You can make contact information (Name, Phone, or Email) or any Single Line question required in your screener so that respondents must answer them before advancing or submitting the page (works on intercepts and links). Required questions are marked with a red asterisk (*) on both the screener and the Ethnio editing interface.
Note that the email validation checks to make sure the email is valid, but name and phone only require characters to be present. You can toggle required questions on from inside the Name, Phone, or email questions types in screeners >> questions:
Keep in mind, we are working on adding more types of questions to be required. For scheduling, if you do not require email or name in your screener, you may get responses that cannot be scheduled—this is because we have no way to contact them.
Custom Alert Language
No matter which required fields you decide to use, there is a small customizable message that appears for one or more blank required fields in a screener (intercept or link). On the screeners >> questions page, look for the "customize alert language" button at right:
You can edit this language, which is saved per screener, on the screeners >> questions page on the right side:
Two Quick Gotchas
Important Note on Long Screeners
Put required fields at the bottom of any long screener page, or keep the page short.
There are certain scenarios where your respondents may run into some confusion around required questions. The most important to be aware of is do not place required questions at the top of a very long single page. This might result in the intercept or screener link being scrolled down so far that your respondent can't see the required field warnings. In other words, keep required questions on as short a page as possible or at the bottom of the page near the submit/next button.
Careful with Drill Down Questions
Don't put required fields in drill down questions unless you absolutely have to.
You can place a required question inside of a drill down, but Ethnio will not force your respondents to answer it, unless they correctly answer the drill down. In other words, if you drill down on location, but only show required email to certain respondents:
Then if your respondent doesn't ever see the email field, we will allow them to continue without the required field. That is because they have absolutely no way of knowing there's a required field in the drill down:
