Stress, depression and left-sided psychogenic chest pain

Ninety men between the ages of 20 to 65 were studied to investigate the relationships between stress, depression and psychogenic pain. Three groups (the coronary heart disease (CHD) group; the left-sided psychogenic chest pain (LPCP) group; and the control group) comprising 30 patients per group, each completed the Social Readjustment Rating Scale (SRRS), as a measure of stress; the Schedule of Recent Experience, to document the recency of actual life events experienced as listed in the SRRS; and the Beck Depression Inventory, as a measure of the severity of depression. Separate analyses of the variables stress and depression failed to yield significant stress differences in the 3 groups, but the LPCP group was significantly more depressed than the CHD and control groups. Factor analysis, however, indicated that the stress profiles were significantly different in each of the 3 groups. This study indicates that the condition of LPCP shares a similar depressive profile to other psychogenic pain conditions and further lends support to the hypothesis linking psychogenic pain to depressive disorders.
