Abstract
In this study, persistent effects of traumatic experiences on borderline personality trait were analyzed. Sequential data at three points in time were collected of 76 female students at a medical technology school. Examined were: 1) effects of past traumatic experiences on present borderline score of MCMI-II personality inventory, 2) temporal effects of recent situational stress experiences on the score, and 3) persistent effects of traumatic experiences, in contrast to the temporal effects. Results were as follows: 1) Students who reported a traumatie experience in infancy showed a significantly higher borderline score than those who did not. 2) Students who recently experienced a stressful life event showed a temporal increase in the borderline score. 3) Traumatie experiences had persistent effects, and situational stress had weak persistent effects on the score. Interaction effects of traumatie experience, situational stress, and time of data collection on borderline personality trait were also discussed.
