The beneficial effects of social support on well-being have been shown in various studies. Less is known about factors which constrain or enhance the availability of social support. The present study profiles social support among women veterans and attempts to identify factors which enhance or constrain perceptions of support and social integration for women of different military eras. Data are derived from a national sample of women veterans who had at least one VA out-patient visit during a one year time period. Twenty percent of women veterans report having no one to depend on. Social support is lowest among Vietnam and Post-Vietnam era women. Chronic strains (such as having problems with relatives, housing, and paying bills) are important factors which are associated with levels of perceived support. Factors related to loneliness/alone status appear to be associated with constraints in group activities and perceived support. This research illustrates the importance of examining factors which constrain and enhance supportive activities and relationships.
