“…There are two possible explanations. Like Boyne and Hamza (2022) suggested, pain habituation might be more relevant to NSSI onset v. maintenance. Since our sample was injuring themselves for more than 2 years already, continued NSSI might not reduce pain tolerance anymore, but NSSI at onset might have reduced pain tolerance.…”

“…However, a recent longitudinal study with young adults engaging in NSSI showed that higher pain threshold and tolerance at BL predicted higher NSSI versatility, i.e. number of different NSSI methods, in the past year at 1 year FU (Boyne & Hamza, 2022). Higher pain threshold at BL also predicted higher NSSI frequency in the past year, even though this result was not significant anymore after Bonferroni correction.…”

“…It is likely that a considerable number of participants would have tolerated a higher temperature than 50 °C since the distribution of pain tolerance is left-skewed. Another limitation is that we only assessed NSSI frequency, but not other indicators of NSSI severity, like NSSI versatility, which has been associated with PS (Boyne & Hamza, 2022). Taking into account both NSSI frequency and versatility might yield important insight in the future (Ammerman, Jacobucci, Turner, Dixon-Gordon, & McCloskey, 2020).…”

Background The pain analgesia hypothesis suggests that reduced pain sensitivity (PS) is a specific risk factor for the engagement in non-suicidal self-injury (NSSI). Consistent with this, several studies found reduced PS in adults as well as adolescents with NSSI. Cross-sectional studies in adults with borderline personality disorder (BPD) suggest that PS may (partially) normalize after remission or reduction of BPD symptoms. The objective of the present study was to investigate the development of PS over 1 year in a sample of adolescents with NSSI and to investigate whether PS at baseline predicts longitudinal change in NSSI. Methods N = 66 adolescents who underwent specialized treatment for NSSI disorder participated in baseline and 1-year follow-up assessments, including heat pain stimulation for the measurement of pain threshold and tolerance. Associations between PS and NSSI as well as BPD and depressive symptoms were examined using negative binomial, logistic, and linear regression analyses. Results We found that a decrease in pain threshold over time was associated with reduced NSSI (incident rate ratio = 2.04, p = 0.047) and that higher pain tolerance at baseline predicted lower probability for NSSI (odds ratio = 0.42, p = 0.016) 1 year later. However, the latter effect did not survive Holm correction (p = 0.059). No associations between PS and BPD or depressive symptoms were observed. Conclusion Our findings suggest that pain threshold might normalize with a decrease in NSSI frequency and could thus serve as a state marker for NSSI.
