Objective To develop and validate a self-reported palliative care quality scale for terminal cancer patients, and to provide a suitable tool for evaluating quality of care. Methods The initial draft of the scale was formed through literature review, group discussions, Delphi expert consultation, and pilot survey. A total of 238 and 254 terminal cancer patients were surveyed for testing reliability and validity of the scale and for validation the scale. Results The scale consisted of 39 items across 5 dimensions. Explo-ratory factor analysis identified five factors, contributing to a cumulative variance of 74.433%. Model fit indices for the confirmatory factor analysis demonstrated a well-fitting model (χ2/df=1.721, GFI=0.921, NFI=0.925, CFI=0.963, TLI=0.943, and RMSEA=0.054). The overall Cronbach′s α coefficient of the scale was 0.950, split-half reliability was 0.927, test-retest reliability was 0.830, and content validity index was 0.950.Conclusion The scale exhibits favorable reliability and validity and can be used to assess the quality of palliative care for terminal cancer patients.
