Throughout the last two decades, attempts to measure orthorexia nervosa have been ongoing. The previous systematic review (Opitz et al., 2020) provided details on 10 distinct methods for orthorexia nervosa published in multiple languages (English, German, French, Dutch or Spanish), including the Body-Image Screening Questionnaire, the Burda-Orthorexia Risk Assessment, the Bratman Orthorexia Test, the Düsseldorf Orthorexia Scale, the Eating Habits Questionnaire, the Eating Habits Questionnaire-Revised, the Orthorexia Nervosa Scale, the ORTO-15, the Scale to Measure Orthorexia in Puerto Rican Men and Women, and the Teruel Orthorexia Scale. Despite this, a gold standard does not exist for the evaluation of orthorexia nervosa (Opitz et al., 2020). Nevertheless, the ORTO-15, the Eating Habits Questionnaire and the Düsseldorf Orthorexia Scale are the first and the most frequently used self-reported questionnaires for assessing orthorexia nervosa.
