摘要:Aim: The high degree of group commit suicide phenomenon had been a social concern. The purpose of this paper was to try to understand how emotion regulation affected suicide attitude in graduate students. Method: 406 postgraduates in three universities of Chongqing were tested with Emotion Regulation Questionnaire (ERQ) and Suicide Attitude Questionnaire (QSA). Results: On the emotion regulation side, there were significant gender differences in revealing, and significant grade differences in rumination. When encountered with negative emotion, avoidance and suppression happened much more frequently than rumination and revealing. The latter two happened more frequently when postgraduates encountered positive emotions. On the suicidal attitude side, there were significant grade and professional differences in attitudes towards the suicide victims’ families and significant grade differences in euthanasia attitudes. Correlation analysis and regression analysis showed that suppressing negative emotion and avoiding positive emotion were important variables to affect graduate suicide attitude. Conclusion: Inappropriate emotional regulation might be an important reason for the postgraduates who approved of suicide.
