Cross-Cultural Adaptation, Reliability, and Validity of the Chinese Version of the Tampa Scale for Kinesiophobia-11 Among Patients Who Have Undergone Total Knee Arthroplasty.

Abstract

BACKGROUND\nThe shortened version of the Tampa Scale for Kinesiophobia (TSK-11) has been well characterized in the literature. However, to the best of our knowledge, no previous studies have evaluated the reliability and validity of the TSK-11 for Chinese-speaking patients who have undergone total knee arthroplasty (TKA). Thus, the objectives of this study were to translate and adapt the TSK-11 cross-culturally into Chinese and to evaluate its reliability and validity in a sample of Chinese TKA patients.\n\n\nMETHODS\nThe TSK-11 was translated and cross-culturally adapted into Chinese according to the international guidelines for the cross-cultural adaptation of self-report measures. The Chinese version of TSK-11 was administered to 254 patients following their TKA, along with the Fear-Avoidance Beliefs Questionnaire, Pain Catastrophizing Scale, Numerical Rating Scale, and 12-Item Short Form Health Survey. Psychometric testing included internal consistency, test-retest reliability, floor and ceiling effects, construct validity, and convergent validity.\n\n\nRESULTS\nA high completion rate of 95.8% with no floor or ceiling effects was noted in the Chinese version of the TSK-11. The questionnaire also showed good internal consistency (Cronbach s α\xa0= 0.883) and test-retest reliability (intraclass correlation coefficient\xa0= 0.798). Construct validity was assessed by exploratory factor analysis, and 3 factors were extracted that accounted for 65.2% of the variance. Convergent validity was confirmed by significant Pearson correlations between the Chinese version of the TSK-11 and the Pain Catastrophizing Scale (r\xa0= 0.751), Fear-Avoidance Beliefs Questionnaire (r\xa0= 0.719) and VAS (r\xa0= 0.450), as well as the 12-Item Short Form Health Survey subdomains Bodily Pain (r\xa0=\xa0-0.391), Mental Health (r\xa0=\xa0-0.356), Physical Functioning (r\xa0=\xa0-0.339), Role-Emotional (r\xa0=\xa0-0.317), and Role-Physical (r\xa0=\xa0-0.277).\n\n\nCONCLUSION\nThe Chinese version of the TSK-11 demonstrated satisfactory acceptability, reliability, and validity; therefore, it can be used in clinical practice and research for assessing kinesiophobia in Chinese patients after TKA.
