WADA Social Science Research

According to its website, WADA is committed to improving evidence-based doping prevention strategies through social science research. Understanding the fundamental differences between athletes who choose to compete clean and those who resort to doping or why some athletes decided to dope – despite being well aware of the harmful effects of doping and of anti-doping rules - will assist in ensuring that doping prevention strategies are effective and efficient. In fact, I contributed to this research myself after testing positive and owning-up to my involvement in doping, and was honored to have the opportunity to do so.



WADA’s Social Science Research Grant Program was created to ensure that preventive anti-doping education programs were designed using an evidence-based approach. Since the creation of the Program in 2005, 26 projects have been funded with awards nearing the US$730,000 mark.



Target Research Program
To further ensure effective doping prevention strategies, WADA’s Education Committee identifies specific areas that they feel require additional evidence in the way of social science research. Several years worth of WADA-funded research is available for review online here. One study of particular interest to this author, The Development and Validation of a Doping Attitudes and Behaviour Scale (DABS), is summarized below, and a subsequent post will present the full results of the study.

The Development and Validation of a Doping Attitudes and Behaviour Scale (DABS) - PROJECT SUMMARY

"Athletes’ use of prohibited ergogenic substances for performance enhancement is a form of cheating behaviour which can jeopardise their health and careers. Unfortunately, few studies have attempted to understand the psychological mechanisms underlying such behaviour (Roberts et al., 2004). This oversight is unfortunate because anti-doping measures cannot be fully effective unless they address the reasons why athletes engage in cheating in the first place. Against this background, Moran, Guerin, McCaffrey & MacIntyre (2004) conducted a qualitative study of Irish athletes’ understanding of cheating in sport. They discovered that cheating was perceived to occur along a continuum of behaviour ranging from less serious activities such as “smart play” (or gamesmanship), at one end, to the use of banned substances to enhance performance (doping), at the other end. They also found that cheating was rarely perceived as stemming from an individual decision by an athlete but was attributed to a particular type of coaching environment characterised by a “win at all costs” approach. Given such findings, the next step in this programme of research is to explore the “doping” end of the cheating continuum by developing a theoretically-based, self-report instrument which can measure not only athletes’ attitudes to doping but also their propensity to engage in doping behaviour. This scale development task requires three separate studies using a combination of quantitative and qualitative methodology (see Biddle, Markland, Gilbourne, Chatzisarantis & Sparkes, 2001) and is guided by the following research questions. First, what are Irish athletes and coaches’ perceptions of, and attitudes towards, doping in sport? This question will be investigated using a series of semi-structured interviews with athletes and coaches/managers from sports (e.g., athletics, cycling and weightlifting) in which doping is known to be prevalent.

Of particular interest in this study will be the attitudes and experiences of athletes who have been investigated for alleged breaches of ant-doping regulations. Second, based on the attitudes elicited by our interviews, what is the best way to design a theoretically-grounded, objectively scored, self-report scale to measure athletes’ attitudes to doping and their propensity to engage in doping behaviour? This question will be answered by rigorous psychometric analysis. Finally, what combination of relevant psychological variables produces the best prediction of a proclivity to engage in doping? Among the predictor variables to be investigated here will be moral reasoning (Tod & Hodge, 2001), perceived motivational/coaching climate (Ommundsen, Roberts, Lemyre & Treasure, 2003), attributional style (e.g., Hanrahan, Grove & Hattie, 1989) and perceived importance of competition (as there is evidence that athletes are more likely to engage in doping when the outcome is perceived as especially important). Although each of these variables has been associated with cheating in sport, no study has yet combined them statistically using multiple regression analysis to predict a propensity to engage in doping behaviour. In summary, the purpose of our study is to develop a theoretically-based, psychometrically sound, self-report scale provisionally entitled the “Doping Attitudes and Behaviour” Questionnaire to assess athletes’ attitudes to, and propensity to engage in, doping behaviour in sport."

Bike Pure - And Why the Athletes Must Speak

I had a great anti-doping heart-to-heart with BikePure earlier this afternoon. I wish I had $1,000,000 so I could donate part of it to support BP and propagate their message...I don't, but I'm still trying to help by contributing to BP the details of my sordid affair with EPO and doping in general. I hope other cyclists who've taken similarly misguided paths will consider working with BikePure to drive the grassroots fight against doping - which has to start with free, open dialogue and a realistic assessment of what the hell has been going on not just in cycling, but in sport in general with regards to the use of performance enhancing drugs and illegal methods of preparation.

I believe that it is vitally important for athletes who've doped and are seeking redemption to tell the truth about what they did, what they gained by doping, and perhaps most importantly, what they may have lost. Doping is something that pays almost immediate dividends, but apart from perhaps the monies spent on actual doping products or medical supervision, it doesn't reveal its full cost in terms of harming the well-being of the athlete and his sport until much later - and usually only after the wheels have come off. Scientific studies and research, including as the work done by Birekeland KI, Stray-Gundersen J, Hemmersbach P, et al. Effect of rhEPO administration on serum levels of sTfr and cycling performance. Med Sci Sport Exerc 2000; 32:1238-43, have confirmed that EPO can improve athletic performance in as little as four weeks, but there is little data or even informed discussion of the long-term adverse effects of EPO use on the physical and mental health of athletes. Patrick Mignon of France's CESAMES - the Research Center on Mental Health, Psychotropics, and Society - writes:

"If the knowledge of the physiological effects of doping has progressed, this is not the case for that about the long term consequences of doping on the state of health of former athletes, whose physical dependency might be one of the characteristics. This calls for the appropriated apparatuses for observation that could link the careers of athletes to their health history (wounds, consumption of psychoactive substances, recourse to mental health) and quantitative studies (combination of grids for questionnaires, elaboration of questionnaires aimed at targeted groups or at the general population). The analysis of the pharmacological effects of a substance is not enough. To it must be added the sociological analysis of dependency as a dependency on a life style that supposes the involvement in the career of top level athlete. This must be carried out through the analysis of the organization of time and of the relations between an athlete and the actors in charge of them. The analysis of high level sports as a life style thus leads back to a reflection risk behavior, to analyze the question of drugs i sports as both an aspect of this life style and a way of managing the exit from the world of sports..." [Editor's note: The Research Center on Mental Health, Psychotropics and Society (CESAMES) is a mixed research unit of France's Centre National de la Recherche Scientifique (CNRS) and the University René Descartes Paris 5.]

Though I've had some opportunity to speak on the dangers of doping and retell my own story as a warning to others, I hope that over time I will be able to play a more active role in the anti-doping movement, especially with regards to educating young athletes on the full spectrum of risks they face by involving themselves in doping.

More on the Birkeland study:

"BIRKELAND, K. I., J. STRAY-GUNDERSEN, P. HEMMERSBACH, J. HALLEN, E. HAUG, and R. BAHR. Effect of rhEPO administration on serum levels of sTfR and cycling performance. Med. Sci. Sports Exerc., Vol. 32, No. 7, pp. 1238-1243, 2000.

Purpose: We assessed the possibility of using soluble transferrin receptor (sTfR) as an indicator of doping with recombinant erythropoietin (rhEPO).

Methods: A double-blind, placebo-controlled study was conducted with the administration of 5000 U of rhEPO (N = 10) or placebo (N = 10) three times weekly (181-232 U[middle dot]kg-1[middle dot]wk-1) for 4 wk to male athletes. We measured hematocrit and the concentration of hemoglobin, sTfR, ferritin, EPO, and quantified the effects on performance by measuring time to exhaustion and maximal oxygen uptake ( O2max) on a cycle ergometer.

Results: Hematocrit increased from 42.7 /- 1.6% to 50.8 /- 2.0% in the EPO group, and peaked 1 d after treatment was stopped. In the EPO group, there was an increase in sTfR (from 3.1 /- 0.9 to 6.3 /- 2.3 mg[middle dot]L-1, P < 0.001) and in the ratio between sTfR and ferritin (sTfR[middle dot]ferritin-1) (from 3.2 /- 1.6 to 11.8 /- 5.1, P < 0.001). The sTfR increase was significant after 1 wk of treatment and remained so for 1 wk posttreatment. Individual values for sTfR throughout the study period showed that 8 of 10 subjects receiving rhEPO, but none receiving placebo, had sTfR levels that exceeded the 95% confidence interval for all subjects at baseline (= 4.6 mg[middle dot]L-1). O2max increased from 63.6 /- 4.5 mL[middle dot]kg-1[middle dot]min-1 before to 68.1 /- 5.4 mL[middle dot]kg-1[middle dot]min-1 2 d post rhEPO administration (7% increase, P = 0.001) in the EPO group. Hematocrit, sTfR, sTfR[middle dot]ferritin-1, and O2max did not change in the placebo group."

Wear Cologne - Seduce Women

Interesting article from The Economist dealing with perfume/cologne/artificial scent:

"...Craig Roberts of the University of Liverpool and his colleagues—working with a team from Unilever’s research laboratory at nearby Port Sunlight—have been investigating the problem. They already knew that appropriate scents can improve the mood of those who wear them. What they discovered, though, as they will describe in a forthcoming edition of the International Journal of Cosmetic Science, is that when a man changes his natural body odour it can alter his self-confidence to such an extent that it also changes how attractive women find him..."

The Doping Dilemma

The Doping Dilemma - Game theory helps to explain the pervasive abuse of drugs in cycling, baseball and other sports
By Michael Shermer

"For a competitive cyclist, there is nothing more physically crushing and psychologically demoralizing than getting dropped by your competitors on a climb. With searing lungs and burning legs, your body hunches over the handlebars as you struggle to stay with the leader. You know all too well that once you come off the back of the pack the drive to push harder is gone—and with it any hope for victory.

I know the feeling because it happened to me in 1985 on the long climb out of Albuquerque during the 3,000-mile, nonstop transcontinental Race Across America. On the outskirts of town I had caught up with the second-place rider (and eventual winner), Jonathan Boyer, a svelte road racer who was the first American to compete in the Tour de France. About halfway up the leg-breaking climb, that familiar wave of crushing fatigue swept through my legs as I gulped for oxygen in my struggle to hang on..."
