This study examined a model in which the relationship between social anxiety and two dimensions of ego identity (commitment and exploration) was expected to be mediated by social support and self-concealment for a sample of lesbian, gay, and bisexual individuals (N=347). Statistically significant paths were found from social anxiety to social support and self-concealment. Statistically significant paths were also found from social support to commitment, exploration, and self-concealment. There were no significant paths from social anxiety to commitment or exploration. Structural equation analyses and bootstrap procedures revealed support for the potential mediational role of social support in the association between social anxiety and the two dimensions of ego identity as well as in the link between social anxiety and self-concealment.
