Objectives : This study was designed to investigate the correlation between defense mechanism and posttraumatic stress disorder in burn patients. Methods : We recruit 40 burn patients and we evaluate sociodemographic characteristics, characteristics related to burn, korean version of Impact of Event Scale-Revised (IES-R), Korean Version of Center for epidemiologic studies depression scale (CES-D) and Ewha Defense Mechanisms Test (EDMT). Multiple regression analysis was performed to evaluate the correlation between EDMT score and IES-R score. Results : Factor 2 of EDMT which consists of Ego-expansion subjects was significantly correlate with IER-S score. In factor 2, Controlling (β=-0.299, p<0.05), Sublimation (β=-0.276, p<0.05) is significantly correlate with IER-S score. Conclusions : Some subjects of defense mechanism was significantly correlate with IES-R score. it might be helpful to understand defense mechanism for the posttraumatic stress disorder in burn patients.

Objective: The purpose of this study was to investigate characteristics of the defense mechanism of oriental medicine students by using Ewha Defense Mechanism Test(EDMT) preliminarily. Method: We described the characteristics of the defense mechanism of oriental medicine students and compared the scores of EDMT with standard group. We analysed the differences of defense mechanism by sex (male, female) and age($\leq$29 and $\geq$30 yrs old) within oriental medicine students. The score of EDMT were verified by examination of one sample t-test and unpaired t-test. Results and Conclusions: First, there was no Major Defense Mechanism in oriental medicine students. Second, oriental medicine students had more defensive, passive inclination and used Evasion and Show-off more frequently. Third, the differences within oriental medicine students depended on age rather than sex. The younger students used immature and neurotic defense mechanisms more frequently, and the older students had more defensive and passive inclination.

Objectives : This study explored the differences in their ego defense mechanisms between adolescents with conduct disorder and normal adolescents. Methods : Subjects were 35 adolescents with conduct disorder and 44 normal adolescents. The Ewha Defense Mechanism Test (EDMT), consisting of 200 items and 20 scales, was administered, to examine the defense mechanisms of both groups of adolescents. Results : Normal adolescents presented statistically significantly higher scores on the reaction formation, controlling, suppression, anticipation, dissociation, and distortion scales than did adolescents with conduct disorder. Zn addition, adolescents with conduct disorder used neurotic defense mechanisms of both neurotic and mature levels less frequently than normal adolescents did. Factor analysis revealed that, normal adolescents had higher scores on ego-expansive factor scales and behavior control factor scales thanadolescents with conduct disorder did. Conclusion : The results suggest adolescents with conduct disorder use mature and ego-expansive defense mechanisms less frequently than do normal adolescents.

This study was carried out to know the main defense mechanisms used by adolescent victims of school violence. Subjects of this study are composed of 41 adolescent victims(clinical group) and 40 normal adolescents(control group). Clinical group is divided into four subgroups of inpatient, outpatient, day hospital, and school groups. Used scales are Ewha Defense Mechanisms Test(EDMT) and Staittrait anger scale. Several important results are found. Adoescent victims use neurotic defense mechanisms of neurotic and mature level less frequently than normal adolescents. In clinical group day hospital adolescents use more mature defense mechanisms than outpatient adolescents. Displacement and acting out are correlated with trait and sate anger. Somatization is correlated with trait anger, and regression is correlated with state anger significantly.
