摘要
目的通过电子问卷来收集数据日趋普遍,针对电子问卷质量,分析两种不同质控方式的效果,并探讨被访者特征对电子问卷调查质量的影响,为后续制定电子问卷调查质控标准、提升网络问卷调查质量提供科学依据。方法分别以作答时间(过短则不合格)、质控问题(未选择指定选项则不合格)为标准衡量电子问卷质量,利用5135份社区居民新冠疫情相关知识的网络问卷调查,分析问卷中被访者特征对网络问卷质量的影响。结果以质控问题、作答时长单独为标准时,问卷合格率分别为67.6%和96.1%;两者联合质控的问卷合格率为65.0%。多因素Logistic回归分析显示,以质控问题为标准时,女性(OR=1.26,95%CI=1.11~1.44)、文化程度高(本科及以上学历,OR=1.46,95%CI=1.15~1.85)者的问卷质量较高;以作答时间为标准时,文化程度高(本科及以上教育水平,OR=0.12,95%CI=0.02~0.39)、学生(OR=0.43,95%CI=0.28~0.64)的问卷质量更低,而年龄更高者问卷质量越高(50岁以上,OR=19.33,95%CI=5.09~93.41)。结论作答时间和质控问题两种质控方法的问卷合格率不同、影响因素差别较大,说明仅使用一种质控方式的质控效果可能不够全面,应考虑结合多种质控方式、设置合理的质控标准。
Objective Collecting data through web-based questionnaires is becoming more and more common.In order to evaluate the quality of web-based questionnaire responses,this study aims to analyze the effects of two quality control methods,and to explore the influence of subjects'characteristics on the quality of web-based questionnaires,so as to provide a scientific basis for the subsequent development of quality control standards for web-based questionnaires and the improvement of the quality of web-based questionnaires.Methods The quality of the web-based questionnaire is measured by the answering time(if the answer time was too short,it was unqualified)and the quality control questions(if the specified option was not selected,it was unqualified).By using the results from the investigation on 5,135 community residents about their knowledge of the COVID-19,the influencing of subjects'characteristics in the questionnaires on the quality of web-based questionnaires was analyzed.Results The qualified rate of the questionnaire was 67.6%and 96.1%with quality control questions and response time,respectively.Combining both standard,the qualified rate was 65.0%.The results of the multifactorial logistic regression analysis showed that,when the quality control question was used as the criterion,the quality of the questionnaire was higher for female(OR=1.26,95%CI=1.11-1.44),high educational level(undergraduate or above,OR=1.46,95%CI=1.15-1.85).When taking the answering time as the standard,people with higher the education level(undergraduate education level and above,OR=0.12,95%CI=0.02-0.39),students(OR=0.43,95%CI=0.28-0.64)had lower quality questionnaires,while the questionnaire of older people(over 50 years old,OR=19.33,95%CI=5.09-93.41)had higher quality.Conclusion The different passing rates and influencing factors of the questionnaires with two quality-control methods(response time and quality-control questions)indicate that the quality-control effect of using only one quality-control method may not be enough,and consideration should be given to combining multiple quality-control methods and setting reasonable quality-control standards.
