In collaboration with APT Film and Television, The National Centre has produced an interviewer training video which concentrates on overcoming reluctance or hesitation at the first encounter with a potential respondent. The video features four experienced interviewers at work, demonstrating their various strategies on the doorstep, and showing what they do when people are 'too busy' or 'not interested' . The location filming of doorstep behaviour is linked by a lively and informal studio discussion among the interviewers, as they share ideas and experiences, highlighting pitfalls and solutions. A Guide for Interviewers on the Doorstep' , the 30-minute video covers a wide variety of issues, including body language, entryphones, respondent selection, overcoming obstacles, and approaching older people. An ethical and professional approach is emphasised throughout.
