METHODOLOGY

DS-CAPI

Since October 2003, the NRS has been conducted using Double Screen CAPI (DS-CAPI).  All prompt material is shown to respondents on a tablet screen that is controlled by the interviewer’s laptop via a radio link.

Self-Completion

From 2006, a proportion of selected persons in London, the South East and East Anglia who have not been interviewed face-to-face are sent a self-completion questionnaire by post.  Completed questionnaires have been included in the sample from April 2006 onwards.  In the period October 2010 - September 2011, 933 such questionnaires were included.

Respondent Incentives

With effect from September 2006, respondent incentives have been deployed in London.  All respondents completing a DS-CAPI interview are offered a £25 gift voucher or option for Ipsos MORI to donate this sum to one of three nominated charities on their behalf.
