The effect of stressful life events on adolescents with depression: the chain mediating role of basic psychological needs and self-esteem.
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
purposeAdolescent depression has emerged as a critical global public health concern, with stressful life events identified as key environmental risk factors. However, the underlying psychological mechanisms in clinically diagnosed adolescents remain insufficiently explored. This study aims to examine whether basic psychological needs and self-esteem serve as sequential mediators in the relationship between stressful life events and depressive symptoms. PATIENTS AND
methodsA total of 312 adolescents (aged 12–19 years; 68.8% female) diagnosed with depressive disorder were recruited from a psychiatric hospital in Northwest China. Participants completed validated self-report measures including the Adolescent Self-Rating Life Events Checklist (ASLEC), the Basic Psychological Needs Scale (BPNS), the Rosenberg Self-Esteem Scale (SES), and the Self-Rating Depression Scale (SDS). A serial mediation model was tested using SPSS PROCESS (Model 6), controlling for gender.
resultsStressful life events positively correlated with adolescent depressive symptoms (B=0.305, p<0.001). In the chain mediation model, basic psychological needs and self-esteem acted as sequential mediators, explaining 47.25% of total variance (indirect B=0.144, 95% CI [0.088, 0.202]). Decomposition showed basic needs alone mediated 20.62% (B=0.063, CI[0.027,0.107]), self-esteem 19.57% (B=0.060, CI[0.027,0.096]), and the chain pathway (needs→self-esteem) 7.05% (B=0.022, CI[0.009,0.038]).
conclusionFindings support a theoretically grounded chain mediation model in which stressful life events are associated with lower levels of adolescents’ basic psychological needs satisfaction, which in turn relates to reduced self-esteem and more severe depressive symptoms. These results integrate Self-Determination Theory and Maslow’s hierarchy of needs, offering evidence-based insight into the process through which environmental stress is associated with. Clinically, this suggests that interventions targeting need satisfaction and self-esteem restoration may may be associated with reduced depression in adolescent patients.
