Clinicians are increasingly called to work with gay, lesbian, bisexual, and transgender (GLBT) youth, and yet little training is available on these issues. The goals of this Workshop are to review key competencies for working with GLBT youth and provide resources for those involved in training, supervision, and clinical care. The content areas covered include issues related to sexual orientation and gender identity among children, adolescents, and their parents. In this presentation the speakers include an in-depth discussion of the 11 practice principles included in the AACAP Practice Parameter on this topic, as well as a review of the current literature, clinical case vignettes, videos, and other teaching materials. Developing clinical competence in matters relevant to treating gender variant/GLBT youth in child and adolescent psychiatrists is feasible. Doing so, results in better addressing clinical needs of GLBT youth, a prevalent population.
