Abstract
Purpose: This study aimed to examine the psychometric properties of a Turkish version of the ORTO-R scale by testing its factorial structure, reliability, and validity in a large adult population.
Methods: This cross-sectional study was conducted between November 2022 and February 2023. Through an online questionnaire, 1077 participants were recruited. Confirmatory factor analysis (CFA) was used to examine the construct validity of the questionnaires. The internal consistency of the ORTO-R scale was evaluated with Cronbach's alpha, Omega and test-retest coefficients. For the convergent and divergent validity of the scale, Pearson correlation analysis was performed on the scores of the Eating Attitude Test-26, the Generalized Anxiety Disorder-7 and the Life Satisfaction Scale.
Results: The two-factor model fit the data well. Analyses confirmed that the two-factor model of the ORTO-R had acceptable or good fit indices (χ 2/df = 2.126; GFI = 0.997; CFI = 0.992; AGFI = 0.992; TLI = 0.985; RMSEA = 0.032; SRMR = 0.029). According to the reliability coefficients, the orthorexia nervosa and method subscales were found to be reliable. The correlations supported the convergent and divergent validity of the scale.
Conclusions: The results demonstrate that the Turkish version of the ORTO-R is a valid and reliable instrument for assessing orthorexic behaviors in a theoretically meaningful way.
期刊介绍:
Eating and Weight Disorders - Studies on Anorexia, Bulimia and Obesity is a scientific journal whose main purpose is to create an international forum devoted to the several sectors of eating disorders and obesity and the significant relations between them. The journal publishes basic research, clinical and theoretical articles on eating disorders and weight-related problems: anorexia nervosa, bulimia nervosa, subthreshold eating disorders, obesity, atypical patterns of eating behaviour and body weight regulation in clinical and non-clinical populations.
