A study was carried out in a group of 91 HIV positive gay men to inves
tigate the relationship between social support, measures of affect and
health; the changing nature of support over time; and the causal dire
ction of this relationship. Overall levels of support for this group w
ere found to be moderately high and consistent over 6 months and were
associated with greater psychological well-being. Individuals in recei
pt of quantitatively different levels of support were found to differ
on measures of depression, stress, coping efficacy and self-esteem, wh
ile individuals in receipt of deficient levels of support were found t
o be more depressed. However, initial support levels were found to be
the most powerful predictors of subsequent support levels. The implica
tions of these findings are discussed.
