Mental health trajectories of children and adolescents up to 5 years after the onset of the COVID-19 pandemic: a longitudinal study.
Article in Child and adolescent psychiatry and mental health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe COVID-19 pandemic had heterogeneous effects on the mental health of children and adolescents according to individual experiences, with some consequences persisting beyond the lifting of restrictions. We aimed to examine whether the perceived impact of the COVID-19 pandemic was associated with 2022-2025 trajectories of mental health difficulties in children and adolescents, and to identify associated risk and protective factors.
methodsData was drawn from the population-based SEROCoV-KIDS cohort study conducted in Geneva, Switzerland. The multidimensional perceived impact of the pandemic, as well as potential socio-demographic, health, family, social, and behavioral risk and protective factors were parent-reported at baseline, in 2022. Mental health difficulties were collected annually between 2022 and 2025. Generalized mixed effects models were used to estimate mental health trajectories by pandemic impact, and to assess risk and protective factors.
resultsOf 1907 children aged 2-17 years, 9.3% and 7.9% had experienced a negative and positive pandemic impact, respectively, while most of them were not or minimally affected (82.8%). Compared to their unaffected peers, negatively impacted children had more mental health difficulties in 2022 (incidence rate ratio [IRR]: 1.51; 95% confidence interval [CI] 1.34-1.70) and improving trends between 2022 and 2025 (IRR: 0.98; 95% CI 0.95-1.01). An average-to-poor financial situation was related to a milder mental health response to a negative impact in 2022 (IRR: 0.64; 95% CI 0.46-0.89). A positive pandemic impact tended to be associated with higher difficulties in 7-12 year old children in 2022 (IRR: 1.36; 95% CI 0.98-1.89), with stable trends over time.
conclusionAbout 5 years after the onset of COVID-19, the lasting mental health difficulties presented by children with a negative perceived impact of the pandemic had largely improved. Although globally reassuring, these findings call for proactive measures to prevent such long-term consequences on youth mental health in the event of future crises.
