Psychiatric education improves internists' knowledge: a three-year randomized, controlled evaluation

Trainees were randomized into four groups: (1) control; (2) consult; (3) liaison; or (4) consult-plus-liaison to evaluate the psychiatric knowledge gained after two different training programs for primary care residents. Consult was a 1-month rotation on the Psychiatry Consultation Service. Liaison consisted of 31-hour workshops over 1 year. Consult-plus-Liaison refers to both training programs, experienced in consecutive years. An oral examination was administered before and after training. The analysis of variance and tests of simple effects revealed significant training effects for both groups. The effect size of training was greater for residents exposed to both programs, compared with either one alone. The two different training programs were both effective in improving the psychiatric knowledge of primary care residents and exposure to both programs proved superior to either one alone.
