Presented by Edward V. Nunes, PhD (New York State Psychiatric Institute, GNY Node), Aimee N. C. Campbell, PhD, MSW (Columbia University, GNY Node).

Produced by the NIDA Clinical Trials Network's Clinical Coordinating Center, May 25, 2016.

The National Drug Abuse Treatment Clinical Trials Network WEB-TX study is one of the largest randomized controlled trials to date examining the effectiveness of an internet-delivered treatment intervention on clinical outcomes among people receiving outpatient substance abuse treatment.

In addition to the primary outcome analysis showing significant improvements in abstinence and treatment retention among people randomized to the internet-delivered treatment arm, the study has produced three methodological publications, four baseline publications, five secondary outcome publications, and an additional seven secondary outcome publications under review or in preparation.

The purpose of this one-hour webinar, presented by Edward Nunes, MD and Aimee Cambell, PhD, was to present a synthesis of WEB-TX study findings focusing on key secondary clinical outcomes and discuss new areas of research for technology-based treatments for substance use disorders.


  • Understand the design and methodological decisions critical to the implementation of an effectiveness trial of a technology-based intervention.
  • Review the primary outcomes and key secondary outcomes of the WEB-TX study.
  • Discuss new areas of research for technology-based interventions.

This webinar is aimed at all interested investigators, clinicians, statisticians, and other research staff. (Webinar, Video, PDF, English, 2016)
