Ethica allows screening potential participants in your study against certain inclusion or exclusion criteria, and only allows those to join your study who meet the criteria. This is achievable by creating an Eligibility Survey for your study, adding the necessary questions, and then defining a criteria based on these questions. In this section, we explain how this can be done in Ethica.
You can screen your participants for eligibility by creating an Eligibility Survey. Such a survey is asked from prospective participants just before joining your study. Based on their responses, a participant might be eligible to join or not.
To add an Eligibility Survey to your study, start by navigating to the Researcher Dashboard and clicking on
Activitiesfrom the left-side menu. On the Activities page, click on the
Newbutton. This will create a new survey activity with the default settings. In the
Contentsection of your new survey, add the questions you want to ask participants when they're trying to join your study.
After adding the questions, switch to the
Triggering Logicsand click on the
Eligibilityfrom the list of triggering logic types. Considering the questions you added, enter valid Eligibility Criteria. These criteria determine under what conditions a participant is considered eligible and allowed to proceed and respond to the study, and which responses can mark the participant as ineligible.
Then, move to the
Preview and Publishtab. In there, click on the
Publishtab from the left-side panel. Enter a Version Note as necessary, and then click on the
Publishbutton to publish your survey.
After publishing your eligibility survey, any participant trying to register in your study first will be presented with this survey. If the participant cancels the survey, they are considered ineligible and are not allowed to proceed. If they complete the survey, upon completion, Ethica evaluates their responses and depending on the results, either allows the participant to proceed with the registration, or informs them that they are ineligible.
Note that there is no limit on the number of times a prospective participant can respond to the eligibility survey. If they are marked as ineligible on their first try, they can try it again and respond to the eligibility survey for the second time.
Ethica records all responses given to your eligibility survey. You can access these responses by going to the
Survey Responsespage. Then, select the survey from the list of available surveys and check the
All Participantsoption and click on the
Displaybutton. You'll see answers separated by participants and questions.
