Dear Resident:
Recently, a professional interviewer from RTI International attempted to contact your household about
participating in the National Survey on Drug Use and Health*. So far, we have been unable to speak
with anyone in your household. Your participation in this study is important—this is why we continue to
try and reach you.
Some people are cautious about speaking to a stranger at the door, and that is understandable. Please
know that we are not soliciting or selling anything—we have just a few general questions to ask that will
take about five minutes.
It is not necessary for you to let the interviewer into your home—you can answer the questions right at
your door.
After these initial questions, someone in your household may or may not be randomly selected to
participate in the full interview. If anyone is selected for the full interview, that person will receive
$30 in cash at the end of the interview as a token of appreciation.
A limited number of households were randomly selected to represent the population of the U.S. Your
household cannot be replaced. If you choose not to participate, your experiences and views—as well as
the thousands of people you represent—will not have a chance to be heard.
Thank you for your time. I hope you’ll choose to participate in this extremely important and beneficial
study.
Sincerely,

[FS NAME], Field Supervisor

P.S. Please, if you have any questions or would like to set up an appointment, contact me toll-free at
[TOLL FREE NUMBER].

Attention: [age] year old [gender] resident

Dear Resident:
Recently, a professional interviewer from RTI International came to your home and asked you to
participate in the National Survey on Drug Use and Health*. You were not available to complete the
interview at that time and have been away or unavailable each time the interviewer has returned since
then. Your participation in this study is important—this is why we continue to try and reach you.
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.
Your answers are combined with the answers of thousands of other people and reported only as overall
numbers. To further protect your privacy, the study 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.
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. Please feel free to call me to set up an
appointment time—the interview can also be conducted at a neutral location such as a public library.
We appreciate that your time is precious. As a token of our appreciation, you will receive $30 in cash
at the end of the interview.
Thank you for your time. I hope you’ll choose to participate in this extremely important and beneficial
study.
Sincerely,
[FS NAME], Field Supervisor

List of Enclosures
2019 National Survey on Drug Use and Health

A. Lead Letter
Prior to the interviewer’s arrival at a household, a “lead letter” will be mailed to the selected address briefly
explaining the survey and requesting the residents’ assistance. The interviewer will visit the household a few days later, refer
the resident to this letter, and answer questions if necessary. If the resident has no knowledge of the lead letter, the
interviewer will provide another copy. All NSDUH interviewers prominently display their ID badge, which is referenced on
this letter.

B. Authorization Letter
Each NSDUH interviewer will carry a personal identification letter which is provided by the Substance Abuse and
Mental Health Services Administration (SAMHSA), the agency within the U.S Department of Health and Human Services
(DHHS) that sponsors the study. This letter serves as documentation that SAMHSA formally authorizes the interviewer to
work on the NSDUH for RTI International.

C. Study Description
When an in-person contact is made with an adult member of a selected household and an introductory exchange is
completed, the interviewer will follow consent procedures that include presenting a “Study Description” and answering any
questions the respondent might have. Upon respondent permission, the interviewer will proceed to create a list of all
members of the household using a tablet computer. This list includes information such as the member’s age, gender, and race,
but does not include names or any other personally identifying information. The tablet will process this roster of the
household members and apply a statistical algorithm to randomly select zero, one, or two persons age 12 and older to be
interviewed. The selected respondent(s) will be asked to complete an interview using a laptop computer.

D. Question and Answer Brochure
Entitled “Answers to your questions,” the NSDUH Question and Answer Brochure provides a ready reference to the
study, including answers to commonly asked questions. This brochure is given to each adult interview respondent or parent
or guardian of youth respondents.

E. Highlights from the 2017 Study
Each year SAMHSA releases results of the study, and this document highlights some of the findings from the 2017
NSDUH.

Attention: [age] year old [gender] resident

Dear Resident:
Recently, a professional interviewer from RTI International 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 precious. As a token of our appreciation, you will receive $30 in cash
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 interview 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 informed decisions about
policies and programs can be made. By participating in this study, you will have 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.

Attention: [age] year old [gender] resident

Dear Resident,
Recently, a professional interviewer from RTI International came to your home and asked you to
participate in the National Survey on Drug Use and Health*. At the time, you expressed some concerns
about the study.
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.
Your answers are combined with the answers of thousands of other people and reported only as overall
numbers. To further protect your privacy, the interview 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 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.
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 precious. As a token of our appreciation, you will receive $30 in cash
at the end of the interview.
Thank you for your time. I hope you’ll reconsider and choose to participate in this extremely important
and beneficial study.

Sincerely,

Dear Resident,
Recently, a professional interviewer from RTI International 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 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 sufficiently
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 precious. As a token of our appreciation, you will receive $30 in cash

Dear Resident,
Recently, a professional interviewer from RTI International 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 teenagers were randomly selected to represent the teenage population of the U.S.
You cannot be replaced. If you choose not to participate, your experiences and views—as well as a
thousand other teenagers you represent—will not be heard.
We understand that you have many demands on your time. However, if we only interviewed teenagers
who had lots of free time, then active teenagers 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 precious to you. As a token of our appreciation, you will receive $30 in
cash at the end of the interview.
Please know that your privacy will be protected. Your answers cannot be viewed by anyone—including
your parents. We combine your answers with the answers of thousands of other teenagers and report them
only as overall numbers. Also, the interview is set up so that you record most of your own answers—the

Attention: Parent/Guardian of [age] year old [gender] resident

Dear Resident,
Recently, a professional interviewer from RTI International 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 interview 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 precious. As a token of our appreciation, your teen will
receive $30 in cash 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.
Thank you for your time. I hope you’ll reconsider and choose to let your teenager participate in this
extremely important and beneficial study.

The initial questions for the study only take about five minutes and ask for very general information.

If anyone is selected for the full interview, that person will receive $30 in cash at the end of the

As you know, this nation is made up of all kinds of people, and therefore we are talking to all kinds of

active people like yourself would not be fairly represented. Your participation is critical to the success of
