Confidentiality When You Cannot See the Room

Part of Decentralized Trials (DCT) Training: Verifying Who You Are Talking To.

About 2 minutes. Free, in your language, no account needed.

The screen shows you a fraction of the space

Somebody can be sitting three feet outside the frame. A smart speaker can be listening. A housemate can walk in.

You cannot control this, and you can ask about it and record the answer.

Ask at the start

"Is there anyone else with you, and are you somewhere you can speak privately?"

Asked plainly, at the beginning, it is normal and it gives the participant permission to move or reschedule.

Respect the answer

If they say a family member is present and they are comfortable, that is their choice and it goes in the record.

If they say they are not private and would rather continue anyway, consider what the visit involves. Symptom reporting and mental health assessments are the ones where privacy changes the data.

Your side of the call matters too

An open-plan office, a colleague within earshot, a screen visible from a corridor. The participant cannot see your room either.

Use a private space, use headphones, and lock your screen when you step away.

Recording is a decision, not a default

If the platform can record, know whether this study permits it, whether the participant consented specifically to it, and where the recording is stored and for how long.

A recording made without a basis is a personal data problem that lasts as long as the file does.

Do not use personal channels

A message from your own phone, a personal email address, a consumer messaging app. They feel helpful and they move participant data outside every control the study has.

Use the study's channels even when they are slower.

Write down what affected the visit

If the participant was not private, or somebody else was present, that belongs in the record because it may explain a reported outcome later.
