Abstract

Research suggests that adolescents' engagement in nonsuicidal self-injurious (NSSI) behaviors may be increasing over time, yet little is known regarding distal longitudinal factors that may promote engagement in these behaviors. Data from two longitudinal studies are presented to examine whether NSSI may be associated with peer influence processes. Study 1 included 377 adolescents from a community-based sample; Study 2 included 140 clinically-referred adolescents recruited from a psychiatric inpatient facility. In Study 1, adolescents' NSSI was examined at baseline and one year later. Adolescents' nominated best friend reported their own levels of NSSI. In Study 2, adolescents' NSSI was examined at baseline as well as 9 and 18-months post-baseline. Adolescents' perceptions of their friends' engagement in self-injurious behavior (including suicidality) and depressed mood also were examined at all three time points. Baseline depressive symptoms were measured in both studies; gender and age were examined as moderators of peer influence effects. Results from both studies supported longitudinal peer socialization effects of friends' self-injurious behavior on adolescents' own NSSI for girls, but not for boys, even after controlling for depressive symptoms as a predictor. Study 1 suggested socialization effects mostly for younger youth. Results from Study 2 also suggested longitudinal socialization effects, as well as peer selection effects; adolescents' NSSI was associated with increasing perceptions of their friends' engagement in depressive/self-injurious thoughts and behavior. Findings contribute to the nascent literature on longitudinal predictors of NSSI and to work on peer influence.

  • Emerging longitudinal evidence suggests that a friend's suicide is a meaningful predictor of an adolescent's own risk for future NSSI and suicidal behavior.

    “some emerging longitudinal evidence suggests that a friend’s suicide is a meaningful predictor of an adolescent’s own risk for future NSSI (Giletta et al. 2013, Prinstein et al. 2010, You et al. 2013) and suicidal behavior (e.g., Liu 2006)”

    From Adolescent Suicide as a Failure of Acute Stress-Response Systems. (2019) · cites this paper as Prinstein et al. 2010

    Study 2 Methods reports asking adolescents whether close friends had attempted suicide, not whether a friend had died by suicide. The General Discussion reports that friends’ self-harm predicted later NSSI among girls, but not boys. Thus the paper supports a narrower longitudinal peer-influence finding, not the claim that a friend’s suicide predicts NSSI; the citing sentence attributes the separate suicidal-behavior claim to Liu (2006).

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.
