Method this work was based on the testing procedure of the paper- and-pen personalized single-category iat test (i.e., p&p sc- iat-p) of bardin et al. (2016), which we enriched with the procedure of boateng et al. (2018). this paper was built around four studies: (a) the first study consisted in the development of a preliminary version of the iat-dop, (b) the second study measured the dimensionality and criterion validity of the iat-dop to confirm the structure of the p&p version, (c) the third study verified its test-retest reliability, and (d) the fourth study explored the relations between the p&p and computerized versions of the iat-dop as a first approach to construct validity. results study 1 developed a preliminary french version of the iat- dop based on chan et al.’s iat proposal (2017). study 2 provided preliminary support to the dimensionality and criterion validity of the tool. study 3 demonstrated the test- retest reliability of the instrument. finally, study 4 suggested the construct validity of the iat-dop through a significant correlation between the computerized and p&p versions. conclusion the iat-dop is a preliminary tested french-language version of a tool for measuring athletes’ implicit attitudes toward doping, with the advantages of simplicity, low cost, and quick administration. this tool should contribute to the better
