Rationale for factorial experiments

These articles review practical aspects of experimental design relevant to intervention science, and also attempt to correct some pervasively held misconceptions. These articles provide a rationale for considering a factorial experiment and may be useful citations.

Enhancing effectiveness through MOST

This article addresses the question “Is MOST really likely to produce more potent behavioral interventions in practice?” by means of an extensive statistical simulation:
