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.

Barriers and enablers in doping, anti-doping, and clean sport: A qualitative meta-synthesis informed by the theoretical domains framework and COM-B model.

To protect the integrity of sport, and the health of athletes, global anti-doping programmes seek to prevent doping, and elicit anti-doping and clean sport behaviours, through education, deterrence, detection, enforcement, and rules. To guide programme development, this meta-synthesis of qualitative research applied a behavioural science framework to identify barriers and enablers to doping, anti-doping, and clean sport. A systematic search of electronic databases up to May 2022, followed by critical appraisal, resulted in 73 included articles. Fifty-two articles reported the athlete perspective, thirteen included athletes, athlete support personnel (ASP), and other experts, and eight focused on ASP only. Rigorous methods of thematic synthesis were drawn upon to construct analytical themes in line with the theoretical domains framework (TDF) and the capability, opportunity, and motivation model of behaviour (COM-B). A wide range of barriers and enablers were identified which influenced capability, opportunity, and motivation to participate in a clean sport environment. The weight of evidence pointed to limitations in the current anti-doping education system in providing athletes and ASP with the knowledge and skills to protect against doping, as well as the significant influence of social and cultural norms in shaping doping and clean sport behaviours through a shared social identity, and risky contexts leading to moments of vulnerability to doping. We identified a need for anti-doping programmes to move beyond the current focus on athlete capability, and address the opportunity and motivation components of clean sport behaviours through a targeted and tailored focus on education, training, persuasion, modelling and environmental restructuring interventions.

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.

Measuring sport fantasy proneness and deflated reality in sport and performance: Development and validation of two context-specific instruments.

Fantasy-prone personalities and generalized states of pessimism and hopelessness have been linked to various behavioural, cognitive, and health related outcomes in the general population. Nevertheless, to date, knowledge of sport-specific fantasy proneness and athletes' perception of deflated reality in sport is scarce, possibly due to a lack of appropriate psychometric instruments to examine these two important context-specific constructs. In this research, we developed the Sport Fantasy Proneness Scale (SFPS) and the Deflated Reality in Sport Scale (DRSS), first assessing the content validity of items for the instruments following a rigorous process. Through two cross-sectional samples (Study 1: Sample 1 N = 255, Sample 2 N = 260) and one longitudinal sample (Study 2: Sample 3 N = 118) of competitive athletes in the UK, we then examined factorial, convergent, discriminant, and concurrent validity and measurement invariance (Study 1), as well as internal consistency, and test-retest reliability (Study 2) of the two new scales. Results revealed robust construct validity and reliability of scores on the two instruments and suggested very good invariance when implementing the new scales to athletes from different sports and competitive levels and good invariance for cross-gender comparisons. The new scales fill a gap in the sport psychology literature and provide researchers and practitioners with robust psychometric instruments to examine new research questions and tackle issues relevant to athletes' sport-specific fantasy proneness and perceptions of deflated reality.

Doping in Paralympic sport: perceptions, responsibility and anti-doping education experiences from the perspective of Paralympic athletes and parasport coaches.

Introduction: Limited effort has been invested in understanding doping in Paralympic sport. The limited evidence that exists suggests that factors influencing doping in parasport are similar to Olympic sport. However, based on the design and nature of the previous studies, where methods have been mostly limited to qualitative data and prevalence numbers, further research is warranted to extend previous findings. Methods: Informed by current evidence from Paralympic and Olympic sport, we aimed to investigate (1) para-athletes' perceptions of Anti-Doping Rule Violations (ADRVs) and responsibility for them, (2) descriptive norms for doping in parasport (3) perceptions of anti-doping education and legitimacy of anti-doping authorities, and (4) coach engagement in doping prevention and levels of doping confrontation efficacy using a quantitative survey approach. Results: In total, valid survey responses from 126 Paralympic athletes and 35 coaches from four countries (Germany, Austria, Switzerland, UK) were analysed for experience with anti-doping, descriptive norms, anti-doping education, perceived legitimacy, knowledge, and doping confrontation efficacy (coaches only). Across both athletes and coaches, the level of education was generally good and doping willingness was low. Classification cheating was considered a form of doping and seems to be an important issue for athletes and coaches, especially within the UK sample. For 33.3% of the athletes, doping control was their first experience with anti-doping. Coaches' engagement with doping prevention activities and their perceived efficacy to confront doping-related matters appears to be higher compared to Olympic coaches' samples. Discussion: Sport organisations/NADOs in Paralympic sport could use synergies with those organisations in Olympic sport, adopting similar approaches to anti-doping education, also focusing on a balanced communication of doping prevalence numbers and testing figures. Efforts to ensure athletes are educated about anti-doping before they are tested should be upheld. It seems that in para sport, different compared to able-bodied coaches, anti-doping organizations do not have to convince the coaches about their roles (i.e., being responsible for anti-doping education) anymore but can directly build on these resources. Overall, it seems that there are few differences between parasport and able-bodied sports and thus responsible organisations could use the existing programmes in Olympic sport and only adapt special content (e.g., boosting) which is unique to Paralympic athletes.

Systems mapping to understand complexity in the association between image and performance enhancing drugs (IPEDs) and harm.

BACKGROUND: Effective harm reduction work is needed to prevent and respond to the harms associated with image and performance enhancing drug (IPED) use and the diverse needs of IPED communities. Methods based around understanding and mapping complex systems have previously been applied to advance thinking on a range of complex health issues. We applied a systems perspective to explore factors that contribute to IPED-related harms in the UK and to identify harm reduction priorities. METHODS: An illustrative systems map was developed based on methods for mapping complex systems with expert stakeholders. Participants in two online workshops debated the important factors contributing to harm amongst people who use IPEDs and helped to refine and clarify the map. Discussions using the map reflected on where in the system intervention is needed and the policy implications. RESULTS: Stakeholders (n=18) identified 51 distinct factors as being important determinants of IPEDs-related harms, and the connections between them. These were grouped under nine domains that formed this system: identity, cognitive processes, beliefs about risk and harm, health and wellbeing, social environment, beliefs about healthcare, healthcare providers, interventions, and IPED markets. Four harm reduction priorities identified through reflexive discussion included providing a wider range of interventions, improving engagement between the IPED communities and healthcare professionals, new approaches to disseminating information in the community, and early intervention. CONCLUSION: Systems mapping methods are a useful approach to engage stakeholders to discuss drug use issues. A comprehensive policy response is required to this complex issue that recognises diversity in IPEDs communities, their decision-making, and their intervention and service needs, as current approaches are failing to adequately address important areas of harm. Engaging with a wide range of stakeholders is critical to generate new insights that can help respond effectively to reduce the risk of health harms.

The Meaning of "Clean" in Anti-doping Education and Decision Making: Moving Toward Integrity and Conceptual Clarity.

With the World Anti-Doping Agency's International Standard for Education (ISE) coming into effect in 2021, the clean-sport movement is at a pivotal stage. Through this conceptual paper we juxtapose the sector-wide anti-doping education as set out in the ISE on the decision-making process at the individual level. We discuss three critical issues for the clean-sport movement. First, we make the case for doping being a "wicked" problem and outline the possible implications of this for prevention and detection. Second, we consider why we need to address regulative, normative, and cognitive components of clean sport if we are to maximize its legitimacy. Third, we critically expose the fluidity with which clean sport is defined, and the implications of defining clean sport in substance- vs. rule-based terms, which, respectively, lead to theorizing clean sport as "drug-free" vs. "cheating-free" sport. Finally, we consider the role and key components of anti-doping education and how the relevance of certain components may be dependent on the way clean sport is defined. Conceptualizing doping as a sport integrity issue, we move away from the archaic and delimiting view of clean sport as drug-free sport and conclude with recommendations on how to reconcile values-based education, awareness raising, information provision and anti-doping education within the broader scope of integrity, to support informed decision making and personal agency. To connect anti-doping education to individual-level decision making, we recommend a staggered approach in which specific education content is linked to different influences in the decision-making process, to different stages of athlete development, and to different educational goals. Emphasizing and encouraging sensemaking in anti-doping decision making offers a pragmatic approach for anti-doping education. Conceptual clarity and precise mapping of the educational goal, content, and delivery is vital for valid and meaningful evaluation of the effectiveness of anti-doping education.

Generating evidence on the use of Image and performance enhancing drugs in the UK: results from a scoping review and expert consultation by the Anabolic Steroid UK network.

BACKGROUND: The use of anabolic androgenic steroids (AAS) and associated image and performance enhancing drugs (IPEDs) is now a global phenomenon. There is a need to develop evidence to support the development of interventions to prevent the commencement of use, to minimise the potential harms or to support those in their cessation of use. While the United Kingdom (UK) is no exception to this issue, its public health and legislative response to the phenomenon differs to other countries and requires the examination of research specific to the UK. Therefore, a scoping review has been conducted to examine the recent relevant literature to help inform the development and evaluation of effective interventions to reduce the harmful use of IPEDs. METHODS: A comprehensive search strategy was developed for multiple bibliographic databases, supported by and iterative citation searching process and complimented by expert input from the Anabolic Steroid UK Network. Research conducted by or UK academics or within the UK were eligible, if published in the previous five years. RESULTS: In total 87 eligible outputs were identified, including 26 review articles, 25 qualitative papers and 24 quantitative papers. together with small numbers of clinical studies/case reports (6) and commentaries/correspondence (6). The most common topics of research were public health, treatment and harm reduction (41), followed by studies focusing on epidemiology, sub-groups of people using IPEDs and motivations for use (34). The studies illustrated the diverse populations of people who use a range of enhancement drugs including concomitant psychoactive drug use. A number of papers focused on blood borne viruses and associated issues, while others reported on the uptake of needle and syringe programmes. No effectiveness evaluations related to any aspect of treatment, harm reduction or other intervention were published during study period. CONCLUSION: There is a need for the development of effectiveness evaluations of current interventions and any future service provision for people using image and performance enhancing drugs. While there have been no studies of this nature to date, this review illustrates the rich data that has been gathered through diverse methodologies, that will assist in the development of future effectiveness evaluations.

"Beyond the Rink": A Multilevel Analysis of Social Identity Behaviors Captured Using the Electronically Activated Recorder.

This study used ecological sampling methods to examine associations between youth athletes' experiences receiving and engaging in behaviors indicative of in-group ties, cognitive centrality, and in-group affect (i.e., social identity) during a 3-day competitive ice hockey tournament. Forty-five youth (Mage = 12.39 years; SDage = 1.14 years; 94% male) from nine teams wore an electronically activated recorder that captured brief (50-s) audio observations throughout the tournament. Participants also completed daily diary questionnaires for each day of competition. Multilevel structural equation modeling demonstrated that athletes were more likely to engage in behaviors indicative of in-group affect and cognitive centrality on days when they received as higher-than-average frequency of behaviors indicative of cognitive centrality from teammates, coaches, and parents. The findings suggest that when team members interact in ways that demonstrate they are thinking about their team, they influence fellow members to behave in ways that promote a sense of "us."

Social media use informing behaviours related to physical activity, diet and quality of life during COVID-19: a mixed methods study.

BACKGROUND: This mixed methods study explored how social media use informed physical activity and diet-related behaviours, and self-perceived Quality of Life (QoL) during COVID-19, and assessed the contextual factors that drive social media use for health-related behaviour change in diverse groups. During the COVID-19 lockdown periods there were reported changes to social media use and health behaviours, and this gave an opportunity to investigate potential relationships. METHODS: An explanatory sequential research design of two parts was used: (1) An online survey that assessed social media use in relation to physical activity levels, diet quality and QoL (n = 786; Mage 45.1 ± 19.1 (range 16-88) years; Female =69%); (2) 20 purposive focus groups (n = 69; Mage = 52.88 ± 18.45 years, Female n = 68%) to understand the contextual factors that drive social media use for health-related behaviour change. Descriptive and thematic analysis were conducted. RESULTS: Participants in this study reported that social media facilitated the self-management of behaviours related to physical activity, diet and QoL, through access to information to inform workouts and dietary quality, and the opportunities for interaction with peers, family members and within social groups. Contextual factors including work, home and lifestyle arrangements, pre-existing health-related knowledge and behaviours, and the perceived value of social media for health influenced the relationship between social media use and self-reported outcomes. Social media influencers, peers/family members, and official organisations influenced the application of health-related information accessed via social media. CONCLUSIONS: The evidence shows that participants were critical users of social media and were able to use social media to derive benefit for their health and wellbeing. Detailed guidance for those who use social media, as well as those who recommend and endorse social media content is required to maximise the potential of social media to support health behaviours. Future public health strategies and social media interventions should acknowledge diversity in contextual factors driving social media use for health behaviour change.

A Scoping Review of Non-Medical and Extra-Medical Use of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs).

Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most commonly used medications worldwide and have analgesic, antipyretic and anti-inflammatory properties. Although NSAIDs are recognised as generally safe and effective, non-medical and extra-medical use of these products can occur. Unlike the use of illegal and many prescription drugs, which are subject to extensive research attention, inappropriate use of NSAIDs has been less well investigated. This scoping review collates and describes what is known regarding non-medical and extra-medical use of NSAIDs. In total, 72 studies were included in this scoping review. Three themes emerged from the review: (1) indicative profile of people who engage in non-medical or extra-medical use of NSAIDs; (2) antecedents for non-medical or extra-medical use; and (3) adverse health effects of non-medical and extra-medical use of NSAIDs. The review concluded that there is a need for enhanced patient education, including among sports people; pharmacovigilance in terms of clinician recognition of aberrance; and prescriber and pharmacist awareness of the potential for extra-medical and non-medical use and the related health harms.

The Impact of the COVID-19 Pandemic on Male Strength Athletes Who Use Non-prescribed Anabolic-Androgenic Steroids.

Background: One sub-population potentially affected by the COVID-19 pandemic are strength athletes who use anabolic-androgenic steroids (AAS). We examined links between disruption in AAS use and training due to the pandemic and mental health outcomes in this population, hypothesising: (a) the pandemic would be linked with reduced training and AAS use; and (b) athletes perceiving greater impact on their training and AAS use would report increases in detrimental mental health outcomes. Methods: Male strength athletes using AAS (N = 237) from 42 countries completed an online questionnaire in May 2020. A sub-sample (N = 90) from 20 countries participated again 4 months later. The questionnaire assessed pre-pandemic and current AAS use and training, alongside several mental health outcomes. Results: At Time 1, most participants perceived an impact of the pandemic on AAS use (91.1%) and/or training (57.8%). Dependent t-tests demonstrated significant reductions in training frequency (t = 7.78; p < 0.001) and AAS dose (t = 6.44; p < 0.001) compared to pre-pandemic. Linear regression showed the impact of the pandemic on training was a significant positive predictor of excessive body checking (B = 0.35) and mood swings (B = 0.26), and AAS dose was a significant positive predictor of anxiety (B = 0.67), insomnia (B = 0.52), mood swings (B = 0.37). At Time 2, fewer participants perceived an impact of the pandemic on AAS use (29.9%) and/or training (66.7%) than at Time 1. Training frequency (t = 3.02; p < 0.01) and AAS dose (t = 2.11; p < 0.05) were depressed in comparison to pre-pandemic. However, AAS dose had increased compared to Time 1 (t = 2.11; p < 0.05). Linear regression showed the impact of the pandemic on training/AAS use did not significantly predict any mental-health outcomes. However, AAS dose was a significant negative predictor of depressive thoughts (B = -0.83) and mood swings (B = -2.65). Conclusion: Our findings showed impact of the pandemic on the training and AAS use, reflected in reduced training frequency and AAS dose. However, whilst we detected some short-term consequential effects on mental health, these did not appear to be long-lasting.

Co-creating a social science research agenda for clean sport: An international Delphi study.

BACKGROUND: Doping in sport is a significant issue. To date, research informing doping prevention has lacked a framework guiding research priorities. To ensure research is coordinated, sustainable and focused on end-user priorities, this study co-created the first research agenda for doping prevention. METHODS: The Delphi method was used to develop this agenda. Based upon two substantive reviews of the doping literature and 12 focus groups across five countries, a questionnaire was developed assessing the importance of 15 research topics and identifying research questions.  Eighty-two anti-doping stakeholders with relevant expertise were invited to be panel members. In Round 1, an expert panel (n = 57; 70% response rate) completed this questionnaire. In Round 2, panel members (n = 33; 58% response rate) ranked for relative importance the eight topic areas rated highest in Round 1, before doing the same for research questions within each topic. Based on these rankings, a draft agenda was created. In Round 3, panel members (n = 26; 79% response rate) rated the degree to which they accepted this agenda, the feasibility of its delivery and identified possible barriers and facilitators to implementation. RESULTS: The results of Round 1 and Round 2 were used to create a draft agenda consisting of 18 research questions stratified across eight topic areas. This agenda was either fully (n = 16) or mostly (n = 9) accepted by the panel in Round 3 (96.2%). Research topics included the effectiveness of interventions/education programmes, environmental influences, long-term development of protective and risk factors in athletes and their entourage, athletes' experiences of anti-doping procedures and athletes' place in the anti-doping system. CONCLUSIONS: A rigorous exercise created an agenda for doping prevention research. Adoption and application of this agenda should lead to better coordination, more efficient use of funding, enhanced uptake of research findings and more effective doping prevention education.

'Clean athlete status' cannot be certified: Calling for caution, evidence and transparency in 'alternative' anti-doping systems.

Athletes, sponsors and sport organisations all have a vested interest in upholding the values of clean sport. Despite the considerable and concerted efforts of the global anti-doping system over two decades, the present system is imperfect. Capitalising upon consequent frustrations of athletes, event organisers and sponsors, alternative anti-doping systems have emerged outside the global regulatory framework. The operating principles of these systems raise several concerns, notably including accountability, legitimacy and fairness to athletes. In this paper, we scrutinise the Clean Protocol™, which is the most comprehensive alternative system, for its shortcomings through detailed analysis of its alleged logical and scientific merits. Specifically, we draw the attention of the anti-doping community - including researchers and practitioners - to the potential pitfalls of using assessment tools beyond the scope for which they have been validated, and implementing new approaches without validation. Further, we argue that whilst protecting clean sport is critically important to all stakeholders, protocols that put athletes in disadvantageous positions and/or pose risks to their professional and personal lives lack legitimacy. We criticise the use of anti-doping data and scientific research out of context, and highlight unintended harms that are likely to arise from the widespread implementation of such protocols in parallel with - or in place of - the existing global anti-doping framework.

A Longitudinal Examination of the Relations Between Moral Disengagement and Antisocial Behavior in Sport.

Moral disengagement (MD) has been positively associated with antisocial behavior (AB) in sport. However, the longitudinal associations between MD and AB are unexamined to date. Adopting a three-wave cross-lagged panel design, the authors examined the reciprocal relations between MD and two forms of AB (i.e., toward opponents and teammates) across a competitive season with a sample of 407 team-sport athletes (Mage = 15.7 years) from Canada. Using structural equation modeling, the authors found strong positive autoregressive effects for MD and both forms of AB across both time periods. They also identified strong positive synchronous correlations between MD and both types of AB at each time point. Finally, cross-lagged effects were only found between MD and AB toward opponents; effects from MD to AB toward opponents were stronger than the reciprocal effects. These findings contribute important knowledge on the regulation of AB in sport.

Perceptions of coach doping confrontation efficacy and athlete susceptibility to intentional and inadvertent doping.

OBJECTIVES: We tested a conceptually grounded model linking athlete perceptions of strength and conditioning and technical coach doping confrontation efficacy (DCE) with athletes' doping self-regulatory efficacy (SRE), doping moral disengagement (MD), and susceptibility to intentional and inadvertent doping. DESIGN: Cross-sectional, correlational. METHODS: Participants were high-level athletes (nmale  = 532; nfemale  = 290) recruited in Australia (n = 261), the UK (n = 300), and the USA (n = 261). All participants completed questionnaires assessing the variables alongside a variant of the randomized response technique to estimate the prevalence of doping. RESULTS: The estimated prevalence of intentional doping in the sample was 13.9%. Structural equation modeling established: (a) perceptions of technical and strength and conditioning coaches' DCE positively predicted doping SRE; (b) doping SRE negatively predicted doping MD; (c) doping MD positively predicted susceptibility to intentional and inadvertent doping; and (d) the predictive effects of coach perceptions on susceptibility to doping were mediated by doping SRE and doping MD. Multisample analyses demonstrated these predictive effects were invariant between males and females and across the three countries represented. CONCLUSIONS: The findings show the conceptually grounded model to offer extended understanding of how multiple individuals within the athlete support personnel network may influence athlete doping.

Sport supplement use predicts doping attitudes and likelihood via sport supplement beliefs.

The aim of this study was to examine: 1) whether sport supplement use is related to doping and 2) whether sport supplement beliefs mediated this relationship. In Study 1, athletes (N = 598), completed measures of sport supplement use, sport supplement beliefs, and doping attitudes. In Study 2, athletes (N = 475) completed measures of sport supplement use, sport supplement beliefs, and doping likelihood. In both studies, sport supplement use predicted doping outcomes indirectly via sport supplement beliefs. Our findings provide novel evidence to suggest that sport supplement users, who strongly believe that sport supplements are effective, are more likely to dope. For anti-doping organisations wishing to prevent doping, targeting an athlete's beliefs about sport supplements may improve the effectiveness of anti-doping prevention programmes.

Disentangling the Relations between Social Identity and Prosocial and Antisocial Behavior in Competitive Youth Sport.

The social identities formed through membership on extracurricular activity groups may contribute to the frequency with which youth engage in prosocial and antisocial behavior. However, researchers have yet to disentangle the individual- and group-level processes social identification effects operate through; sex and perceived norms may also moderate such effects. Thus, we investigated the hierarchical and conditional relations between three dimensions of social identity (i.e., ingroup ties, cognitive centrality, ingroup affect) and prosocial and antisocial behavior in youth ice hockey players (N = 376; 33% female). Multilevel analyses demonstrated antisocial teammate and opponent behavior were predicted by cognitive centrality at the team level. Further, prosocial teammate behavior was predicted by cognitive centrality and ingroup ties at the individual-level. Also, perceived norms for prosocial teammate behavior moderated the relations between ingroup ties, cognitive centrality, and ingroup affect and prosocial teammate behaviour. Finally, sex moderated the relations between cognitive centrality/ingroup affect and antisocial opponent behavior. This work demonstrates the multilevel and conditional nature of how social identity dimensions relate to youth prosocial and antisocial behavior.

Empathic and Self-Regulatory Processes Governing Doping Behavior.

Evidence associating doping behavior with moral disengagement (MD) has accumulated over recent years. However, to date, research examining links between MD and doping has not considered key theoretically grounded influences and outcomes of MD. As such, there is a need for quantitative research in relevant populations that purposefully examines the explanatory pathways through which MD is thought to operate. Toward this end, the current study examined a conceptually grounded model of doping behavior that incorporated empathy, doping self-regulatory efficacy (SRE), doping MD, anticipated guilt and self-reported doping/doping susceptibility. Participants were specifically recruited to represent four key physical-activity contexts and consisted of team- (n = 195) and individual- (n = 169) sport athletes and hardcore- (n = 125) and corporate- (n = 121) gym exercisers representing both genders (nmale = 371; nfemale = 239); self-reported lifetime prevalence of doping across the sample was 13.6%. Each participant completed questionnaires assessing the aforementioned variables. Structural equation modeling indicated strong support for all study hypotheses. Specifically, we established: (a) empathy and doping SRE negatively predicted reported doping; (b) the predictive effects of empathy and doping SRE on reported doping were mediated by doping MD and anticipated guilt; (c) doping MD positively predicted reported doping; (d) the predictive effects of doping MD on reported doping were partially mediated by anticipated guilt. Substituting self-reported doping for doping susceptibility, multisample analyses then demonstrated these predictive effects were largely invariant between males and females and across the four physical-activity contexts represented. These findings extend current knowledge on a number of levels, and in doing so aid our understanding of key psychosocial processes that may govern doping behavior across key physical-activity contexts.
