About This Webinar
For many years, prevention interventions have been developed by creating or selecting intervention components, assembling the components into a treatment package, and evaluating the package in a randomized controlled trial (RCT). Recently an alternative framework has been developed, called the multiphase optimization strategy (MOST). Inspired by approaches that are standard in fields such as industrial engineering, MOST emphasizes development of an optimized intervention before an RCT is considered. The information needed for optimization is gathered in an optimization trial. Based on the results of this trial, the investigator can eliminate underperforming components. If desired, the investigator can select from among the remaining components with cost (broadly defined) as a criterion—for example, can select the subset of components that provides the best expected outcome that can be obtained within some upper limit on implementation cost.
Dr. Linda M. Collins will briefly describe the MOST framework for optimizing and evaluating behavioral, biobehavioral, and biomedical interventions—and contrast it to the classical treatment package approach. She will review examples of recent and current applications of MOST and will discuss where she sees the field of intervention optimization going, including future methodological directions.
