Forms: Rating Scale: Data Logging with Loop

Dear beautiful people. As of now, I'm not particularly savvy with OS, but I'm trying to learn :) Here's the situation. I want to implement a couple questionnaires to present during my experiment. One is a mood scale, where participants mark how strongly they feel a certain mood at the moment. It's 24 items, so I thought it might be a good idea to use a Loop instead of hard-coding each item.

Furthermore, I don't want to present all of the items on the same page (I think three items per page might be a good measure). So what I did was coding a questionnaire page with three items on it which refers to question texts and variables in the loop.

set timeout infinite
set spacing 10
set rows "1;1;1;1;1"
set only_render no
set margins "50;50;50;50"
set description "A generic form plug-in"
set cols "1;1"
set _theme gray
widget 0 0 2 1 label text="Im Moment fühle ich mich"
widget 0 1 1 1 label center=no text="[question_text_1]"
widget 1 1 1 1 rating_scale nodes="überhaupt nicht;;;;sehr" var="[var_mdbf_t1_1]"
widget 0 2 1 1 label center=no text="[question_text_2]"
widget 1 2 1 1 rating_scale nodes="überhaupt nicht;;;;sehr" var="[var_mdbf_t1_2]"
widget 0 3 1 1 label center=no text="[question_text_3]"
widget 1 3 1 1 rating_scale nodes="überhaupt nicht;;;;sehr" var="[var_mdbf_t1_3]"
widget 0 4 2 1 button text=Weiter

Presenting the questions works fine, but the data logging is a complete mess. I think it's to do with my loop table, I think I'm misunderstanding the variable generation. I want every item to have its own column in the output where I have the answer the participant gave (0 to 4). Instead, I get one column each for var_mdbf_t1_1 through 3, and in there the variable names I want to give the individual items, based on the loop. The loop table looks like this:

I'm not sure if I'm making myself clear. The idea is, that in the end, each item has a column in the log file, and in this column a value indicating which choice the participant made.

Thank you so much for reading, this community is amazing. Have wonderful holidays, everyone!
Cheers, Vincent

    Hi Vincent,

    Would you mind uploading your experiment? Maybe even one logfile.

    But from the way you describe it, you won't be able to get one column per item. It's a trade off between using loops efficiently and having separate columns. Probably it is your call on what is important to you.

  • Hi Eduard,
    thanks for the quick reply, I'll attach the experiment and a test log. The break screen in the middle requires a space keypress.
    Best and happy holidays to you!

    Hi Vincent,

    As I said, you either have to go for a form item with only a single question but the same variable name. This will give you a single column with all the responses. Or you can go for as many questions as you like per page and each question has a difference variable name. Like that you would end up with as many columns as you have questions, with each response being in a separate row.

    Does that make sense?
