Attention: [age] year old [gender] resident
Dear Resident:
Recently, a Field Interviewer from Research Triangle Institute came to your home and asked you to participate in the
National Survey on Drug Use and Health. At the time, you expressed some reluctance about spending the time necessary
to do the interview.
A limited number of people were randomly selected to represent the population of the U.S. You cannot be replaced. If you
choose not to participate, your experiences and views—as well as the thousands of people you represent—will not be
heard.
As you know, this nation is made up of all kinds of people, and so we are interviewing all kinds of people—including busy
people like you. If we only interviewed people who have a lot of free time, then active people like yourself would not be
fairly represented. Your participation is critical to the success of this study, and we are happy to make a special effort to
work around your schedule so that you can be included.
We appreciate that your time is a precious commodity. As a token of our appreciation, you will receive a cash payment
of $30 at the end of the interview.
We combine your answers with the answers of thousands of other people and report them only as overall numbers. The
survey is set up so that you record most of your own answers—the interviewer never sees or hears them. Also, the option
to refuse to answer any question is always available.
The results of this study help state and national policymakers learn about health issues—including information on alcohol,
tobacco, and drug use, non-use, and opinions—so that informed decisions about policies and programs can be made. By
participating in this study, you will make a direct impact on important health-related decisions.
Thank you for your time. I hope you’ll reconsider and choose to participate in this extremely beneficial study.
Sincerely,
[FS NAME], Field Supervisor
P.S. Please, if you have any questions or would like to set up an appointment, telephone me toll-free at [TOLL FREE

Dear Resident,
Recently, a Field Interviewer from Research Triangle Institute came to your home and asked you to participate in
the National Survey on Drug Use and Health. At the time, you were not interested in participating. We are writing
this letter to ask you to reconsider.
The results of this study help state and national policymakers learn about health issues—including information on
alcohol, tobacco, and drug use, non-use, and opinions—so that informed decisions about policies and programs can
be made. By participating in this study, you will make a direct impact on important health-related decisions.
Without adequate levels of participation, these health-related decisions might not be as informed, and money for
programs that might be needed in your state or community could be directed elsewhere.
A limited number of people were randomly selected to represent the population of the U.S.—and you were one of
them! You cannot be replaced. If you choose not to participate, your experiences and views—as well as the
thousands of people you represent—will not be heard.
We appreciate that your time is a precious commodity. As a token of our appreciation, you will receive a cash

Attention: Parent/Guardian of [age] year old [gender] resident
Dear Resident,
Recently, a Field Interviewer from Research Triangle Institute asked permission for a young person in your home
to participate in the National Survey on Drug Use and Health. At the time, you expressed some reluctance about
exposing your teen to questions related to substance use.
We understand your concern. Please know that if you allow your teen to participate, the option is always available
for him or her to answer “I don’t know” to any question.
The survey also includes other questions related to school and community topics, such as participation in different
types of school-based activities.
A limited number of teens were randomly selected to represent the teenage population of the U.S. Your teenager
cannot be replaced. We need responses from everyone selected to get an accurate picture of teenage health issues.
For example, in order to know how many teens are using various substances, we need to hear from the thousands
of teens who are not using any substances.
We also appreciate that your teen’s time is a precious commodity. As a token of our appreciation, your teen
will receive a cash payment of $30 at the end of the interview. Also, the interviewer can give your teen a
Certificate of Participation—some participants have been able to go to their schools with this certificate and get
class or community service credit for participating in the survey.
Thank you for your time. I hope you’ll reconsider and choose to let your teenager participate in this extremely
important and beneficial study.

refuse any question.
We understand that the privacy of your family is important—Research Triangle Institute protects participants’
