  6. Projektbeschreibung: The Pretest lab of GESIS Leibniz Institute for the Social Sciences (Germany) was assigned the task to pretest a module on the Internet of Things (IoT), so – if deemed appropriate – it can be included in future waves of the Community Survey on ICT Use in Households and by lndividuals conducted by the European Commission.
    The aim of the cognitive pretest was to optimize the questions prior to their potential administration in the actual survey and thereby to improve data quality. The inclusion of a module on IoT in the Community Survey on ICT Use in Households and by lndividuals is of interest to DG CNECT in order to monitor the evolution and adoption of recent technological solutions in this domain.
    GESIS tested an English and a German version of the module with British and German respondents (n=120) in a web survey. In total, respondents received open and closed probes for four items. Some of the items do not need to be changed but the results indicate that for a few questions the answer options, the question order, or the German translations need to be improved. The pretest report includes recommendation to further refine the questions of the module.
  7. Anzahl Testpersonen: 120
  8. Auswahl und Merkmale der Testpersonen: Quota sample
    This online pretest was fielded in Great Britain and Germany. Half of the respondents were British (n=60), the other half were German (n=60). Due to the substantive topic of this pretest (usage of internet connected devices/systems), the target population was divided into three categories (Barriers - Problems - Wearables).
    The selection of the target population was based on the quotas age (18 to 64 years in three groups: 18 – 29; 30 – 49; 50 – 64), and gender (male; female). In addition, a minimum of 15 respondents in each country was expected to fall into the category "Wearables".
