Managed care has prompted a metamorphosis of mental health care. Since practitioners' responses to these changes are unclear, this study examines the opinions of 44 randomly selected psychologists and psychiatrists. Each participant received a packet in the mail that contained a cover letter, a three-page questionnaire, and a self-addressed stamped envelope. Questionnaire items were developed in conjunction with managed care providers. Items were seen as representative of concerns reflected in scientific journals, addressing issues such as utilization review, appeals, patient confidentiality, and short-term therapy. Respondents' median number of years of clinical experience was 18 and their mean number of years working in managed care was 5. Managed care's impact on the practices of psychologists versus psychiatrists was also examined. Most of the respondents, (57%) had Ph.D. level professional training while 17% held an M.D. Results revealed a strong negative attitude toward managed mental health care, particularly the utilization review process. However, despite this dissatisfaction, only a minority questioned utilization reviewers credentials. Participants also reported economic difficulties, such as a significant decline in referrals from primary care physicians. No strong attitudinal differences regarding managed care were revealed between Ph.D.s, M.D.s, and Master's level psychologists. Contains 19 references. (RJM)
