Cross-cultural adaptation and validation of the kinesiophobia causes scale: A descriptive survey have undergone total knee arthroplasty in China.

OBJECTIVE

The objectives of this study were to revise the Kinesiophobia Causes Scale (KCS) to make it suitable for Chinese cultural context and to verify its applicability in Chinese Total knee arthroplasty (TKA) patients.

METHODS

TKA patients in Henan Province, China (N = 418, average age ≥64 years). Exploratory and confirmatory factor analysis was performed on two samples randomly selected from the population (each N = 208). Psychometric properties, including the content, construct, predictive and concurrent validity was evaluated for KCS.

RESULTS

The KCS scale showed desirable internal consistency (Cronbach's alpha: 0.927), test-retest reliability (0.936), and content validity (0.958). A seven-factor structure was revealed and confirmed using exploratory and confirmatory factor analysis. The area under the curve was 0.852. The optimal cut-off score for KCS was 3.68.

CONCLUSIONS

The developed Chinese version of KCS is both reliable and valid when applied in Chinese setting of TKA patients.
