Currently, Oman lacks a valid culture-specific food frequency questionnaire (FFQ) for adults. This research aimed to develop and validate a reliable (FFQ) specifically for Omani adults. The study was conducted in two phases, employing both qualitative and quantitative methods. Phase 1 was the development of the (FFQ); in this phase the Diet History Questionnaire II (DHQ II) was adapted to develop the Omani Food Frequency Questionnaire (OFFQ), translated to the Arabic language, back-translated to English, pilot tested, and then refined to be used in the reliability study. Phase 2 was the reliability study, in this phase, the OFFQ was administered twice in Arabic with the second being filled one to two weeks after the first questionnaire. : A convenience sample of healthy Omani adults ( = 62) was recruited from Sultan Qaboos University (SQU) employees and students. To assess the reliability of the OFFQ both internal consistency and test-retest reliability were assessed. Internal consistency was assessed by conducting Cronbach's α test, while test-retest reliability was assessed by comparing the median intake of food groups by calculating weighted kappa (K) and intraclass correlation coefficients (ICCs). : Weighted kappa (K) between the two OFFQ administrations showed fair to moderate agreement with (K) values ranging from 0.38 to 0.60 for questions assessing the frequency of intake. While the median (K) values between the two OFFQ administrations ranged from 0.26 to 0.58 for questions assessing portion size. The majority of food groups showed moderate to good test-retest reliability with median (ICCs) for food groups ranging from 0.57 to 0.80 for frequency questions and from 0.40 to 0.82 for portion questions. : In conclusion, the newly developed OFFQ was deemed valid for the Omani dietary culture and is a reliable tool that can measure habitual dietary intake among Omani adults as evidenced by the reliability coefficients ranging from moderate to good agreement for the most food items and food groups. Future studies are warranted to assess the relative validity of the OFFQ and the inclusion of diverse demographic groups and a larger sample size.
目前，阿曼缺乏一份针对成年人的、有效的特定文化背景食物频率问卷（FFQ）。本研究旨在开发并验证一份专门针对阿曼成年人的可靠的食物频率问卷。该研究分两个阶段进行，采用了定性和定量方法。第一阶段是食物频率问卷的开发；在此阶段，对饮食史问卷II（DHQ II）进行了改编，以开发阿曼食物频率问卷（OFFQ），将其翻译成阿拉伯语，再回译成英语，进行预测试，然后进行完善，以便用于信度研究。第二阶段是信度研究，在此阶段，OFFQ以阿拉伯语进行了两次发放，第二次问卷在第一次问卷发放后的一到两周内填写。从苏丹卡布斯大学（SQU）的员工和学生中招募了62名健康阿曼成年人作为便利样本。为了评估OFFQ的信度，同时评估了内部一致性和重测信度。通过进行克朗巴哈α检验评估内部一致性，而通过计算加权kappa（K）和组内相关系数（ICC）来比较食物组的中位数摄入量来评估重测信度。两次OFFQ发放之间的加权kappa（K）显示出中等至良好的一致性，对于评估摄入频率的问题，K值范围为0.38至0.60。而对于评估份量大小的问题，两次OFFQ发放之间的中位数K值范围为0.26至0.58。大多数食物组显示出中等至良好的重测信度，食物组频率问题的中位数ICC范围为0.57至0.80，份量问题的中位数ICC范围为0.40至0.82。总之，新开发的OFFQ被认为适用于阿曼饮食文化，是一种可靠的工具，可以测量阿曼成年人的习惯性饮食摄入量，大多数食物项目和食物组的信度系数显示出中等至良好的一致性，这证明了这一点。未来的研究有必要评估OFFQ的相对效度以及纳入不同的人口群体和更大的样本量。
