Social Networks Effects on Spouse and Adult-Child Dementia Caregivers' Experiences: A Cross-Sectional Study

Objectives: A large body of literature addresses experiences of spouse and adult-children caregiver of individuals with dementia (IWDs) but has not examined the role and strength of social networks in associations between spouses and adult-children caregivers' experience. Based on the stress process model, we aimed to explore the strength levels of social networks and their association with spouses/ adult-children caregivers for IWDs. Design: A cross-sectional study. Setting and Participants: A questionnaire-based survey was conducted with a total of 146 family caregivers of IWDs (78 adult-child, and 68 spouses) in China. Methods: Data collection comprised 4 sections: (1) care-related stressors (dementia stage, neuropsychiatric symptoms); (2) caregiver context; (3) social network, using the Lubben Social Network Scale; and (4) caregiving experience, using the short-form Zarit Burden Interview and 9-item Positive Aspects of Caregiving Scale. Linear regression, mediation model analysis, and interactive analysis were performed to explore the mechanisms of associations between variables. Results: Spouses had weaker social network strength (beta = -0.294, P =.001) and reported greater positive aspects of caregiving ( beta = 0.234, P =.003) than adult-children caregivers; no significant difference was found between them for caregiver burden. Mediation analysis suggests that associations between caregiver type and caregiver burden are indirect-only mediation effects of social networks ( beta = 0.140, 95% CI = 0.066-0.228). The social network strength suppressed the association between caregiver type and positive aspects of caregiving. The caregiver type/social network interaction statistically significantly (P =.025) affected the "positive aspects": a stronger social network was associated with more positive aspects of caregiving among the spouse subgroup (beta = 0.341, P =.003). Conclusions and Implications: Social networks mediate responses to caregiving experiences among different care provider types and are vital intervention targets, especially for spousal caregivers. Our results can serve as references for identifying caregivers for clinical intervention. (c) 2023 AMDA - The Society for Post-Acute and Long-Term Care Medicine.
