Objective Our study examined the feasibility and validity of the EQ-5D-5L proxy questionnaire in measuring health-related quality of life (HRQoL) of nursing home residents. Methods Twenty-four nurses and 229 residents from 3 nursing homes in Singapore participated in this cross-sectional study. Nurses assessed residents under their care with the EQ-5D-5L proxy questionnaire. Two experienced mappers conducted Dementia Care Mapping (DCM) within 1 month in a subsample of the residents. Feasibility was evaluated according to percentage of unanswered EQ-5D-5L items and proportion of nurses who failed to respond to all items. Convergent validity was assessed by examining the correlation between EQ-5D-5L measures and DCM scores. Known-groups validity was assessed by comparing differences in EQ-5D-5L scores for residents with varying communication abilities and physical functions. Results The nurses’ mean age was 35.4 years while the residents’ was 73.4 years. Most residents were female (51.3%) and had the ability to communicate (81.3%). For 6 of the 229 residents (2.6%), not all items in the EQ-5D-5L were completed. The EQ-5D-5L index score correlated positively and moderately with the DCM’s well/ill-being score (r = 0.433, n = 90, P < 0.01). Residents who were able to communicate effectively or had better physical function were assessed to have less severe health problems and better EQ-5D-5L scores. Conclusion The EQ-5D-5L proxy questionnaire has adequate feasibility and validity when used by nurses to assess the HRQoL of nursing home residents. As it is brief and can be conveniently administered, it can be deployed on a larger scale to assess HRQoL of nursing home residents.
