Factors affecting response rates of the web survey: A systematic review

The lower response rate in web surveys has been a major concern for survey researchers. The literature has sought to identify a wide variety of factors that affect response rates in web surveys. In this article, we developed a conceptual model of the web survey process and use the model to systematically review a wide variety of factors influencing the response rate in the stage of survey development, survey delivery, survey completion, and survey return. Practical suggestion and future research directions on how to increase the response rate are discussed. (C) 2009 Elsevier Ltd. All rights reserved.
