The aim of this thesis was to study somatic symptoms profile in-patients with depressive and anxiety disorders. Two groups (30 patients in each diagnostic group) were investigated using somatic symptom subscale of SCL-90R (a self-report measure) and the Somatic Symptom Checklist of the CIDI (an interview method). The subjects also completed Toronto Alexithymia Scale TAS-20. The somatic symptoms profile of the depressive patients was characterized by pain, headache, and general weakness, while anxiety patients suffered more chest pain and autonomic symptoms. Patients with anxiety suffered slightly more frequent somatic symptoms than those with depression. There was a statistically significant positive correlation between total number of somatic symptoms (CIDI) and duration of illness in the whole sample, as well as in the depressive group. The same positive correlation was also found in the anxiety group.
