In- and out-Group Trust and Self-Rated Health: A Multi-Country Analysis
Using data from 56 countries in the sixth wave of the World Value Survey, I found the relative advantage of in-group trust than out-group trust in its association with self-rated health. In contrast, out-group trusters reported better health only in Western societies. These findings suggest that (a) using distinct measures of in- and out-group trust show more straightforward and detailed trust-health relationship in cross-national studies, and (b) in-group trust may generate health advantages such as receiving timely support from confidants and having sense of attachment to primary groups against distress. On the other hand, (c) out-group trust is beneficial to health exclusively in the West where relatively a high level of civic awareness and associational activities enables out-group trusters to get necessary health assistance from people beyond their in-group boundaries.
