Development and validation of a questionnaire to evaluate the demand for communi-ty medical-nursing combined services among urban empty-nest older adults
Objective To develop a questionnaire to evaluate the demand for community medical-nursing combined services among ur-ban empty-nest older adults and to test its reliability and validity.Methods Based on the Maslow's Hierarchy of Needs theory and the Active Aging theory,a draft of the questionnaire was formulated after literature review,qualitative interviews,and expert con-sultation,then a cross-sectional survey with 495 urban empty-nest older adults was conducted to test the reliability and validity of the questionnaire.Results The final version of the questionnaire included eight dimensions and 37 items,which accounted for 65.559%of the total variance in exploratory factor analysis.The item-level content validity index(CVI)ranged from 0.824 to 1.000,and the scale-level CVI was 0.930.The overall Cronbach's α coefficient was 0.966.Confirmatory factor analysis indicated good model fit(x2/df=1.236,RMSEA=0.033,SRMR=0.030,CFI=0.982,TLI=0.980,IFI=0.982).Conclusion The ques-tionnaire is reliable and valid to assess demand for community medical-nursing combined services among urban empty-nest older adults.
