title: Drooling quantification: Correlation of different techniques.
abstract: OBJECTIVE
  The aim of this study is to evaluate the correlation of the Drooling Quotient (DQ) score with the questionnaire-based Drooling Severity and Frequency Scale (DSFS) and the number of bib changes in a day. It is hypothesized that there is a significant positive correlation between these methods of assessment.
  
  
  METHODS
  Using a prospectively collected database from a cohort of one hundred and fifty five children referred to our saliva management clinic, a comparison of the following three measurements was made to assess the level of correlation between them: (1) Drooling Quotient (DQ) (performed in two 10-min sessions), (2) Drooling Severity and Frequency Scale (DSFS) (as judged by parents or caregivers) (3) number of bib changes (as reported by parents or caregivers).
  
  
  RESULTS
  The results showed that there is a high level of agreement between the Drooling Quotient and the Drooling Severity and Frequency Scale. However, the Drooling Quotient and number of bib changes did not show significant correlation.
  
  
  CONCLUSIONS
  The Drooling Severity and Frequency Scale (DSFS) has been shown to be a quick and accurate measure of drooling that can be used to help guide clinical management of drooling, particularly in patients who are unable to undergo the Drooling Quotient assessment.
