Abstract
OBJECTIVES: The susceptibility of older adults' affect to fluctuations in their own health (within-person health sensitivity) indicates how they handle everyday health challenges. In old age, affective well-being is often increasingly influenced by close others, yet it is unknown whether older adults' affect is additionally susceptible to fluctuations in their spouse's health (within-partnership health sensitivity) and the extent to which age and relationship satisfaction moderate such associations.
METHODS: Parallel sets of multi-level actor-partner interdependence models are applied to self-reported health (feelings of pain/discomfort) and positive and negative affect, obtained 6 times a day over 7 consecutive days from two independent samples, the Berlin Couple Dynamics Study (N= 87 couples; Mage= 75 years; M relationship length= 46 years) and the Socio-Economic Panel Couple Dynamics Study (N= 151 couples; Mage= 72 years; M relationship length= 47 years).
RESULTS: Husbands and wives had lower positive affect and higher negative affect in moments when they reported more pain (within-person health sensitivity) and when their respective spouse reported more pain (within-partnership health sensitivity). Tests for moderation suggest that within-person, but not within-partnership, health sensitivity is lower at older ages and higher with more satisfying relationships.
DISCUSSION: These findings empirically illustrate lifespan notions that close relationships shape time-varying health-affect links and thus underscore the theoretical and practical utility of examining social contextual antecedents of older adults' everyday affective well-being.
