Behavioral symptoms of dementia: a dyadic effect of caregivers' stress process?

This study used multilevel modeling to evaluate a newly revised model in which dementia caregivers' stress process variables-perceived stress and emotional-behavioral responses-were posited as predictors of behavioral symptoms of dementia (BSD) within community-based dyads. Secondary analyses were conducted on data from a primary two-group (experimental and control) trial, in which experimental participants received a home monitoring system for managing nighttime activity in individuals with dementia. Models indicated that caregivers' trajectories did not differ significantly between groups over time; however, the time-by-group interaction of BSD approached significance.
