Maintenance of functional fitness is important for activities parallel to daily living (APDL) in older adults. The purpose of this study was to establish the functional fitness level sufficient for the achievement of APDL. For this purpose, the screening power of different thresholds of functional fitness score (FFS) was assessed using the receiver operating characteristics (ROC) curve. One hundred and ninety-two older community-dwelling women served as subjects (73.0±7.2yr). FFS was calculated using four functional fitness items (arm curl, walking around two cones, moving beans with chopsticks, functional reach) , and the level of achievement of APDL was evaluated by a questionnaire consisting of 16 questions. The sensitivity and false positivity rate of FFS as a screening threshold were analyzed within a cutoff range of -1.250 to 0.250, and the corresponding ROC curve was plotted to determine the threshold. The sensitivity ranged between 34.6% and 86.5%. The threshold showing the best equilibrium between sensitivity and specificity approached -0.375, where the sensitivity and false positivity rate were 63.6% and 3S.7%, respectively. When data from another questionnaire survey were analyzed to determine the criterion-related validity, a sensitivity of 61.9% and a false positivity rate of 32.2% were obtained. These results indicate that this threshold could provide useful information for the achievement of APDL.
