Abstract

The National Survey on Drug Use and Health (NSDUH) is an annual face-to-face, household survey. The NSDUH is sponsored by the Substance Abuse and Mental Health Services Administration. First conducted in 1971, this study has become the nation’s largest ongoing source of information on substance use behaviors. Approximately 67,500 NSDUH interviews are completed annually and data are collected in all 50 states plus the District of Columbia. NSDUH uses telephone interviewing to verify 15% of interviews completed in-person in the field and 5% of non-interview cases. Data Quality Coordinators (DQCs) use various program systems and methods to analyze and interpret the findings and ensure the highest level of data quality for the NSDUH.

This presentation will demonstrate the utility of these methods to confirm field interviewer data quality. The various modes used are telephone interview reports, follow-up call reports made by our Problem Call Back Team, and Data Quality Coordinators who analyze these reports. This verification system helps the project detect field interviewers who may be falsifying data or who are not following protocol procedures. Our presentation will highlight the telephone interviewer certification process, the telephone interview and follow-up call results and how the DQCs interpret the results to maintain superior data quality. Our goal is to present information and provide additional knowledge on procedures for maintaining data quality standards for field studies.
