Development and Comparability of Internalizing and Externalizing Symptom Spectra From Adolescence to Young Adulthood.
Article in International journal of methods in psychiatric research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesThis study examines the continuity and comparability of internalizing and externalizing symptom spectra from adolescence to young adulthood, addressing measurement challenges across developmental stages. Leveraging the Hierarchical Taxonomy of Psychopathology (HiTOP) framework, it explores whether symptom spectra in adolescence predict corresponding symptoms in young adulthood.
methodsData were drawn from JEPSY, a follow-up of the national KiGGS cohort (N = 2172, age 18-26). Adolescent internalizing and externalizing symptoms were assessed via the Strengths and Difficulties Questionnaire (SDQ) and substance use items. Adult outcomes included the Patient Health Questionnaire (PHQ-4), DSM-5 Cross-Cutting Symptom Measure (DSM-5 CC), and Personality Inventory for DSM-5 (PID-5). Factor analyses assessed structural consistency, and robust regression examined associations between adolescent and adult symptom spectra over 7-10 years.
resultsA four-factor model best captured the SDQ structure. In young adulthood, three spectra emerged: internalizing symptoms, externalizing traits, and substance use. Adolescent emotional and peer problems predicted internalizing symptoms in adulthood. Conduct problems and hyperactivity predicted externalizing traits. Substance use was associated with hyperactivity, smoking, and risky drinking-but negatively with peer problems.
conclusionThe findings support the continuity of broad psychopathological spectra and demonstrate that harmonized approaches can bridge measurement gaps and enhance longitudinal comparability.
