Aging is a progressive process that frequently necessitates the support of family caregivers. Assuming this role imposes a multifaceted pressure known as caregiver burden, which severely threatens the caregivers’ quality of life and psychological well-being. Given the growing aging population and the limitations of formal support systems, the present study aimed to investigate the effectiveness of psychological capital training (enhancing hope, resilience, and self-efficacy) on reducing caregiver burden and improving psychological well-being.

This study utilizes a quasi-experimental design, specifically a pre-test/post-test model with a control group and a one-month follow-up. The statistical population consists of all female family caregivers of older adults in Yazd Province. To this end, a sample of 30 individuals was selected via convenience sampling and randomly assigned to either the experimental or the control group (15 participants per group). Data will be collected using the Zarit Burden Interview (ZBI) and Ryff’s Psychological Well-Being (PWB) Scale. The training intervention will be administered to the experimental group over ten 90-minute sessions. Finally, the Analysis of Covariance (ANCOVA) will be employed to analyze the data and evaluate the effectiveness of the intervention.
