First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looks at whether the size of a screen (from a smartphone to a large monitor) affects how people answer stress questions on a visual scale. Two hundred healthy adults will rate their stress on different devices and on paper. Saliva samples and heart rate measurements will also be taken. The goal is to make online surveys more reliable.
