German translation, cultural adaptation for Austria, and validation of the Neurological Sleep Index-Multiple Sclerosis.

ABSTRACT:

Study objectives

To translate, culturally adapt, and validate the Neurological Sleep Index-Multiple Sclerosis (NSI-MS) for use in Austrian German-speaking populations with multiple sclerosis.

Methods

Following established guidelines, the NSI-MS diurnal sleepiness, nonrestorative nocturnal sleep, and fragmented nocturnal sleep scales underwent forward-backward translation, with content and face validity, and cultural adaptation to Austria established. Construct validity was evaluated using Rasch analysis. Known-groups validity was examined, and comparisons were made with scales measuring multiple sclerosis fatigue, daytime sleepiness, sleep quality, anxiety, and depression. Reliability was assessed through Cronbach's alpha, Person Separation Index, Lin's concordance correlati
