METHODOLOGY
DS-CAPI
Since October 2003, the NRS has been conducted using Double Screen CAPI (DS-CAPI). All prompt material is shown to participants on a tablet screen that is controlled by the interviewer’s laptop via a radio link.
Self-Completion
In 2006-2011, a proportion of selected persons in London, the South East and East Anglia who were not interviewed face-to-face were sent a self-completion questionnaire by post. Completed questionnaires were included in the sample for the period April 2006 – December 2011.
Respondent Incentives
With effect from September 2006, participant incentives have been deployed in London. All participants completing a DS-CAPI interview are offered a £20 gift voucher or option for Ipsos MORI to donate this sum to one of three nominated charities on their behalf.
With effect from April 2012, participant incentives have also been deployed in the South East. All participants completing a DS-CAPI interview are offered a £20 gift voucher or option for Ipsos MORI to donate this sum to one of three nominated charities on their behalf.
