A cross-sectional design investigated the physical attributes of 15 dyads of people with dementia and their caregivers. Physical and cognitive markers determined deviations from clinical thresholds for loss of functional independence, where 100% of participants performed below criterion-referenced threshold values for aerobic endurance. Walking distance for people with dementia was associated with bath/shower activity ( p  = .007), transfers ( p  < .001), and mobility ( p  = .013). Less distance walked was associated with more assistance with self-care tasks. Physical deficits associated with low aerobic endurance and lower body strength compromised independence, placing dyads at risk for falls and mobility-related health issues.

The measurement of the social construct of Family Quality of Life (FQOL) is a parsimonious alternative to the current approach of measuring familial outcomes using a battery of tools related to individual-level outcomes. The purpose of this study was to examine the internal consistency and concurrent validity of the International FQOL Survey (FQOLS-2006), using cross-sectional data collected from 65 family caregivers of children with developmental disabilities. It shows a moderate correlation between the total FQOL scores of the FQOLS-2006 and the Beach Center's FQOL scale. The validity of five FQOLS-2006 domains was supported by the correlations between conceptually related domains.
