The current study aimed to provide initial psychometric evidence for a Chinese version of the Nine-Item ARFID Screen (C-NIAS), which measures the symptoms of avoidant/restrictive food intake disorder (ARFID), including picky eating, poor appetite/limited interest in eating, and fear of aversive consequences from eating. The NIAS was translated into Chinese according to standard procedures. A total of 1,069 college students from mainland China responded to the C-NIAS. The factor structure was confirmed using confirmatory factor analysis. Convergent and divergent validity were assessed using regression analyses. Finally, measurement invariance was tested, and latent mean differences were compared, between Chinese and American college samples. The measure's original three-factor structure was confirmed. Strong measurement invariance between college samples of the United States and China was supported, and Chinese students had significantly higher latent mean scores on all three factors. The subscales showed the expected patterns of correlations with other validity constructs. The C-NIAS shows good psychometric characteristics and holds promise to facilitate much-needed research on subclinical symptoms of this understudied eating disorder in Chinese-speaking adult populations. Moreover, Chinese college students demonstrate greater potential ARFID symptomatology than American counterparts. More attention to ARFID should be called for in China.
本研究旨在为中文版回避/限制型进食障碍筛查问卷（C-NIAS）提供初步的心理测量学证据，该问卷用于评估回避/限制型进食障碍（ARFID）的症状，包括挑食、食欲差/对进食兴趣有限，以及对进食产生负面后果的恐惧。NIAS 是按照标准程序翻译成中文的。共有 1069 名来自中国大陆的大学生对 C-NIAS 做出了回应。使用验证性因子分析确认了因子结构。使用回归分析评估了聚合和发散效度。最后，对中美大学生样本进行了测量不变性检验，并比较了潜在均值差异。该测量的原始三因子结构得到了确认。支持美国和中国大学生样本之间的强测量不变性，中国学生在所有三个因子上的潜在均值得分显著更高。各分量表与其他有效性结构的相关性呈现出预期的模式。C-NIAS 具有良好的心理测量学特征，有望促进对中文成人人群中这种研究不足的进食障碍的亚临床症状的研究。此外，中国大学生表现出比美国大学生更大的潜在 ARFID 症状。中国应该更加关注 ARFID。
