Multiple choice form to inline script

Comments

  I'd like to provide a bit more context to my question.

  The question in the survey is:

  What educational titles do you have?

  And hypothetical answer options are:

  • Level 1
  • Level 2
  • Other

  Respondents can select multiple educational levels. The problem is, once they select "Other" I want them to also fill in what other educational level they may have.

  
  

  To do so, I should use in-line script for the multiple choice form.

  
  

  If I use inline script, I don't know how to script a multiple choice question (the issue is this line: set allow_multiple "yes")...

  
  

  If I use multiple choice preset form, I don't know how to set the condition in "Run if" for the form corresponding to filling in "other" because it is a multiple choice form. So, if a person ONLY selects "other", then it is easy to fill in the "run if" command ([educ]='Other' works fine). But, if a person specifies both "Level 1" and "Other" then it becomes more complicated, as there are multiple combinations of possibly selected answers...

  
  

  So, I think the "easiest" way to do this, is to use an inline script. But I am still left with the question of how to "make" a multiple choice question in an inline script...

  
  

  Any ideas are much appreciated.

  
  

  I attach a small experiment to illustrate my challenge.

  Hi Paula,

  
  

  Thanks for the additional info!

  I think it's easiest to use a Run-if statement. Because, as you said, participants could check multiple boxes, you could add a bit of Python code in an inline_script item to determine whether or not to run the additional question. You could put something like the following in its Run tab:

  
  

  var.run_additional_question = "no"
  
  if "Other" in var.educ:
      var.run_additional_question = "yes"
  

  
  

  Make sure to:

  • Use the square-bracket method for the Run-if statement in the tab of your trial_sequence:

  [run_additional_question] = "yes"
  

  • Put the Python code in the Run phase and place the inline_script item after the first question but before the additional question

  I attached an example experiment.

  
  

  Hope this helps!

  
  

  Cheers,

  Hi! I have an additional question :) What if I also want to add a form validator (forced response) to this question?

  I know I need to add this code to an inline script:

  while True:
  	incomplete = False
  	items.execute("form_multiple_choice")
  	if None in [var.educ]:
  		incomplete = True
  	if not incomplete:
  			break
  	else:
  		items.execute("warning_message")
  

  
  

  However, I am having trouble in the following line, as it seems OS simply ignores it and the warning message is never displayed:

             if None in [var.educ]:

  It seems to be working by changing " None " to " u'no' " in this way:

  if u'no' in [var.educ]:

  Hi @Paula ,

  
  

  If you don't make a choice after a form_multiple_choice item, the response variable is indeed set to "no". Well done for finding this out! :)

  
  

  In the future, printing variables to the console could be helpful:

  print(var.educ)
  

  
  

  Or is this exactly what you did?

  
  

  Cheers,

  Thank you for the tip on print(var)!

  I figured it out because the OS documentation mentions that for some forms (ratingscales vs checkboxes), the default is 'None' and for others it is 'no'. I tried both to see which one works, taking a low-tech approach :-) The documentation is quite complete and that helps a lot!
