四维职业认同感量表在护士群体中的修订及信效度检验OA

Objective:To revise and validate a scale based on the existing four-dimensional structure model of pro-fessional identity(comprising professional will,professional intention,professional value,and professional efficacy),providing a standardized tool for accurately assessing the professional identity level of nursing staff.Methods:An ini-tial item pool was constructed through literature review and semi-structured interviews,and the initial scale was es-tablished after two rounds of Delphi expert consultation.Using a multi-stage sampling strategy,227 nurses from a tertiary hospital in Guangdong Province were effectively surveyed during the pre-test phase.Items were screened through item analysis(critical ratio method,item-total correlation,CITC).In the formal survey phase,421 nurses from 21 hospitals across six major administrative regions in China were effectively surveyed.Psychometric properties of the scale were systematically tested using exploratory factor analysis(EFA)and confirmatory factor analysis(CFA).Results:The final version of the Four-Dimensional Nurse Professional Identity Scale retained 12 items,cov-ering four dimensions.EFA showed that the four factors cumulatively explained 79.731％of the variance.CFA dem-onstrated excellent model fit(x2/df=1.186,RMSEA=0.021,CFI=0.997,TLI=0.996,IFI=0.997).Criterion validi-ty was significant,with high correlations to the Liu Ling version(r=0.798)and the Zhao Hong version(r=0.826)(P＜0.001).The total scale's Cronbach's α coefficient was 0.908,and the Cronbach's α coefficients for each dimension ranged from 0.847 to 0.874.Conclusion:The revised 12-item Four-Dimensional Nurse Professional Identity Scale exhibits excellent reliability and validity,combining measurement precision with clinical practicality.It is suitable for rapid screening of professional identity among nurses and provides tool support for future research.
