SOCIAL CAPITAL AND HEALTH CARE ACCESS: A SYSTEMATIC REVIEW

Abstract

A growing interest in community-level characteristics such as social capital and their relationship to healthcare access is evident. To assess the rigor with which this construct has been empirically applied in research on healthcare access, we conducted a systematic review. A total of 2396 abstracts were reviewed, with 21 ultimately meeting our criteria of examining some measure of social capital and its effects on healthcare access. Our review found a lack of congruence in how social capital was measured and interpreted and a general inconsistency in findings, which made it difficult to draw firm conclusions about the effects of social capital on healthcare access. Insights from the social network literature can help improve the conceptual and measurement problems. We recommend that future work distinguish between bonding, bridging, and linking social capital and their sources and benefits, and that perhaps three dimensions of social capital actually exist –cognitive, behavioral, and structural.
