Bonding and bridging neighborliness: An individual-level study in the context of health

Although previous research provides a compelling picture of social capital's role in predicting health outcomes, only a modicum of research has tested the more detailed roles of the dimensions of bonding and bridging social capital, with no research focusing exclusively on bonding and bridging neighborliness or ethnicity. To help fill this gap in the literature, the current study measures individual-level bonding and bridging neighborliness for four U.S. ethnic groups—and then, with cross-sectional data from a 2007 national telephone survey of U.S. adults, employs ordinal logistic regression and OLS regression to test the individual-level predictors of self-rated health and stress, when controlling for BMI and demographics. Bonding neighborliness was associated with self-rated health and inversely associated with stress, whereas bridging neighborliness was not significantly linked to either health outcome. When also controlling for neighborhood composition, the bonding neighborliness findings remained generally consistent, while the association between bridging neighborliness and self-rated health gained significance. These results indicate the protective effects that bonding neighborliness can have on health outcomes, as well as the more modest protective effects of bridging neighborliness. These findings have implications for future research and practice, highlighting the potential of health interventions and policies that target the development of bonding social capital.
