Abstract:
OBJECTIVE To provide re ference for accurate measurem ent of population health status ，pharmacoeconomic evaluation and guidance of health resource allocation. METHODS Using quota and convenient sampling ，five administrative villages were selected from the rural areas under the jurisdiction of Liuzhi special zone ，Qianxi city and Jianhe county of Guizhou province from July to September 2020. Based on the gender and age ratio quota of rural population in the results of the national census，330 respondents were selected for questionnaire survey. The contents of the questionnaire included the self-made scale containing sociodemographic characteristics and general health information ，five-level EuroQoL five-dimension questionnaire （EQ-5D-5L，hereinafter referred to as the “new dimension scale ”）with cognitive dimensions （including attention ，memory， computing ability and learning ability ）and mini-mental state examination （MMSE）. The effects of reliability ，validity and new dimensions of new dimension scale on respond ents’quality of life were investigate ，and its measurement characteristics were verified；the application value of it in pharmacoeconomic hy_cheer@126.com evaluation and guiding the allocation of health resources were explored. RESULTS A total of 330 questionnaires weredistributed，320 were recovered and 320 were effective. The recovery rate and effective rate were 96.97％ and 100％ respectively. The ceiling effect of new dimension scale was 13.44％，the split-half reliability was 0.821，and the overall Cronbach ’s α was 0.852. Exploratory factor analysis showed that the new dimension scale was loaded with physiological ，cognitive and psychological factors ，and the cumulative contribution rate was 69.35％. The correlation coefficient between the new dimension and the dimension of MMSE scale were 0.19-0.61，showing a moderate or medium to strong correlation （P＜0.01）. Compared with EQ- 5D-5L，after adding each dimension ，the interpretation ability of the regression model was improved by 5.00％-17.50％. CONCLUSIONS The new dimension scale has high feasibility ，good reliability and validity ，significantly reduces the ceiling effect of EQ- 5D-5L，has higher sensitivity to the evaluation of people ’s quality of life，and can better evaluate the quality of life of rural population. It is suggested that it can be applied for quality of life evaluation，intervention effect analysis and related economic evaluation.
