Conducting research with racial/ethnic minorities: methodological lessons from the NIDA Clinical Trials Network.

BACKGROUND: Multiple studies in the National Institute on Drug Abuse Clinical Trials Network (CTN) demonstrate strategies for conducting effective substance abuse treatment research with racial/ethnic minorities (REMs). OBJECTIVES: The objectives of this article are to describe lessons learned within the CTN to (1) enhance recruitment, retention, and other outcomes; (2) assess measurement equivalence; and (3) use data analytic plans that yield more information. METHOD: This article includes background information and examples from multiple CTN studies on inclusion, measurement, and data analysis. RESULTS AND CONCLUSIONS: Seven recommendations are included for conducting more effective research on REMs.
