[Truncated abstract] This study empirically examines the Sport Drug Control model (Donovan et al. 2002) via survey data of a large sample of elite Australian athletes. The model consists of six components believed to predict an athlete’s attitude (and intentions) towards performance-enhancing substances use: (1) threat appraisal; (2) benefit appraisal; (3) personal morality; (4) legitimacy; (5) personality; and (6) reference group opinion. In addition, two 'market' factors, the affordability and availability of drugs, believed to facilitate or inhibit the translation of attitudes and intentions into behaviour are included in the model. To date the sports literature shows no systematic national or international single source research covering the views of athletes on the comprehensive list of factors in the Sport Drug Control model. A cross-sectional nationwide mail survey of 1,237 elite Australian athletes was conducted. Prior to the mail-out, the survey instrument measuring all of the constructs in the Sport Drug Control model was pre-tested among athletes in focus group discussions and a small scale survey. A structural equation modelling approach was employed to test the Sport Drug Control model. The findings provided empirical validation of the theoretical model; the test model accounted for 81% of the variance in attitude towards performance-enhancing substances use and 13% of the variance in doping behaviour.
