Abstract

Background In this daily dairy study of adolescents at elevated suicide risk, we examined proximal associations between nonsuicidal self-injury (NSSI) and suicidal thoughts as well as behaviors. We also investigated the prominence of the anti-suicide function underlying NSSI engagement, relative to intrapersonal and interpersonal motives.Methods Seventy-eight adolescents (67.9% female; ages 13-17) hospitalized due to suicide risk completed daily surveys assessing NSSI and suicidal thoughts for four weeks after discharge (n=1621 observations). Suicidal behavior (actual, aborted, interrupted suicide attempts) was assessed at 1-month follow-up.Results Over and above lifetime NSSI, adolescents who generally experienced more enduring (OR=2.54, p=<.001) and intense (OR=1.87, p=.002) suicidal ideation were more likely to engage in NSSI on a given day. Moreover, NSSI likelihood increased when adolescents experienced more enduring (OR=1.99, p<.001) and intense (OR=1.66, p<.001) ideation relative to their typical levels. This pattern was consistent for those with recent NSSI. The anti-suicide function of NSSI was frequently endorsed at hospitalization and when NSSI occurred daily (65.6% of the time), alongside the intrapersonal-negative motive (to avoid aversive states). Exploratory analyses suggest adolescents with suicidal behavior within the month after discharge experienced higher NSSI levels reported daily over the same period (Hedge's g=1.26, p=<.001).Limitations Daily-level associations were examined concurrently and generalizability of results is limited by sample characteristics.Conclusions The notable proximal associations between NSSI and suicidal thoughts and behaviors, as well as the prominence of the anti-suicide function, point to the importance of intervention efforts targeting these intersecting phenomena among adolescents at elevated suicide risk.

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.
