RESUMEN

Objective Patients suffering from cancer need to receive care from their family; however, their family caregivers do this without preparation or training, so their involvement in patients' care results in a caregiving burden that may affect patient's hope and quality of life (QOL). Methods This study examines the effect of caregiving burden on the QOL of cancer patients ( n = 100) with the mediatory role of hope and shame. To achieve this, Persian versions of Zarit Burden Interview, the World Health Organization QOL, Herth Hope Index, and Guilt and Shame Proneness Scale were used. Meanwhile, path regression analysis was implemented to analyze the relationship between caregiving burden and QOL. Results The results implied a relation among caregiver burden, hope, and QOL of patients diagnosed with cancer. It was found that there is a direct and negative relationship between caregiver burden and hope. In addition, there was an indirect and positive relationship between caregiver burden and QOL. Hope and QOL also had a high correlation. Besides, it was shown that there was a negative relationship between the shame experienced by patients and their hope and QOL. Conclusion caregiver burden was proved to be influential and negatively affected the factor for the QOL. Besides, patients' hope decreases while caregiving burden increases; this will in turn affect patients' recovery and their physical, mental, and cognitive functions. This study provides a foundation for future research in this critical area for oncology.
