Reliability and validity of Ambivalent Ageism Scale in community-dwelling older adults
Objective To test the reliability and validity of the Ambivalent Ageism Scale(AAS)among community-dwelling older adults in China.Methods Totally 377 community-dwelling older adults from January to April 2023 were randomly selected from 3 communities of Jinan city by convenience sampling to test the reliability and validity of the AAS.Results The Chinese version of AAS consisted of 3 dimensions,involving 12 items after 1 item was removed.In terms of content validity,I-CVI was 1.000,and S-CVI/UA 1.000.Exploratory factor analysis fixed 3 common factors,accounting for 68.351％of the cumulative contribution of variance.By confirmatory factor analysis,the model fitting index(x2/df=1.534,RMSEA=0.047,CFI=0.991,TLI=0.988,SRMR=0.020)suggested good structural validity.SRW was between 0.815 and 0.919;when AVE=0.726,0.811,0.797,CR=0.841,0.963,0.940.AVE square root(0.852～0.901)was greater than the correlation coefficient among each dimension(0.560～0.574)(P＜0.001),showing good convergent validity and discriminatory validity.The scale had positive correlation with the total score of the Everyday Ageism Scale(r=0.702,P＜0.001),indicating good criterion validity.In terms of reliability,the internal consistency reliability coefficient of the scale was 0.902;the Guttman split-half reliability coefficient 0.774;the Omega combination reliability coefficient 0.890,and the 4-week test-retest reliability 0.780.Conclusion The Chinese version of the AAS is reliable and valid,which is an effective tool for measuring the attitudes of the hostile ageism and benevolent ageism of the community-dwelling older adults in China.
