Development, validation and application of a Brazilian knowledge scale about sports doping in dentistry

Abstract

To evaluate the knowledge of Brazilian dentists of sports doping through the development, validation and application of the Brazilian Knowledge Scale about Sports Doping in Dentistry (B-KSSDD). A scale with 12 items was developed to assess a dentist’s ability to determine whether the use of a medication characterised sports doping according to the World Anti-Doping Agency. A preliminary study to validate the B-KSSDD was carried out with 135 dentists, allowing the evaluation of ceiling and floor effects, convergent and discriminant validity, test-retest reliability and internal consistency of the instrument. A sample size calculation using the results of the preliminary study and the B-KSSDD was completed online using SurveyMonkey® by 270 participants from all regions of the country. The B-KSSDD showed evidence of convergent and discriminant validity, good temporal stability (ICC = 0.75) and internal consistency (alpha = 0.89). In the main study, the participants obtained an average score of 4.19/12 points on the B-KSSDD, suggesting that these professionals have insufficient knowledge about sports doping. The age of participants showed a negative association with knowledge about doping, while frequency of treating athletes and frequency of performing surgeries showed positive associations with knowledge about doping. The dentists had insufficient knowledge of the subject. Age of participants and frequency with which they attend to athletes are associated with knowledge about sports doping. Professional updating and education policies on doping are necessary for dentists, as athlete patients are at risk for severe sporting and financial penalties.

Introduction

The term doping was formally defined in 1889, when an English dictionary described it as a mixture of opium and narcotics in horses.11. Goldman B, Klatz R. Death in the locker room: drugs and sports paperback. Dacula: Elite Sports Medicine; 1992. However, the use of doping substances in horses and athletes arose in the Roman period, when they were used to increase the capacity and strength of these animals and gladiator athletes as the prestige of sports grew.22. Voy RO, Deeter KD. Drugs, sport, and politics. Champaign: Leisure; 1991. With the evolution of sports and the advent of sports medicine, the International Federation of Sports Medicine defined sports doping as the act of an athlete intentionally or unintentionally using substances or methods prohibited by the International Olympic Committee (IOC).33. The International Federation of Sports Medicine. FIMS position statement: statement on doping in sport. Lausanne: The International Federation of Sports Medicine; [cited 2020 Jun 16].

In 2002, the World Anti-Doping Agency (WADA) published the World Anti-Doping Code (Code)44. World Anti-doping Agency. World anti-doping code; 2012 with 2019 amendments. 2 ed. Montreal: World Anti-doping Agency; 2019 [cited 2020 Jun 26].

https://www.wada-ama.org/sites/default/f...
, which determined doping control guidelines and was adopted by more than 660 sports entities, including the IOC, the International Paralympic Committee, international federations and national anti-doping organisations.

In addition to the Code, which was last published in 2015, the WADA annually publishes an updated list of prohibited substances that can potentially be used for doping in athletes, since they can induce an artificial increase in athletes’ sports performance. The Code also addresses the sanctions applicable to athletes, teams or even sports entities, ranging from the loss of medals, points and prizes to financial consequences.44. World Anti-doping Agency. World anti-doping code; 2012 with 2019 amendments. 2 ed. Montreal: World Anti-doping Agency; 2019 [cited 2020 Jun 26].

https://www.wada-ama.org/sites/default/f...

The document updated annually by the WADA includes substances belonging to different therapeutic classes, such as anabolic agents, hormones and metabolic modulators, stimulants and glucocorticoids, that can be banned both during and outside the competition period.55. World Anti-doping Agency. The World Anti-Doping Code: international standard: phohibited list; january 2020. Montreal: World Anti-doping Agency; 2020.

https://www.wada-ama.org/sites/default/f...
Many of the drugs included in this list can be purchased in pharmacies over the counter or by prescription from health professionals such as doctors and dentists, who may inadvertently prescribe their use. Sometimes dental care may require the dentist to prescribe medications such as glucocorticoids and stimulants that, when used by athletes, can be characterised as sports doping, making the athlete susceptible to serious penalties.44.

Pluim B. A doping sinner is not always a cheat. Br J Sports Med 2008;42(7):549-50.8. For this reason, it is essential that dentists are knowledgeable about sports doping and are prepared to assist athletes without putting them at risk of positive results in doping tests.

In view of the lack of studies assessing the knowledge of dentists about sports doping and substances forbidden for athletes, the objective of this study was to report the development, validation and application of the Brazilian Knowledge Scale about Sports Doping in Dentistry (B-KSSDD).

Methodology

The study was conducted in accordance with the 1964 Helsinki Declaration and approved by the Research Ethics Committee of Clementino Fraga Filho University Hospital, at Federal University of Rio de Janeiro (protocol nº. 3.940.568). All participants signed informed consent forms in order to take part in the study.

Study design and participants

This cross-sectional study included Brazilian dentists of both genders from all regions of the country, including dentists with professional registration at their respective regional dentistry councils. Participants in the preliminary and main studies answered an electronic questionnaire, hosted by SurveyMonkey Inc. (San Mateo, USA), that tested the professionals’ knowledge about medicines that, when used by athletes, do or do not characterise sports doping.

The questionnaire consisted of questions on the participants’ sociodemographic and professional information; a question on self-assessment of their knowledge about sports doping, ranging from 1 (none) to 5 (excellent); and the B-KSSDD in Brazilian Portuguese.

Preliminary study: development and validation of the B-KSSDD

Before beginning the main study, the questionnaire was developed and validated in six steps: a) elaboration of the questions; b) specialised technical evaluation; c) general evaluation by dentists; d) evaluation of linguistics and comprehensibility; e) finalisation of the B-KSSDD; and f) assessment of the validity and reliability of the B-KSSDD (test-retest).

Elaboration of the questions

One graduate student in dentistry, one endodontist, one paediatric dentist and one orthodontist consulted the Code and Prohibited List44. World Anti-doping Agency. World anti-doping code; 2012 with 2019 amendments. 2 ed. Montreal: World Anti-doping Agency; 2019 [cited 2020 Jun 26].

and investigated the absence or presence of drugs with potential use in dental practice (such as non-steroidal anti-inflammatory, glucocorticoids and analgesics). The scale’s questions were closed and contained medications with potential or not to cause doping according to WADA documents44. World Anti-doping Agency. World anti-doping code; 2012 with 2019 amendments. 2 ed. Montreal: World Anti-doping Agency; 2019 [cited 2020 Jun 26].

and adopted the following model:

The use of [DRUG AND ADMINISTRATION] (for example, [COMMERCIAL NAME]), prescribed by a dental surgeon to an athlete who is in competition, characterises sports doping.

Answer: Agree / Disagree / Don’t know

Specialised technical evaluation

The questions were submitted to a dentist specialised in Sports Dentistry. This professional was asked whether the scale effectively assessed the dentist’s knowledge about sports doping. After the professional’s evaluation, his suggestions were incorporated or modified in the instrument.

General evaluation by dentists

Ten dentists (three oral and maxillofacial surgeons, one stomatologist, one periodontist, one orthodontist, one restorative dentist, two paediatric dentists and one general dentist) evaluated the clarity and comprehensibility of the B-KSSDD.

Linguistic and comprehensibility evaluation

The questions were submitted to a journalist and an educator, who evaluated the linguistic and grammatical aspects of the B-KSSDD.

Finalisation of the Brazilian Knowledge Scale about Sports Doping in Dentistry (B-KSSDD)

The considerations and suggestions made by the evaluators were analysed and incorporated into the scale. The final version of the scale has 12 objective questions that evaluate the dentists’ knowledge about the substances forbidden for use by athletes subject to doping control, as determined by the WADA. Each question offers three answer options: ‘agree’, ‘disagree’ or ‘don’t know’. For each correct answer, 1 point was added to the participant’s final score, while for each incorrect answer or ‘don’t know’, 0 points were added to the score. The final score of each participant could range from 0 (no correct answers/complete lack of knowledge) to 12 points (complete knowledge). As the professionals were Brazilian, the questions were provided in Portuguese (Table 1).

Validity and reliability of the questionnaire

The questionnaire test was given to 135 general dentists or specialists (from 16 different specialties), and 15 days later, 50 of these professionals were randomised using BioEstat 5.3 (Instituto Mamirauá, Belém, Brazil) to complete a retest of the questionnaire. These professionals were not included in the main study.

The validation analysis assessed the following data: floor and ceiling effects, by analysing the frequency of responses for each total score of the scale;88.

The intraclass correlation coefficient (ICC) was calculated for the total score and Cronbach’s alpha was calculated for the total scale and for the scale with items deleted, together with the item-total correlation coefficients. An ICC ≥ 0.70 and a Cronbach’s alpha between 0.70 and 0.95 were considered evidence of reliability.88. Terwee CB, Bot SD, Boer MR, Windt DA, Knol DL, Dekker J, et al.

https://doi.org/10.1016/j.jclinepi.2006....

The level of significance adopted in all analyses was 5% (α = 0.05). Data were tabulated and analysed using IBM SPSS Statistics for Windows (IBM SPSS 21.0, 2012, IBM Corp., Armonk, USA).

Main study

Sample size calculation and application

Sample size calculation considered the following parameters: effect size = 0.10, α = 0.05, power = 0.95 and number of predictors = 9. The effect size was defined through preliminary analysis using data from the 135 individuals who participated in the test phase of the scale. A minimum sample size of 245 individuals was estimated, and with 10% added to compensate for possible losses, the total number of participants was 270 dentists. The sample size was calculated using G * Power (Version 3.1.9.2, Germany).

Statistical analysis

Descriptive statistics were used to express the results as relative and absolute frequencies, means, standard deviations (SD), minimum and maximum values and 95% confidence intervals (95%CI). Simple and multiple linear regression analyses were conducted to assess the relationship between sociodemographic and professional characteristics and knowledge about sports doping. The multiple model was built using the backward method, in which all independent variables were initially incorporated into the model and the variables with the highest values of alpha (α) were subsequently removed one by one until the minimum value of 0.20 was reached. Thus, all independent variables that reached α ≤ 0.20 were maintained in the final model for purposes of adjustment. The level of significance adopted in all analyses was 5% (α = 0.05). Data were tabulated and analysed using IBM SPSS Statistics for Windows (IBM SPSS 21.0, 2012, IBM Corp., Armonk, USA).

Results

B-KSSDD validation in preliminary study

On a scale ranging from 1 (none) to 5 (excellent), dentists’ self-reported knowledge about sports doping obtained a mean score of 1.88 (SD = 0.77).

A floor effect was observed, with a response frequency of 23.7% for the minimum score; in contrast, no ceiling effect was observed, as the response frequency for the maximum score was only 1.5%.

The convergent validity analysis showed a positive and strong correlation (Rspearman = 0.57; p < 0.001) between the B-KSSDD score and the self-reported knowledge score on sports doping. The discriminant validity showed a significant difference in the B-KSSDD score between the groups of dentists who perform surgeries with lower or higher frequency (Figure 1).

Figure 1
Analysis of the discriminant validity of the Brazilian Knowledge Scale about Sports Doping in Dentistry (B-KSSDD).

Data obtained from the 135 scales completed by dentists were analysed for internal consistency. Cronbach’s alpha for the total scale was 0.89. The item-total correlation coefficients ranged from 0.47 to 0.72. The alpha values of deleted items ranged from 0.87 to 0.89. The B-KSSDD scores for the test-retest were 4.30 (SD = 3.08) and 4.80 (SD = 2.84), respectively, and the ICC was 0.75 (p < 0.001; 95%CI: 0.56–0.86).

Application of B-KSSDD in the main study

The age of the 270 dentists participating in the study ranged from 22 to 86 years (mean = 40.80; SD = 12.88) and the stratification of dentists by regions of the country was maintained in our sample (Figure 2). Table 3 shows the sociodemographic and professional characteristics. Most of the sample was female, had more than 15 years of training, had graduated from public institutions and had a specialisation. In total, 22 specialties were reported by the participants, including Sports Dentistry (n = 4; 1.5%). The four most common specialties were Orthodontics (n = 103; 38.1%), Paediatric Dentistry (n = 36; 13.3%,), Periodontics and Implantology (both with n = 21; 7.8%). Among the participants, 70% and 94.1% of professionals indicated a low frequency (never, rarely or sometimes) of performing surgeries and treating athletes, respectively.

Figure 2
Distribution of sample’s dentists in each region of the country.

Table 3
Sociodemographic characteristics of the dentists participating in the study.

The average B-KSSDD score obtained by dentists was 4.19 (SD = 3.19; 95%CI: 3.81–4.57), with 23% scoring the minimum score (0), 74.4% scoring below 7 and only 0.4% reaching the maximum score (12). In addition, we found that, only among specialists in Sports Dentistry, the average score presented was 9.25 (SD = 2.22; 95% CI: 5.72–12.0).

After applying the multiple linear regression backward method, only three variables (age, frequency of surgery and frequency of treating athletes) remained in the model for predicting knowledge about sports doping, with the other variables (gender, service region, geographic region within the State, time since graduation, institution of graduation and specialisation) were excluded because they did not reach the statistical criterion of permanence in the model (p ≤ 0.20). Table 4 shows the results of simple and multiple linear regressions for predicting knowledge about sports doping in the study participants. The univariate model showed that age was negatively associated with B-KSSDD score. In contrast, frequency of performing surgeries and frequency of treating athletes were positively associated with B-KSSDD score. All these associations were maintained in the multiple regression model; therefore, the adjusted analysis indicated that age (negative association) and frequency of performing surgeries and frequency of treating athletes (positive associations) were independent predictors of knowledge about sports doping.

Discussion

Validity and reliability of B-KSSDD – preliminary study

The validation of an instrument is a fundamental step to ensure its accuracy in assessing the objectives for which it is proposed to evaluate, and B-KSSDD showed good reliability, as assessed using the criteria of internal consistency and temporal stability (agreement between test-retest). The fact that B-KSSDD has a floor effect but does not have a ceiling effect suggests that dentists have insufficient knowledge about sports doping and the substances that characterise it, in line with the low average score obtained for the question that assessed the professionals’ self-reported knowledge about sports doping. The B-KSSDD demonstrated convergent validity, as a positive and strong correlation was observed between the score obtained in the B-KSSDD and the self-reported knowledge score on sports doping, showing that the scale is effective88. Terwee CB, Bot SD, Boer MR, Windt DA, Knol DL, Dekker J, et al. Quality criteria were proposed for measurement properties of health status questionnaires. J Clin Epidemiol. 2007 Jan;60(1):34-42. https://doi.org/10.1016/j.jclinepi.2006.03.012
https://doi.org/10.1016/j.jclinepi.2006....
in assessing the knowledge of dentists about the subject. In addition, the scale presented good discriminating properties, with a significant difference in scores between the groups of dentists who perform surgeries less or more frequently. The scientific literature evaluating the domain of pharmacology and prescriptions among the different areas of dentistry is sparse. However, these data may indicate that, as dentists who perform surgeries more frequently also prescribe drugs more frequently (due to the procedures), these professionals may have greater knowledge of the mechanisms of action of these substances and, consequently, on their potential capacity to increase the performance of athletes, which characterises sports doping.

Main study

In general, the demographic characteristics of this study were compatible with the national panorama of Brazilian dentists. The highest percentage of professionals in the main study practiced in the south and southeast regions, which is compatible with the proportion of dentists working in these regions (68.5%) according to the Federal Council of Dentistry of Brazil (FCD),1010. Conselho Federal de Odontologia. Dados estatísticos de profissionais e entidades ativas por localidade. Brasília, DF: Conselho Federal de Odontologia; 2020 [cited 2020 Jun 15]. Available from: https://www.website.cfo.org.br/dados-estatisticos-de-profissionais-e-entidades-ativas-por-localidade/
https://www.website.cfo.org.br/dados-est...
showing that this study provides a national panorama of knowledge about sports doping by dentists in the country. Although we can consider that the numerical representativeness of the sample in relation to the distribution by regions is according to the panorama of the country, the final sample is not homogeneous enough, since it is predominantly female. However, though the FCD does not make available on its website the general percentage of dentists according to sex, among experts, the entity states that, as in our study, most are female.1212. Conselho Federal de Odontologia. Quantidade geral de cirurgiões-dentistas especialistas. Brasília, DF: Conselho Federal de Odontologia; 2021 [cited 2021 Mar 8]. Available from: https://website.cfo.org.br/estatisticas/quantidade-geral-de-cirurgioes-dentistas-especialistas/
https://website.cfo.org.br/estatisticas/...
In addition, another point to be discussed is that Brazil is a continental country, with a disproportion between counties inland and capitals, which may explain the predominance of dentists working inland than in the capitals, as identified in the study by Martin et al.1313. Martin ASS, Chisini LA, Martelli S, Sartori LRM, Ramos EC, Demarco FF. Distribution of dental schools and dentists in Brazil: an overview in relation to labor market. Rev Abeno. 2018 Mar.18(1):63-73. https://doi.org/10.30979/rev.abeno.v18i1.399
https://doi.org/10.30979/rev.abeno.v18i1...

The average score obtained by dentists on the B-KSSDD in the main study shows that, in general, these professionals have insufficient knowledge about sports doping, increasing the risk that their athlete patients are inadvertently exposed to drugs that contain substances prohibited by the WADA. Although our sample contains a small number of specialists in Sports Dentistry, we observed that the average score of these professionals was approximately two times higher than that found in the total sample, suggesting that they are better able to provide dental care to athletes without placing them at risk if they are subjected to doping control. However, until March 2021, the FCD indicated that there were only 29 professional specialists in Sports Dentistry in the entire country, representing 0.02% of Brazilian dentists who have a specialisation course. Thus, the percentage of specialists in Sports Dentistry collected by our study is compatible with the small number of professionals in this field in the country.1212. Conselho Federal de Odontologia. Quantidade geral de cirurgiões-dentistas especialistas. Brasília, DF: Conselho Federal de Odontologia; 2021 [cited 2021 Mar 8]. Available from: https://website.cfo.org.br/estatisticas/quantidade-geral-de-cirurgioes-dentistas-especialistas/
https://website.cfo.org.br/estatisticas/...

The simple and multiple linear regression models for predicting knowledge about sports doping among dentists showed that age has a negative association with knowledge about sports doping, which may be related to the fact that the establishment of Sports Dentistry and the increase in training programmes in this area are recent.1414. Saini R. Sports dentistry. Natl J Maxillofac Surg. 2011 Jul;2(2):129-31. https://doi.org/10.4103/0975-5950.94465
https://doi.org/10.4103/0975-5950.94465...
In contrast, the frequencies of treating athletes or performing surgeries showed positive associations with knowledge about doping in the preliminary study. In this sense, it is highly recommended that, when seeking dental treatment, athletes and clubs hire dentists with experience in serving athletes in order to reduce the risk of punishments applied when sports doping is identified.

On the care of athletes, 5.9% of the participants said that they attend to athletes frequently (always or often). We believe that the low percentage can be justified by the fact that dentists can consider only elite athletes as “athletes”. However, the role of sports-related dentistry is also intended to benefit the health of amateurs and recreational sports practitioners, who may also eventually be subjected to doping control.1515.

In addition, international literature shows that, even among elite athletes, oral health is poor, suggesting that these professionals access dental care services infrequently.1616.

In Brazil, for example, where soccer is the main national sport, although the Brazilian Football Confederation requires that, to be considered a training club, an entity must guarantee constant dental care at a preventive or therapeutic level to athletes in training, whether through their own services, contracted or outsourced.1919.

B-KSSDD applications

This study demonstrates that the B-KSSDD is a good instrument to use in different groups of dentists, respecting cross-cultural adaptations, to assess their knowledge on substances that, when prescribed to athletes, may result in sports doping. In the face of financial and sporting punishments applied to the world sports community when doping tests return positive results, applying the B-KSSDD may help the worldwide research community and international entities identify deficiencies in dentists’ knowledge about prescribed drugs that can be characterised as sports doping, preventing these professionals from contributing to this important problem that can generate severe punishments and losses for athletes. The results found using the B-KSSDD show that the participants’ knowledge about substances prohibited by the WADA is insufficient, making athletes treated by these professionals vulnerable to the punishments indicated in the Code. Together with the results found by Mottram et al.,2222. Mottram D, Chester N, Atkinson G, Goode D. Athletes’ knowledge and views on OTC medication. Int J Sports Med. 2008 Oct;29(10):851-5. https://doi.org/10.1055/s-2008-1038403
https://doi.org/10.1055/s-2008-1038403...
who applied a questionnaire on doping that included 507 athletes, of whom only 35.1% correctly identified items on the prohibited list, the results of the present study are an alert to competent sports entities to create and/or reinforce policies to expand knowledge about sports doping among athletes, so that they can also act as disseminators of this information to health professionals who provide care to them, including dentists.

The results obtained using the B-KSSDD are also compatible with a review with a systematic search strategy, that found six articles involving health professionals (only doctors and pharmacists were found) and knowledge about doping, indicating that these professionals have limited knowledge about sports doping and the substances that characterise it.2323. Backhouse SH, McKenna J. Doping in sport: a review of medical practitioners’ knowledge, attitudes and beliefs. Int J Drug Policy. 2011 May;22(3):198-202. https://doi.org/10.1016/j.drugpo.2011.03.002
https://doi.org/10.1016/j.drugpo.2011.03...
Moreover, Woods and Moynihan,2424. Woods CB, Moynihan A. General practitioners knowledge, practice and training requirements in relation to doping in sport. Ir Med J. 2009 Jan;102(1):8-10. showed only 9% of general practitioners in medicine said they felt prepared to act to prevent doping. This suggests that, at least among the classes evaluated by the scientific community, knowledge about sports doping is a challenge for the entire health spectrum of professionals. For that reason, prevention programmes and information on sports doping should be developed and offered to athletes, doctors, coaches and family members.2525. Morente-Sánchez J, Zabala M. Doping in sport: a review of elite athletes’ attitudes, beliefs, and knowledge. Sports Med. 2013 Jun;43(6):395-411. https://doi.org/10.1007/s40279-013-0037-x
https://doi.org/10.1007/s40279-013-0037-...
Thus, the results obtained using the B-KSSDD can also promote the development of awareness and continuing education programmes on sports doping for dentists, decreasing the risk that athletes commit accidental sports doping as a result of dental care.

Study limitation

This study had limitations common in works involving questionnaires, which include the veracity of the information provided by the respondents and their commitment when answering the survey, which are also related to the comprehensibility and fluidity of the instrument. However, these limitations were reduced by the rigorous validation processes adopted during the development of B-KSSDD, described in this article. In addition, given that the scale was developed and validated in Brazilian Portuguese, this could be considered a limitation for its application in other countries, which in turn could be made possible through the cross-cultural adaptation and validation of the version suggested for the B-KSSDD in British English, available in Table 5.

Table 5
English version (not validated) suggested for the Brazilian Knowledge Scale about Sports Doping in Dentistry (B-KSSDD) and scores added to the total score according to the participants’ responses.

Conclusions

The instrument proved to be valid and reliable in assessing dentists’ knowledge about sports doping. Dentists had insufficient knowledge about sports doping, obtaining an average score of 4.19 out of 12 points on the B-KSSDD. Lower age of the professional and higher frequencies of performing surgery and treating athletes were associated with greater knowledge about sports doping. The development of professional updating policies on sports doping for dentists is important to prevent the intentional practice of doping by athletes after dental care.
