The impact of trait impulsivity on suicidal behavior in adolescents with depression: the mediating and moderating role of depression severity, suicidal ideation intensity and age.
Article in BMC psychiatry, 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
objectiveThis study aims to investigate whether and how trait impulsivity differentiates suicidal ideation (SI) from suicide attempts (SA) in adolescents with Major Depressive Disorder (MDD), and the mechanisms through which impulsivity increases suicide attempt risk.
methodsA total of 185 adolescents diagnosed with MDD and suicidal ideation were categorized into SI (n = 118) and SA (n = 67) groups based on lifetime suicide attempt history. Study variables included impulsivity, depression severity, suicidal ideation intensity, and demographic and clinical characteristics. Group difference analysis compared variables between the two groups. Multiple logistic regression and moderated mediation models were applied to analyze the relationships between impulsivity and suicidal behavior.
resultsThe SA group exhibited younger age, higher depression severity, higher impulsivity, and higher suicidal ideation intensity compared to the SI group. Unadjusted logistic regression revealed that higher impulsivity was associated with higher odds of suicide attempt risk (OR = 1.03, p = 0.030); however, this association became nonsignificant after adjusting for covariates. Mediation analysis revealed a pattern consistent with an indirect association: trait impulsivity was statistically associated with higher suicide attempt risk via depression severity and suicidal ideation intensity, whereas its direct association was not significant. Age moderated the relationship between impulsivity and suicidal ideation intensity (B = -0.05, p = 0.039), showing stronger associations in younger adolescents.
conclusionTrait impulsivity alone does not directly differentiate suicidal ideation from suicide attempts. It is indirectly linked to suicidal behavior through the severity of depression and the intensity of suicidal ideation. The correlation between impulsivity and suicidal ideation intensity diminishes as age increases.
