Felt Age and Its Psychological Correlates in Dementia Spousal Caregiving Dyads: Findings From the IDEAL Programme.

Abstract

Evidence suggests spouses influence each other's subjective views on aging. Aligned with the Theory of Dyadic Illness Management, we investigated for the first time similarities in felt age (how old people feel relative to their chronological age) between people with dementia and their spousal caregivers, and how each partner's felt age was related to psychological correlates in the other partner. We used baseline (2014-2016) data from 1,001 people with dementia and their spousal caregivers who participated in the British Improving the experience of Dementia and Enhancing Active Life study. We ran linear regressions to analyze the extent to which the felt age of people with dementia and their caregivers were similar, and whether relationship quality was associated with the similarity. We utilized actor-partner interdependence models to analyze whether the felt age of people with dementia and their caregivers were associated with each other's well-being, satisfaction with life, and self-efficacy. The felt age of people with dementia was associated with the felt age of their caregivers (β = 0.10; p = .001). Caregivers and people with dementia reported a more similar felt age when caregivers rated the caregiving relationship more positively (β = 0.07; p = .04). Caregivers' felt age was associated with well-being (β = 0.07; p = .02) and satisfaction with life (β = 0.06; p = .04), but not with self-efficacy, in people with dementia. Felt age in caregivers and people with dementia may be interwoven, and important psychological variables in people with dementia are related to caregivers' felt age. Findings offer empirical evidence on dementia caregiving dynamics and how family relationships are related to views on aging.
