Group supervision is widely used in clinical and counseling training sites but, until lately, has received minimal attention by researchers. Recent findings point to the possible benefits that process-oriented interventions may hold over a strictly task-focused style, yet this raises important ethical considerations. Currently, there is an insufficient body of research and literature addressing ethics in group supervision. Building on the template developed by K. S. Pope, B. G. Tabachnick, and P. Keith-Spiegel (1987, Ethics of practice: The beliefs and behaviors of psychologists as therapists, American Psychologist, Vol. 42, pp. 993-1006), 145 supervisees and 124 supervisors were surveyed on their beliefs and behaviors related to the ethical practice of group supervision. Results were organized around the themes of norms/structure, supervisee self-disclosure, client confidentiality, and multiple relationships. In most cases, there was remarkable consistency between the supervisors' and supervisees' responses, but in some important areas, the data yielded interesting contrasts. Similarly, for each of the samples, the likelihood that respondents engage in particular behaviors in group supervision typically matches their beliefs in the ethicality (or lack thereof) regarding those behaviors; but again, some discrepancies were present in these data. Implications for the field are discussed.
