The term frailty is increasingly used in gerontological literature and in practice. However, indicators differentiating frail from nonfrail are not well delineated. Identifying factors discriminating between frail and nonfrail older community-residing adults may lead to more comprehensive clinical assessments and targeted interventions to minimize or prevent frailty. Eighty-four adults, ages 60 to 88 (mean = 74) living independently in the community completed a functional performance questionnaire and a perceived health questionnaire that were combined as measures of frailty. Predictor variables of frailty included four measures of balance and three measures of lower leg strength. Discriminant analysis revealed that one balance score and dorsiflexion correctly classified 65% of group membership, with better prediction of the nonfrail than frail group. This study clarifies that the predictors of frailty include the combination of dorsiflexion strength and balance, specifically the contribution of vision to balance when the support surface is compliant. Recommendations are proposed for conceptualizing and operationalizing frailty and adding variables to enhance discrimination between frailty and nonfrailty. Nursing implications include adding clinical assessments of specific components of balance and ankle strength to develop a more comprehensive evaluation of frailty.
