ClinConnect Summary

This clinical trial is studying a tool called the General Sleep Disturbance Scale (GSDS-T) which helps to measure sleep problems in people with Multiple Sclerosis (MS). The researchers want to see if this Turkish version of the scale is reliable and valid, meaning it accurately measures sleep disturbances for Turkish-speaking MS patients. This is important because while the scale has been tested in other patient groups, it hasn’t been specifically tested in those with MS yet.

To be eligible for this study, participants must be at least 18 years old, have been diagnosed with MS for at least two years, and have a specific level of disability (measured by something called the EDSS score) greater than 2. They should not have insomnia or severe symptoms that affect their ability to participate. Participants can expect to fill out questionnaires about their sleep habits and may contribute to important research that could help improve understanding of sleep issues in MS. The study is currently not recruiting participants, but it aims to gather valuable information that can lead to better sleep assessments for those living with this condition.
