The aim of this study was to validate the Farsi version of Rome III modular questionnaire which contains all functional gastrointestinal disorders (FGIDs).
We used Rome foundation guidelines for translation of English version into Farsi, and all the steps were performed. In the first step, 2 forward translations into Farsi were completed by two authors separately, and then translators, who participated in Step 1, together with our monitor, compared the two target-language versions and made some changes. The product of Phase 2 was translated back into English by an American-Iranian physician. The final step was comparison of the two English versions and validation of the translation. In this step, we compared the final version item by item, and also we used focus groups of patients after pretesting.
Our results showed that FGIDs questionnaire diagnosed 153 patients among 169 patients who were diagnosed to have different types of FGIDs. The sensitivity of this questionnaire was 90.5%. It was determined that the odd questions' values of Cronbach's alpha was 0.77 (very reliable), and it was 0.71 (very reliable) in other sections. The split-half test reliability of whole items value was 0.72, which is statistically significant.
Our findings showed that the Farsi version of Rome III diagnostic questionnaire for the adult functional gastrointestinal disorders demonstrated good validity and reliability and could be used in clinical studies.
本研究旨在验证包含所有功能性胃肠疾病（FGIDs）的罗马III型模块化问卷的波斯语版本。
我们采用罗马基金会指南将英文版翻译成波斯语，并完成了所有步骤。第一步，由两位作者分别完成两个波斯语的正向翻译，然后参与第一步的翻译人员与我们的监督员一起比较两个目标语言版本并进行了一些修改。第二阶段的成果由一位美籍伊朗医生回译成英语。最后一步是比较两个英语版本并验证翻译。在这一步中，我们逐项目比较最终版本，并且在预测试后使用了患者焦点小组。
我们的结果显示，FGIDs问卷在169名被诊断患有不同类型FGIDs的患者中诊断出153名。该问卷的敏感性为90.5%。确定奇数问题的Cronbach's alpha值为0.77（非常可靠），其他部分为0.71（非常可靠）。整个项目值的分半测试信度为0.72，具有统计学意义。
我们的研究结果表明，成人功能性胃肠疾病的罗马III型诊断问卷的波斯语版本具有良好的效度和信度，可用于临床研究。
