ANNEX B: SURVEY ADMINISTRATION
B.1 An advance letter was sent to all sampled households from the Scottish Executive. The letter was printed on headed paper and signed by the Managing Director of Ipsos MORI. Because the Postal Address File does not identify the names of householders, the letters were addressed to 'Dear Householder'. The advance letter was designed to provide basic information about the survey, but to avoid giving prominence to the issue of mental health. The copy of the advance letter can be found in Annex A.
B.2 A contact sheet was designed and printed for each address in the sample, 2,372 in total. The contact sheets acted as a record of each visit for each selected address. It was fully data entered to record information on the number of calls made to achieve an interview, as well as the day and time of each interview. In addition it recorded important information on the outcome of the interview, i.e. successful interview, refusal information, no contact or other as tables C.1, C.2 and C.3 show.
B.3 All fieldwork on this project was conducted by Ipsos MORI's fully trained fieldforce. All interviewing on this project was conducted using CAPI (Computer Assisted Personal Interviewing). Interviewers were instructed to download their successful interviews at the end of each day so that the project team could monitor progress throughout fieldwork. Interviewers were also instructed to return all contact sheets (successful and otherwise) to the Ipsos MORI field department in London so that the data could be entered to monitor progress.
