Introduction: The disease that requires the most palliative care is cancer. Caregivers of cancer patients are estimated to spend an average of 32.9 hours per week providing complex care. Psychological problems are the most dominant issue in caregiver burden. Caregiver's Burden Scale in End-of-Life is a tool used to measure caregivers' psychological burden. The aim of this study is to determine the cross-cultural validity of the Indonesian version of the Care CBS-EOLC questionnaire among cancer patients. Method: This research employed a cross-sectional study design with a total of 169 caregivers of cancer patients. The analysis included univariate analysis, Confirmatory Factor Analysis, Exploratory Factor Analysis, and a discriminant validity test. Results: The cross-cultural validity testing of the CBS-EOLC questionnaire underwent 10 stages with correlations ranging from r = 0.243 to 0.865 and a Cronbach's alpha coefficient of 0.926. The Kaiser-Meyer-Olkin measure was 0.686 and Bartlett's Test of Sphericity was significant (p < 0.001). The study identified four dimensions and the discriminant validity test result between the CBS-EOLC and ZBI questionnaires was 0.103. Conclusion: The Indonesian version of the CBS-EOLC questionnaire is suitable for assessing the psychological burden among caregivers of cancer patients.
