have a survey question that is a yes or no, and if it is a yes, then want them to add more detail. how do you do that?
From our experience there are two different options that you can use.
If the ‘more detail’ will be just a few words, you can set the SPECIAL SETTINGS under the YES option as OTHER-WRITE IN. In these cases we modify the option to read ‘Yes (please provide details):’. We also use a script available in the SurveyGizmo documentation to make the OTHER write-in box disappear unless the option is selected.
The second option is to place an ESSAY/LONG ANSWER followup question immediately below the first question. This question would ask something like “You answered that you do use X in Y situations. Can you please provide details:”. We then set a Logic Rule for this question so that it appears only when the respondents answers YES to the first question.
We use the Allow Comments option too in cases where we want respondent’s opinions – it is a useful tool. However we don’t use it often – most of our survey work is used to evaluate government programs, so our followup questions tend to be very targeted to soliciting specific information.
