Question: We recommend rewording the question to ask for the past seven days, as this time period is clearer and may make it easier to answer the question.
Instruction: We also recommend adding an instruction on the format of the answer: "Please enter a number between 0 and 7."
Response format: If the fill-in instruction is added, the "not seen or read in the past week" re-sponse option should be deleted. However, if the response option is to be retained, which we strongly discourage, it should be reworded:
"not seen or read any posts about political issues in the past seven days."
1. How do respondents go about answering the question?
Most respondents (n = 8) said that they first considered how often they normally visit social network sites and then how often they encounter political content. They had not explicitly thought about the time period "in the past week" mentioned in the question, but this did not seem to affect the accuracy of their answers due to the regularity with which the persons used social networks:
Only persons 01 and 10 explicitly thought about their behavior in the past week when answering the question:
"Now I have briefly thought about what was so extreme in the last week, and there was just the Corona topic again very high up. [...] I'm only starting from Facebook now, because I'm only there. As far as something like that is concerned, you've seen a lot of reports about Corona and the whole best ends." (TP 01, response: 4 days)
2. How difficult is it for the respondents to answer the question?
With the exception of subject 03, all persons found the question to be "very easy" (n = 5) or "rather easy" (n = 4) to answer, especially based on the regularity with which they used social networks (or did not use them at all):
Respondent 03 found it "rather difficult" to answer the question due to the specification of an exact number of days: "That I should specify the exact number of days, I find that difficult."
3. How do the respondents interpret the instruction "in the past week"?
Slightly more than half of the persons (n = 6) interpreted the period "in the past week" as the span of the past week from Monday to Sunday:
"The past week from Monday to Sunday." (TP 07)
In contrast, four persons (TP 02, 04, 06, 09) understood it to mean the past seven days:
"From today one week back, that is, until last Friday." (TP 02)
The phrase "in the past seven days" was judged by the respondents to be more precise and thus easier to answer:
4. Other noticeable problems
Respondents who have not seen or read any posts about political issues on social networks in the past week can answer the question in two ways. First, they can insert a zero in the open response field (like TP 07) or check the response option "not seen or read in the past week" (like TP 05). To facilitate data preparation and analysis, this could be standardized, e.g., by adding a fill-in instruction instead of the additional answer option: "Please enter a number between 0 and 7."
