Abstract:
Objective:To construct a psychological aging scale,and to provide a tool and indexes for scientific evaluation on aging.Methods:The age-related psychological items were collected through literature screening and expert interview.The importance,feasibilityand the degree of authority for the psychological index system were graded by two rounds of Delphi method.Using analytic hierarchy process,the weight of dimensions and items were determined.The analysis for internal consistency reliability,correlation and exploratory factor was performed to evaluate the reliability and validity of the scales.Results:By two rounds of Delphi method,17 experts offered the results as follows:the coefficient of expert authorities was 0.88±0.06,the coordination coefficients for the importance and feasibility in second round were 0.456 (P＜0.01) and 0.666 (P＜0.01),respectively.The consistency was good.The psychological aging scale for healthy people included 4 dimensions as follows:cognitive function,emotion,personality and motivation.The weight coefficients for the 4 dimensions were 0.338,0.250,0.166 and 0.258,respectively.The Cronbach's α coefficient for the scale was 0.822,the reliability was 0.817,the content validity index (CVI) was 0.847,and the cumulative contribution rate for the 5 factors was5 1.42％.Conclusion:The psychological aging scale is satisfied,which can provide reference for the evaluation for aging.The indicators were representative and well-recognized.
