Psychotherapists from the four primary mental health professions (counselors, psychiatrists, psychologists, and social workers) were surveyed regarding the ethicality of 83 psychotherapy-related behaviors. Results indicated a relatively high degree of consensus among psychotherapists of various disciplines regarding their ethical beliefs about the practice of psychotherapy. However, a significant effect for professional group was obtained on ethicality ratings of five psychotherapy behaviors (i.e., unintentionally disclosing confidential information, having clients take tests home, utilizing involuntary hospitalization, addressing a client by his or her first name, and having clients address the therapist by first name) with psychiatrists differing significantly from the other three mental health practitioner groups. The findings from the present study provide a descriptive database to assist practicing psychotherapists, state licensing and ethics boards, and professional organizations in determining what constitutes the ethical practice of psychotherapy.
