Scottish Environmental Attitudes and Behaviours Survey 2008 - Technical Report



5.1 As all interviews were conducted using Computer Assisted Personal Interviewing ( CAPI), interviewer and respondent errors were minimised by ensuring, through automatic routing, that the script takes the interviewers directly to the correct questions, driven by earlier responses to questions. This helps to ensure the data is complete, minimising the need for corrective editing.

5.2 The process for interpreting and coding open text responses was a manual one. As there were no completely open questions in the CAPI script, the coding required was minimal. Coding frames were drawn up based on a systematic analysis of responses from the first 100 completed interviews. These were then tested to see if these code-frames worked on the next set of 100 answers to ensure that they covered the needs of the survey (i.e. there would be no 'others' or 'other specify' answers exceeding 10%) and amended where necessary.

5.3 Established procedures for checking the consistency of the open-ended response coding were used. These checks involved 10% of all open-ended responses being blind coded by a separate coder and the resulting codes compared. Responses to questions were also reviewed ensuring that any possible back-coding into the pre-code list had been undertaken.

5.4 For the purposes of analysis, computer tables were prepared to a specification agreed with the Scottish Government. In the tables, responses to each survey question were analysed against a number of variables, namely:

  • sex
  • age (four groups: 16 to 24 years, 25 to 34 years, 35 to 54 years, and 55 years and over)
  • employment status (four groups: working, not working, studying/training scheme, retired, plus breakdown of working into full-time and part time)
  • children in household (two groups: yes and no)
  • socio-economic group of chief income earner (two groups: ABC1 and C2DE 12)
  • most important issue facing Scotland (two groups: mentioned environment, didn't mention environment)
  • tenure (four groups: owner occupier, rent from social landlord, rent from private landlord, other)
  • dwelling type (two groups: house or bungalow, and flat maisonette or apartment)
  • car in household (two groups: yes and no)
  • household type (eight groups: single adult, small adult, single parent, single pensioner, small family, older smaller households, large adult household, large family)
  • highest level of qualification obtained (five groups: Degree or professional qualification, HNC/ HND or equivalent, Higher, A level or equivalent, O, Standard Grade or equivalent and no qualifications)
  • typology of environmental engagement (five groups: Deep Greens, Light Greens, Shallow Greens, the Distanced and the Disengaged)
  • use of greenspace (four groups: everyday, at least once a week, less often than once a week and not at all)
  • wellbeing (Satisfaction with life scale ( SWLS) - three groups: satisfied, neutral and dissatisfied) 13
  • 6-fold Urban/Rural indicator (two groups: urban and rural) 14
  • Scottish Index of Multiple Deprivation ( SIMD) (three groups: most deprived 20% datazones, least deprived 20% datazones and others).

5.5 In addition to the general tables, the data was exported to SPSS. The data file was provided to the project manager at the Scottish Government as a SPSS sav file.
