The REM Sleep Behavior Disorder Screening Questionnaire (RBDSQ) is a specific questionnaire for
rapid eye movement behavior disorder (RBD) developed by Stiasny-Kolster and team,
to assess the most prominent clinical features of RBD.
It is a 10-item, patient self-rating instrument with short questions to be answered by either 'yes' or 'no'.
The validity of the questionnaire was studied by researchers and they have observed it to perform with high sensitivity and reasonable specificity in the diagnosis of RBD.
Use
RBDSQ has the potential to be useful as a screening instrument for
neurodegenerative disorder
A neurodegenerative disease is caused by the progressive loss of neurons, in the process known as neurodegeneration. Neuronal damage may also ultimately result in their death. Neurodegenerative diseases include amyotrophic lateral sclerosis, mul ...

which may enable early diagnosis and also recruitment of people with RBD necessary for research studies.
Format
RBDSQ contains a set of 10 items that are to be answered by either 'yes' or 'no'. Items 1 to 4 address the frequency and content of dreams and their relationship to nocturnal movements and behavior. Item 5 asks about self-injuries and injuries of the
bed partner. Item 6 consists of four subitems assessing nocturnal motor behavior more specifically, e.g., questions
about nocturnal vocalization, sudden limb movements, complex movements, or bedding items that fell down. Items 7 and 8 deal with nocturnal awakenings. Item 9 focuses on disturbed sleep in general and item 10 on the presence of any neurological disorder. The maximum total score of the RBDSQ is 13 points.
