The aim of this study was to test the validity of a computer software program previously demonstrated to be capable of making DSM-IV neuropsychiatric diagnoses from the content analysis of speech or verbal texts. In this report, the computer program was applied to three personal writings of Napoleon Bonaparte when he was 12 to 16 years of age. The accuracy of the neuropsychiatric evaluations derived from the computerized content analysis of these writings of Napoleon was independently corroborated by two biographers who have described pertinent details concerning his life situations, moods, and other emotional reactions during this adolescent period of his life. The relevance of this type of computer technology to psychohistorical research and clinical psychiatry is suggested.
