Purpose:
Many assessment tools have been proposed for use in clinical practice and research on individuals with temporomandibular disorders (TMD). It aimed to translate the Fonseca Anamnestic Index into Turkish (FAI/T) and examine the responsiveness, reliability and validity of the FAI/T in this study.
Materials And Methods:
Two hundred forty-nine individuals (207 female/42 male) with TMD were included in this study according to the RDC/TMD (muscle disorders, disc displacement, arthralgia and mixed disorders (muscle disorders and disc displacement)). Reliability was evaluated with test-retest reliability, internal consistency, and reproducibility. Validity was assessed with structural validity, construct validity, content validity, and face validity. In addition, responsiveness and floor and ceiling effects were also examined.
Results:
The ICC value (0.906) and Cronbach's α (0.951) of the (FAI/T) were excellent. Following Explarotary Factor Analysis, two factors were extracted, accounting for 51.859% of the total variation. Structural validity, construct validity, content validity, and face validity analyses proved the validity of the FAI/T. The responsiveness analysis showed that the Turkish FAI and its subscales were able to detect change over time.
Conclusions:
The FAI/T has shown excellent reliability and good validity. The FAI/T can assess the symptoms of Turkish-speaking persons with TMD.Clinical Trials registration number: NCT04274985.
