    1. Recommendations: Question: No changes recommended.
      Answer categories: No changes recommended.  
  1. Cognitive Techniques:Information image/link to cognitive pretesting No direct probing.
    Question Z3 included an “Other“ answer option so that respondents could type in additional purposes that were not mentioned in the answer categories. The goal of this “probe”/answer option was to find out whether the list of answer options is exhaustive and clear.
  2. Findings for Question: Only respondents who said that they have used wearable devices connected to the internet (question Z1, answer option e)) received this question (UK: n=19, DE: n=15). Question Z3 asked respondents for what purposes they have used the wearable devices. Due to the possibility to select multiple answer categories, percentages do not add up to 100 percent.
    In both countries, the most frequently selected answer options were “track movement” (UK: 78.9%, DE: 73.3%), “health management” (UK: 57.9%, DE: 60.0%), and “make or receive phone calls…” (UK: 52.6.9%, DE: 46.7%).
    Neither the British nor the German respondents mentioned any “other purposes” that were not already included in the list of answer categories. This result suggests that the list of answer options is exhaustive and clear to respondents.
  1. Question Topic: Digitalization/ Use of digital systems
