Hi
@BoW -- honestly, you have a lot of question elements
and response choices, which is going to make it harder for respondents. Here are two things I would consider:
1. Break the question into at least two blocks. You're asking respondents to evaluate 11 separate parameters, which is a lot. If you break it into two questions, you're asking them to consider five or six options at a time, which is a lot easier.
2. Also consider reducing your Likert scale (at least that's what it looks like) to five points from seven. You still have the benefit of a central measure, but the layout is less complicated.
I hope this helps!
