Childhood predictors of avoidant personality disorder traits in adolescence: a seven-wave birth cohort study.
Article in Journal of child psychology and psychiatry, and allied disciplines, 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
backgroundAlthough it is widely assumed that avoidant personality disorder (AvPD) originates in childhood, there is little prospective research to substantiate this claim. We therefore aimed to determine whether presumed childhood risk factors predict AvPD traits at 16 years.
methodsA population-based sample (n = 1,077; 50.9% female) from the 2003 and 2004 birth cohorts in Trondheim, Norway was examined biennially from 4 to 16 years. The number of AvPD traits at the age of 16 was assessed with the structured clinical interview for DSM-5 personality disorders and regressed on the intercept and growth in child risk and protective factors until the age of 14.
resultsThe prevalence of AvPD at the age of 16 was 3.2% (95% CI: 2.2-4.1). Higher levels and an increased number of social anxiety symptoms over time, as well as increased negative affectivity/neuroticism, predicted a higher number of AvPD traits. When the levels and changes in these factors were adjusted for, less and decreasing extraversion forecasted more AvPD traits, as did declining self-worth, higher levels of parental AvPD traits, and increased onlooking behavior.
conclusionsNeuroticism, low extraversion, social anxiety symptoms, passive onlooking behavior, and low self-worth predicted a higher number of AvPD traits in adolescence, as did more AvPD traits in parents. Efforts to enhance self-worth, reduce social anxiety, and promote peer interaction among onlooking children may reduce the development of AvPD traits in adolescence.
