BACKGROUND/AIMS: In this study, we aimed to provide the usage of the Rome III criteria for irritable bowel syndrome (IBS) in the healthcare field by conducting validity and reliability studies in Turkey and to facilitate diagnosis of these patients.
Item analysis of the Rome III criteria was performed, and the test was applied to 79 patients after their consistency had been validated with expert opinion. After the first application, the retest was applied to 77 cases, and the consistency between the two applications was examined by kappa analysis. IBS was diagnosed by expert opinion, which was accepted as 'the gold standard'.
Cronbach's alpha of the Rome III criteria was calculated as 0.90. When the compliance between expert assessment and IBS Rome III diagnostic criteria was compared, the diagnostic criteria's sensitivity was determined as 78.6%, and their specificity was 82.9%. When the Rome III criteria test-retest agreement was analysed, the sensitivity, specificity and negative and positive predictive values of the Rome III diagnostic criteria were determined as 97.4%.
In this study, the internal consistency of the Rome III criteria for diagnosis of patients with IBS in our country was found to be an important criterion because of the fact that the Rome III criteria have high internal consistency and validation, they are a reliable measurement tool, they are able to distinguish IBS-positive and -negative cases with the same rate as a specialist and their application is very easy.
背景/目的：在本研究中，我们旨在通过在土耳其进行有效性和可靠性研究，提供罗马III标准在肠易激综合征（IBS）医疗领域的应用情况，以促进这些患者的诊断。
对罗马III标准进行项目分析，并在经专家意见验证其一致性后，将该测试应用于79例患者。首次应用后，对77例患者进行重新测试，并通过kappa分析检查两次应用之间的一致性。IBS由专家意见诊断，专家意见被视为“金标准”。
计算得出罗马III标准的Cronbach's alpha为0.90。比较专家评估与IBS罗马III诊断标准之间的符合率时，诊断标准的敏感性为78.6%，特异性为82.9%。分析罗马III标准的重测一致性时，罗马III诊断标准的敏感性、特异性以及阴性和阳性预测值均为97.4%。
在本研究中，我国用于诊断IBS患者的罗马III标准具有较高的内部一致性和有效性，是一种可靠的测量工具，能够以与专家相同的比率区分IBS阳性和阴性病例，且应用非常简便，因此其内部一致性被认为是一个重要标准。
