Score in MaxDiff type question | XM Community
Skip to main content

Hi,

I am looking for a solution to implement a score for MaxDiff type question.
I have a set of Best Worst questions, which lists several attributes that follow a specific design, according to which a subset of the attributes is presented in each question. Let's assume for example that the full set of attributes is: {Restaurants, Cafes, Hotels, Roads, Hospitals}.
In the first question, respondents should select the Best/Worst among: {Restaurants, Cafes, Hotels}
In the second question, the subset includes {Hotels, Roads, Hospitals}
The third question includes {Restaurants, Roads, Cafes}

I would need to count how many times each attribute has been chosen as Best and Worst, so I would need to create two counting variables that I can transform after into a single score.
Reason why is that I would need to display further questions based on the attribute with the highest/lowest score.

I would appreciate any suggestion.


As scoring is not available for Max diff question, this is possible either using branch logic with multiple combinations or using JS. In either of the case create attributes*2 ED in the survey flow. Now either using branch logic increment them (time consuming) or using JS you can increment them on the fly.

Thanks rondev.
I am aware that the score is not available for Max diff question and therefore I was trying to create counting variables.
Branch logic is unfeasible as I have too many attributes. I am looking at implementing JS but it seems like I am doing something incorrect as I cannot update the counting for the variable Best.
After creating the ED countRest, I am using this code in the addOnUnload section of the max diff question:

if ("${q://QID1/ChoiceGroup/SelectedChoicesForAnswer/1}" == "Restaurants") {
  var countRest = countRest + 1;} 
else { var countRest = countRest + 0;}
Qualtrics.SurveyEngine.setEmbeddedData("countRest", countRest);

As you can see, I am not practical with JS. Do you have any suggestion on what is wrong?
