Understanding Madmen: A DSM-IV Assessment of Adolf Hitler
Author(s): Frederick L. Coolidge, Felicia L. Davis, Daniel L. Segal
Abstract: Adolf Hitler's personality was investigated posthumously through the use of an informant version of the Coolidge Axis II Inventory (CATI), which is designed for the assessment of personality, clinical, and neuropsychological disorders. Five academic Hitler historians completed the CATI. The overall mean inter-rater correlation was moderately high for all 38 CATI scales' T scores (median r = .72). On Axis I, the highest mean T scores across raters were Posttraumatic Stress Disorder (76), Psychotic Thinking (73) and Schizophrenia (69). On Axis II, the highest mean T scores were Paranoid Personality Disorder (78), Antisocial Personality Disorder (78), Narcissistic Personality Disorder (77), and Sadistic Personality Disorder (76). Results of the present study support the reliability and preliminary validity of informant reports for psychological investigations of historical or contemporary figures.
