Spirituality and psychological well-being: testing a theory of family interdependence among family caregivers and their elders.

The family spirituality-psychological well-being model was developed and tested to explore how spirituality influences psychological well-being among elders and caregivers in the context of Korean family caregiving. The sample consisted of 157 Korean elder-family caregiver dyads in Seoul, Korea. The intraclass correlation coefficient and the actor-partner interdependence statistical model were used to analyze the data. There were significant correlations between elders' and caregivers' spirituality and between elders' and caregivers' psychological well-being. Elders' and caregivers' spirituality significantly influenced their own psychological well-being. The caregiver's spirituality significantly influenced the elder's psychological well-being, but the elder's spirituality did not significantly influence the caregiver's psychological well-being. Findings suggest that elders' and caregivers' spirituality should be assessed within the family to provide holistic nursing interventions.
