Experimental Study Designs in Public Health Explained

Dive into the world of experimental study designs in public health! This video covers the four core designs: Randomized Controlled Trials (RCTs) for the gold-standard causal evidence; Cluster RCTs for community-level interventions; Crossover Trials where participants act as their own controls; and Factorial Trials for testing multiple interventions simultaneously. Learn each design’s structure, application examples, advantages—like bias reduction in RCTs or efficiency in factorial designs—and key limitations, such as ethical considerations, sample-size requirements, and complex analysis methods. With vivid icons and animated flowcharts, you’ll understand when and how to choose the right experimental approach to answer critical public-health questions.
