Hello,

In my survey, I have included a third alternative in the DCE which acts as an opt-out. Should participants choose this alternative/the opt-out, I would like to follow up with a question on the same choice task which forces participants to make a choice i.e. “What would you pick if you had to select between A or B?”

I was wondering if I can program this forced choice task in the software ,and, if so, how.

Thank you,  
Sinead

Hi there,  
There is a good tutorial on this here.  
[https://v4-4-6.saas-de1.surveyengine.com/ssgq68e9i5tkh8k5nhj2k82di5afea8pem50gnlh6gqmcvaanu34toe46vmje0vo?preview=true&working=1](https://v4-4-6.saas-de1.surveyengine.com/ssgq68e9i5tkh8k5nhj2k82di5afea8pem50gnlh6gqmcvaanu34toe46vmje0vo?preview=true&working=1)

The trick is to capture the response and then show a parallel forced choice experiment if they opt out.

Its also on the tutorials.

Hi benno,

I have checked the optout tutorial and have a question.

In the espression “SE\_experiment\_data\_by\_design\_row(optout, 1, pref1)”, we need to specify the design row which is 1 here to duplicatet the same design row to respondents in the follow-up forced task.

But it will only show the specific designs to all respondents by doing this way. I am wondering if we can still introduce the randomly selected design row to respondents and retrive this design for respondents in the follow-up forced choice task?

Thank you,  
Yikang

Easiest way to do this is make them sequential (1,2,3) in the experiment then randomise the pages. Top right on the page editor.
