The Reliability and Validity of the Turkish Version of the Tampa Scale for Kinesiophobia for Temporomandibular Disorders

Abstract

Purpose The objective of this study to translate the Tampa Scale for Kinesiophobia for Temporomandibular Disorders (TSK-TMD) and to examine its reliability and validity. Material and Methods: The TSK-TMD was translated into Turkish as per international standards. The study included 111 patients with Temporomandibular Joint Disorder and, aged 18-61 years. The research questionnaire collected demographic information, the Turkish version of TSK-TMD and Pain Catastrophizing Scala (PCS). Using the intraclass correlation coefficient (ICC) and Cronbach's alpha coefficient, respectively, internal consistency and test retest reliability were examined. Construct validity was assessed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Results: The total Cronbach’s alpha coefficient was found to be 0.876. The item total correlation of was found to be between 0.410 and 0.706. The ICC coefficient was found to be 0.951. The correlation coefficient by PCS, measured in terms of parallel from reliability, was discovered to be 0.520. According to the findings of EFA and CFA, the 12-item scale had the same two-factor structure as the original. Conclusions: These results demonstrate the Turkish version of the TSK-TMD item questionnaire to be a valid and reliable instrument. It can be applied to patients with TMJ problems to assess kinesiophobia.
