Factors associated with health literacy among caregivers of patients with advanced cancer: a cross-sectional path analysis using structural equation modelling
This cross-sectional study of 280 family caregivers in China reveals that higher self-efficacy and lower caregiver burden are significantly associated with better health literacy among those caring for patients with advanced cancer, while health anxiety showed no significant link.

When a loved one is diagnosed with advanced cancer, the family often becomes the primary support system, taking on a role that goes far beyond simple companionship. These family members must learn to navigate complex medical instructions, monitor subtle changes in symptoms, manage medications, and communicate effectively with doctors, all while coping with their own emotional strain. This ability to find, understand, and use health information is known as health literacy. For caregivers, this skill is not just about reading a pamphlet; it is the practical capacity to keep a patient safe and ensure they receive the right care at the right time. When this capacity is low, or when the caregiver is overwhelmed by the sheer weight of their duties, the quality of care can suffer, and the patient's journey becomes more difficult. Understanding what helps or hinders a caregiver's ability to manage these tasks is crucial for doctors and nurses who want to support families during their most vulnerable moments.
Researchers in Hangzhou, China, set out to understand the specific factors that shape this health literacy among family caregivers of patients with advanced cancer. They recruited 280 family members from a major hospital, asking them to fill out detailed surveys about their daily lives, their confidence in handling care tasks, their level of stress, and their ability to process medical information. The study focused on three main ideas: the heavy burden of caregiving, the caregiver's belief in their own ability to succeed (self-efficacy), and their level of worry about health issues (health anxiety). The team wanted to see how these elements connected to the caregivers' overall health literacy, using a statistical approach that maps out how these different factors influence one another.
The results painted a clear picture of what supports a caregiver's ability to understand and act on medical information. The average caregiver in the study scored a moderate level of health literacy, but the data revealed that this score was not random; it was deeply tied to specific life circumstances and psychological states. Caregivers with higher levels of education tended to have better health literacy, which aligns with the idea that general learning skills help in grasping complex medical concepts. More significantly, the study found that the emotional and physical load of caregiving played a major role. When the burden of care was heavy, health literacy scores dropped. It appears that when a caregiver is stretched too thin by the demands of the job, they have less mental energy available to seek out, understand, or apply new health information.
Conversely, a caregiver's confidence in their abilities was a powerful positive force. Those who felt more capable of handling care tasks also demonstrated higher health literacy. This suggests that believing one can manage the situation encourages the active engagement needed to learn and understand medical details. Interestingly, while health anxiety was linked to lower literacy when looked at on its own, it did not hold up as an independent factor once the researchers accounted for the caregiver's burden and confidence. This means that the worry itself is not the primary driver; rather, it is the overwhelming nature of the duties and the lack of confidence that truly undermine a caregiver's ability to stay informed.
The study also highlighted that these findings are specific to the group surveyed and the methods used. The research was conducted at a single hospital, and because it captured a snapshot in time rather than following families over months or years, it cannot prove that one factor causes another. For instance, while the data shows that high burden is associated with lower literacy, it does not definitively prove that the burden causes the drop in literacy, or if low literacy leads to a feeling of increased burden. However, the patterns are strong enough to suggest that nurses and healthcare providers should look beyond just the medical facts when supporting families.
For the medical professionals working with these families, the study offers a practical guide. It suggests that education should not be a one-size-fits-all approach. Instead, healthcare teams should assess not only what a caregiver knows but also how much they are struggling and how confident they feel. For those carrying a heavy load, information might need to be broken down into smaller, manageable pieces and reinforced over time. For those lacking confidence, support should focus on building their skills and reassurance. By addressing the emotional and practical weight of caregiving, medical teams can help families build the literacy they need to navigate the difficult path of advanced cancer care.
