The influences of optimal matching and social capital on communicating support.

The optimal matching and social capital perspectives frame present research expectations and interpretations of the network, esteem, informational, and emotional support communication of 3 computer-mediated communication social support groups, each having a different health-promoting purpose. Past research has shown differences in the support communication provided by different groups but has offered little explanation for these differences. The present study uses a comparative analysis of optimal matching and social capital influences to compare and analyze differences in the support communication provided by Alcoholics Anonymous, cancer caregivers, and transgender identity support groups. Results show different patterns of support communication enacted in each. These results provide support for optimal matching and social capital predictions, indicating that the life stressor and group structure affect the social support provided. However, results also demonstrate a need for greater refinement in interpreting the effects of these influences. Each group communicates network, esteem, informational, and emotional support somewhat differently in response to the life stressor and in enacting bridging and bonding social capital. The present comparisons provide a fuller analysis of the optimal matching and social capital influences upon the support communicated in groups than afforded by past research studies and suggests research opportunities for future research.
