Evidence for construct validity of the TMJ scale in a sample of chronic post-traumatic headache patients.
The construct validity of the TMJ Scale was examined in a sample of chronic post-traumatic headache patients. Clinical indicators of temporomandibular (TM) dysfunction and measures of psychosocial distress were compared with relevant scales of the TMJ Scale. The clinical indicators were first subjected to principal components analysis. The resulting factor scores correlated significantly with selected physical domain scales of the TMJ Scale. The factor scores also significantly predicted the TMJ Global Scale in a regression analysis. Selected psychosocial domain scales of the TMJ Scale correlated strongly with measures of depression and anger and a clinical diagnosis of post-traumatic stress disorder. The results support the validity of the TMJ Scale and demonstrates its utility with post-traumatic headache patients.
