State Data User Survey


SUPPORTING STATEMENT



1. Purpose and Use of Information

The National Survey on Drug Use and Health (NSDUH) sponsored by the Substance Abuse and Mental Health Services Administration (SAMHSA) and managed by the Office of Applied Studies (OAS) within SAMHSA, is a national survey of the U.S. civilian non-institutionalized population aged 12 and older. The NSDUH is used to meet a critical objective of SAMHSA’s mission, i.e., to maintain current data on the prevalence of substance use in the United States.


Since 1999, SAMHSA has produced estimates at the State and substate levels for a selected set of variables. State estimates are produced using a small area estimation (SAE) procedure in which State-level NSDUH data are combined with local-area county and census block group/tract-level data from the State. These model-based estimates provide a more precise representation of substance use at the State level than can be produced based solely on the survey data, given the smaller State sample sizes.


This package is submitted under the NSDUH Methodological Field Tests generic OMB clearance (OMB No. 0930-0290). SAMHSA is requesting approval to gather information on State data needs. The information collected will be used to identify potential areas for changes in the NSDUH and the resulting data products that would improve the utility for State users. This survey will collect information on:


  • the use of NSDUH data products

  • questionnaire topics used most frequently by the States

  • proposed new topics

  • the overall NSDUH data collection strategy

2. Use of Information Technology

Data will be collected through a self-administered web-based survey on a secure site maintained by the NSDUH Contractor, RTI International.

  1. Efforts to Identify Duplication


There have been no other systematic efforts to identify how States use data from the NSDUH. Thus this survey will not lead to any duplication of data collected.


4. Consequences if Information Collected Less Frequently

The information collected from this survey will be used in planning for NSDUH updates. These updates will be implemented in the 2012 survey. The timetable for testing and implementing the changes dictates that this survey of State users be completed by mid-June, 2008. This is a one-time survey.


5. Consultation Outside the Agency

OAS has consulted with other experts within SAMHSA, including staff from the Center for Substance Abuse Treatment (CSAT), since they work closely with the States. There are no unresolved issues resulting from these consultations.


6. Payment to Respondents

Participants will not be paid for this interview.


7. Methods to Maintain Confidentiality


No confidential data will be collected in this survey. States will be asked whether and how they use the data, and to solicit suggestions for changes to the survey that would increase its utility. Final reports will describe States’ use of the data and suggested changes to the survey. There are no plans to disseminate these reports outside of SAMHSA.

8. Questions of a Sensitive Nature


No sensitive data will be collected in this survey.


9. Estimates of Annualized Hour Burden


Data will be collected about each State and the District of Columbia. Most of the States will have a single respondent; however, it is expected that a quarter to a third of the States may require a discussion with a second person who uses NSDUH data to get a complete picture of State data use and need. Therefore, approximately 65 participants are expected to complete the survey.


Completion of the questionnaire will take an average of 15 minutes per participant.


The field period for this study will span approximately four weeks.


The respondent burden for this study is shown in the following table. The hourly wage of $30.00 was calculated based on salaries of Single State Agency (SSA) program staff responsible for completing the Substance Abuse Prevention and Treatment (SAPT) Block Grant applications. In most States, these persons will respond to the State data use survey.

10. Estimates of Annualized Cost to the Government


Total costs associated with the 2008 NSDUH State Data User Survey are estimated to be $57,400 over a 12-month performance period. Of the total costs, $52,000 is for contract costs (e.g., study design, preparation of materials, designing and implementing the web application, analysis, and report writing) and $5,400 represents SAMHSA costs to manage the survey.


  1. Time Schedule, Publication and Analysis Plans


The 2008 NSDUH State Data User Survey results will be used in the design of the 2012 NSDUH survey. The State Data User Survey is not designed for statistical inference, but instead to gain an understanding of the different ways NSDUH data are used by States. The data collected will be compiled for internal usage in the form of a simple descriptive report.


The time schedule for the 2008 NSDUH State Data User Survey is included below.

12. Respondent Universe and Sampling Methods


The goal of this survey is to understand how States use the substance abuse and mental health data that are collected in the NSDUH. In most States it is anticipated that a single point of contact, identified through our work with the States in defining analytical substate areas, will be able to provide this information. In a quarter to about a third of the States, a second person may have to be interviewed to get additional details. This survey will not include any sampling—data are being collected from all 50 States and the District of Columbia. No statistical inferences will be made—the goal is to develop a better understanding of the different ways in which States use NSDUH data.


13. Information Collection Procedures


The respondents will be 51 key State data users identified by CSAT through their work with the States. These State agency contact persons will be notified about the survey via email (Attachment A). The email will contain information on the survey topics, and a link to the web-based survey. These contact persons will be asked to complete the survey within the following two weeks. Attachment B contains the survey questionnaire.


14. Methods to Maximize Response Rates


At the end of the first week of the field period, participants who have not yet responded will receive a reminder email (Attachment C). At the end of the second week, RTI will attempt to contact nonrespondents by phone to remind them about the survey. At that point, if the respondents prefer, they will be given the option of completing the survey over the phone. To assure a high rate of participation, State agency contacts will receive up to five follow-up call attempts. Participants who cannot be contacted by phone and/or have not responded by the end of the third week will be sent a final reminder email (Attachment D) to solicit their participation. If a respondent is unable or refuses to participate, they will be asked to identify an alternate person who knows how their State uses NSDUH data. Based on our multi-mode approach, 45 of the 51 States are expected to respond (i.e., a response rate of 88 percent). Our goal is to get a 100 percent response rate, and given the salience of the topic for the States, the simplicity of the questionnaire and the small number of respondents it is not an unreasonable goal.


15. Tests of Procedures

This questionnaire is very short and straight-forward and has been reviewed by experts who work with the NSDUH data and with staff in CSAT who work with these State contacts persons.
