Abstract: Objective To investigate the life satisfaction and its related factors in primary caregivers of breast cancer patients. Methods The Life Satisfactory Index A (LSIA) and self-administrated questionnaire were used. The life satisfaction between breast cancer patients'primary caregivers and breast benign patients' primary caregivers were compared. The factors of the life satisfaction in primary caregivers of breast cancer patients were analyzed. Results The life satisfaction was poorer in the breast cancer patients' primary caregivers than in the breast benign patients' primary caregivers (P<0.01). The life satisfaction in the breast cancer patients' primary caregivers was correlated with the stage of breast cancer, course of disease, primary caregivers' age and family monthly income (P<0.05). Conclusion The life satisfaction in breast cancer patients' primary caregivers is worse and is related with stage of breast cancer, course of disease, primary caregivers' age and family monthly income.
