Add guidance on communicating eligibility criteria

Problem

Researchers can use their own eligibility criteria that would not be capture by our system. The only things we can check for are (1) age, (2) prior participation in CHS studies, and (3) conditional statement using the set of fields that are available in the study's criteria expression (includes certain child conditions, languages, gender, age, gestational age). So when the researchers have eligibility criteria that is not captured by these things, it is up to them to make the criteria very very clear. We should provide more explicit guidance on how to do this.

Info to add to docs

if researchers have study eligibility criteria that isn’t captured by our system (via age, prior participation, and criteria expression fields), they should add a checkbox frame before the consent frame where the parent must acknowledge each item before continuing. E.g.

• My child is between the ages of 3 and 5 years old
• I am my child’s parent or another legal guardian
• We live in the United States
• My child is learning English and is not meaningfully exposed to any speech other than North American English.

Other recommendations we should mention for how researchers should communicate non-standard eligibility criteria:

• Put it in the title
• Put it in the preview summary that appears in the study ad
• Describe it in the short description and/or purpose (e.g., “Because this study is about how children learn new sounds, the only children who can participate are those who live in the United States and are being exposed only to North American English”).

Question

Does this checkbox frame go against our policy of promoting inclusivity in participation? For instance, if a family wants to do the study because it looks like fun, do we want to make them lie to get through to the next part? Maybe this checklist frame should say something like, "I understand that, in order to be eligible for inclusion/compensation, the following things must be true...*" (versus "I confirm that the following things are true...").

No file is named; start by locating the documentation on study eligibility, consent, and study descriptions. Add guidance covering checkbox acknowledgments and where to repeat non-standard criteria, then ensure the final wording reflects the resolved policy question about eligibility versus confirmation.
