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
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.
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.
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.
