Abstract
Objectives: This study was carried out to assess anger level and way of anger expression in patients with psychiatric disorders; Major depressive disorder, Bipolar disorder, Obsessive-Compulsive disorder, Paranoid Schizophrenia. And it was intended to identify relationship between anger-in symptoms and underlying depression.

Methods: MMPI-2(Minnesota Multiphasic Personality Inventory-2) and Rorschach test were completed by patients(MDD : 22, BD : 17, OCD : 14, SPR-P : 19). Correlation test was carried out to examine the relationship between MMPI-2 and Rorschach variables related to anger, depressive mood, somatization, hostility, aggression, impulsivity and interpersonal relationship, ego function. ANOVA, Scheffe test and ANCOVA which is exclusive depressive mood variable were conducted to compare character of anger expression between each diagnostic groups.

Results: Forty four percent of patients were classified as an anger-in type across four diagnostic groups. Each diagnostic group showed the differential expressive types of suppressed anger; somatization in MDD, externalizing impulsive behavior in BD, argument in OCD, persecutory thinking, impulsive and aggressive behaviors in SPR-P. After controlling depression, these differences disappeared except that impulsivity in SPR-P and BP. Especially high ego function patients is more trying to suppress and anger-in but these effort are failed, they tend to have more anger and anger-attack.

Conclusion: This study shows that patients with psychiatric disorders have high trait-anger but they tend to suppress or anger-in. And each group express another way their suppressed anger but their anger-in symptoms are more related to underlying depression than diagnosed type. Hence, these results suggest that first of all the intervention of depression is helpful to reduce anger-in symptoms for all diagnostic groups. And High ego function patients need more attention to their underlying depression, therapeutic approaches that they could express anger more appropriate.
