Grade-specific associations between insomnia and depressive symptoms in adolescents: a cross-lagged panel network analysis.
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. 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
backgroundInsomnia and depression frequently co-occur during adolescence, posing significant challenges to adolescent mental health. However, the direction of their association remains inconsistent in the literature and may show grade-specific patterns. Grounded in psychopathology network theory and informed by the developmental psychopathology perspective, this study examined symptom-level associations between insomnia and depression to better characterize these association patterns.
methodsThis study employed cross-lagged panel network analysis to explore symptom-level interactions between insomnia and depression from Grades 5 to 12, capturing both contemporaneous (within-timepoint) associations and temporal (cross-timepoint) predictive associations. A large cohort of 175,950 adolescents (M
resultsThe findings showed both relatively stable and grade-specific patterns of association between insomnia and depression. In the contemporaneous networks, Motor descriptively showed the highest strength centrality in most grades, although the symptom with the highest centrality differed in some grades. In the temporal networks, descriptive centrality results indicated that Sad Mood had the highest out-expected influence in most grades, except for Anhedonia in Grade 6 and 8 and Suicide in Grade 12; Daily Function descriptively had the highest in-expected influence in most grades, except for Fatigue in Grade 10 and 11.
conclusionThese findings highlight several symptoms in the insomnia-depression network, with some variation across grades. By moving beyond total-score approaches, this symptom-level perspective provides exploratory insights that may shed light on inconsistencies in prior findings regarding the directionality of the insomnia-depression association and offer a more nuanced understanding of insomnia-depression relationships during adolescence.
