Validação da Morse Fall Scale – versão brasileira para pessoas idosas institucionalizadas (MFS-B/ILPI)

Abstract

Abstract Objective To validate the criterion and construct of the Morse Fall Scale - Brazilian version (MFS-B) for institutionalized older adults. Method Methodological validation study nested within a longitudinal study. The research was conducted in two Homes for the Aged (ILPIs), involving 172 older individuals. Data were collected through direct assessment of the older adult and chart data. Analysis was performed using descriptive and inferential statistics including ROC curve, sensitivity, specificity, Pearson correlation, and Exploratory and Confirmatory Factor Analysis. Results The best estimate for predicting falls was at the cutoff point of 45 points on the MFS-B for institutionalized older adults, with a sensitivity of 93.3% and specificity of 58.9%. When analyzing the reliability of the MFS-B with the exclusion of the item "intravenous therapy/saline or heparin flush catheter" – "IV therapy/SHFC” reliability improved (α≥0.700), and this exclusion was also supported by Exploratory and Confirmatory Factor Analysis. Conclusions The results indicate a good predictive ability of the MFS-B for institutionalized older adults, with improved accuracy when excluding the item "IV therapy/SHFC". These findings supported the adaptation of the MFS-B to five assessment items, referred to as MFS-B/ ILPI.
