value

Our SL scale is novel and serves as an excellent instrument to measure the behavioural perception of employees.

Ego involvement increases doping likelihood

Achievement goal theory provides a framework to help understand how individuals behave in achievement contexts, such as sport. Evidence concerning the role of motivation in the decision to use banned performance enhancing substances (i.e., doping) is equivocal on this issue. The extant literature shows that dispositional goal orientation has been weakly and inconsistently associated with doping intention and use. It is possible that goal involvement, which describes the situational motivational state, is a stronger determinant of doping intention. Accordingly, the current study used an experimental design to examine the effects of goal involvement, manipulated using direct instructions and reflective writing, on doping likelihood in hypothetical situations in college athletes. The ego-involving goal increased doping likelihood compared to no goal and a task-involving goal. The present findings provide the first evidence that ego involvement can sway the decision to use doping to improve athletic performance.

Moral behavior in sport

In this review paper, we provide an overview of recent research on prosocial and antisocial behaviors, in the context of sport, focusing mainly on antecedents and consequences of these behaviors. Motivational variables such as task orientation, mastery climate, autonomous motivation, and autonomy supportive climate are likely to promote prosocial behavior, whereas ego orientation, performance climate, controlled motivation, and controlling climate may lead to antisocial behavior. The effects of some motivational variables (i.e., controlled motivation and controlling climate) on antisocial behavior may be mediated by moral disengagement, which has been consistently linked to antisocial behavior across a number of studies. Two moral variables, moral identity and empathy have been found to inhibit antisocial behavior, and their effects are due to anticipated guilt for acting antisocially. With respect to consequences of teammate behavior, some evidence suggests that prosocial behavior may enhance the recipient's enjoyment, effort, commitment, and performance, whereas antisocial behavior could lead to anger. Finally, the frequency of prosocial and antisocial behaviors varies as a function of context: Student athletes display more antisocial behavior towards their opponents compared to their fellow students but also more prosocial behavior towards their teammates than towards their fellow students. In sum, both motivational and moral variables predict prosocial and antisocial behaviors in sport, and these behaviors can have important consequences for the recipient.
