Summary

This study aims to translate and validate a French version of the Sleep Regularity Questionnaire (SRQ), a tool that measures how consistent a person's sleep schedule is. Researchers will enroll 50 adults with chronic insomnia or circadian rhythm disorders, who will fill out the questionnaire twice over 14 days. The goal is to ensure the French version is accurate and reliable, so it can be used in clinics and research to improve sleep health.

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 provide a reliable French-language tool to measure sleep regularity, helping doctors and researchers better understand and address sleep health issues.
What could go wrong
This is a small, early-stage validation study (50 participants) focused on translation and measurement accuracy, not a treatment trial. The questionnaire may not capture all aspects of sleep health or may not work well in broader populations.
