Network analysis of childhood trauma and meaning in life in adolescents with and without depression.
Article in BMC psychology, 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
backgroundAdolescent depression represents a global mental health crisis with dramatically increasing rates worldwide. Childhood trauma (CT) is an established risk factor that disrupts meaning in life (MIL), a process that may exact in a complex interaction with depression. Yet, the trauma-meaning interactions in depressed adolescents remain poorly understood, which impedes development of targeted interventions for vulnerable youth.
methodsIn this study, we applied network analysis in a large sample of 2,523 Chinese adolescents (Mage = 14.3 years, 46% male) to examine how CT and MIL interrelate in adolescents, and whether these relationships differ by depression status. Based on Children’s Depression Inventory scores (cutoff = 20), 859 adolescents were classified as depressed and 1,664 as non-depressed. Partial-correlation networks were estimated for four CT subtypes (physical abuse, physical neglect, emotional abuse, and emotional neglect) and two MIL dimensions (presence of meaning and search for meaning).
resultsDepressed adolescents exhibited significantly stronger global connectivity between trauma and meaning constructs, indicating maladaptive coupling when depression is present. Six network edges differed between groups, with “Physical Abuse-Search for Meaning” and “Emotional Neglect-Search for Meaning” bridging CT and MIL and stronger in depressed adolescents.
conclusionsThese findings suggest that CT shows a broader association with meaning-making processes in depression. Physical abuse and emotional neglect are particularly associated with adolescents’ capacity to search for and construct meaning. Results underscore the critical need for comprehensive trauma screening in adolescent depression assessments and highlight meaning-centered interventions as promising therapeutic approaches for prevention and treatment of depression in trauma-exposed youth.
