The GSDS-T was developed by Lee KA to assess difficulty falling asleep, waking up during sleep, sleep quality, and daytime alertnes. The Turkish validity and reliability of the scale has been conducted on stroke patients but not on multiple sclerosis patients. The aim of this study is to investigate the validity and reliability of the Turkish version of general sleep disturbance scale (GSDS-T) in patients with multiple sclerosis. GSD has 21 questions. This study will be conducted on patients with multiple sclerosis (MS). 126 participants will be included in the study. In order to evaluate the validity of the GSDS-T, the Pittsburgh Sleep Quality Index (PSQI) which can evaluate sleep quality and has been validated in Turkish, will be used. Scales will be repeated after 15 days to assess test-retest reliability.
