Using data from the National Medical Expenditure Survey, a household survey of more than 18,000 respondents, this study examined racial and gender differences in social embeddedness, an indicator of community well-being and social support. The study hypothesized that higher levels of social embeddedness would be found among African Americans than among Whites and that the association between social embeddedness and psychological well-being would be stronger among African Americans than among Whites. African American men reported themselves more socially embedded overall than White men and, in one instance, their social involvement was especially important in predicting psychological well-being. African American women were more likely than White women to report attending meetings of churches and community groups, but otherwise were less socially involved than White women. There was no evidence of a difference between African American and White women in strength of the connection between social embeddedness and psychological well-being. African American social involvement is more selective than previously believed and generalizations must be qualified on the basis of gender.
