Abstract
Anonymity is frequently offered to recipients of mail questionnaires in order to secure their cooperation and thus increase the response rate obtained. Individuals desiring to remain anonymous may, however, choose to respond differently to the instrument than known respondents because their identities are secret. Thus, a potential source of bias is introduced whenever anonymity is made available. This article examines the responses of identified and anonymous respondents to a mail questionnaire in order to determine the extent to which such bias occurred.
