When primary and secondary caregivers disagree: predictors and psychosocial consequences.

The purpose of this study was to investigate primary caregiving spouses' and their lay helpers' divergent opinions about the caregiving environment. Through parallel assessments, both primary and secondary caregivers of a patient with Alzheimer's disease were asked to rate the degree of patient problem behaviors; the degree of strain the primary caregiver was experiencing; and primary care-giver efficacy, or perceived ability to cope with caregiving demands. Analyses concentrated on the general levels of disagreement in these domains, as well as on potential predictors and consequences of such disagreement. Results revealed a substantial divergence in perceptions across caregiving domains, with relatively less disagreement about patient problem behaviors and primary caregiver strain than about primary caregiver coping efficacy. Primary caregivers with relatively pessimistic secondary caregivers experienced relatively less psychosocial distress than primary caregivers with more optimistic helpers. These findings were strongest among female-female caregiving dyads. Theoretical implications and methodological limitations of the study are discussed, along with suggestions for future research.
