Abstract

OBJECTIVES
This study was conducted for evaluation of the reliability and validity of the Korean version of the Burden Assessment Scale (K-BAS).
METHODS
A sample of 256 first-order relatives of schizophrenics completed the K-BAS and the data were analyzed for internal consistency and factor structure. In addition, a subset of participants (n=112) refilled the K-BAS after two weeks for test-retest reliability. To test for validity, the Family Burden Scale (FBS), Korean version of Drug Attitude Inventory-10 (KDAI-10), and Korean version of the Scale to Assess Unawareness of Mental Disorder (SUMD-K) were administered.
RESULTS
The Cronbach's alpha coefficient of the K-BAS was high (0.91), which provided evidence for good internal consistency. The test-retest reliability of K-BAS was 0.86 (correlation coefficient, p<0.001). Convergent validity was examined through correlations between the K-BAS and the FBS (r=0.80, p<0.001). Divergent validity was examined through correlations between the K-BAS and KDAI-10 (r=-0.21, p=0.001), and between the K-BAS and SUMD-K (r=-0.02, p=0.796). Results of the factor analysis revealed a three-factor solution: activity limitation, social strain, and feelings of worry and guilt.
CONCLUSION
These results suggest that the K-BAS had good psychometric properties and may be a useful instrument for evaluation of burden of families with schizophrenics.
