Avoidant/restrictive food intake disorder (ARFID) symptoms are prevalent among adolescents, yet no validated scale exists for Iran. This study evaluated the factor structure, measurement invariance, and prevalence of ARFID symptoms among adolescents at high risk for ARFID using the Farsi Nine-Item Avoidant/Restrictive Food Intake Disorder Screen (F-NIAS). Following translation and back-translation, 1,243 adolescents (75.9% girls) completed the F-NIAS. Confirmatory factor analysis confirmed the original three-factor structure with a good model fit. The scale demonstrated measurement invariance across sex, age, weight status, and residency, ensuring consistent performance across groups. Girls and younger adolescents showed higher ARFID symptoms than boys and older adolescents. Adolescents with average body mass index were more likely than those with higher weight to screen at high risk based on picky eating. Urban adolescents reported more low appetite-related restrictions. The F-NIAS is a valid scale for assessing ARFID symptoms in Iranian adolescents at risk for ARFID.
回避/限制性食物摄入障碍（ARFID）症状在青少年中很普遍，但伊朗尚无经过验证的量表。本研究使用波斯语九项回避/限制性食物摄入障碍筛查量表（F-NIAS）评估了ARFID高风险青少年中ARFID症状的因子结构、测量不变性和患病率。经过翻译和回译后，1243名青少年（75.9%为女孩）完成了F-NIAS。验证性因子分析证实了最初的三因子结构，模型拟合良好。该量表在性别、年龄、体重状况和居住地方面表现出测量不变性，确保了各群体间的一致表现。女孩和年龄较小的青少年比男孩和年龄较大的青少年表现出更高的ARFID症状。基于挑食，平均体重指数的青少年比体重较高的青少年更有可能筛查出高风险。城市青少年报告的与低食欲相关的限制更多。F-NIAS是评估有ARFID风险的伊朗青少年中ARFID症状的有效量表。
