Question type similar to a DualScale question type.
Difference is that you that you are not allowed to choose the same item on both scales.
Simple example would be : First scale "most important", second scale "least important". Now you show different items to choose from. With a dual scale question type it would be possible to choose the same item as "most important" AND "least important" which wouldn't allow to apply the MaxDiff method.
