Main Article Content
Abstract
Background/Aims: In this study, we aimed to provide the usage of the Rome III criteria for irritable bowel syndrome (IBS) <span style="font-size: 12px;">in the healthcare field by conducting validity and reliability studies in Turkey and to facilitate diagnosis of these patients.</span>
Materials and Methods: Item analysis of the Rome III criteria was performed, and the test was applied to 79 <span style="font-size: 12px;">patients after their consistency had been validated with expert opinion. After the first application, the retest was </span><span style="font-size: 12px;">applied to 77 cases, and the consistency between the two applications was examined by kappa analysis. IBS was </span><span style="font-size: 12px;">diagnosed by expert opinion, which was accepted as ’the gold standard’.</span>
Results: Cronbach’s alpha of the Rome III criteria was calculated as 0.90. When the compliance between expert <span style="font-size: 12px;">assessment and IBS Rome III diagnostic criteria was compared, the diagnostic criteria’s sensitivity was determined </span><span style="font-size: 12px;">as 78.6%, and their specificity was 82.9%. When the Rome III criteria test-retest agreement was analysed, </span><span style="font-size: 12px;">the sensitivity, specificity and negative and positive predictive values of the Rome III diagnostic criteria were </span><span style="font-size: 12px;">determined as 97.4%.</span>
Conclusion: In this study, the internal consistency of the Rome III criteria for diagnosis of patients with IBS in our <span style="font-size: 12px;">country was found to be an important criterion because of the fact that the Rome III criteria have high internal consistency </span><span style="font-size: 12px;">and validation, they are a reliable measurement tool, they are able to distinguish IBS-positive and -negative </span><span style="font-size: 12px;">cases with the same rate as a specialist and their application is very easy.</span>
