Abstract
Somatic complaints are very common in general medical practice. They are not identified as psychic disorders and are treated symptomatically. We explore two kind of problems: 1. methodological problems such as the instruments to use to examine somatic complaints (it is evident that a checklist does not give the best results with suggestible patients); and 2. the relationships between somatic complaints and psychic disorders such as anxiety, depression and somatoform disorders. Psychiatric nosology is by no means clear and includes many diagnoses from “hysteria” to “hypochondria” or “psychosomatic”, “somatization”. In this study, we compare the symptoms collected by general practitioners, and their clinical diagnoses to those obtained by an automatic DSM-III diagnostic program. Adinfer was modified so that three DSM decision trees were systematically scanned: depressive, anxiety and somatoform disorders. This allows for an epidemiological study of somatic complaints and their relationship to depression and anxiety. The subjects' score on rating scales for anxiety and depression are compared with the diagnoses made by the expert system. We discuss the significance of somatic symptoms, the DSM classes and the value of expert systems in epidemiological studies.
