Considerable empirical evidence substantiates the importance of social
networks and support to health and well-being among the elderly. But
considerably more research is necessary before successful intervention
s can be more generally implemented to positively alter an elder's net
work. In this article, the authors discuss social support and isolatio
n from an applied perspective. They have combined presentations origin
ally made at a National Institute on Aging-sponsored symposium on appl
ied gerontology held in August 1992. They make some general observatio
ns concerning the field of applied social relations in later life, des
cribe the mental health aspects of these relations, list some fundamen
tal principles and existing technology for this field, describe the us
e of a brief screening instrument for social isolation developed by on
e of the authors (Lubben), and explore varying domains of knowledge co
ncerning elder social relations. They conclude by outlining some areas
that they see as requiring the attention of an applications perspecti
ve to social support and isolation in the near future.
