Abstract

Background While prior research has demonstrated that peer victimization and bully perpetration contribute to non-suicidal self-injury (NSSI) and suicidal thoughts and behaviors (STBs), it remains unclear whether these interpersonal processes differentiate self-injuring adolescent suicide ideators and attempters.Methods The study included adolescents aged 13-18 years (n = 223; M = 15.31, SD = 1.34) recruited from an acute inpatient program. Participants were divided into two groups: (1) NSSI SI (n = 106): endorsed past year NSSI, current suicide ideation, and no lifetime suicide attempts and (2) NSSI SI+SA (n = 117): endorsed past year NSSI, current suicide ideation, and lifetime suicide attempts. Adolescents completed clinical interviews (i.e., mental disorders, NSSI, and STBs) and self-report measures assessing peer victimization, bully perpetration, and depression severity.Results NSSI SI+SA youth reported higher levels of peer victimization and bully perpetration than NSSI SI youth (ps < 0.01, ds = 0.36-0.37). Among the NSSI SI+SA youth, bully perpetration was associated with a greater number of past month suicide attempts (p = 0.02, RR = 1.07). Only peer victimization was associated with greater NSSI behaviors in the past month (p = 0.04, RR = 1.01).Limitations The study is cross-sectional, and reports of peer victimization and bully perpetration rely on self-report assessment.Conclusions Peer victimization and bully perpetration differentiated adolescent suicide ideators and attempters, highlighting the need to address bully perpetration in addition to peer victimization in suicide interventions and research.

  • When environmental exposures, especially acute stress, combine with neural diatheses, the likelihood of suicidal and non-suicidal behaviors may increase.

    “Coupled with specific environmental exposures—particularly acute stress (e.g., peer victimization, interpersonal loss)—the likelihood of suicidal (21–23) and non-suicidal (24–26) behaviors may increase.”

    From Neural correlates associated with suicide and nonsuicidal self-injury in youth (2021) · cites this paper as [24]

  • Adolescent interpersonal stress may initially compromise cortical regions involved in cognitive flexibility and future-oriented thinking, which over time may potentiate suicidal and non-suicidal thinking.

    “Additionally, adolescent interpersonal stress (e.g., loss (21, 25), peer victimization (22, 24))—may initially act on cortical regions by compromising cognitive flexibility and future oriented thinking (124), which over time, may potentiate suicidal and non-suicidal thinking (125, 126).”

    From Neural correlates associated with suicide and nonsuicidal self-injury in youth (2021) · cites this paper as [24]

  • The SITBI and BSSI criteria have been used to classify suicidal thoughts and behaviors groups in several prior studies.

    “The SITBI and BSSI criteria have been used to classify STB groups in several prior studies (e.g., Stewart et al. 2017b; Stewart et al. 2017c; Vergara et al. 2019).”

    From Life stress and suicide in adolescents (2019) · cites this paper as Vergara et al. 2019

  • The sample consisted of adolescents from an intensive residential program who had severe psychiatric symptoms, difficult peer, family, and/or academic circumstances, and very high rates of suicidal thoughts and behaviors.

    “Last, adolescents in the present sample were recruited from an intensive residential treatment program. They had severe psychiatric symptoms, complex and often unsupportive peer, family, and/or academic environments, and very high rates of STBs (see also Stewart et al. 2017b, c; Vergara et al. 2019).”

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.
