Excessive sugar consumption is a growing public health concern, with research suggesting it may function as an addictive substance. However, the lack of standardized tools to assess sugar addiction, particularly across cultures, remains a challenge. This study aims to validate the Persian version of the Sugar Addiction Questionnaire (SAQ) for use in Iran. In this cross-sectional psychometric validation study, 504 Persian-speaking adults (59.1% female, mean age = 29.8 ± 19.5 years) were recruited using convenience sampling from Tehran health centers. Participants completed the SAQ and Yale Food Addiction Scale (YFAS 2.0), and participated in DSM-5-based semi-structured interviews for sugar addiction. Factor analysis and reliability measures (Cronbach's alpha, test-retest, split-half) were used to assess the SAQ's validity and reliability. The Persian SAQ demonstrated strong psychometric properties. Factor analysis revealed a five-factor structure explaining 45.08% of the variance. Concurrent validity was confirmed by significant correlations with the YFAS 2.0 (r = 0.51, P < 0.001) and BMI (r = 0.55, P < 0.001). The scale showed a good model fit (CFI = 0.91, RMSEA = 0.08), with acceptable reliability (Cronbach's alpha = 0.79) and a test-retest correlation of 0.54. The optimal cutoff for diagnosing sugar addiction was 9, with the Area-Under-the-Curve (AUC) of 98%. The Persian version of the SAQ is a reliable and valid tool for assessing sugar addiction in Iran. This validated instrument can improve the diagnosis and understanding of sugar-related behavioral issues, supporting better public health strategies for managing excessive sugar consumption.
过量摄入糖分正日益引起公众对健康的担忧，研究表明糖可能是一种成瘾物质。然而，缺乏标准化的工具来评估糖成瘾，尤其是跨文化评估，仍然是一个挑战。本研究旨在验证用于伊朗的波斯语版糖成瘾问卷（SAQ）。
在这项横断面心理测量学验证研究中，采用便利抽样法从德黑兰的健康中心招募了504名讲波斯语的成年人（女性占59.1%，平均年龄 = 29.8 ± 19.5岁）。参与者完成了SAQ和耶鲁食物成瘾量表（YFAS 2.0），并参加了基于《精神疾病诊断与统计手册》第5版的糖成瘾半结构化访谈。采用因子分析和可靠性测量（克朗巴哈系数、重测法、分半法）来评估SAQ的有效性和可靠性。
波斯语版SAQ显示出很强的心理测量学特性。因子分析揭示了一个五因素结构，解释了45.08%的方差。与YFAS 2.0（r = 0.51，P < 0.001）和BMI（r = 0.55，P < 0.001）的显著相关性证实了同时效度。该量表显示出良好的模型拟合度（CFI = 0.91，RMSEA = 0.08），具有可接受的可靠性（克朗巴哈系数 = 0.79），重测相关性为0.54。诊断糖成瘾的最佳临界值为9，曲线下面积（AUC）为98%。
波斯语版SAQ是评估伊朗糖成瘾的可靠且有效的工具。这一经过验证的工具可以改善对与糖相关行为问题的诊断和理解，支持更好地管理过量糖分摄入的公共卫生策略。
