Classification
Supplemental: Parkinson's Disease (PD)
Short Description of Instrument
Mayo Sleep Questionnaire (MSQ) consists of 16 items designed to screen for the presence of a wide range of sleep disorders (e.g., RBD, PLMS, RLS). MSQ is designed to be completed by caregivers/bed partners.
 
The presence of RBD is assessed by a single question focusing on recurrent dream enactment behavior: "Have you ever seen the patient appear to 'act out his/her dream' while sleeping (punched or flailed arms in the air, shouted or screamed)?" Five additional questions are subsequently asked when the initial response is positive.
Comments/Special Instructions
MSQ is a simple instrument with high sensitivity. Nonetheless, a practical constraint is the need for input from the bed partner, which may not be always available especially for those aged patients.
Scoring and Psychometric Properties
Psychometric Properties: Among cognitively impaired participants, the single core MSQ question on RBD showed a sensitivity of 98% and specificity of 74%. Among community-dwelling elderly the sensitivity is 100% and specificity 95%.
Rationale/Justification
Strengths: High specificity
 
Weaknesses: Requires presence of the bed partner
