Abstract Based on the integrated theoretical model of non-suicidal self-injury (NSSI), a total of 675 college students were surveyed to explore the effect of childhood trauma on NSSI, the mediating effect of expression suppression and the moderating effect of reward sensitivity. Results showed that childhood trauma could not only predict NSSI directly, but also indirect positively predict NSSI via expression suppression. Different components of reward sensitivity played moderating roles in the mediation model, reward response impaired the direct positive effect of childhood trauma on NSSI and the positive effect of expression suppression on NSS, reward pleasure seeking strengthened the positive effect of expression suppression on NSSI.
