Abstract
DSM-III [Diagnostic and Statistical Manual of Mental Disorders III] diagnoses were established for 100 patients with chronic insomnia. Principal and additional diagnoses on axis I and II (psychiatric and personality disorders) were extremely prevalent. Only 5 patients had a principal diagnosis on axis III (phsical disorders). The most common diagnoses on axis I were dysthymic, anxiety, somatoform and substance use disorders. Compulsive personality disorder or trait was the most common axis II diagnosis. Of the patients, 95 had multiple diagnoses. Apparently, patients with chronic insomnia have a high prevalence of psychopathology and characteristic internalizing patterns of anxiety, depression, obsessive-compulsiveness, phobia and excessive somatic concerns.
