The "Guidelines for Psychological Practice With Lesbian, Gay, and Bisexual Clients" provide psychologists with (a) a frame of reference for the treatment of lesbian, gay, and bisexual clients and (b) basic information and further references in the areas of assessment, intervention, identity, relationships, diversity, education, training, and research. These practice guidelines are built upon the "Guidelines for Psychotherapy With Lesbian, Gay, and Bisexual Clients" (Division 44/Committee on Lesbian, Gay, and Bisexual Concerns Joint Task Force on Guidelines for Psychotherapy with Lesbian, Gay, and Bisexual Clients, 2000) and are consistent with the American Psychological Association (APA) "Criteria for Practice Guideline Development and Evaluation". They assist psychologists in the conduct of lesbian, gay, and bisexual affirmative practice, education, and research. (Contains 2 footnotes.)
