目的本研究评估了青少年九项回避/限制性食物摄入障碍 (ARFID) 筛查 (Y-NIAS) 在儿童临床样本中对饮食失调 (ED) 进行初步评估时的因子效度、发散效度和标准相关效度。方法参与者包括来自三级 ED 诊所的 310 名患者(82.9% 女性,77.4% 白人,年龄 = 14.65)。验证性因素分析(CFA)评估了 Y-NIAS 的三因素。单向方差分析比较了不同诊断的 Y-NIAS 评分。接受者操作曲线分析评估了每个分量表从完整样本中识别 ARFID 表现的能力。两个逻辑回归评估了所获得的 Y-NIAS 分数的标准相关有效性。结果 CFA 支持 Y-NIAS 的原始三因素结构。除暴食症外,所有诊断组均观察到临床评分升高。子量表无法将 ARFID 病例与其他 ED 诊断区分开来。确定了挑食子量表 (10) 和恐惧子量表 (9) 的削减分数,但没有确定食欲子量表的削减分数。与 ED 检查问卷 (EDE-Q) 结合,ARFID (62.7%) 和其他 ED (89.4%) 的分类准确度中等。讨论 Y-NIAS 表现出出色的因子效度和内部一致性。关于 Y-NIAS 在识别其他 ED 诊断中具有临床意义的 ARFID 表现方面的效用,结果好坏参半。
ObjectiveThis 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).MethodParticipants included 310 patients (82.9% female, 77.4% White, AgeM= 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.ResultsCFA 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%).DiscussionThe 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.
