1. Questionnaires were sent to physicians who were enrolled in the Navy's 3 months' intensive training courses in neuropsychiatry during World War II. Of the 221 "live" questionnaires sent to 36 states and the District of Columbia there were 189 returns, or 86%.2. The returns indicate that 103 (55%) of the group have continued to date in the practice of neuropsychiatry.3. About 85% of the group continuing in neuropsychiatry indicate almost exclusive attention to psychiatry while only about 5% state their time is given mostly to neurology.4. More than two-thirds of the present neuropsychiatric group report that the Navy training course influenced the nature of their present practice.5. Ninety percent of the present neuropsychiatric group stated that they found the training helpful in their present practice. All but one physician in fields other than psychiatry stated that the training was helpful in their present practice—over half of them, emphatically so.6. Prior experience or training in neuropsychiatry was indicated by 43% of the whole group, but detailed analysis of comments shows that such training was often quite limited. About two-thirds (69%) of the total group regarded the training as "basic orientation."7. Subsequent neuropsychiatric training, following demobilization, is reported by 89% of the continuing neuropsychiatric group, 35% of whom indicate Board certification.
