In 1984, a task force of the American Psychological Association (APA) Committee on Lesbian and Gay Concerns was charged with investigating bias in psychotherapy with lesbians and gay men. The task force surveyed a large and diverse sample of psychologists to elicit information about specific instances of respondent-defined biased and sensitive psychotherapy practice. Open-ended responses were used to separately identify major themes of biased and sensitive practice and to illustrate each with concrete examples. Results suggest that psychologists vary widely in their adherence to a standard of unbiased practice with gay men and lesbians. To bring individual practice into accord with APA policy will require continued and expanded efforts to educate practitioners about sexual orientation.
