Qualitative approach

  • The data was collected by group discussions.
  • The target group for this research study was members of the Scottish Public.
  • In total, 7 group discussions were undertaken.
  • Fieldwork was undertaken between 3rd to 17th February 2026.
  • Respondents were recruited by Progressive’s team of qualitative recruiters. These recruiters worked to predetermined quota controls to ensure that the final sample reflected the requirements of the project.
  • An incentive of £45 compensated respondents for their time and encouraged attendance.
  • In total, 3 moderators were involved in the fieldwork for this project.
  • Each recruiter’s work is validated as per the requirements of the international standard ISO 20252. Therefore, all respondents were subject to validation, either between recruitment and the date of the depth interview, or on the day of the depth interview. Validation involved respondents completing a short questionnaire asking pertinent profile questions and checking that they have not participated in similar research in the past 6 months.
  • It should be noted that, due to the small sample sizes involved and the methods of respondent selection, qualitative research findings do not provide statistically robust data. This type of research does however, facilitate valid and extremely valuable consumer insight and understanding.
  • All research projects undertaken by Progressive comply fully with the requirements of ISO 20252.
