Do the various categories of somatoform disorders differ from each other in symptom profile and psychological correlates

Abstract

In routine clinical practice, the subcategories of various somatoform disorders are rarely used by the primary care physicians and there is lack of data to suggest any difference in the clinical manifestations of these subcategories. To compare the symptom profile, anxiety, depression, alexithymia, somato-sensory amplification and hypochondriasis of patients with persistent somatoform pain disorder with other subtypes of somatoform disorder. A total of 119 patients diagnosed with somatoform disorders according to the International Classification of Diseases-10th Revision (ICD-10) were evaluated for prevalence of somatic symptoms, anxiety, depression, alexithymia, hypochondriacal worry and somato-sensory amplification. No significant differences were found in the prevalence of various somatic complaints between those with persistent somatoform pain disorder group and those diagnosed with other somatoform disorders. Co-morbid anxiety and depression were seen in two-thirds of the patients, but again there was no difference in the prevalence of the same between the two groups. Similarly, no significant differences were found on alexithymia, hypochondriasis and somato-sensory amplification scales between the persistent somatoform pain disorder group and the group with other somatoform disorders. There are no significant differences between the various subcategories of somatoform disorders with regard to the prevalence of somatic symptoms, anxiety or depression and psychological correlates of alexithymia, hypochondriasis and somato-sensory amplification.
