Cross-cultural adaptation, reliability, and validity of the Northern Thai version of the Tampa scale of kinesiophobia-17 in community-dwelling individuals with knee osteoarthritis

This study was designed to determine the validity and reliability of the northern Thai version of the TSK-17 in community-dwelling people with knee osteoarthritis (KOA). Participants with knee osteoarthritis living in Chiang Rai province were invited to participate in this study and were asked to complete the northern Thai version of the questionnaire. TSK-17 northern Thai version was administered twice with a seven-day interval, as was the Thai version of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Furthermore, the participants completed the Thai version of the medical outcomes study short-form survey version 2.0 (SF-36V2) and a timed-up and go test (TUGT). The findings revealed that 50 people took part in this study and completed the northern Thai version of the TSK-17 in five minutes. The TSK-17 northern Thai version demonstrated high internal consistency (α = 0.80) and test-retest reliability (ICC2,1 = 0.84). Convergent validity demonstrated a strong correlation with the Thai version of WOMAC (r = 0.70) and a weak correlation with the TUGT (r = 0.45). According to the findings of this study, the northern Thai version of the TSK-17 has acceptable validity and reliability for evaluating fear of movement in community-dwelling individuals with KOA.
