Abstract |
Nonsuicidal self-injury (NSSI; e.g., self-cutting without lethal intent) is a widespread mental health concern among emerging adults in university. Although accumulating evidence suggests that NSSI is primarily an emotion coping behaviour, little is known about variability in emotional response to pain among individuals who self-injure. Recent theory on NSSI suggests that individuals who engage in NSSI to self-punish may experience additional affective gains in response to pain compared to individuals without self-punishment motivations for NSSI and individuals who do not self-injure. To test this hypothesis, 82 undergraduate students (Mage = 21.52 years) were recruited from a mid-sized university, and reported on their emotions three times: at baseline, following a stress-induction task, and after a cold-pressor task. Although all participants showed decreased negative emotions (e.g., hostility, fear) and increased serenity following cold pain, students who engaged in NSSI specifically to self-punish also showed decreased guilt and sadness. The present findings demonstrate that pain may serve to regulate different emotions for students who self-injure depending on their motivations for engaging in NSSI. Additionally, findings suggest that prevention and intervention efforts aimed at reducing the need to self-punish may help to reduce some of the emotionally reinforcing properties of NSSI.
