Supplementary Material for: Validation of an Arabic questionnaire to assess pediatric behavioral feeding disorders

Introduction: Behavioral feeding assessment allows for identifying the nature and the cause of abnormal feeding behaviors during mealtime, making prognostic predictions, and creating effective treatment plans. This study aimed to develop and validate an Arabic questionnaire to assess abnormal feeding behaviors among Arabic-speaking children. Methods: Mansoura Pediatric Eating Assessment Scale (MPEAS) was developed and administered to the parents of 100 Arabic-speaking children aged 1-5, including 50 typically developing children without feeding problems and 50 children with abnormal feeding behaviors. The scale includes 40 items in four subdomains (feeding skills, mealtime circumstances, child behavior, and parent behavior). Scoring was based on a 4-point Likert scale, with lower scores indicating greater impairment. Standardized procedures were used to develop and validate the MPEAS, including the items generation phase, pilot study, validation, and reliability testing. Results: MPEAS demonstrated excellent validity (face, content, discriminant, predictive, and convergent) and reliability. Conclusion: MPEAS is a valid, reliable, and easily applicable tool for assessing behavioral feeding problems in Arabic-speaking children. This sensitive and specific tool has the potential to significantly improve the screening and treatment of behavioral feeding problems among Arabic-speaking children, offering hope for better outcomes.引言：行为性进食评估可用于识别进餐期间异常进食行为的本质与成因，开展预后预测并制定高效治疗方案。本研究旨在开发并验证一款适用于阿拉伯语儿童异常进食行为评估的阿拉伯语问卷。方法：本研究开发了曼苏拉儿童进食评估量表（Mansoura Pediatric Eating Assessment Scale, MPEAS），并对100名1~5岁阿拉伯语儿童的家长进行施测，其中包含50名无进食问题的典型发育儿童，以及50名存在异常进食行为的儿童。该量表涵盖4个维度共40个条目，分别为进食技能、用餐环境、儿童行为与家长行为。评分采用4级李克特量表，得分越低提示功能受损程度越严重。MPEAS的开发与验证遵循标准化流程，涵盖条目生成阶段、预试验、效度验证与信度检验。结果：MPEAS展现出优异的效度（包括表面效度、内容效度、区分效度、预测效度与会聚效度）与信度。结论：MPEAS是一款有效、可靠且易于应用的评估工具，可用于阿拉伯语儿童的行为性进食问题评估。这款兼具高灵敏度与特异性的工具有望显著改善阿拉伯语儿童行为性进食问题的筛查与治疗工作，为实现更佳临床结局带来希望。
