FReDA-W2a - Questions about infection with and vaccination against COVID-19 (English Version)

Have you been infected with the COVID-19 virus since the start of the Corona pandemic?

[Haben Sie sich seit dem Beginn der Corona-Pandemie mit dem COVID-19-Virus angesteckt?]

Yes, confirmed by positive corona test [Ja, durch positiven Corona-Test bestätigt]
Yes, likely, but not confirmed by corona test [Ja, wahrscheinlich, aber nicht durch Corona-Test bestätigt]
No, rather unlikely [Nein, eher unwahrscheinlich]
No, almost certainly not [Nein, mit großer Sicherheit nicht]

The results of the pretest do not indicate any problems with the question, so it can be left in its current form.

Cognitive Techniques:

Specific Probes

A total of 30 of the 132 subjects reported (probable) infection with the COVID-19 virus since the onset of the Corona pandemic. Eleven of these subjects suspected infection without a positive Corona test. The aim of the cognitive pretest was to investigate the basis on which the respondents came to this assessment (N1_F1, see Appendix).
Two of the eleven subjects did not give clearly evaluable answers to the probing question. The remaining nine respondents stated that they had had symptoms typical of COVID-19 infection (n = 6) and that, in addition, individual or all family members had tested positive (n = 3):

• "I was sick at the very beginning of the pandemic and may have caught it at a fair." (TP189)
• "Because I was mildly ill in February 2020 with typical symptoms but was not tested at that time." (TP193)
• "Because everyone in the household was positive and I had symptoms.“ (TP78)
• "All family members tested positive, I had symptoms." (TP124)
