Broken Bonds, Lonely Hearts? A Mediation Analysis of Childhood Adversity, Relationship Quality, and Loneliness in Later Life

OBJECTIVES: This study examined whether the link between adverse childhood experiences (ACEs, including child maltreatment, financial hardship, and household dysfunction) and later-life loneliness was mediated by quality of social relationships.

METHODS: Data came from the Health and Retirement Study ( N  = 11,700). Five path models were tested: four individual relationship types (spouse, children, relatives, and friends) and one combining all relationship types.

RESULTS: In the spouse model, child maltreatment and financial hardship increased loneliness via lower support and higher strain; household dysfunction showed no significant indirect effect. In the children and other relatives models, child maltreatment and financial hardship again showed significant indirect effects via lower support and higher strain, whereas household dysfunction had a small indirect effect via higher strain only. In the friendship model, only child maltreatment had a significant indirect effect on loneliness. In the combined model, child maltreatment was consistently associated with lower support and higher strain across relationship types, except for strain with friends.

CONCLUSIONS: ACEs increased loneliness partly by reducing social support and increasing social strain, with patterns varying by ACE and relationship type.

CLINICAL IMPLICATIONS: Loneliness interventions should address skills for rebuilding trust and supportive social ties.
