Research examining relations between work group diversity and outcome measures often relies on diversity scores that are calculated on the basis of individual responses to organizational surveys. When employees fail to respond to a survey, however, the resultant diversity score representing their group will be somewhat distorted. The authors conducted a series of computer simulations to examine the extent to which correlations between group diversity scores (derived from continuous or categorical variables) and outcome variables were attenuated by various forms of random and systematic participant nonresponse. Results indicate that random nonresponse, and many forms of systematic nonresponse, substantially attenuate mean observed correlations.

Key Words: diversity • groups • missing data • nonresponse • response rate
