Hi, all,
don't worry anymore.

I was able to reproduce.

If I initially code the second scale "A1 = in der Vergangenheit"
BUT later change my mind and set the code to "A2 = in der Vergangenheit"
I get this in my data (what is really obvious)


Typical GIGO, but not a real problem.
As you have to recode many of your scales (the ones that still have alphanumerical codes), you may recode these variables to "not empty -> 1, empty -> 2"

By the way:
Compare questions "SymptomeIntra" and "SymptomeIntraGrund"
Wenn's denn Stolperschreibweise sein soll,... 
On the other side: Of course, only males can cause changes.

I was trying to reproduce it from filling out surveys  
I would expect that a change in the answer coding is known by the survey manager.

Me, too. But the survey itself seems to be fine.

Maybe known, but not mentioned, not seen as relevant.
We had a few threads here that the survey admin changed a code during an active survey thinking that this change was reflected in all exisiting responses.

In my opinion this sudden change is comprehensible.
First it was "A1" and "A1"..
Then the idea came up that it was better / inevitable to have different codes.

Anyway, we can only guess.

Hey guys,

thanks a lot for you responses! I indeed suspected that this might be the cause but when I remember correctly, it also shows for "in der Gegenwart" A2 as answers - which was never set by default and was never changed..

However, to answer your question why I didn't know: five people (also students) in total worked on this project, so I wasn't sure if someone changed it. And even if someone indeed changed it, they'd probably not admit it (but there's ofc also the chance that I did it and don't remember).

Anyway, thanks for your help and support, really appreciate it
