Abstract

PURPOSE
To develop and test the validity and reliability of the Korean version of outcome expectations-2 for exercise.
METHODS
The Korean version of outcome expectations for exercise-2 was developed through forward-backward translation techniques. Content, criterion, and construct validity using confirmatory factor analysis and an internal consistency reliability were conducted. Survey data were collected from 200 older adults living in a community.
RESULTS
The Korean version of outcome expectations for exercise-2 had factor loadings of the 13 items ranged from .20 to .76, and was validated by confirmatory factor analysis (CFI=.829, NFI=.754, RMSEA=.086). Also there was a reliable internal consistency with a Cronbach's alpha for the positive domain of outcome expectations for exercise scale-2 of .73. Negative domain, however, reported slightly low Cronbach's alpha of .63.
CONCLUSION
The findings of this study demonstrated that the Korean version of outcome expectations for exercise-2 had satisfactory validity to measure expectations regarding exercise among older adults in Korea. Negative domain, however, should be retested to verify reliability for the further study.
