Abstract

Abstract: Background: The Fonseca anamnestic index (FAI) offers a simple, low‐cost, patient‐reported method for screening temporomandibular disorders (TMDs). Objectives: This study described the development of the Chinese version of the FAI (FAI‐C) and examined its reliability and validity when compared to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). Methods: The FAI‐C was created by translation and cross‐cultural adaptation of the English instrument following international guidelines. Psychometric evaluation of the FAI‐C was carried out on a sample of 613 patients with TMDs and 57 controls. Reliability of the FAI‐C was determined by means of internal consistency and test‐retest methods while validity was ascertained by criterion‐related validity. Criterion validity was examined via Cohen's kappa, sensitivity and specificity when compared with DC/TMD Axis I diagnoses. Results: Cronbach's alpha value (internal consistency) for total FAI‐C score was 0.669, and intra‐class correlation coefficient (ICC) value (test‐retest reliability) was 0.823. For criterion validity, kappa coefficient value was 0.633 while sensitivity and specificity was 95.9% and 71.9%, respectively. Conclusion: The Chinese version of the FAI demonstrated acceptable reliability and good validity. The FAI‐C could thus be used as an instrument for screening TMDs in Chinese literate populations.
