Italian translation of the Nine-Item ARFID Screen (NIAS-IT) for ARFID surveillance in a dietetic service

Year: 2026

Type: article

Abstract: BACKGROUND: Several versions of the Nine-Item ARFID Screen (NIAS) have been developed in recent years to adapt the questionnaire to different languages and clinical samples. An Italian version is still lacking. From the perspective of a highly specialized Eating Disorder Unit in Milano, ARFID's phenomenology may be mimicked by other peculiar dietary habits or other eating disorders. Screening for this pathological conduct is necessary to assess a correct treatment frame for potentially serious disordered feeding behavior. METHODS: Clinical experts in Psychiatry, Psychology, and Dietetics collaborated in the translation process. The whole methodology involved several steps: (I) Italian translation; (II) backward translation from Italian to English; (III) assessing the conformity between the original English and retranslated questionnaires; (IV) testing the translated version on patients; (V) evaluating the degree of comprehensibility of the translated scale. KEY POINTS: The Italian version of the NIAS (NIAS-IT) was administered online to 23 consecutive outpatients of a Dietetic department. For the most part, the sample of Italian native speakers found the translated version of the questionnaire to be comprehensible and easy to read. CONCLUSIONS: The Italian version of the NIAS is perfectly comprehensible and can be applied to the Italian population for both clinical and research purposes. LEVEL OF EVIDENCE: Level IV, evidence obtained from multiple time series with or without intervention.
