Objective: Orthorexiaisa pathological fixation about the consumption of healthy food. The present study aimed to reveal the psychometric properties of the Turkish version of ORTO-15, which was developed to evaluate orthorexia, and to investigate the relationship betweenorthorexia, and eatingattitude, obsessive-compulsive symptoms, and some demographic variables.

Method: The study included 994 participantsaged between 19 and 66 years. ORTO-15, the Maudsley Obsessive-Compulsive Inventory, and theEating Attitude Test-40 were administeredto the participants.

Results: A 3-factor solution with varimax rotation explained 40.62% of the variance. When 4 items with factor loadings below± 0.50 were eliminated from ORTO-15, the Cronbach'salpha coefficient was 0.62. The remaining 11 items were thought to have statistically satisfactory properties for the Turkish version of ORTO and were collectively referred to as ORTO-11. This version was used to investigate the relationship between orthorexia, and eating attitude and obsessive-compulsive symptoms. Pathological eating attitude and obsessive-compulsive symptoms were related toorthorexia. Women exhibitedmore orthorexic symptomsthen men. In the present study high a body mass index was an important variable for orthorexia, but only together with gender (female), pathological eating attitude, and increased obsessive-compulsive symptoms. The results, implications, and limitations of the study arediscussed.

Conclusion: ORTO-11 demonstrated statistically satisfactory properties. Orthorexia was related to pathological eating attitude and obsessive-compulsive symptoms; however, caution should be used whengeneralizing the reported results.
