AbstractThis study was designed to evaluate psychological status of 150 individuals; 50 without chronic pain and without psychotherapeutic drug therapy, Group I or control group; 50 patients with chronic pain, Group II, chronic pain group with involvement of one region; and 50 chronic pain patients with involvement of two or more regions, Group III. All the participants were tested utilizing Millon Clinical Multiaxial Inventory -III (MCMI-III). Results were analyzed and compared for various clinical personality patterns including personality traits and personality disorders; severe personality pathology for schizotypal, borderline and paranoid personality pathology; and multiple clinical syndromes including generalized anxiety disorder, somatization disorder, major depression, bipolar manic disorder and dysthymic disorder, etc. There were no significant differences noted in clinical personality patterns or severe personality pathology. In the analysis of clinical syndromes, generalized anxiety disorder, somatization disorder, and depressive disorders were seen in a progressively greater proportion of patients in Groups I to III. In conclusion, this evaluation showed that abnormal clinical personality patterns are present in both groups of patients. Psychological abnormalities with generalized anxiety disorder, somatization disorder, and depression are commonly seen in chronic pain patients.
