Financial Toxicity, Quality of Life, and Psychological Resources in Breast Cancer Survivors : A Longitudinal Study

Starting soon

Conditions studied: Breast Cancer

In brief

Breast cancer survivors face significant financial stress (also called financial toxicity) due to the high costs of cancer treatment. This financial stress can worsen quality of life. Previous studies have demonstrated that breast cancer survivors may draw on inner psychological strengths to cope effectively. This study aims to examine whether psychological resources, specifically resilience and posttraumatic growth (PTG), buffer the longitudinal association between financial toxicity and quality of life (QoL) among breast cancer survivors. Hypotheses: H1: Financial toxicity is negatively associated with QoL over time. H2: Resilience moderates the association between financial toxicity and QoL, such that higher resilience attenuates the negative impact of financial toxicity. H3: Posttraumatic growth (PTG) moderates the association between financial toxicity and QoL, such that moderate to high levels of PTG attenuate the negative impact of financial toxicity. Participants will complete questionnaires at three time points: before their first chemotherapy cycle, at two months (mid-treatment), and at four months (end of chemotherapy). The questionnaires measure financial stress, quality of life, resilience, and posttraumatic growth. The study plans to enroll at least 160 participants. Data will be analyzed using statistical methods that track changes across time and test whether resilience and posttraumatic growth buffer the impact of financial stress on quality of life. All data will be de-identified and stored securely.
