The reasons for attrition: we (still) haven't got a clue

This paper describes a small survey (attrition survey) undertaken to ascertain reasons of attrition and non-response in questionnaire responses from student participants as part of a larger longitudinal survey (longitudinal study). Due to difficulties in retaining participants within the longitudinal study determining reasons for attrition and non-response became important; mainly. The questionnaire employed in the longitudinal study was developed by the Cambridge Management Institute (CMI) and is widely known as the HEGI instrument or the SPEED network questionnaire. The questionnaire was designed to be completed three times by the participants; one pre-test and two post-tests.
