Because survey respondents may not be representative of the population being studied, the external validity of many research conclusions may be of concern. Nonresponse analyses helps address this concern. The purpose of this article is to identify how frequently nonresponse analyses are reported and what variables are related to these rates. The authors find that less than one third of the survey studies include nonresponse analyses. A number of journal and article quality measures and sample characteristics were found to be related to the reporting of nonresponse analyses.
