Background and Aims:
In the literature, a large amount of evidence of significant effects of emotions on pain perception. But depression does not develop in all patients with chronic pain. 
The article presents the results of the observation of 169 IDPs after arriving in Kharkiv region, including the victims, who were in direct combat zone, during period of  treatment in University hospital with different somatic diseases with pain. Control group -120 patients, residens of Kharkiv region. 
Methods:
Clinical interview, "Questionnaire symptoms of PTSD forced migrants", Impact of Event Scale Revised (IES-R), Zung Self-Rating Depression Scale (ZDS), HADS; The McGill Pain Questionnaire (MPQ) The West Haven-Yale Multidimensional Pain Inventory (WHYMPI), Pain Catastrophising Scale (PCS)
Results:
The results showed that 32.0 % of observed IDP’s have anxiety disorders (13.5 %), depressive disorders (10.3 %), PTSD (8.2 %). No significant correlation between anxiety disorders, depressive disorders, PTSD and frequency of acute pain, but strong  positive correlation present with chronic pain syndrome and  mental disorders at all (r=0,62, р≤0,01). Most significant correlation between catastrophising attitude of pain and chronicity of pain syndrome (r=0,82, р≤0,005), and frequency of catastrophising attitude of pain match more higher in IDP’s (р≤0,01).
Conclusions:
High risk of chronicity of pain syndrome in  IDP’s with different somatic diseases associated with mental disorders, us well anxiety disorders, depressive disorders and PTSD, and have positive correlation with catastrophising attitude of pain.
