Abstract

Theoretical perspectives underscore that low pain tolerance may be a relevant 'barrier' to non-suicidal self-injury (NSSI). However, there is limited longitudinal work on the link between pain tolerance and NSSI, which is needed to assess if pain tolerance precedes NSSI engagement, and/or if NSSI precedes altered pain tolerance. Further, assessing both NSSI frequency and versatility (or number of NSSI methods), in addition to engagement, can provide a more nuanced understanding of the influence of pain on NSSI severity. In the present study, 1125 undergraduate students at a large university (72 % female, Mage = 17.96) reported on their NSSI frequency, NSSI versatility, and perceived pain tolerance. Four individual regressions were run to examine the potential bidirectional nature of the association between NSSI frequency and pain tolerance, and NSSI versatility and pain tolerance. Pain tolerance predicted both NSSI frequency and versatility over time. Neither NSSI frequency nor versatility predicted pain tolerance.

RESULTS suggest that high pain tolerance may be a risk factor for severe NSSI engagement.
