Biopsychobehavioral correlates of insomnia. IV: Diagnosis based on DSM- III
TL Tan, JD Kales, A Kales, CR Soldatos and EO Bixler
DSM-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 five patients had a
principal diagnosis on axis III (physical 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. Ninety-five patients had multiple diagnoses. This study
confirms that patients with chronic insomnia have a high prevalence of
psychopathology and characteristic internalizing patterns of anxiety,
depression, obsessive-compulsiveness, phobia, and excessive somatic
concerns.
