Abstract:
Objective To develop and test the reliability and validity of the Intrinsic Capacity Assessment Scale for the Older People,so as to provide an effective tool for the assessment of the intrinsic capacity of the aged.Methods Based on the International Classification of Functioning,Disability and Health(ICF)as the theoretical framework,the initial version of The Intrinsic Capacity Assessment Scale for the Older People was developed through literature analysis,Delphi expert consultation and pre-survey.From July to September 2023,650 old people were selected by convenience sampling method to conduct a survey,and 20 old people were surveyed after 2 weeks again to test the reliability and validity of the scale.Results The effective questionnaire recovery rates of the 2 rounds of expert correspondence were 92.3％and 91.7％;the expert authority coefficients were 0.83 and 0.86;the mean importance scores of items were 2.04-3.79 and 3.50-3.82,and the full score ratios were 4.2％-83.3％and 54.6％-86.4％,respectively.The coefficients of variation were 0.11-0.42 and 0.11-0.23,respectively.A total of 5 common factors were extracted from exploratory factor analysis,and the cumulative variance contribution rate was 68.327％.The results of confirmatory factor analysis showed that the fit indexes were x2/df=1.908,RMSEA=0.054,CFI=0.931,IFI=0.932,TLI=0.922,indicating a good fit.The Cronbach's α coefficient of the scale was 0.944;the split half reliability was 0.806;the retest reliability was 0.933.The content validity index of item level was 0.82-1.00,and the content validity index of scale level was 0.91.The Intrinsic Capacity Assessment Scale for the Older People included 35 items in 5 dimensions:movement,vitality,sensation,cognition and psychology.Conclusion The Intrinsic Capacity Assessment Scale for the Older People has good reliability and validity,and it can be used as a reliable tool to evaluate the intrinsic capacity level of the aged.
