Dear Resident:
Recently, a Field 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 for participating.
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 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, telephone me toll-free at [TOLL FREE
NUMBER].

Attention: [age] year old [gender] resident

Dear Resident:
Recently, a Field 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 people you represent—
will not be heard.
Your answers to the survey questions are combined with the answers of other people and reported only as overall
numbers. To further protect your privacy, 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.
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 a precious commodity. 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
2012 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 field interviewer will carry a personal identification letter which is provided by the Substance Abuse
and Mental Health Services Administration (SAMHSA), the agency within DHHS that sponsors the study. This letter serves as
documentation that SAMHSA formally authorizes the interviewer to work on the NSDUH for RTI.

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 hand-held 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 hand-held computer 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 2010 Study
Each year SAMHSA releases results of the study, and this document highlights some of the findings from the 2010
NSDUH.

far, [MR./MS.] [LAST NAME] has been unable to [GAIN ACCESS/GAIN FULL ACCESS] to [NAME
OF COMPLEX/COMMUNITY], and we are asking for your help.
We understand your responsibility to protect your residents and want to provide you with additional
information about the study:
 We are not selling anything. This is not a marketing survey.


The National Survey on Drug Use and Health (NSDUH) provides valuable national and state-level
information about important health-related issues including experiences with and opinions about
the use or non-use of alcohol, drugs, and tobacco. For this reason, it is just as important that we
talk to people who have not used drugs as it is that we talk to people who have.



A limited number of household addresses were randomly chosen to take part. We do not have any
information about the residents other than an address.



The RTI interviewer only needs a few minutes of the residents’ time to see if someone in the
household will be asked to participate in an interview. If selected, those completing the interview
receive a cash incentive.



All information provided is kept completely confidential.



For more details about the study, please visit http://nsduhweb.rti.org

By helping our interviewer access the selected households in [NAME OF COMPLEX/COMMUNITY],
you will make a direct contribution to this important research effort. [FIRST & LAST NAMES], our
supervisor in your area, will contact you soon to address any questions, or you may call [HIM/HER] toll

Your assistance is extremely important to the success of this study, and I thank you in advance for your
help.

Dear Resident:
Recently, a Field 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 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 $30 in cash at
the end of the interview.
We combine your answers with the answers 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

Dear Resident,
Recently, a Field 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 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 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 $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
