The psychometric properties of the Indonesian FAI (FAI-I) and presence/severity of temporomandibular disorders (TMDs) among Indonesian young adults were explored.
The FAI-I was developed following the INfORM guidelines and used to determine the presence/severity of TMDs. Internal consistency/test-retest reliability were examined with Cronbach's alpha/intra-class correlation (ICC) coefficients. Construct/criteria validity were established by correlating (Spearman) the FAI-I to the five major TMD symptoms (5 Ts) and OHIP-14 (p < 0.05).
Five hundred-one participants (mean age 19.73 ± 1.27 years; 75.2% women) were recruited from a local University. Of these, 40.7% had no TMD, while 49.9%, 8.8%, and 0.6% had mild, moderate, and severe TMD. While Cronbach's α = 0.57 and ICC = 0.72, correlation coefficients to total 5 Ts and OHIP-14 were 0.53 and 0.47, respectively.
The FAI-I had low internal consistency, good test-retest reliability, and good validity. Moderate-to-severe TMD was experienced by 9.4% of the young adults examined.
