Development and validation of a fall risk Questionnaire in Greek community-dwelling individuals over 60 years old.

Abstract

Objectives: The purpose of this study was to develop a questionnaire that can reliably recognize Greek individuals over the age of 60 with increased risk of falls.

Methods: An 11-item self-reported Questionnaire (LRMS) was developed and delivered to 200 individuals. Collected data were compared to Timed Up and Go (TUG), Falls Efficacy Scale-International (FES-I), Tinetti Assessment Tool, Geriatric Depression Scale-15 (GDS-15) and Morse fall scale. The results were statistically analyzed.

Results: Correlation between LRMS and the examined tools was high TUG (r=0.831), FES-I (r=-0.820), Tinetti balance (r=-0.812), Tinetti gait (r=-0.789), GDS-15 (r=-0.562), and Morse fall scale (r=0.795). Cronbach's alpha for LRMS total score was 0.807. ICC of the LRMS total score was 0.991. The area under the curve of LRMS was 0.930 (cut-off point 10.5, 95% C.I. 0.88 - 0.98, p<0.001, sensitivity=86%, specificity=98%) with TUG as gold standard, 0.919 (cut-off point 11.5, 95% C.I. 0.88 - 0.96, p<0.001, sensitivity=85%, specificity=89%) with FES-I and 0.947 (cut-off point 10.5, 95% C.I. 0.91 - 0.98, p<0.001, sensitivity=93%, specificity=91%) with Tinetti.

Conclusions: The LRMS Questionnaire showed sufficient internal consistency, excellent test-retest reliability and high correlation with the already established tools for fall risk assessment. It is short and easy to use without assistance from specially trained personnel.
