This study extends research on dimensions of sexual minority experience by examining differences between bisexual and lesbian/gay adults in adaptation to sexual orientation stigma. The authors investigated sexual orientation self-disclosure, connection to community, and 4 identity-related variables (internalized homonegativity, stigma sensitivity, identity confusion, and identity superiority) in a community sample of 613 lesbian, gay, and bisexual adults. Sexual orientation effects were found on 3 of these 6 variables: Bisexual participants reported higher levels of identity confusion and lower levels of both self-disclosure and community connection relative to their lesbian/gay peers. Taken together, the 6 variables predicted indicators of psychosocial functioning. Associations among the 6 dimensions of sexual minority experience and psychosocial functioning did not differ for bisexual and lesbian/gay participants.
