Stressful and positive family caregiving experiences were examined as predictors of caregivers' patterns of positive and negative affect in a sample of families providing care for a relative with dementia (N = 234). Four affect pattern groups were identified: (a) Well Adjusted (i.e., high positive affect, low negative affect); (b) Ambiguous (i.e., low on both positive and negative affect); (c) Intense (i.e., high on both positive and negative affect); and (d) Distressed (i.e., high negative affect, low positive affect). A multivariate model that included demographic characteristics and indicators of stressful and positive experiences of caregiving yielded 2 significant discriminant functions that served to classify caregivers correctly into their known affect groups. Implications for improving intervention efforts targeting family caregivers are discussed.
