The Turkish version of the Modified Falls Efficacy Scale: reliability and validity from the viewpoint of balance

BACKGROUND/AIM: The factors associated with fall-related self-efficacy should be addressed, especially in the elderly. The Modified Falls Efficacy Scale (MFES) is a simple instrument with good scaling properties and reliability. The aim of the present study was to determine the reliability and the validity of the Turkish version of the MFES from the viewpoint of balance. MATERIALS AND METHODS: In this study, 164 participants aged >65 years were included. The use of walking aids and assistive devices, history and frequency of falls in the previous year, living environment, and exercise habits were noted. Balance and risk of falling were assessed with the Berg Balance Scale (BBS). A forward-backward translation procedure was used for the Turkish version of the MFES. RESULTS: None of the 14 items in the MFES were modified. The Turkish version of the MFES has excellent internal consistency (Cronbach’s alpha, 0.978) and reliability (interclass correlation coefficient, 0.928–0.982), and its construct validity was supported by its ability to distinguish between the groups with respect to fall-risk factors and balance. According to the BBS scores, the high-fall-risk group had lower MFES scores than the moderate- and low-fall-risk groups (χ2 = 34.153, P = 0.001). CONCLUSION: The Turkish version of the MFES is a sensitive instrument for evaluation of fall-related confidence while carrying out indoor/outdoor activities. It also predicts falls, reduced physical activity, balance and mobility problems, and restricted social participation and daily living activities.
