Structural validation of the ORTO-12-FR questionnaire among a French sample as a first attempt to assess orthorexia nervosa in France
Purpose: To the best of our knowledge, no scientific publications on orthorexia nervosa have been based on a French population. The goal of our study was to confirm the factor structure of the French version of the ORTO-15 questionnaire. Methods: An online survey (N = 768) was conducted asking participants (84.77% were women) to answer several questions about their dietary habits and to assess orthorexia nervosa using the ORTO-15 scale. Confirmatory factor analysis (CFA) was used for the validation.
