Cognitive testing of the questionnaire developed for the 2011 Census
Between 2007 and 2010, on behalf of the Scottish Government and General Register Office for Scotland (GROS), we conducted a series of studies testing a range of questions that had been developed for Scotland's Census 2011.
Between 2007 and 2010, on behalf of the Scottish Government and General Register Office for Scotland (GROS), we conducted a series of studies testing a range of questions that had been developed for Scotland’s Census 2011. Following testing, we made a series of recommendations on how the questions could be improved.
The focus of each study was as follows:
Cognitive testing of the whole census questionnaire
The testing had two main aims: to test section H1 to H5 (the household composition section) and the accompanying guidance to ensure that it was easy to understand and answer to test that the information and questions contained in the whole questionnaire were presented as effectively as possible, within existing design constraints.
Overall, 70 cognitive interviews were conducted with a broad range of respondents. The sample was not intended to be statistically representative of the Scottish population, but was designed to include people from the main groups that we anticipated might:
- have trouble understanding the concepts of usual residents and ‘visitors’
- have difficulty correctly navigating through the questionnaire
- have difficultly understanding and following particular guidance and instructions included in the questionnaire.
- have trouble working out the meaning or intention of the question
- interpret the meaning of the question incorrectly and, as a consequence, answer differently than they might otherwise have done
- feel that having both the national identity and the ethnicity question allowed them to describe themselves more fully
- have an objection to the inclusion or phrasing of the question or inclusion or exclusion of individual response options.
- have trouble working out the meaning or intention of the question
- have difficulty selecting the accurate response option
- have difficulty locating an appropriate response option that described their situation
- Scottish Gaelic speakers
- BSL users
- ethnic minority language speakers. This included Bengali speakers, Urdu speakers and Polish speakers
- ‘Scots’ speakers.
65 cognitive interviews were conducted with a broad range of respondents in terms of ethnic background, age, sex, household living arrangements, educational attainment level and language capabilities.
