Korean Version of the Outcome Expectations for Exercise Scale-2: Validation Study
성인간호학회지, Vol.24(6) : 580~587, 2012
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 forwardbackward 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 ⍺ for the positive domain of outcome expectations for exercise scale-2 of .73. Negative domain, however, reported slightly low Cronbach’s ⍺ 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.
