Short Description of Instrument
The Swallowing Disturbance Questionnaire (SDQ) is a 15-item scale that assesses swallowing in Parkinsons Disease and dysphagia.
 
It was originally developed as part of a study examining correlations between objective measures of dysphagia and symptoms of dysphagia.
Scoring
Each question is scored on a 4-point categorical scale (0–4) with 0 meaning “Never” and 4 meaning “Very Frequently. More than 7 times a week.”
