Questionnaire Design Research Laboratory

Information for Selected Respondents


Thank you for agreeing to participate in our study. We reserved an appointment time specifically for you. Please plan to arrive at least 5 minutes before your scheduled appointment. If you are running late for your appointment, please call 301-458-4676. 

Once you come into our building, you will be required to walk through a metal detector and your bags will be screened by an x-ray machine. You will be required to show valid government-issued photograph identification, such as a driver's license or passport. After screening is completed, tell the security guard that you are here to visit Lauren Creamer. You will then need to sign-in on our Questionnaire Design Research Laboratory (QDRL) visitor list. Then the guard will issue you a QDRL visitor's pass. We will come down to the lobby to greet you & will take you upstairs for the interview.

For more information please contact Lauren Creamer at
