Use checkboxes or radio buttons in PDFs?

What's the difference? When to use either? PDF prep software sometimes defaults to radio buttons when checkboxes seem to be enough.

Checkboxes and radio buttons have different input rules, but they output the same. The difference impacts the choice of questions types to collect an input, although I would always choose a checkbox field type when prepping a PDF.

Both checkboxes and radio buttons both output boolean values for their respective choices. Both present a list of options each of which option is either selected or not selected, true or false. The difference is that radio button questions allow only one of the booleans to be true, while checkbox questions allow any and all booleans to be true. The difference consists of the question input rules, not the output values.

The limitation of the input rule makes sense. Often checkboxes appear on forms as Yes/No options to a question. The radio button input rule is appropriate if the yes and no options present mutually exclusive, exhaustive answers to the questions.

Using checkboxes instead of radio buttons in the PDF makes it easier to send the output from radio buttons from the guided interviews to the checkboxes on the form. Radio buttons at the PDF level add an superfluous layer of logic. Checkboxes can "catch" radio button outputs without the added layer of encoding the logical relation between the outputs on the template level. The question type already encodes the logical relation by constraining the input.

  • Is this technically true? I know it seems vaguely true to me.
  • How do the guided interview platforms actually compare on the technical implementations of checkboxes and radio buttons?
  • How do the guided interview platforms connect to PDF outputs of type radio button?
  • Is it really a problem for document automation to implement radio buttons at the form level instead of the question level?
