Abstract

Introduction: The aim of this study was to design a standard questionnaire facilitating the evaluation of the knowledge and attitude of medical students regarding radiation protection. Methods: At first, a 30-item questionnaire was prepared. The scale construction procedure was performed using content validity assessment. Considering objectives, some items were designed based on textbooks and the ideas of oral radiologists, medical physicists, and occupational medicine specialists as the expert panel. Content validity of the draft was determined by the panel. Results: Test-retest procedure was used to determine the reliability of the questionnaire by kappa statistic and Cronbach’s alpha coefficient. Experts evaluated the content validity as desirable. Kappa coefficient was more than 0.75 for almost all knowledge and attitude items. Cronbach’s alpha coefficients for basic knowledge, practical knowledge, and attitude domains were 0.793, 0.823, and 0.822, respectively. Conclusion: The designed questionnaire was confirmed as reliable considering Iranian cultural concepts.

医学生辐射防护知识和态度调查问卷的编制

前言:本研究旨在设计一份标准问卷，以评估医学生对辐射防护的知识和态度。方法:首先编制问卷，共30项。量表构建程序采用内容效度评估。考虑到目标，一些项目是根据教科书和口腔放射科医生、医学物理学家、职业医学专家作为专家组的想法设计的。草案的内容有效性由专家组确定。结果:采用重测法，采用kappa统计量和Cronbach’s alpha系数确定问卷的信度。专家评价内容效度为可取。几乎所有的知识和态度项目Kappa系数都大于0.75。基本知识域、实用知识域和态度域的Cronbach’s alpha系数分别为0.793、0.823和0.822。结论:考虑到伊朗文化观念，所设计的问卷是可靠的。
