However, a nonresponse bias
is a concern with this response rate.
Furthermore, the weighting method used for adjustment might not have fully controlled for nonresponse bias
, they said.
Two types of bias were of concern and were examined before further analysis was conducted: nonresponse bias
and common method bias.
Previous studies have used comparisons between early and late responders to look at nonresponse bias
(Dooley & Lindner, 2003; Jordan, Walker, Kent, & Inoue, 2011), a method based upon the assumption that late respondents are most similar to nonrespondents (Armstrong & Overton, 1977; Miller & Smith, 1983).
The first several chapters deal with the basics of collecting reliable data, including how to get a good sample, correct for nonresponse bias
, and understand types of potential error.
It is nonresponse bias
that is the focus of this editorial and it is also the subject of the paper by Halbesleben and Whitman (2013) that this editorial accompanies.
Neither the subscale scores nor the overall scale score differed between respondents to the first postal mailing and the second postal mailing, which may help to offset potential concerns about nonresponse bias
Since only 63% of hospitals responded to the AHA's Annual Survey's Information Technology Supplement, there is the potential for a nonresponse bias
in our results.
was assessed by comparing the responses of the early and late respondents based on the method presented by Smith et al.
There is empirical evidence that the reduced risks were attributable partly to nonresponse bias
(Vrijheid et al.
Assessing response rates and nonresponse bias
in Web and paper surveys.
To determine whether nonresponse bias
affected the results, we also calculated all PPVs after adjusting for potential nonresponse bias
(results not shown).
