回避/限制性食物摄入障碍（ARFID）是一种以营养或热量摄入不足为特征的饮食或喂养障碍，导致体重减轻、营养缺乏、补充剂依赖和/或严重的社会心理障碍。DSM-5列出了可能导致ARFID症状的三种不同的饮食模式：由于食物的感官特性（例如，挑食）而避免食物，食欲不振或对饮食的兴趣有限，或害怕饮食的负面后果。由于缺乏有效的工具来测量这些饮食行为，ARFID的患病率和精神病理学研究受到限制。本研究描述了九项ARFID筛查（NIAS）的开发和验证，这是一种简短的多维工具，用于测量ARFID相关的饮食行为。参与者是在亚马逊的土耳其机器人上招募的455名成年人，从全国代表性学科中招募的505名成年人，以及参加课程学分研究的311名本科生。探索性和验证性因素分析提供了三个因素的证据。NIAS子量表具有较高的内部一致性、重测信度、两样本间不变的项目负荷，以及与挑食、食欲、对负面后果的恐惧和精神病理等其他测量的收敛/判别效度。这些量表也与arfid样症状（例如，低BMI，低水果/蔬菜种类和摄入量，以及饮食相关的社会心理干扰/困扰）的测量相关，尽管挑食，食欲和恐惧量表与这些结构有明显的独立关系。NIAS是一种简短、可靠的工具，可用于进一步调查arfid相关的饮食行为。(C) 2017 Elsevier Ltd.版权所有。
Avoidant/Restrictive Food Intake Disorder (ARFID) is an eating or feeding disorder characterized by inadequate nutritional or caloric intake leading to weight loss, nutritional deficiency, supplement dependence, and/or significant psychosocial impairment. DSM-5 lists three different eating patterns that can lead to symptoms of ARFID: avoidance of foods due to their sensory properties (e.g., picky eating), poor appetite or limited interest in eating, or fear of negative consequences from eating. Research on the prevalence and psychopathology of ARFID is limited by the lack of validated instruments to measure these eating behaviors. The present study describes the development and validation of the nine-item ARFID screen (NIAS), a brief multidimensional instrument to measure ARFID-associated eating behaviors. Participants were 455 adults recruited on Amazon's Mechanical Turk, 505 adults recruited from a nationally-representative subject pool, and 311 undergraduates participating in research for course credit. Exploratory and confirmatory factor analyses provided evidence for three factors. The NIAS subscales demonstrated high internal consistency, test-retest reliability, invariant item loadings between two samples, and convergent/discriminant validity with other measures of picky eating, appetite, fear of negative consequences, and psychopathology. The scales were also correlated with measures of ARFID-like symptoms (e.g., low BMI, low fruit/vegetable variety and intake, and eating-related psychosocial interference/distress), although the picky eating, appetite, and fear scales had distinct independent relationships with these constructs. The NIAS is a brief, reliable instrument that may be used to further investigate ARFID-related eating behaviors. (C) 2017 Elsevier Ltd. All rights reserved.
