"Application for voluntary hospitalization" form: possible aid to diagnosis of mania.

"Application for Voluntary Hospitalization" signed by 13 manics (33 forms) and 13 paranoid schizophrenics (37 forms) at the time of their admissions were examined to test the validity of the hypothesis that one who writes anything more than his first name, middle name, or initial, and last name is likely to be manic. A physician and a nurse who were blind to the diagnosis were able to differentiate, at a significant level, mania from paranoid schizophrenia, using this criterion.
