It has been established that people from lower social classes tend to have poorer mental well-being compared with people from higher classes. Research also suggests that people from the lower classes are also less socially integrated. This research investigated the role of social integration in the relationship between social class and mental well-being across three studies (Study 1 N = 15,028; Study 2 N = 1,946; Study 3 N = 461). Across all studies, social class had an indirect effect on mental well-being via social integration. Moderation results found that social integration buffers the negative impact of financial issues on mental well-being, social support buffers the effects of class on mental ill-health, and family support amplifies rather than reduces social class differences in mental well-being. We propose that although improving social integration has the potential to improve the mental well-being of lower class populations, some caveats need to be considered.
