Health promotion research often includes randomized control trials (between-groups design); however, in practice, clinicians may utilize single-subject designs (within-subjects design) to evaluate the efficacy of an intervention. Within-subject experimental designs may provide additional information that cannot be gleaned from group designs (i.e., individual trends in responding); however, group designs control for many of the variations that cannot be controlled in a single-subject design (e.g., demographic variations). There are advantages and disadvantages in utilizing each type of experimental design. The purpose of the panel discussion is to review differences in within-subjects and between-groups experimental designs, discuss the strengths and limitations of each design, and make recommendations for conducting research using either methodology.
