REDCap with Most
The goal of this manual is to show how one might setup a REDCap project to support a research study with multiple conditions, such as factorial experiments common in the Multiphase Optimization Strategy (MOST) framework.

Sometimes the conceptual model is not a model of a health behavior per se, but a model of maintaining treatment fidelity, promoting adherence or compliance, or the like. The conceptual model is explained in more detail in Chapter 2 of Collins (2018). For an example, see Gwadz et al. (2017).
A factorial experiment is essentially an RCT with a lot of experimental conditions, and therefore is extremely difficult to power.
The purpose of this page is to clarify some concepts, notation, and terminology related to factorial experimental designs, and to compare and contrast factorial experiments to randomized controlled trials (RCTs). A more in-depth introduction can be found in Chapter 3 of Collins (2018).
