Abstract
This study describes a worksite project designed to promote organ donation while testing the effectiveness of low-intensity (media-only) campaigns compared to high intensity campaigns (media+interpersonal communication), which incorporated on-site visits. All campaigns lasted 10 weeks. A total of 45 companies participated in the project, 15 in each quasi-experimental condition. Companies were counterbalanced by size of organization and industry type. Compared to the control condition, high-intensity worksite campaigns led to a six-percentage point increase in signed donor registrations while low-intensity campaigns led to a three-percentage-point increase. Both forms of worksite campaigns led to increases in attitudes, knowledge and perceived subjective norms from pretest to posttest when compared to control sites. At the same time, worksite campaigns served to significantly reduce individual-level barriers shown to be related to donation, such as medical mistrust and desire to maintain bodily integrity.
