This study sought to confirm the differences in the factor structures between the original CQOLC and a Taiwanese (Mandarin) version. Methods: A total of 183 caregivers from a cancer center in Singapore participated in this exploratory cross-sectional study. All participants completed the CQOLC and a sociodemographic form; 30 participants repeated the CQOLC twoweeks later. Results: Test-retest reliability was adequate for the CQOLC; however, confirmatory factor analyses did not support either the original four-factor model or the Taiwanese five-factor model. Exploratory factor analyses suggested the retaining of five factors to form a 25-item Singapore version (CQOLC-S25): burden, physical/practical concerns, emotional reactivity, self-needs, and social support. Inter-factor and factor scale correlations were positively significant for all factors except Support, which was negatively correlated with emotional reactivity and self-needs. Conclusions: Cross-cultural differences, which require further investigations, appear to underlie the utility and understanding of the CQOLC. More research is needed to better understand the needs of Singapore caregivers.
