In this study, the authors investigated the degree to which perceived social support was associated with depression, life satisfaction, and internalized binegativity in a sample of 210 bisexual young adult college students. Two types of social support (general and sexuality specific) and 2 sources of social support (family and friends) were examined. Participants were recruited from the electronic mailing lists of organizations serving lesbian, gay, bisexual, and transgender students on 32 university campuses, and data were gathered via an Internet survey. Results indicated that general social support was most predictive of depression and life satisfaction, whereas sexuality-specific support was most predictive of internalized binegativity. Both family support and friend support contributed to the prediction of each of the outcome variables. Although it was expected that the link between friend support and positive adjustment would be strongest at low levels of family support, none of the interactions between friend and family support was statistically significant.
