Participants · Checklist
Compare the practical requirements
Bring time, travel, visits, and unanswered questions into one view. A comparison can organize information without ranking studies for you.
Editorially reviewed
Two listings can look similar at first glance and ask quite different things of participants. A side-by-side view can help you notice those differences and identify the questions to take to each study team.
Begin with the same questions
Compare like with like: the total duration, number of visits, expected travel, activities at home, and information about costs or reimbursement. If one listing is less detailed, treat that as a question to resolve, not as evidence that participation would be simpler.
The Solvidence planner compares up to three listings at a time. It presents published details; it does not recommend a study or assess your eligibility.
Look beyond the visit count
A count of visits does not describe the entire commitment. A short visit far from home may require a different arrangement from a longer visit nearby. Tasks between visits may also take time.
- Ask about the expected length of each visit.
- Clarify which activities take place at home and how often.
- Check whether the schedule is fixed or whether any flexibility is available.
- Ask what happens if you need to change an arrangement.
Keep unknowns visible
Write down what the listing does not tell you. For example, a location may be named without parking details, or reimbursement may be mentioned without explaining its conditions.
Do not infer these details from a photograph, a nearby office, or another study. Use the reference number when asking the team about the exact listing you are considering.
Use the comparison as a conversation aid
The differences view can reduce repetition. Return to the full comparison before drawing conclusions: identical wording does not mean that every part of two studies is the same.
A printed comparison can be useful during a discussion. Check the current listings and their review dates before relying on an older copy. Share the public comparison link when you want someone to see the same selected listings; it does not share your saved list or private questions.
Keep the decision in context
Convenience is only one part of considering research. Questions about the research procedures, uncertainties, and possible effects on your health belong in a discussion with the study team and your own clinician.
You can organize the information without making a decision that day.
Take it into a conversation
Questions worth asking.
- How much time would visits and activities at home require?
- Where would visits take place, and what follow-up would be needed?
- Which costs would I be responsible for, and is any reimbursement available?
- What is already known, and what remains uncertain?
This resource helps you prepare a conversation. It does not assess eligibility, offer medical advice, or confirm a study’s availability. The study team can explain what applies to a particular study.
