Objectives:
The aim of this study was to: (1) confirm the reliability and validity of a single factor structure for the 16-item FES-I within a Brazilian context; and (2) confirm the reliability and validity of the abbreviated Short FES-I (7 items) within a Brazilian context.
Methods:
We compared the reliability and construct validity of the unidimensional FES-I and the Short FES-I among older Brazilians. Our analyses included confirmatory factor analyses, and discriminatory validity and internal reliability consistency comparisons.
Results:
The unidimensional FES-I (α = 0.94; CFI = 0.98; RMSEA = 0.08) and the Short FES-I (α = 0.87; CFI = 0.98; RMSEA = 0.07) are equally valid and reliable measures.
Conclusion:
The FES-I is best represented as a unifactorial structure yielding a total Fear of Falling score. Researchers and healthcare professionals can also use the equally robust Short-FES-I to best minimize responder burden.
