Unit and Item Nonresponses and Ancillary Information in Web- and Paper-Based Questionnaires Administered to School Counselors.

This study examined unit and item nonresponse rates and ancillary information provided for Web- and paper-based versions of a questionnaire administered to school counselors. Results indicate that the unit nonresponse rate was higher for the Web-based version but that the patterns of item nonresponse found generally did not differ between the media. Implications for counselors are discussed. [ABSTRACT FROM AUTHOR]
