Hello!

I want to create a questionnaire based on the Analytical Hierarchy Process (AHP) on LimeSurvey, as it is the survey platform recommended by my university.
AHP is a method that relies on pairwise comparisons, meaning that two criteria (or parameters) are compared at a time using a scale from 1 to 9. In this format, one criterion is placed at each end of the scale, and participants select the value that best represents the relative importance of one criterion over the other.
I attempted to implement this using the “array” question types in LimeSurvey, but none of the available formats seem to match what I need for a proper AHP pairwise comparison. Has anyone here used LimeSurvey to design an AHP-style pair comparison question?
I have attached an example of what a typical AHP pair comparison scale looks like. I am aiming to reproduce something very similar. The visual layout can be slightly modified, but I would like to keep it simple, user-friendly, and easy to interpret for participants.

Thank you!

Have a look at the Array type question using the Semantic Differential option.

Here it is
 
Please, read the manual
"Question type - array"  - the second example there
