OBJECTIVE: To determine the reliability and diagnostic accuracy of the Turkish version of the Fonseca anamnestic index (FAI-T). METHODS: The cultural equivalence of the FAI was established according to the International Network for Orofacial Pain and Related Disorders Methodology. The test-retest reliability, internal consistency, and diagnostic accuracy of the FAI-T was carried out in a sample of 66 controls and 139 patients with TMD. Diagnostic accuracy of the FAI-T was evaluated against the Research Diagnostic Criteria for Temporomandibular Disorders. RESULTS: Internal consistency analysis resulted in a Cronbach's alpha coefficient of 0.805. The intraclass correlation coefficient (ICC) values of each index question ranged from 0.739 to 0.897. FAI had a high level of accuracy (area under the ROC curve of 0.928). CONCLUSION: The results provide considerable evidence that the FAI-T can be used as a screening tool for the identification of TMD in Turkish-speaking populations.
