Increasingly, [people] are refusing to participate in consumer surveys. A truly representative survey may be unattainable… The New York Times June 2004
Status of Survey Nonresponse Falling cooperation rates in the developed world (de Leeuw and de Heer, 2002) Greater decline in one-time surveys vs. longitudinal surveys (AAPOR, 2003) Greater decline in unit nonresponse than item nonresponse
The professional sophistication of Advanced Practice RNs led us to believe that an electronic survey would be appropriate, and the electronic format offered advantages over paper.
The history of nurse response rates 40% led us to believe we would have strong participation.
The response rate was disappointingly low. 13% In desperation, nurses were randomly selected from the mailing list and asked why they did not participate in the study. TOO BUSY was the recurring theme in the explanations offered.
How do We Get People to Complete Our Surveys and Provide us with Good Information ??
Techniques for Generating Higher Response Rates l Preliminary or Advance Notification l Follow-ups l Appeals l Postage and Mailing Classes l Personalization l Incentives
