Reliability and validity of the Chinese version of the tampa scale of kinesiophobia in patients with total knee arthroplasty

Objective To evaluate the reliability and validity of the Chinese Version of the Tampa Scale of Kinesiophobia (TSK-11) in patients receiving total knee arthroplasty. Methods The Chinese version of TSK-11 was translated from the original one, and adjusted for cultural adaptation.The reliability and validity of Chinese TSK-11 were tested among 254 eligible patients receiving total knee arthroplasty from a tertiary hospital in Henan province by convenience sampling. Results Three common factors which explained 65.177% of the total variance was extracted after the exploratory factor analysis, and each item had high factor loading quantity (>0.4). The scale CVI was 0.83~1.00, the S-CVI/UA and S-CVI/Ave were 0.91 and 0.94, respectively.The Cronbach's α coefficient of the scale was 0.883, and the test-retest reliability was 0.798.The item-to-total correlations ranged from 0.424~0.757 (P<0.05). Conclusion The Chinese version of TSK-11 has been proved to be reliable and valid with fewer understandable items, and short completion time.It can be used as a valuable tool for evaluating kinesiophobia in patients following total knee arthroplasty.
