The purpose of this study was to test a barrier theory of perceived social
support to HIV-positive gay men. The proposed model was tested for friends
and family separately in order to investigate the uniqueness each provided.
In both models, it was hypothesized that the presence of barriers to socia
l support (availability, intimacy and disclosure) diminished acquisition of
social support. The influence of barriers on the relationship between soci
al support and health outcome (i.e. depression, t-cell count) for both frie
nd and family models was also investigated. In general, data from HIV-posit
ive gay men support barrier theory premises for both family and friends. Im
plications for helping professionals and researchers are proposed.
