[[Rapid Eye Movement sleep]] Behavior Disorder Screening Questionnaire (RBDSQ) is a specific questionnaire for RBD developed by Stiasny-Kolster and team <ref name=Stiasny-Kolster-RBDSQ>{{cite journal|last=Stiasny-Kolster|first=K|coauthors=Mayer G, Scha¨fer S, Mo¨ller JC, Heinzel-Gutenbrunner M, Oertel WH|title=The REM Sleep Behavior Disorder Screening Questionnaire—A New Diagnostic Instrument.|journal=Movement Disorders|year=2007|volume=22|issue=16|pages=2386–2393}}</ref>, to assess the most prominent clinical features of RBD according to the International Classification on Sleep Disorders <ref name=icsd>{{cite journal|last=Atlas Task Force of the American Sleep Disorders Association (ASDA)|title=The International Classification of Sleep Disorders— Diagnostic and Coding Manual.|journal=Minnesota: Rochester|year=2005}}</ref>. It is a 10-item, patient self-rating instrument with short questions to be answered by either 'yes' or 'no'. <ref name=Stiasny-Kolster-RBDSQ>{{cite journal|last=Stiasny-Kolster|first=K|coauthors=Mayer G, Scha¨fer S, Mo¨ller JC, Heinzel-Gutenbrunner M, Oertel WH|title=The REM Sleep Behavior Disorder Screening Questionnaire—A New Diagnostic Instrument.|journal=Movement Disorders|year=2007|volume=22|issue=16|pages=2386–2393}}</ref>. The validity of the questionnaire iswas studied by researchers and they have observed it to perform with high sensitivity and reasonable specificity in the diagnosis of RBD <ref>{{cite journal|last=Nomura|first=Takashi|coauthors=Inoue, Yuichi; Kagimura, Tatsuo; Uemura, Yusuke; Nakashima, Kenji|title=Utility of the REM sleep behavior disorder screening questionnaire (RBDSQ) in Parkinson’s disease patients|journal=Sleep Medicine|date=August 2011|volume=12|issue=7|pages=711–713|doi=10.1016/j.sleep.2011.01.015}}</ref> . Although, the performance is good, for a definitive diagnosis [[polysomnography]] is required to definitely rule out differential diagnoses such as sleep-related epileptic seizures, non-REM parasomnias (e.g., sleepwalking), obstructive sleep apnea (OSA), or nocturnal periodic leg movements (PLM)<ref name=icsd>{{cite journal|last=Atlas Task Force of the American Sleep Disorders Association (ASDA)|title=The International Classification of Sleep Disorders— Diagnostic and Coding Manual.|journal=Minnesota: Rochester|year=2005}}</ref>.

RBDSQ has the potential to be useful as a screening instrument for neurodegenerative disorder, such as the α-synucleinopathies, [[Parkinson’s disease]] or [[multiple system atrophy]] which may enable early diagnosis and also recruitment of RBD patients necessary for research studies as well as for therapeutic trials.
