Purpose: The purpose of this study was to develop and test the validity and reliability of the Korean version of the expectations regarding aging(ERA-12) among middle-aged and elderly women.
Methods: The study was conducted as a cross-sectional survey which used a self-report questionnaire. A convenience sampling method was utilized, and data on 298 middle-aged and elderly women were collected. Korean version of ERA-12 was articulated through forward-backward translation methods. Internal consistency reliability, construct and criterion validity were analyzed using PASW WIN (20.0) for testing the use of Korean version of ERA-12.
Results: ERA-12 consisted of three factors - expectations regarding physical health, mental health and cognitive function, explaining 56.0% of the total variance in ERA-12. The ERA-12 total score showed positive correlation with RSES (r=.33). The Cronbach’s alpha reliability coefficient was .81 for the overall instrument and .68-.73 for three factors.
Conclusion: Korean version of ERA-12 has high validity and reliability. Therefore, this instrument may be utilized to assess expectations regarding aging for Korean middle-aged and elderly women.
