Adverse Childhood Experiences and Substance Use: The Mediating Role of Executive Function Deficits.
Article in Journal of adolescence, 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
introductionWhile adverse childhood experiences (ACEs) are robust risk factors for adolescent substance use, the prospective neurocognitive pathways linking both cumulative and specific adversities to substance use remain understudied. This study tested a vulnerability model by examining whether executive function (EF) deficits mediate the link between cumulative and specific ACEs and substance use, and whether this pathway differs for deprivation- versus threat-based adversities.
methodsThis longitudinal study used parent- and youth-report data from the US Adolescent Brain Cognitive Development (ABCD) Study (N = 4731; M
resultsThe indirect effect of cumulative ACEs on substance use through EF deficits was significant, accounting for 10% of the total effect. Deprivation-based ACEs (material hardship and emotional neglect) were fully mediated by EF. Several threat-based adversities (e.g., household violence, bullying) also showed full mediation. In contrast, sexual abuse demonstrated a significant direct effect but no significant indirect effect through EF.
conclusionsEF deficits represent a significant pathway from cumulative ACEs to adolescent substance use, supporting a vulnerability model. This pathway appears robust for deprivation-based and many chaotic threat-based adversities, but sexual abuse is an exception that likely operates through non-EF, trauma-specific mechanisms. Prevention efforts should be multifaceted, incorporating EF-focused interventions for at-risk youth while prioritizing trauma-focused care for survivors of sexual abuse.
