BACKGROUND/AIMS: A self-report questionnaire is frequently used to measure symptoms reliably and to distinguish patients with functional gastrointestinal disorders (FGIDs) from those with other conditions. We produced and validated a cross-cultural adaptation of the Rome III questionnaire for diagnosis of FGIDs in Korea.
The Korean version of the Rome III (Rome III-K) questionnaire was developed through structural translational processes. Subsequently, reliability was measured by a test-retest procedure. Convergent validity was evaluated by comparing self-reported questionnaire data with the subsequent completion of the questionnaire by the physician based on an interview and with the clinical diagnosis. Concurrent validation using the validated Korean version of the Short Form-36 Health Survey (SF-36) was adopted to demonstrate discriminant validity.
A total of 306 subjects were studied. Test-retest reliability was good, with a median Cronbach's α value of 0.83 (range, 0.71-0.97). The degree of agreement between patient-administered and physician-administered questionnaires to diagnose FGIDs was excellent; the κ index was 0.949 for irritable bowel syndrome, 0.883 for functional dyspepsia and 0.927 for functional heartburn. The physician's clinical diagnosis of functional dyspepsia showed the most marked discrepancy with that based on the self-administered questionnaire. Almost all SF-36 domains were impaired in participants diagnosed with one of these FGIDs according to the Rome III-K.
We developed the Rome III-K questionnaire though structural translational processes, and it revealed good test-retest reliability and satisfactory construct validity. These results suggest that this instrument will be useful for clinical and research assessments in the Korean population.
背景/目的：自陈式问卷常用于可靠地测量症状，并将功能性胃肠疾病（FGIDs）患者与其他疾病患者区分开来。我们制作并验证了用于韩国 FGIDs 诊断的 Rome III 问卷的跨文化适应性。
通过结构翻译过程开发了 Rome III-K 问卷。随后，通过测试-重测程序来测量可靠性。通过将自我报告的问卷数据与医生根据访谈完成的后续问卷以及临床诊断进行比较来评估收敛有效性。采用经过验证的韩国版 SF-36 健康调查短表（SF-36）进行同时验证，以证明判别有效性。
共研究了 306 名受试者。测试-重测可靠性良好，Cronbach's α 值中位数为 0.83（范围为 0.71-0.97）。患者自行管理和医生管理的问卷诊断 FGIDs 的一致性程度非常高；肠易激综合征的κ指数为 0.949，功能性消化不良为 0.883，功能性烧心为 0.927。功能性消化不良的医生临床诊断与基于自我管理问卷的诊断差异最大。根据 Rome III-K，几乎所有 SF-36 领域在被诊断为这些 FGIDs 之一的参与者中都存在受损。
我们通过结构翻译过程开发了 Rome III-K 问卷，它显示出良好的测试-重测可靠性和令人满意的结构有效性。这些结果表明，该工具将对韩国人群的临床和研究评估有用。
