Short Description of Instrument

The Drooling Rating Scale (DRS) was first developed to evaluate sialorrhea in Parkinsons Disease Patients. The scale was a component of a speech and language therapy intervention programme developed by Marks and colleagues (2001) Simular to the Drooling Severity and Frequency Scale (DSFS) the DRS evaluates drooling in multiple situations including while sitting, standing, while in bed, talking, and eating and drinking.


The DRS consists of 5 items (Excessive dryness of mouth (Score = 0), No excess saliva (Score = 0), Excess of saliva in mouth without drooling (Score = 1), Mild to moderate drooling, needs occasional wiping (Score = 2), Continuous drooling, wet clothes or constant use of hankerchief or tissue (Score = 3)) that are scored on a scale of 0–3 with 0 indicating no drooling and 3 indicating severe drooling. The total maximum score is 15 (Marks, Turner et al. 2001, Evatt, Chaudhuri et al. 2009).
