Empfehlungen:Question: The question should be supplemented by a definition of what is meant by “a serving of fruits or vegetables.” A possible formulation can be found in the recommendation on question 3.
Furthermore, the question could be simplified grammatically:
"How often do you consume a serving of fruits or vegetables in a regular week?”
[„Wie oft nehmen Sie in einer normalen Woche eine Portion Obst oder Gemüse zu sich?“]
Response options: We recommend making the answer options uniform and either write out "three to six times" [„Drei- bis sechsmal“ ] or write all response options as numbers.
Eingesetzte kognitive Technik/en:Emergent Probing
Befund zur Frage: Since the explanation is only given in question 3, do the respondents have difficulties in defining a “serving” in question 2?
None of the respondents asked what was meant by "a serving of fruit or vegetables" in this question or commented otherwise on the lack of a definition of a serving. However, to ensure that respondents in the main survey are thinking of comparable servings, we recommend adding an explicit definition to the question.
