Abstract

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: 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.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
