The authors compared data on 2,860 residents gathered by means of
questionnaire responses by residency directors with data on 288 residents
found in an earlier similar survey to have emotional difficulties. They
found that age, marital status, previous psychiatric treatment, substance
abuse, and previous nonpsychiatric medical practice differentiated the
"problem" residents from the total residency population surveyed. However,
sex, ethnicity, foreigh medical graduation, and transfer from other
residency programs did not differentiate the two groups.
