Abstract:
Objective:To construct an evaluation index system for risk cognition and protection capability of interns at department of radiology for ionizing radiation,and explore its value in assessing risk cognition and protection capability of interns at department of radiology for ionizing radiation.Methods:Guided by the Knowledge-Attitude-Practice(KAP)theory,the relevant literatures that were published between January 1,2014,and December 31,2024 were searched from Chinese and English databases included China National Knowledge Infrastructure(CNKI),Wanfang,VIP Chinese Scientific Journals Database(VIP)and PubMed by using keywords such as"intern,""ionizing radiation and protection,""teaching,""indicator,""Delphi method,"and"KAP theory".Preliminary evaluation indicators were drafted based on interviews with 10 staff at department of radiology of Peking University People's Hospital.The Delphi method involving 21 experts from different provinces and cities of China was conducted over two rounds to finalize the index system.An online questionnaire survey by using Questionnaire Star was adopted to distribute questionnaires with evaluation index system for risk knowledge and protection capability of interns at department of radiology for ionizing radiation,and a total of 50 interns at department of radiology from Heilongjiang,Beijing,and Guangdong were investigated by the questionnaire.Results:Both the response and validity rates of the expert inquiry letters of two rounds for evaluation index system for risk knowledge and protection capability of interns at department of radiology for ionizing radiation were 100%.Experts'authority coefficients of two rounds were respectively 0.910 and 0.928,and the coordination coefficients of experts'opinions were respectively 0.318 and 0.342.The finalized evaluation index system comprised of 3 first-level indicators(theoretical knowledge,safety culture of ionizing radiation,and operational behavior),and 10 second-level indicators,and 46 third-level indicators.The scores of interns at department of radiology for the survey questionnaire of risk knowledge and protection capability about ionizing radiation was(177.57±29.68 points),indicating they were moderate level for risk knowledge and protection capability about ionizing radiation.Conclusion:The evaluation index system for risk knowledge and protection capability of interns at department of radiology for ionizing radiation has higher scientific nature and reliability,which can provide references for assessing the relevant theoretical and operational capability of interns,and conducting training with target.
