2000 National Household Survey on Drug Abuse (NHSDA)
Data Collection Final Report

1. Introduction

The 2000 National Household Survey on Drug Abuse (NHSDA) was the twentieth in a series of general population surveys designed to provide annual nationwide data on substance abuse patterns and behaviors in the United States. Continuing the expanded sample design first implemented in 1999, the scope of the 2000 survey allowed for the production of data estimates for the nation and each of the 50 states and the District of Columbia.

The survey was funded by the Substance Abuse and Mental Health Services Administration (SAMHSA), an agency of the U.S. Department of Health and Human Services. SAMHSA chose Research Triangle Institute (RTI) to conduct activities including sampling, counting and listing, screening, interviewing, data processing, and reporting. This report examines the preparations and procedures used in carrying out the data collection tasks and also presents the results of data collection.

As an overview, preparatory work on the 2000 NHSDA began in April of 1999. Following a January training program for all returning veteran interviewers, data collection work began on January 6, 2000 and was completed by December 22, 2000. The field staff of approximately 990 field interviewers worked each month to complete a total of 71,764 interviews using computer-assisted interviewing (CAI).

Table 1.1 provides approximate time periods for the various tasks completed.

The remainder of this report addresses the following topics relating to data collection for the 2000 NHSDA: Sampling and Counting/Listing (C/L), Data Collection Staffing, Preparation of Survey Materials, Field Staff Training, Data Collection, Data Collection Results, and Quality Control.
