Informal Caregiving and Subjective Well-Being: Evidence of a Population-Based Longitudinal Study of Older Adults in Germany

Abstract

ObjectivesThe aim of this study was to examine whether informal caregiving affects subjective well-being (SWB) of the caregivers in the long run. MethodsThe German Ageing Survey (DEAS) is a nationwide, representative longitudinal study of community-dwelling individuals living in Germany aged 40 and older. The surveys in 2002, 2008, and 2011 were used (11,264 observations). Several components of SWB were used, covering functional and mental health, and affective (positive affect and negative affect) as well as cognitive well-being. Although functional health was quantified by the subscale “physical functioning” of the 36-Item Short Form Health Survey (SF-36), mental health was assessed by using the Center for Epidemiologic Studies Depression Scale (CES-D). Life satisfaction (cognitive well-being) was quantified by using the Satisfaction with Life Scale (SWLS) and positive and negative affect (affective well-being) was assessed using the Positive and Negative Affect Schedule (PANAS). ResultsLongitudinal regressions revealed that informal care affected (1) mental health in the total sample and in both sexes as well as (2) cognitive well-being in women. The effect of informal care on mental health was significantly moderated by self-efficacy in the total sample. ConclusionOur findings emphasize the role of informal caregiving for mental health and cognitive well-being (women). Moreover, our findings highlight the role of self-efficacy in the relation between informal care and mental health. Thus, to prevent declines in mental health due to informal care, it might be a fruitful approach to strengthen self-efficacy.
