Abstract
Objective
To develop and validate the Korea version of falls efficacy scale-international (KFES-I) in Korean elderly which was developed to assess fear of falling in older people and have been already validated in some European countries.
Method
Surveys of 385 older persons from the public health center in Korea based on KFES-I and fall questionnaire such as presence, frequency of fracture within last 6 months, and combined medical illness were taken. KFES-I was composed with 16 items of activities of daily living including social activities and graded from 1 to 4 in each item. Two-week KFES-I re-test data were collected. Reliability and validity estimates were computed as well as KFES-I sum scores according to age, sex, and falls history.
Results
Cronbach's alpha was 0.971 and mean inter-item correlation was 0.665. Test-retest Pearson correlation coefficient was 0.960 (p<0.01). As expected, KFES-I scores were associated with age, sex, and falls history (p<0.05). In addition, the KFES-I discriminated between sub-groups somewhat better than the original ten-item KFES scale.
Conclusion
KFES-I appears to be a reliable and valid method for measuring fear of falling in older adults. This study provides the preliminary evidence that KFES-I is a useful tool in evaluating Korean elderly who fear falling. (J Korean Acad Rehab Med 2010; 34: 554-559)
