Suicidal ideation with and without intention to act: A transdiagnostic network analysis on the interplay between psychopathology, impulsivity, and childhood maltreatment.
Article in Psychological medicine, 2025. 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
backgroundSuicide represents a significant public health concern. Suicide prevention strategies are shifting toward transdiagnostic perspectives examining interrelated risk factors, but their interrelationships remain unclear. This study investigated relationships between psychopathological dimensions, impulsivity, and childhood maltreatment in individuals with suicidal ideation (SI), comparing those with versus without intention to act using network analysis.
methodsData were obtained from the Suicide Prevention and Intervention Study project. Participants were categorized into two groups based on their intention to act according to the Columbia Suicide Severity Rating Scale. Psychological symptoms, impulsivity traits, and childhood maltreatment were assessed. Network analysis was performed, and centrality measures were computed.
resultsA total of 1,265 individuals were categorized into the SI without intention to act (
conclusionsThis study identifies symptom interaction patterns between individuals with SI without and with intention to act. Understanding these relationships may improve suicide risk assessment and inform personalized interventions, potentially reducing the transition from ideation to action. Trauma-focused approaches addressing emotional abuse may be especially relevant for individuals at high risk.
