Validation of Igbo version of the modified falls efficacy scale among community-dwelling older adults: A validation study

Abstract

Background: Fear of falling (FOF) is a very pervasive problem among older adults. Consequently, many scales have been developed for its assessment. The Modified Falls Efficacy Scale (MFES) is one of the most popular FOF scales. The MFES was originally developed for use in developed countries, and thus may not be entirely suitable for use in developing countries due to cultural and environmental differences between the two country categories. This study was therefore designed to cross-culturally adapt and validate the MFES to Igbo culture and environment among community-dwelling older adults in Nnewi community using established guidelines. Methods: The original English version of the MFES (E-MFES) was translated, synthesized, back-translated, subjected to expert panel review, and pretested before producing the final Igbo version of the MFES (I-MFES). The I-MFES and the Short Falls Efficacy Scale International were randomly administered to consecutively recruited 109 consenting older adult residents of Nnewi (43.1% males; mean age = 74.45 ± 8.78 years). Convergent and structural validities and internal consistency of the I-MFES were assessed at 0.05 level of significance. Results: All the 14 items on the E-MFES were retained on the I-MFES. The I-MFES exhibited the same structure as the E-MFES. The correlation between the total scores on the I-MFES and the Short Falls Efficacy Scale International was excellent (rho = - 0.93) indicating evidence of convergent validity of the I-MFES. The Cronbach's alpha value of the I-MFES was 0.97 showing evidence of excellent internal consistency of the items on the I-MFES. Conclusion: This study provides evidence of some aspects of validity and reliability of the I-MFES.
