Social ties and health status: an examination of moderating factors.

The goals of the study are to assess the relationship between social ties and health status and to determine if factors that may inhibit or enhance the mobilization of resources available in social ties specify this relationship. Two factors which may influence the effective use of social network resources perceived control and trusting others, are examined as possible moderating factors. The study population includes 2,603 adults, who were randomly selected from among the enrollees of a large health maintenance organization. The subjects were part of a large household interview survey. Medical record data covering seven years of outpatient services were linked with the survey data on the respondents. The findings indicate that having more social ties, being more trustful of others and perceiving more control are all related to having better health. Perceived control does specify the relationship between social ties and health status. The findings suggest that a larger social network is more important for those less able to utilize the resources available in their networks effectively, while among those more able to mobilize support from their networks, size is less important. The implications for health education research and practice are discussed.
