Objective To translate the Family Quality of Life in Dementia Scale (FQOL-D) from English to Chinese, and to test its reliability and validity. Methods Based on Brislin model, the English version FQOL-D was translated to Chinese through translation, retranslation, cultural adjustment and pilot study, then the Chinese version FQOL-D was used to investigate 216 family caregivers of elderly dementia patients in community to test its reliability and validity. Results The Chinese version FQOL-D was consisted of 4 dimensions (family interaction, emotional needs, life needs, dementia care） and 35 items，its I-CVI was between 0.833 and 1.000, S-CVI was 0.982. The cumulative variance contribution rate of exploratory factor analysis was 67.968%, the criterion correlation coefficient was 0.608, the Cronbach′s α was 0.972, the retest reliability was 0.943, and the split-half reliability was 0.983. Conclusion The Chinese version FQOL-D has good reliability and validity, which can be used to assess the status of family quality of life in dementia.
