Abstract
A theory of lesbian, gay, bisexual, and transgender (LGBT) ally identity development integrated the following theories—multicultural counseling theory (MCT), self-concept formation theory (SCFT), and social identity theory (SIT)—to design a course to train heterosexual students to be allies to LGBT communities. Students participated in interviews and activities with LGBT persons, presented seminars on LGBT topics, and wrote papers about these experiences. An analysis of their reactions suggested that initially, students perceived themselves as lacking credibility to be allies. After interacting with LGBT communities, students gained the knowledge, attitudes, and skills they needed to be confident in supporting and advocating for LGBT persons.
