Hi, Ana,
here is an example how I would do it.
I splitted the nivSSP-question into several parts according to the main categories.
Like this:
I used subquestion relevance to display the subquestions.
This is much better.
Of course you may split more, e.g.
"2. Specific complaints and symptoms" into 2.1 - 2.4. and 2.5. - 2.9
So you have 48 and 49 subquestions instead of 97.
I used this special way to code to ease the relevance equation.
Now it's only
count(that.sq_A1.NAOK)>0
count(that.sq_A2.NAOK)>0
...
If you split the second main category, this equation have to be
count(that.sq_A21.NAOK,that.sq_A22.NAOK,that.sq_A23.NAOK,that.sq_A24.NAOK)>0
count(that.sq_A25.NAOK,that.sq_A26.NAOK,that.sq_A27.NAOK,that.sq_A28.NAOK,that.sq_A29.NAOK)>0
As I used EXCEL to quickly create the codes, the items and the subquestion relevance condition, you may change the text of the symptoms.
Furthermore here is a nice way to display your 2-level SSP question.
It automatically removes checks in subcategories if the main category is unchecked.
And here the sample file
