What ’s New with Research Methods Resources: Stepped-Wedge Group Randomized Trials and More

David M. Murray, Ph.D., NIH Associate Director for PreventionDirector, Office of Disease Prevention When we highlighted the redesigned and expanded NIH Research Methods Resources (RMR) website last year, we hinted there would be more yet to come. We have been busy over the past several months and are happy to announce you can now find helpful resources for stepped wedge group-or cluster-randomized trials (SWGRTs) and more than 15 other study designs and methodological issues on the RMR website. Launched in 2017 by the NIH Office of Disease Prevention (ODP), the RMR website was developed as one in a series of initiatives to enhance the quality, accountability, and transparency – in short, the rigor – of NIH-supported clinical trials. The site initially focused on trials that randomize and/or deliver interventions to groups or clusters and featured a sample size calculator for parallel group- or cluster-randomized trials (GRTs). In 2021, a sample size calculator for individually randomized group treatment (IRGT) trials was added to the site along with a more modern look and user-friendly features like the ability to filter references by year, author, and type of research method. This year, we expanded the RMR website further still. A section specific to stepped wedge group- or cluster-randomized trials (SWGRTs), including a sample size calculator, has been added to the site. It provides an overview of the SWGRT design, answers to frequently asked questions, and links to imp...
