OBJECTIVES: The aims of this article are to describe the development of a self-administered questionnaire assessing the core values in the field of public health (radardesvaleurs.com) and to report the results of a study testing the questionnaire's test-retest reliability, internal consistency and construct validity. METHOD: A 24-item questionnaire grounded in the conceptual framework of Shalom H. Schwartz (2000) was developed by a group of international experts in public health. Six scores were generated, each linked to a specific value and put on three axes: individualism-equity, autonomy-conformity and risk-security. The questionnaire was submitted to students attending the School of Public Health of the Université de Montréal (ESPUM) (n = 700). A total of 401 students completed the questionnaire, 52 of whom completed it again one month later. RESULTS: For the test-retest reliability, all percentages of agreement were equal or superior to 60% except for a single question (50%). All Cohen's kappa coefficients of individual items were strong (> 0.60) except for three questions which presented a very high percentage of agreement. The Intraclass Correlation coefficients of the values' scores varied between 0.27 and 0.77. The three axes' internal consistency was estimated by Cronbach's alphas (between 0.46 and 0.74). The exploratory factorial analysis only partially confirmed the questionnaire's theoretical structure. CONCLUSION: Despite the limits of the results, the questionnaire has an interesting level of reliability and validity, which makes its pedagogical use pertinent to pursue. The limitation to four items/value, as well as the representativeness of the sampling (ESPUM students), could explain certain empirical shortcomings of the questionnaire.
