Reliability and Validity of the Cross-Culturally Adapted Thai Version of the Tampa Scale for Kinesiophobia in Knee Osteoarthritis Patients

PURPOSE: The aim of this study was to develop a cross-culturally adapted Thai version of the Tampa Scale for Kinesiophobia (TSK) and investigate its reliability and validity among patients with knee osteoarthritis. METHODS: The TSK was translated into Thai language and culturally adapted in line with the international standards. The Thai TSK questionnaire was then tested for internal consistency, test-retest reliability, and convergent validity by comparing it with the visual analogue scale, Western Ontario and McMaster Universities Osteoarthritis Index, State-Trait Anxiety Inventory, and Timed Up and Go Test. RESULTS: = 0.741, 0.856, and 0.817, respectively). However, there was no significant correlation between the Thai version of the TSK scores and the Timed Up and Go Test results. CONCLUSION: The Thai version of the TSK has satisfactory reliability and validity for the evaluation of pain-related fear of movement/(re)injury in patients with knee osteoarthritis.
