[The relationship between depression, and interpersonal style, self-perception, and anger].

Purpose: The aim of this study was to investigate the relationship between depressive symptoms, and self-concept, interpersonal style, and anger in a group of patients diagnosed with depression and a control group that included volunteers without clinical symptoms.

Method: The study included 64 patients (patient group) diagnosed with depression according to DSM IV and 71 volunteers (comparison group) without a psychiatric diagnosis. The participants were given a questionnaire to collect data on their demographic characteristics and life circumstances, along with the Interpersonal Style Scale, Brief Symptom Inventory, Multidimensional Anger Scale, Social Comparison Scale, and Beck Depression Inventory.

Results: T-test comparisons showed that the patient group had significantly higher negative interpersonal style scores, higher anger, and more negative self-perception. The results of regression analysis showed that the severity of depression in the patient group could be predicted by aggressive and internalized anger, dissatisfaction with interpersonal relationships, and negative self-perception. The less severe depressive symptoms in the comparison group was predicted by lower level of education, dissatisfaction with life in general, and a positive self-perception.

Conclusion: Among both the patient and comparison groups, the depressive symptoms they experienced were closely related to how they perceived themselves, their life in general, and their interpersonal relationships. We therefore hypothesize that anger plays a significant role in the transformation of depressive symptoms into full-blown depression.
