Abstract

Purpose
This study aimed to evaluate the validity and reliability of the revised Korean version of the Chronic Hepatitis B Self-Management Scale-K16 (CHBSMS-K16).
Methods
Using the convenience sampling method, the data of chronic hepatitis B patients (N=200) were collected from August to October 2021. The participants were recruited from two hospitals in D metropolitan city and 3 internet cafes for hepatitis patients. The data were analyzed using SPSS 26.0 and AMOS programs. The content, structure, item-convergent/discriminant, and convergent validities and internal consistency were evaluated.
Results
Based on the statistical analysis, 9 items from the original version were excluded-resulting in 4 subscales with a total of 16 items. The confirmatory factor analysis demonstrated adequate model fit indices. The items convergence and discrimination validity were verified using extracted mean variance (.46~.65) and composition reliability (.81~.88). The convergent validity was satisfactory, as demonstrated by its correlation with the New General Self Efficacy scale (r=.63, p<.001). The Cronbach’s α for the overall scale was .88, and that of the four subscales ranged from .63 to .74.
Conclusion
The CHBSMS-K16 is a valid and reliable instrument. Therefore, this tool can be used to measure the level of self-management of Korean patients with chronic hepatitis B. Additionally, this scale can be used in clinical settings as well as in educational and research settings.
