한국어판 낙상효능 척도와 활동 특이적 균형 자신감 척도의 타당도 및 신뢰도
The purpose of this study was to evaluate the applicability of the Korean version of Fall Efficacy scale(FES) and Activities-specific Balance Confidence Scale(ABC) to Korean older adult through an examination of instrument`s internal consistency and validity METHOD: A sample of 90 Korean older adults who lived in a community completed a survey instrument which included Korean version of FES and ABC. Because of comparable data derived from each scale, fear of falling and quality of life, activity daily living were included. Concurrent validity, criterion validity and correlational validity were tested. Reliability was tested by internal consistency, test-retest method.
Cronbach`s alpha was 0.9043 in FES, and 0.99623 in ABC. Test-retest correlations in all scales were higher than 7.0. Statistically significant association was found between fear of falling and both scales. Correlation coefficient between Quality of life(SF-8) and ABC was -0.142(p=0.049). Both FES and ABC are correlated significantly each other.
The Korean version of FES and ABC appears to be a reliable and valid method for meas- uring fear of falling. These instruments may be useful in assessing the independent contribution of fear of falling. ABC scale may be more useful to detect loss of balance confidence in more highly functioning seniors.
Key Words: FES(Fall Efficacy Scale), ABC(Activities-specific Balance Confidence Scale), Fear of Falling, Validity, Reliability
