1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectiveAlthough empirical evidence of NSSI contagion within adolescent friendships has been documented, the specific mechanisms remain poorly understood. The current study employed a longitudinal design to investigate the influence of NSSI in adolescents' peer groups on their own NSSI behaviors. Additionally, the study examined the mediating role of self-esteem and the specific conditions under which NSSI contagion occurs.

methodThe study involved 326 adolescents (mean age = 13.5, 59.2% female) nested within 163 friendship dyads. NSSI behavior, self-esteem, self-compassion, alexithymia, and personal distress were assessed at baseline (T1), and NSSI behavior was assessed again after three months (T2). A cross-lagged Actor-Partner Interdependence Model (APIM) was used to estimate the NSSI contagion model. In this model, self-esteem served as a mediator in the contagion of NSSI behaviors, while alexithymia, self-compassion, and personal distress acted as moderating factors of this mediating effect.

resultsThis study revealed that friends' NSSI status at baseline significantly predicted adolescents' own NSSI status after three months. Self-esteem was found to mediate the NSSI contagion effect exclusively in situations where adolescents exhibited high alexithymia, low self-compassion, and high personal distress.

conclusionsThis research highlights the role of adolescent friendships in NSSI contagion and elucidates the potential mediating role of self-esteem in this contagion. These findings may provide substantial implications for the prevention of the NSSI contagion among adolescents.
