3. Does the amount of saliva in your mouth seem to be:
0[ ]Too little
1[ ]Too much

Personnel and Training Required
The interviewer must be trained to conduct personal interviews with individuals from the general population. The interviewer must be trained and found to be competent (i.e., tested by an expert) at the completion of personal interviews.* The interviewer should be trained to prompt respondents further if a "dont know" response is provided.
*There are multiple modes to administer this question (e.g., paper-and-pencil and computer-assisted interviews).
|Specialized requirements for biospecimen collection||No|
|Average time of greater than 15 minutes in an unaffected individual||No|
Mode of Administration
Infant, Toddler, Child, Adolescent, Adult, Senior, Pregnancy
Participants ≥17 years of age. May also be asked of children under 17 years old via a proxy.
These questions are from a nationally recognized study and are predictive of decreased salivary flow.
