I'm assuming you're talking about clinical trials- there is a website to search through all of them! Just Google clinical trials at Yale healthy volunteers (or a specific condition you are looking for) and you'll get to a website where you can filter and search through them, then email the contact listed. You won't qualify for some of them or they will be closed to new volunteers, but tell them you are interested in future studies and they will reach out when a new one pops up! Also check telephone poles and bus stops for flyers. Pfizer also does overnight studies that pay out a lot more.

What makes you a Qualifying person

I've done a number of studies with Yale. Each different study has qualifiers depending on the research. Some are very specific that you must have a particular condition. Others are looking for healthy volunteers to use as baseline. You can check the Yale website as the above commenter said. You can also check new haven craigslist. Search for "research" or "study" or look under volunteers or gigs.

It depends on the study. They're usually pretty specific, e.g., looking for diabetic men between 35 and 50 who imbibe more than two alcoholic beverages a day.

Sign up on their site. Or sign up for one of their studies and it should have an option to check off if you want to be contacted if you qualify for other ones. I've had them call/text me a couple times kn the last few months for stuff.

Apply for a study you qualify for. There’s a website.

Not sure what OP's goal is for wanting to participate in research studies, but the Yale Library also has a user research program that offers gift cards between $5 and $25 per study. The research is focused on users' experiences of library products and services- no doctor visits or medication, and most studies are done virtually.

>The factors that allow someone to participate in a clinical trial are called “inclusion criteria,” and those that prevent someone from participating are called “exclusion criteria.”

>These criteria are based on factors such as age, gender, the type and stage of a disease, previous treatment history, and other medical conditions.

>Many trials need healthy volunteers. Participants who are healthy are often needed to provide information that can be compared with people who have a particular disease.

>It is important to note that inclusion and exclusion criteria are not used to reject people personally. Instead, the criteria are used to identify appropriate participants and keep them safe. The criteria help ensure that researchers will be able to answer the questions they plan to study.

They also have a mailing list to alert you of new trials

Crystal meth most times

It seems to be all going thru the Yale New Haven patient account portal now. I got an email about signing up - “opting in” to show interest, and had to check from a long list of study type categories which ones I was interested in being approached for.

They can use your medical data to filter for candidates , but they’d still have to contact you to ask about other qualifying conditions and exclusions.

I couldn’t see a way to apply for specific studies anymore - they contact you, not the other way around.

Hi! I conduct research at Yale. Please log in to mychart and create a research profile so the recruitment team can contact you about studies you may qualify for.
