Geriatric fear of falling measure: development and psychometric testing

Abstract

Development of the geriatric fear of falling measure (GFFM) was based on a previous qualitative study of Taiwanese community-dwelling elders. Relevant parameters or items for assessing subscales were identified and tested in a three-stage process: item development, content validity testing and reliability testing. The GFFM was tested on two groups of community-dwelling elders in Taiwan (N=100 and 384) to examine validity and reliability. Good test-retest, internal consistency and inter-rater reliability were found. Confirmatory factor analysis and good overall model fits supported construct validity of the GFFM. Although these data are preliminary, the GFFM could be used as a quick screening instrument to evaluate fear of falling and an outcome indicator of nursing interventions.
