Abstract

Purpose: To translate and cross-culturally adapt the English version of the SCI-SCS into Thai and assess its psychometric properties (validity and reliability). Methods: A cross-cultural adaptation of the preliminary SCI-SCS was performed using guidelines by Beaton et al. to create a Thai version of the SCI-SCS. Exploratory factor analysis (EFA) was used to analyze construct validity. Pearson’s correlation coefficient was used to analyze the convergent and discriminant validity against the Thai version of the World Health Organization Quality of Life-BREF scale (WHOQOL-BREF-Thai). Cronbach’s alpha was used to analyze the internal consistency of the total score and each domain. Intraclass correlation (ICC) was used to analyze the test-retest reliability. Results: A total of 160 participants were recruited from December 2023 to February 2024. The EFA suggested four components, with total variance accounting for 49.90%. The SCI-SCS Thai version was categorized into four domains and contained 16 items. There were significant moderate correlations, ranging from −0.32 to −0.46 between the SCI-SCS Thai version and WHOQOL-BREF-Thai. The ICC for the test-retest reliability was 0.94. Cronbach’s α was 0.79 for the total score ranged from 0.47 to 0.66 for each domain. Conclusion: The SCI-SCS Thai version was cross-culturally developed with acceptable validity and reliability.
