Hybrid Experimental Designs (HED) can be used to answer scientific questions about the integration of human-delivered and digital components and their adaptation at multiple timescales. Researchers can use HEDs to design effective Multimodal Adaptive Interventions (MADI).
Various hybrid experimental designs are possible, such as hybrids of a standard factorial design with a SMART or an MRT, or a hybrid combining a SMART and an MRT.
EXAMPLE. This SMART-MRT hybrid was devised to answer scientific questions key to the development of the multimodality adaptive intervention above. Learn more about this study.
