Construction,reliability and validity of a professional identity questionnaire for psychiatrists
Background Domestic researches on the professional identity of psychiatrists are still relatively rare up to now,and effective evaluation tools remain inadequate.Objective To construct a professional identity questionnaire for psychiatrists with high reliability and validity,so as to provide an effective tool for the evaluation of professional identity of psychiatrists.Methods A self-designed questionnaire titled"Professional Identity Questionnaire"was compiled.After preliminary screening of items and expert consultation,an initial questionnaire was formed and administered to a sample of 400 psychiatrists,and the final questionnaire was assessed by item analysis,reliability analysis and validity analysis.Results The Cronbach's α coefficient was 0.930 for the final questionnaire,and ranged from 0.817 to 0.920 for each dimension.The value of KMO was 0.904(χ2=2 931.652,P<0.01).The cumulative variance contribution rate of factors extracted from exploratory factor analysis was 68.306%.Confirmatory factor analysis showed that the integrity of fit indexes were χ2/df=1.234,GFI=0.905,NFI=0.916,RMSEA=0.036,CFI=0.983,IFI= 0.983.The final version of the professional identity questionnaire for psychiatrists consisted of 23 items relating to 4 dimensions,namely,professional cognition,professional behavior,professional emotion and professional values.Conclusion The professional identity questionnaire for psychiatrists has good reliability and validity,and can be used as an effective tool to evaluate the professional identity of psychiatrists.
