The present research applied the investment model to the study of how gay, lesbian, bisexual, and transgender (GLBT) persons become committed to the broader community of sexual minorities. In addition, the present research examined the potential consequences associated with such commitment. In Study 1, satisfaction, investments, and alternatives each uniquely predicted an individual's commitment to the GLBT community. In Study 2, commitment to the GLBT community predicted higher levels of GLBT identification and stronger intentions to be involved in the community in the future. This research has important implications for understanding the factors that promote strong commitment to minority communities and how such commitment may play a vital role in facilitating social and political change for lower status groups.
