Translation and Psychometric Testing of the Fear of Falling Questionnaire-Revised in Community-Dwelling Older Adults

Falls pose a significant health risk to older adults, often resulting in adverse outcomes. Despite the recognition of effective interventions, the psychological aspect of fear of falling (FoF) remains under-addressed. The Fear of Falling Questionnaire-Revised (FFQ-R) (15 and 6-item) was developed to assess FoF. However, no Swedish version is available, necessitating its translation and evaluation of psychometric testing. This study aimed to translate the FFQ-R (15 and 6-item) and examine the psychometric properties of the Swedish versions in healthy community-dwelling adults aged ≥ 60 years.

This study used a cross-sectional design to translate and assess the psychometric properties of the FFQ-R(S) (15 and 6-item) for healthy community-dwelling older adults. Translators, experts, and community-dwelling older adults participated in the process. Confirmatory factor analysis was used to assess the fit of the model. Scale reliability was measured with ordinal α.

The translation resulted in minor changes and demonstrated satisfactory content validity. Confirmatory factor analysis showed that the FFQ-R(S) model, with four latent factors and 15 items, was not analyzable due to non-convergence. For the two-factors and six items, FFQ-R(S), the ordinal α values for the scales' harm outcome (HO) and degree of threat (DT), measuring reliability, were 0.70 and 0.88, respectively. The confirmatory factor analysis yielded mixed fit indices, where values of standardized root mean square residual, comparative fit index, and Tucker-Lewis index suggested a good fit of the model to the sample, whereas the χ² test and the value of root mean square error of approximation indicated a lesser good fit.

The Swedish version of the 6-item FFQ-R demonstrates acceptable psychometric properties. Moreover, the six items align with the two factors, DT and HO. Based on these findings, we recommend using the Short FFQ-R(S) (6-item) to assess FoF in primary fall prevention efforts for community-dwelling older adults.
