목적: Fear of falling is defined as the level of confidence in performing daily activities without falling. Increased fear of falling can lead to worsening of physical function, activity restriction and increased fall risk. The Falls Efficacy Scale-International (FES-I) is widely used to assess fear of falling. In this study, we aimed to examine reliability and validation of short form of FES-I as a screening tool in older population. 방법:Total of 155 subjects of 65 years of age and older were included in this study. Participants were asked to complete the questionnaire’s content included the KFES-I, scales of fall history and DHI. Age, sex, BMI, visual analog scale(VAS) of dizziness, comorbidities, differential diagnosis of dizziness and the history of falls in the past were collected from medical records and participant interview. Correlation analysis between the full 16-item KFES-I and the 7- item short form KFES-I results was performed. We also examined correlation between KFES-I and subjective perception of dizziness in patients presenting with dizziness. 결과:Mean score for long-form KFES-I was 29.18 ±12.77(range 16-59) and for short form, 12.67 ± 5.31(range 7-25). Comparison between the 16-item and 7-item KFES-I showed significant correlation. The KFES-I scores also showed significant correlation with dizziness handicap inventory (DHI) scores in patients with dizziness. Functional subscore (DHI-F) showed stronger correlation among subscores of DHI. 결론:The present study compared the Korean version of the 16-item and the 7-item short KFES-I with a population of patients with dizziness. The findings revealed that the original and short KFES-I scores were strongly correlated. Both scales displayed excellent internal consistency. The results also showed that the 16-item and 7-item KFES- I scores were associated with DHI of dizziness. The results support the possible application of the short form of FES- I to screen fear of falling in older adults, which can improve the feasibility of health screening. Further studies are needed investigate fear of falling in various etiologies of dizziness.
