Effects of different screen sizes on stress measurement
Influence of Screen Sizes on Responses to Visual Analog Scales of Stress
University Hospital, Clermont-Ferrand · NCT04040608
This study tests how different screen sizes affect people's stress levels as measured by a simple scale and looks at how these responses change over a week.

What this trial studies
This observational study investigates how varying screen sizes affect responses to visual analog scales (VAS) used for measuring stress. Participants will complete the same VAS on four different screen types (24-inch screen, laptop, tablet, smartphone) and on paper, with saliva samples collected for biomarker analysis. The study also aims to assess the variability of responses over a week and explore the relationship between work perception, work addiction, and stress biomarkers. The goal is to better understand the impact of digital interfaces on stress assessment.
Who should consider this trial
Good fit: Ideal candidates for this study are adult individuals who can understand and respond to basic questions.
Not a fit: Patients with cognitive disorders or those who refuse to participate may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could improve the accuracy of stress assessments conducted via digital platforms.
How similar studies have performed: This approach is novel, as the influence of screen sizes on VAS responses has not been previously studied.
