Development and validation of Self-Management Cognition Scale for Patients with Type 2 Diabetes
Objective To develop a self-management cognition scale for type 2 diabetes patients and to test its reliability and validity.Methods Following the scale development paradigm,an initial version of the Self-Management Cognition Scale for Patients with Type 2 Diabetes was developed based on protection motivation theory.Then a test version was formed after Delphi consultation and pilot survey.Two surveys on type 2 diabetes patients(n=739)were conducted in Nanjing,Jinan,and Shanghai,in order to evaluate there liability and validity of the scale.Results Exploratory factor analysis extracted 5 common factors(severity,vulnera-bility,response efficacy,self-efficacy,and response costs)from 29 items with a cumulative variance contribution rate of 70.017％.Confirmatory factor analysis showed that the model fitted well(x2/df=2.763,RMSEA=0.070,NFI=0.905,IFI=0.938,TLI=0.930,CFI=0.937).The Cronbach's α coefficient of the scale was 0.826,AVE=0.557～0.924.Conclusion The scale has good reliability and validity,which can be used for mea-suring self-management cognition level of type 2 diabetes patients.
