Influence of financial toxicity on posttraumatic growth in primary caregivers of cancer patients undergoing chemotherapy: the chain mediating effect of benefit finding and self-disclosure.

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
backgroundPrimary caregivers of cancer patients undergoing chemotherapy frequently experience posttraumatic growth. While financial toxicity has been linked to this phenomenon, the pathways through which it exerts its effects remain poorly understood.
methodsUsing a cross-sectional design, 242 primary caregivers of cancer patients undergoing chemotherapy were recruited through convenience sampling between September 2025 and December 2025 at a tertiary hospital in Qingdao, China. Data were collected using a custom-designed Sociodemographic Information Questionnaire, the Comprehensive Score for Financial Toxicity (COST), the Benefit Finding Scale (BFS), the Distress Disclosure Index (DDI), and the Posttraumatic Growth Questionnaire (PTG). Chain mediation analysis was performed using PROCESS v3.3 Model 6 for SPSS.
resultsFinancial toxicity showed a significant negative direct effect on posttraumatic growth within the mediation model (Bootstrap 95% CI: − 0.228, − 0.036). In addition, higher levels of financial toxicity were associated with lower benefit finding (Bootstrap 95% CI: − 0.262, − 0.113) and reduced self-disclosure (Bootstrap 95% CI: − 0.113, − 0.012). Benefit finding and self-disclosure together served as significant mediators in the relationship between financial toxicity and posttraumatic growth (Bootstrap 95% CI: − 0.071, − 0.022).
conclusionsFinancial toxicity influences posttraumatic growth through both direct and indirect pathways, with benefit finding and self-disclosure acting as key mediators. Notably, benefit finding appears to weaken the mediating role of self-disclosure. Clinical strategies aimed at enhancing benefit finding and promoting self-disclosure may help promote posttraumatic growth and improve quality of life among primary caregivers of cancer patients undergoing chemotherapy.
