Validation and Evaluation of Structure of A Risk Perception Questionnaire for Nurses Based on Network Analysis
Objective To assess the structure of the Risk Perception Questionnaire for Nurses and to verify its reliability and validity,so as to provide reference for the popularization and the use of the questionnaire among nurses in military hospitals.Methods A convenient sampling method was used to collect risk per-ception data from 846 nurses across four military hospitals in Zhejiang,Jiangxi,Jiangsu and Anhui Prov-inces.The exploratory graph analysis(EGA)was used to explore the network dimensional structure of the questionnaire by constructing a risk perception network model.The network structural consistency was e-valuated and items were screened.The reliability and validity of the questionnaire were tested by the model fit indices and reliability coefficients.Results The network model contained 5 dimensions:personal security risk,physical function risk,occupational exposure risk,social mentality risk,and time risk,with 27 items.The structure consistency evaluation indexes of the revised questionnaire were all greater than 0.75,show-ing that the structure was stable.In the evaluation index of the network model,the Root-Mean-Square Er-ror of Approximation was 0.06 and the Compare Fix Index was 0.94.The Cronbach's alpha coefficient of the overall questionnaire was 0.966.The model fitting degree and reliability index were higher than those of the original questionnaire.Conclusions The revised questionnaire can be utilized to evaluate the level of risk per-ception among nurses in military hospitals because it has a more stable structure with more concise items.
