According to the frustration-aggression hypothesis,social exclusion may be one of the reasons that lead to higher aggression and suicidal ideation of drug ab-stainers.In the present study,395 drug abstainers were investigated using questionnaires to explore the relationship between social exclusion,aggression and suicidal ideation and the mediating role of self-con-trol.The results showed that:(1)Social exclusion positively predicted the aggression and suicidal ideation of drug abstainers.(2)Self-control played a mediating role between social exclusion and aggres-sion and suicidal ideation.The findings of this study have practical implications,and future interventions may start from reducing social exclusion and enhanc-ing self-control to reduce the aggression and suicidal ideation of drug abstainers.
