Introduction
This systematic review and meta-analysis aimed to (i) examine the associations between experiential avoidance (EA), non-suicidal self-injury (NSSI), and suicide experiences, and (ii) identify sample- and methodological-related variables affecting the strength of these associations.

Method
Medline, Embase, PsychINFO, Web of Science, and CINAHL were searched until April 2020. Random-effect meta-analyses were applied. The I2 statistic and the Egger's test assessed heterogeneity and publication bias. Meta-regression analyses were used to evaluate the impact of moderator variables on the strength of these associations.

Results
Data from 19 independent studies based on n = 9900 participants were pooled. The analyses demonstrated a weak but significant association between EA and NSSI. None of the examined moderator variables influenced the strength of this relationship. There was an indication of publication bias, suggesting that this association may have been inflated. The associations between EA, and suicide ideation and behaviors were moderate to strong.

Discussion
The current study concluded that (i) the EA model for NSSI should be revised by incorporating new evidence implicating feelings of relief in NSSI, and (ii) future studies should examine interactive factors between EA and key psychological components in the pathways to suicide experiences because these findings have direct clinical implications.
