Lifetime Prevalence of Nonsuicidal Self-Injury in Adolescents: Reliability of a Dichotomous Survey Item.
Article in International journal of methods in psychiatric research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
introductionNonsuicidal self-injury (NSSI) is a widespread phenomenon among adolescents. Accurate estimates of prevalence rates when screening for NSSI are essential both in research and clinical settings. However, high variability raises the question of the reliability of self-reported NSSI prevalence.
methodsThe reliability of a dichotomous survey item on history of NSSI was investigated longitudinally using data from five time points across 16 months in a community sample (N = 253) of Swedish adolescents (age M = 14.21 years, SD = 0.56, 58.5% female).
resultsAbout one in five participants (18.97%) changed their answer compared to their initial response. Of those who answered negatively on lifetime prevalence of NSSI at baseline, 8.95% later acknowledged NSSI, while 57.69% of those initially acknowledging NSSI later answered negatively. Fleiss' kappa across all five measurements indicated moderate agreement. Cohen's kappa between baseline and 12 months indicated moderate agreement.
conclusionsIn this adolescent sample, the reliability of a single-item question on NSSI history was moderate. More than half of those who initially acknowledged a history of NSSI answered negatively at a later time point. Interpretation of self-reported lifetime prevalence rates of NSSI in adolescents using dichotomous survey items needs to be made cautiously.
