Operational guidance document on measuring personal consumer detriment : developed as part of the study on measuring consumer detriment in the European Union

This guidance document has been developed with the aim of guiding assessments of personal consumer detriment, whether EU-wide in-depth consumer market studies focusing on a single market or cross-market assessments, based on the work undertaken in the context of the Study on measuring consumer detriment in the European Union (hereafter also referred to as 'the consumer detriment study'). It explains the methodological steps and market-specific adaptations to employ for the development of the consumer survey questionnaire and assessment of personal consumer detriment based on the data collected, and provides advice regarding the use of complementary tools and approaches for the triangulation and extrapolation of results.
