Abstract

ABSTRACT TRANSLATION AND VALIDATION OF THE SPANISH VERSION QUESTIONNAIRE ORTHO-15 FOR THE EVALUATION OF ORTHOREXIA. Introduction Orthorexia Nervosa (ON) is an obsession for healthy eating. There is a diagnostic questionnaire, named ORTHO-15, developed in Italian language to measure the orthorexia tendency. There are also similar questionnaires known as the ORTHO-11 and the ORTHO-9, which are adaptations from the ORTHO-15. It is important to mention that there is no known translation of the questionnaire ORTHO-15 to Spanish language with its corresponding validation. Aims Translate the ORTHO-15 into Spanish and validate it into our target population among women in undergraduate college. Methods A validation study of the questionnaire ORTHO-15 was conducted in three phases: Phase (1) was the translation, in step (2) cultural adaptation and expert judgment, finally in the phase (3) we applied the validation, developed with the final questionnaire. Findings The ORTHO-15 presented the following fit indices CFI = 0,783; TLI = 0,738; RMSEA 0,072; χ2 = 466, 38 and Cronbach's alpha = 0, 73. The model 2 of ORTHO 11 from the adapted version of Hungary presented CFI = 0,853; TLI = 0,816; RMSEA 0.074; χ2 = 102, 9 and Cronbach's alpha = 0, 74. Finally, the model 3 of ORTHO 9 from Alemania presented CFI = 0,752; TLI = 0,669; RMSEA 0.096; χ2 = 91, 27 and Cronbach's alpha = 0, 64. Of the three models reported, the model 2 was the one that best fitted our data and best adapted to our reality. Conclusion The best questionnaire to assess the tendency to ON in the target population is the ORTHO-11 which presented better psychometric properties compared with ORTHO-9 and ORTHO-15.
