Abstract

Objective: This study assessed the factorial, divergent, and criterion-related validity of the Youth-Nine Item Avoidant/Restrictive Food Intake Disorder (ARFID) Screen (Y-NIAS) in a paediatric clinical sample at initial evaluation for an eating disorder (ED). Method: Participants included 310 patients (82.9% female, 77.4% White, Age M = 14.65) from a tertiary ED clinic. Confirmatory factor analysis (CFA) evaluated the three-factor of the Y-NIAS. One-way analysis of variance compared Y-NIAS scores across diagnoses. A receiver operating curve analysis assessed the ability of each subscale to identify ARFID presentations from the full sample. Two logistic regressions assessed the criterion-related validity of the obtained Y-NIAS cut-scores. Results: CFA supported the original three-factor structure of the Y-NIAS. Clinically-elevated scores were observed in all diagnostic groups except for binge-eating disorder. Subscales were unable to discriminate ARFID cases from other ED diagnoses. Cut scores were identified for picky eating subscale (10) and Fear subscale (9), but not for Appetite subscale. In combination with the ED Examination Questionnaire (EDE-Q), classification accuracy was moderate for ARFID (62.7%) and other EDs (89.4%). Discussion: The Y-NIAS demonstrated excellent factorial validity and internal consistency. Findings were mixed regarding the utility of the Y-NIAS for identifying clinically-significant ARFID presentations from other ED diagnoses.
