Interconnected social convoys: Understanding health and well-being through linked personal networks.

The convoy model of social relations describes how social relationships contribute to an individual's health and well-being from a life course and lifespan perspective. In large part, this model focuses on the unique, personal experiences of an individual, without due consideration of the reciprocal and shared relationships among those whose lives are inextricably linked. Here, we extend the convoy model to directly integrate Elder's concept of linked lives by considering the composition, structure, and function of linked personal networks, or social convoys, among close others, and the important implications of these network characteristics on the health of all involved. We illustrate this extension within the context of family, one of the most pivotal social contexts that can shape an individual's life course. Features of interconnected social convoys can help improve our understanding of how social ties shape and are shaped by life events not just for individuals, but for larger units of inquiry - such as, couples, parent-child triads, and nuclear families. Importantly, the interconnected convoy includes both family and non-family ties, providing a framework that considers how peoples' social spheres are linked as they jointly experience shared situations. Using informal caregiving as an example, we highlight the advantages that interconnected convoys bring to the concept of linked lives and provide direction on how this framework can advance our understanding of how social relationships influence either directly or indirectly health and well-being of individuals and families across the life course.
