The relationship between childhood trauma, personality, and subjective well-being in early and late adolescence: a network analysis.
Article in Scientific reports, 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
Childhood trauma is strongly associated with impaired subjective well-being (SWB) in adolescence. However, the underlying mechanisms, particularly how they differ across specific developmental stages, remain inadequately explored. Based on the stress process model, childhood trauma may shape adolescent SWB by influencing the development of personal resources, such as personality traits and self-esteem. This study used network analysis to investigate the relationships among these factors based on the stress process model and compared the network model differences between early and late adolescents. A total of 2,620 adolescents aged 12–18 participated in the study. The results showed that neuroticism and self-esteem exhibited consistently strong connections with SWB across age groups within the network models. Emotional abuse and emotional neglect were consistently negatively connected to positive personal resources such as agreeableness, conscientiousness, extraversion, and self-esteem across all age groups, while emotional abuse was strongly positively connected to negative personal resources like neuroticism, which in turn were linked to adolescents’ SWB. Additionally, the associations between personality traits and SWB differed by developmental stage. Specifically, early adolescents exhibited a stronger connection between extraversion and SWB, while late adolescents showed a stronger connection between agreeableness and SWB. Early adolescents also displayed a weaker connection between openness and self-esteem compared to late adolescents, indicating that differences in the relationships among personality traits across developmental stages may be important factors influencing SWB. This study provides valuable insights into the developmental stage-specific mechanisms linking childhood trauma, personality traits, and subjective well-being, offering a foundation for age-tailored interventions to enhance adolescent mental health.
