Perceived social network support and well-being in same-sex versus mixed-sex romantic relationships

A theoretical model was tested, in which better perceived social network support specifically for a romantic relationship was hypothesized to predict higher relationship well-being which, in turn, would predict more positive mental and physical health outcomes for relationship partners. Furthermore, the model was tested on participants in both same-sex (i.e., homosexual, n = 183) and mixed-sex (i.e., heterosexual, n = 275) relationships. Structural equation modelling indicated that the hypothesized model did fit the data very well; furthermore, no differences in model fit were found between the two relationship groups. Support specifically for the relationship remained a highly significant predictor of the outcome variables, even when general social support and support for one's sexual orientation were controlled.
