The relationship between attitudes towards doping and behavioural intentions to dope: The role of attitude certainty

Participants were spanish athletes who reported their attitudes and behavioural intentions regarding doping itself, as well as attitudes and behavioural intentions regarding a legalisation proposal. As expected, attitudes predicted intentions in both cases.

Most importantly, we hypothesised and found an interaction between attitudes and attitude certainty on intentions. That is, attitudes towards doping predicted intentions to dope to a greater extent for participants with higher (vs. lower) certainty in their attitudes. Likewise, attitudes towards the legalisation proposal predicted intentions to support that proposal and to engage in the banned behaviours if legalised to a greater extent for participants with higher (vs. lower) certainty in those attitudes
