Objective: The aim of this study is to evaluate the validity and reliability of the Turkish version of the 'The Tampa Scale for Kinesiophobia for Temporomandibular Disorders (TSK-TMD)' questionnaire used to assess kinesiophobia in temporomandibular joint disorders.

Method: The "Tampa Kinesiophobia Scale in Temporomandibular Disorders" (TSK-TMD), which consists of 12 item, was adapted to Turkish with the translation and back-translation method. 111 patients (75 females, 36 males) who had been diagnosed with temporomandibular joint for at least 6 months and diagnosed as Temporomandibular Joint Disorder were participated to fill out the questionnaire. In the present study, participants were assessed with the Temporomandibular joint disorders evaluation form, Turkish TSK-TMD-12 item, Visuel Analogue Scale (VAS) and Pain Catastrophizing Scale (PCS). The internal consistency and test-retest reliability with a 3-5 days time were used to evaluate the reliability of the TSK-TMD. The reliability of the corelatıon was checked with PCS. Construct validity was assessed based on confirmatory factor analysis (CFA).

We used Turkish TSK-TMD-12 item, Visuel Analogue Scale (VAS) and Pain Catastrophizing Scale (PCS) questionnaires in our study.
