Johnson (1994) discusses this aspect together with a consideration of the motivation of the respondent in returning postal questionnaires  (p 41-42).  These are just as applicable to this investigation.  In terms of motivation six points are made.  The first three cover the researcher conveying the purpose, use and administration of the investigation.  The second group of three points concerns the practicalities of completing and returning the questionnaire.  At the SCC meeting of xx October 2000, the researcher took time to explain the nature of the investigation, echoing information the researcher gave at a previous meeting at the beginning of term where the investigation was first discussed.  The SCCs 
were asked to explain to their team the nature of the investigation, and encourage members to complete them in confidence.  SCCs were fully versed in how to complete the questionnaire.  Depositing completed questionnaires in the researcher’s pigeonhole in the staffroom presented an easy and anonymous means of return.
