This study aims to investigate the relationship between caregiver burden and health literacy among primary caregivers of patients with chronic diseases presenting to the emergency department. The study will be conducted in the Emergency Department of Yalova Training and Research Hospital and will include at least 300 caregivers. Data will be collected using a sociodemographic questionnaire, the Turkish Health Literacy Scale-32 (THLS-32), and the Zarit Burden Interview (ZBI). The findings are expected to contribute to a better understanding of caregivers' needs and to clarify the role of health literacy in caregiver burden among those providing care for individuals with chronic illnesses.
