Substance use and mental health outcomes in children and adolescents exposed to household dysfunction: mediating role of emotional intelligence.
Article in BJPsych open, 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
backgroundHousehold dysfunction represents one of the most prevalent adverse childhood experiences worldwide, and has been previously associated with an increased risk for mental health problems. However, little is known about the protective role of emotional intelligence in this association.
aimsTo explore whether emotional intelligence mediates the relationship between household dysfunction and (a) substance use (age at first use and severity index) and (b) psychopathological status (behavioural/emotional problems, global functioning and number of lifetime psychiatric diagnoses and pharmacological treatments).
methodA simple mediation model was employed. A total of 187 children and adolescents aged 7-17 years, from the multicentre EPI-Young-Stress Project, were included in the study. Household dysfunction was assessed following the validated Tool for Assessing the Severity of Situations in which Children are Vulnerable (TASSCV) criteria and emotional intelligence was evaluated with the Trait Emotional Intelligence Questionnaire for Children Short Form (TEIQue-CSF) parent version.
resultsThere is an indirect-only mediation effect of emotional intelligence on the relationship between household dysfunction and children's and adolescents' age at first substance use (proportion mediated: 31.40%, 99% CI -0.53 to -0.02) and severity index (proportion mediated: 23.69%, 99% CI 0.50-0.34), as well as the number of lifetime psychiatric diagnoses (proportion mediated: 45.38%, 99% CI 0.19-0.60) and psychiatric drugs prescribed (proportion mediated: 48.75%, 99% CI 0.19-0.57). A complementary mediation effect of emotional intelligence was found between household dysfunction and emotional/behavioural problems (proportion mediated: 56.37%, 99% CI 0.32-0.80), as well as global functioning (proportion mediated: 54.20%, 99% CI -0.72 to -0.28).
conclusionsEmotional intelligence emerges as a putative protective factor against the negative consequences of household dysfunction on mental health and substance use. Emotional intelligence should be considered a primary target in preventing and promoting the health of youth exposed to household dysfunction.
