   1. Findings for Multi-Item Scale: Question 5 inquired how often a variety of activities have been part of the respondents’ main paid job in the last 12 months. 26 respondents (14 English speaking respondents and 12 German speaking respondents) did not receive question 5 due to the filter in question 3. That is, only respondents that selected “yes” at the question whether they use computers, laptops, smartphones, or other computerised equipment at work, received question 5.
      
      In total, this item battery asked for 11 different activities. For each question of this item battery, the respondents had to choose between the answer categories “Daily,” “Less than daily,” and “Never.” All categories were exclusive categories and, therefore, percentages add up to 100 percent. In order to avoid respondents’ frustration due to too many probes in this web survey, the decision was made to only probe two items instead of probing all 11 items of this battery. One of the probes (Probe 6) asked the respondents whether they perform any further digital activities that were not mentioned in the previous question.
      
      The intention of Probe 6 was to check whether respondents thought that certain tasks are not covered by the items a) to k) of question 5 and to assess whether additional items need to be added to this item battery. Probe 6 asked the respondents whether they perform any further digital activities that were not mentioned in the previous question. In order to avoid confusing the respondents and in order to keep the response burden as low as possible to prevent respondents’ frustration, only respondents that chose the answer category “never” at item 5e), received Probe 6. Therefore, only participants that did not receive Probe 5 responded to Probe 6. In total, 18 British respondents and 17 German respondents provided an answer to Probe 6.
      
      Most respondents from both countries indicated that they could not think of any further digital activities that were missing in the previous question (British respondents: 83.33 percent, German respondents: 58.82 percent). However, German respondents also mentioned the digital activity of creating lists and documents (1 respondent) and talking with customers online (1 respondent). In contrast, British respondents also referred to emailing tenants and suppliers (1 respondent), gaming (1 respondent), and using the internet as a source of music (1 respondent).
      
      For a more detailed breakdown of the respondents‘ answers please refer to the tables in the attached PDF document.

   1. Recommendations for Multi-Item Scale: Question: The question text in German differs from the English source question. In the German version, respondents are asked to report on “Internet-Aktivitäten” [internet activities]. In the English version, respondents are only asked for “activities.” However, the items f)-k) are activities that do not necessarily presuppose working online. The difference in question wording could be an explanation for the differences between German and British respondents in the frequency distribution of the items f)-k). Therefore, we recommend deleting the word “internet” in the German version:
      “Wie oft waren die folgenden Aktivitäten in den letzten 12 Monaten Teil Ihrer bezahlten Hauptbeschäftigung?“
      Answer categories: No changes recommended.
