Hi!

I'm trying to create a questionnaire. This works so far. Furthermore I wanted to have "tailored" answers depending on the participants choises of answering (the answer options are a matrix: 5=very true until 0=absolutely not true. And the tailored answer will refer to the participant's global result). This works as well. But there is a small problem: the answers of some questions should be count in the opposite way or be recoded before counting to the global result. e.g. I have 15 questions and question 3, 5 and 12 is poled vice versa. Meaning that at these three questions "5" means "0"; "4" means "2"; ... ; "0" means "5".

So, is there any way to get this recoding? And how?

I was trying and searching for quite a time and I could imagine that one possibility is to make each question as a questiongroup, so each question(group) can be coded unique. But I don't find this a "nice" option.

(I'm using the latest version of limesurvey.)

Thanks,
ang

Use an equation question to compute the score...

For example if:
  • QQ is the code of your array question
  • sq1 & sq2 the codes of your "normal" scored subquestions
  • sq3 & sq4 the codes of your reverse-scored subquestions
Your equation will be something like:
{sum(QQ_sq1.value,QQ_sq2.value,(5-QQ_sq3.value),(5-QQ_sq4.value))}
.

That's great! Thanks!

There is only one thing left: now the sum-score is displayed at the question which is scored vice versa. Allways changing correcty when answering. But the participant shouldn't see the score...

Do you know if there is something to not have the score seen?

Thanks!

"Hide this question" in the advanced settings of the equation question...
Note that you can place this question where you wan't in your survey, at the end for example, included in a different group (if relevant)...
