Structural characteristics of social networks and their relationship with social support in the elderly: who provides...

The analyses presented here examine relationships between structural characteristics of social networks and two types of support (instrumental and emotional support) in a sample of community-dwelling individuals aged 65 and older. For each type of support, two dimensions are examined (1) the availability of such support and (2) the perceived adequacy of that support. Regression models, adjusting for age, sex, race and income show that structural characteristics such as total network size, number of face-to-face contacts and number of proximal ties are associated with greater availability of both instrumental and emotional support. The perceived adequacy of both types of support is most strongly related to the number of monthly face-to-face contacts. Comparisons of specific types of ties show that neither ones' spouse nor ones' children are primary sources of support. Rather the presence of a confidant is strongly associated with both dimensions of instrumental and emotional support; the presence of a spouse is not. And, while ties with children are most strongly related to aspects of instrumental support, ties with close friends and relatives are more strongly related to aspects of emotional support. Analyses of possible interactions show that for those without a spouse, confidants assume greater importance in providing emotional support. For those without children, ties with close friends and relatives assume a larger role relative to the perceived adequacy of both emotional and instrumental support.
