To confirm a probable somatoform diagnosis the patient must have at least 5 of the 11 symptoms without demonstrable medical findings. Katon et al. 1990 focusing on the prognostic value of somatic symptoms used the SCL-90-R to provide an operational definition of high distressed high utilizers. The investigators observed linear increases in SCL-90-R dimension scores of Somatization Depression and Anxiety as they moved progressively through the somatic symptom groups from low to high. Kellner Hernandez and Pathak 1992 related distinct dimensions of the SCL-90-R to different aspects of hypochondriasis. The authors observed high levels of the SCL-90-R Somatization andAnxiety scores to be predictive of hypochondriacal fears and beliefs whereas elevations on Depression were not. Fear of disease correlated most highly with the SCL-90-R Anxiety score but the false conviction of having a disease was more highly correlated with somatization. Difficult Patients The Difficult Doctor-Patient Relationship Questionnaire DDPRQ Hahn Thompson Stern Budner Wills 1994 is a relatively new instrument that can reliably identify a group of patients whose care is experienced as often difficult by physicians. The construct validity of the instrument has been established by demonstrating strong associations between characteristics that have been associated with physician-experienced difficulty. The instrument classified 11-20 of primary care patients as difficult using a cutoff point that has been shown to distinguish between patients with difficult characteristics and those without. The DDPRQ score can also be used as a continuous measure. The instrument is available in two formats the DDPRQ-30 a 30-item version that requires 3-5 minutes to complete and a 10-item version the DDPRQ-10 requiring less than 1 minute. The DDPRQ is completed by the physician after meeting with the patient. Prior to the DDPRQ the study of the difficult .
