title: Accuracy of the clinical diagnosis of 'psychogenic disorders' in the presence of physical symptoms suggesting a general medical condition: a 5-year follow-up in 162 patients.
abstract: OBJECTIVE
  The range of unnoticed physical disorders in patients diagnosed with a psychogenic disorder varies widely. We investigated the accuracy of the clinical diagnosis of 'psychogenic disorder' where physical symptoms suggesting a somatic condition (PDPS) are present.
  
  
  METHODS
  All 162 cases of PDPS diagnosed between 01.01.1986 and 31.12.1987 in a medical clinic specializing in psychosomatic medicine were reviewed after 5 years. 148 follow-ups were complete. Initial diagnoses had been established using positive criteria for psychogenic diagnosis in a semistructured interview and a comprehensive clinical workup by trained clinicians.
  
  
  RESULTS
  In 2 (1.35%) foreign-language patients of 148 an orthopedic diagnosis had been missed. In 6 patients, the family physician gave formerly known findings a different interpretation. Half of these patients were foreigners; 5 were men; none improved; 5 had back pain.
  
  
  CONCLUSIONS
  A semistructured interview and positive criteria for psychogenic diagnosis permitted high diagnostic accuracy with an error of 1.35% in 148 cases.
