The Rothman Model

The Rothman Model is a framework used to understand how different factors contribute to the occurrence of diseases. It emphasizes that diseases result from the interaction of multiple causes rather than a single factor. The model outlines three key elements: necessary causes (factors needed for the disease to occur), sufficient causes (combinations of factors that can lead to the disease), and component causes (individual factors that contribute to sufficient causes). By analyzing these interactions, public health professionals can better identify risk factors and design effective prevention strategies.
