RTI International interviewers are going door-to-door in Delaware conducting a study called the National Survey on Drug Use and Health on behalf of the Substance Abuse and Mental Health Services Administration, an agency in the U.S. Department of Health and Human Services.

The annual study is a scientific, national survey that provides up-to-date state and national information on alcohol, tobacco or drug use, mental health and other health-related issues. Delawareans who are asked to do in-person surveys should have received a letter ahead of time from DHSS.

Interviewers who come to the door will have a photo ID that identifies them as working for RTI International and on behalf of DHSS. The interviewer will start with a few general questions, and then may ask for one or two members of the household to complete an hour-long interview. The extended interviews do not need to be conducted in the home. The interviewer might suggest a nearby library or another public place.

Participants do not need to know anything about alcohol, tobacco or drug use to answer the survey questions, and interviews from people who do not use these substances are just as important to the study as interviews from people who do use these substances. The names and addresses of participants will not be connected to their answers, and answers are kept confidential. People who complete the hour-long interview will receive $30 in cash.

RTI International, a nonprofit contract research organization from North Carolina, is conducting the survey as a contractor for the U.S. Department of Health and Human Services. Field interviewers in Delaware are Cynthia Jakacki-Null, Linda McGoy, Claudia Dandridge, Nancy Lopez, Evelyn Crespo Morales, Jan Schafer, Luis Buitrago, Teresa Gray, Jennifer Ames, Karen Cunningham and Kathleen Dondarski.
