title: Three forms of somatization presenting in primary care settings in Spain.
abstract: The objective of this paper is to study the prevalence and clinical characteristics of functional, hypochondriacal, and presenting somatization (FSTS, HSTS, and PSTS, respectively) defined by standardized criteria, as well as the validity of their distinction in primary care in Spain. A two-stage epidemiological study of a representative sample (N = 1559) of primary care patients was carried out. In the first phase, the validated Spanish versions of General Health Questionnaire, Mini-Mental State Examination, and CAGE were used. In the second phase, the Standardized Polyvalent Psychiatric Interview, an interview for the multiaxial assessment of medical patients, was employed. The prevalence of any form of somatization in Spain was 21.3% (FSTS: 16.2%, PSTS: 9.4%, HSTS: 6.7%). Overlap of any of the three clinical forms was very frequent (42.7%). FSTS patients tended to be more chronic and showed higher scores in fatigue but lower scores in both depression and anxiety. Chronicity was frequent among somatizers, particularly in those who fulfilled more than one kind of somatization. Differences in diagnostic distribution among the three groups were also observed. In conclusion, this is the first study giving support to the validity of the distinction among three types of somatization in Spain, but overlap was more frequent than reported in North American studies.
