Perceived stress and post-traumatic growth in breast cancer patients: a moderated mediation model.
Article in BMC psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeWhile the negative correlation between perceived stress and post-traumatic growth (PTG) in breast cancer patients is well-documented, the underlying mechanisms remain unclear. This study explores a moderated mediation model to investigate whether anxiety mediates this relationship and whether benefit finding (BF) moderates the mediation process.
methodsA total of 1,135 breast cancer patients completed questionnaires assessing PTG, perceived stress, BF, and anxiety. The General Situation Table, The Simplified Chinese Version of the PTG Inventory (C-PTGI), The Chinese Version of the Perceived Stress Scale (CPSS), The Benefits Finding Scale (BFS), and The Hospital Anxiety and Depression Scale (HADS) for breast cancer patients were included in this study. Descriptive statistics, t-tests, one-way analysis of variance, and Pearson’s correlation analyses were used. The effect of moderated mediation was tested by the PROCESS macro (Models 4 and 14) for SPSS 27.0 by Hayes using 5000 bootstrap samples.
resultsA total of 1,135 valid questionnaires were collected (effective response rate: 94.58%). The mean scores for perceived stress, PTG, anxiety, and BF were 37.84 ± 6.799, 46.37 ± 19.910, 8.24 ± 4.135, and 52.15 ± 14.041, respectively. Pearson’s correlation analysis showed that anxiety and perceived stress were negatively correlated with both PTG and benefit-finding, while BF was positively correlated with PTG. Mediation analysis revealed that perceived stress not only predicts PTG directly but also indirectly through the mediating effect of anxiety. The results of the moderated mediation model test indicated that BF moderated the mediation effect, particularly in patients with low to moderate levels of BF, where the conditional indirect effect was significant.
conclusionThis study clarifies the dual role of anxiety and BF in the stress-post-traumatic growth relationship among breast cancer patients. In clinical practice, healthcare teams can use mindfulness-based therapy to help patients relieve stress, while conducting targeted interventions on patients’ BF levels through cognitive behavioral therapy. By adjusting patients’ cognitive patterns and behavioral habits, they can guide patients to actively identify positive aspects throughout the disease course, ultimately facilitating the improvement of their post-traumatic growth levels.
