Abstract

Objectives
：This study was conducted to investigate differences in psychological characteristics between major depressive disorder (MDD) patients with and without suicide attempt using MMPI-2-RF.
Methods
：Subjects were 107 MDD patients who had visited the department of psychiatry of hallym university hospital and met the DSM-IV diagnostic criteria of MDD by the korean version of MINI-Plus 5.0.0. The patients were divided into suicidal attempters (n=43) and non-suicidal attempters (n=64) using C-SSRS. The one-way ANOVA was used to compare MMPI-2-RF scale scores between two groups. Additionally, ANCOVA was conducted considering the severity of depressive symptom and comorbidity as covariate.
Results
：Our results showed that Suicide/Death Ideation (SUI), Inefficacy (NFC) and Interpersonal Passivity (IPP) scales were significantly higher in the MDD patients with suicidal attempt compared to MDD patients without suicidal attempt (p<0.05). However, after controlling for the severity of depressive symptom and comorbidity, SUI scale showed a significant tendency (p<0.10).
Conclusions
：The result suggests that MMPI-2-RF scales could be a useful tool for identifying patients transitioning to actual suicidal attempts in the moderate or severe major depressive disorder group. Limitations of this study and directions for further research are also discussed.
