Abstract
The validity of a survey can be seriously undermined by nonresponse, or the inability to obtain information or correct information from respondents. This chapter considers reasons and explanations for nonresponse, and it discusses the basic priciples of several successful strategies to increase response rates as well as strategies to reduce the refusal rate. A summary of a Dutch case study is provided to show how an improved survey procedure reversed the downward trend into a high response rate.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
Application details are not available in the OpenAlex metadata.
