“…Despite the widespread use of the ORTO-15 in prevalence studies, there are significant variations in results even in studies with similar methodological approaches [ 13 – 15 ]. For instance, in one study with young adults, the prevalence of ON was found to be 10.9% using the ORTO-15, while in another study with a similar age group, the prevalence was found to be 60.3% using the same scale [ 16 , 17 ]. The discrepancies in results and questions about the psychometric properties of the ORTO-15 have highlighted the need for the development of a new, more accurate screening tool or scale for ON.…”

Purpose Orthorexic tendencies are increasingly prevalent among children and adolescents. This study set out to investigate the reliability and validity of the Turkish version of the Orthorexia Nervosa Inventory (ONI) in a clinical adolescent sample. Methods 266 adolescents aged 12–18 years, who applied to the Department of Child and Adolescents Psychiatry were included in the study. Participants completed sociodemographic data form, ONI, Eating Attitude Test, Revised Child Anxiety and Depression Scale-Child Version and ORTO-15. Results The Cronbach’s alpha coefficient for the ONI reached 0.92, indicating very good internal consistency. Total factor scores and Cronbach alpha values for behaviors, impairments, and emotions were found to be 0.84, 0.84, and 0.83, respectively. The CFA performed supported the three-factor structure of the ONI obtained in the first sample. The minimum discrepancy per degree of freedom = 1.89 and the model generally fit well to the structure (RMSEA = 0.058, SRMR = 0.033, CFI = 0.92, TLI = 0.91). Discussion This study has shown that the Turkish version of the ONI is a valid and reliable scale for specifying the tendency for Orthorexia Nervosa in a Turkish adolescent population. These findings contribute in several ways to our understanding of orthorexic tendencies and provide a basis for more concrete research data that can be obtained by using the ONI, which is a reliable scale in studies to be conducted among adolescents. Level of evidence Level V, descriptive cross-sectional study.
