We designed this study to examine the effects of two types of incentiv
es on the participation rate of workers from two plants in worksite re
search. There were 186 workers in the study, some of whom received cha
nces for savings bonds. Given reductions in funding and concerns of ma
nagement, no comparison could be made between the incentives; however,
the study provided valuable information regarding planning for incent
ives in worksite research.
