Brenna Renn (Psychology) published "Behavior change factors and retention in dietary interventions for older adults: Scoping review" in The Gerontologist. This work, done in conjunction with colleagues and students at the University of Washington School of Nursing, mapped behavior change theories, agents, and techniques in dietary interventions for older adults (60-plus) and explored relationships between these factors and ability to retain at least 80 percent of the study participants in research trials.
