Dear <>:
Recently, a professional interviewer from RTI International tried to contact you about your participation in a follow-up
study for the National Survey on Drug Use and Health.* You were not available at that time and have been away or
unavailable each time the interviewer has tried to reach you. Your participation in this study is important—this is why we
continue to try and reach you.
A limited number of people were selected to represent the population of the U.S. and 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.
In addition, you have the option to refuse to answer any question.
The results of this study will help state and national policymakers learn about mental health—including information on
access to and use of treatment—so that informed decisions about policies and programs can be made. By participating in
this study, you will be contributing to furthering our understanding of important health-related issues.
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 our project line to set up an appointment—the interview can
be conducted via video or telephone. We appreciate that your time is precious. As a token of our appreciation for
agreeing to participate in the main interview you received $30.
Thank you for your time. I hope you’ll choose to participate in this extremely important and beneficial study.
More information is available on the study website: https://nsduhweb.rti.org/. If you have questions about the
study, call the Project Representative at 1-800-848-4079.
Thank you for your time. I hope you’ll reconsider and choose to participate in this extremely important and
beneficial study.
