Background & Aims

Meta-analytic results show that individuals who engage in self-injury have lower pain sensitivity. However, these reviews have so far focused on adult populations. Self-injury typically begins in the early teen years and is most prevalent among youth and adolescents. To address this knowledge gap, we conducted a meta-analysis on pain sensitivity in individuals between aged 10-24 with self-injurious behavior.

Methods

MEDLINE (Ovid), Web of Science Core Collection (Clarivate) and PsycINFO (Ovid) were last searched on 9 February 2023. Titles, abstracts, and full texts of studies were independently screened by multiple observers. The Preferred Reporting Items for Systematic Reviews and Meta-analyses guideline was followed. Quality assessment was performed using the Newcastle-Ottawa scale.

Results

Of 4238 screened studies, 181 full-text articles were retrieved whereof 11 studies fulfilled the criteria (n=785).

Conclusions

Youth with self-injury show higher pain threshold (p = 0.006) and higher pain tolerance (p < .001) compared to healthy controls.
