Abstract
This theory synthesis provides a theoretical model for nursing researchers to examine factors that influence resilience and burden in family caregivers of individuals with opioid use disorder. Two frameworks, the Resiliency Model and the Conceptual Framework for Family Involvement with Adults with Co-occurring Substance and Mental Disorders, were synthesized and modified by incorporating concepts and conceptual relationships from recent research studies and experiential knowledge from clinical practice to develop a new model. The model predicts the impact of caregiver characteristics, caregiver support, stressors, and caregiver-care recipient dyad characteristics on caregiver well-being.
