Context: The Functional Assessment of Chronic Illness Therapy-Palliative Care (FACIT-Pal) has been widely used in assessing the quality of life (QOL) of patients with life-limiting illness. However, the Chinese version of the FACIT-Pal has not been psychometrically validated yet. Objectives: The purpose of this study was to psychometrically validate the FACIT-Pal in Chinese patients with advanced cancer. Methods: 160 patients with advanced cancer in mainland China participated in this cross-sectional study. The scalability of the instrument was determined by the item-total correlations and the reliability was tested by examining the Cronbach's alpha coefficients. The construct and concurrent validity of the FACIT-Pal were also examined. Results: The item-total correlation coefficients ranged from 0.25 to 0.72 (P < .01). Cronbach's alpha coefficient of the Chinese version of the FACIT-Pal was 0.94, ranging from 0.78 to 0.89 for subscales. Confirmatory factor analysis (CFA) results provided support for the measurement structure of the 26-item Functional Assessment of Cancer Therapy-General (FACT-G). Exploratory factor analysis (EFA) of the 19-item palliative care subscale identified five factors accounting for 62.21% of the total variance. Total/subscale scores of the FACIT-Pal were positively correlated with that of the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being 12 Item Scale (FACIT-Sp-12) (r = 0.338–0.811, P < .01), as well as with the Karnofsky Performance Scale (KPS) scores (r = 0.163–0.273, P < .05), except for the correlation between social/family well-being subscale score and KPS score. Conclusion: The Chinese version of the FACIT-Pal demonstrates desirable psychometric properties for evaluating QOL in Chinese patients with advanced cancer.
