Program trainees of an interinstitutional interdisciplinary primary care-mental health training program, implemented in Houston, Texas, included residents in psychiatry, pediatrics, internal medicine, and family practice; medical students; and graduate students in psychology, social work and nursing. A combination of field practicum and didactic experiences encouraged interdisciplinary encounters. Social work trainee graduates were asked to complete a self-administered questionnaire rating 20 dimensions of the program in terms of usefulness to their present social work practice. Specific dimensions included interaction with peers and faculty by discipline and perceived value of their participation in the weekly didactic and case presentation components. Of 18 questionnaires mailed, 12 were returned. Students ranged in age from 24 to 56 (mean age of 34) and included 6 males and 6 females, with half being Hispanic. Mean rating student responses were used to examine in retrospect problems and issues encountered. Findings indicated peer interaction ratings ranged from a low of 5.67 for psychiatric nursing to a high of 8.00 for social work; faculty interaction ratings ranged from a low of 6.83 for psychiatry to a high of 7.66 for social work; and students felt the program positively affected their appreciation for their role as social workers, others' expertise, and their self-confidence.
