The research team of Professor Xu Jianhua analyzed articles using questionnaire surveys published between 2014 to 2016 and included in 11 Chinese Social Science Citation Index(CSSCI)periodicals on library science from the perspectives of survey object, samples size, research topic, compliance to standards and statistical methods used. It is found that questionnaire survey has been more and more widely used in library science research. However,there are still weaknesses such as the concentration on limited number of research topics,the lack of pre-test,reliability and validity tests,analyses not in-depth,etc.;and the writing style needs to be improved.
