Phone vs. desktop: does screen size skew stress surveys?
NCT ID NCT04040608
First seen Feb 19, 2026 · Last updated Jun 21, 2026 · Updated 21 times
Summary
This study is testing whether the size of a screen (from a smartphone to a large monitor) affects how people answer stress-related questions on a visual scale. Researchers will ask 200 adults to rate their stress on different devices and on paper, and also measure saliva and heart rate. The goal is to see if online surveys give consistent results across devices, which could improve how stress is measured in future research.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could help researchers design better online surveys that give consistent results regardless of the device used.
What could go wrong
This is a small, early-stage observational study with no treatment. It only looks at how people answer questions on different screens, so it won't directly improve health or stress.
