During a school-based vaccination program, incentives and education we
re offered to help motivate students to participate. Each student at a
ll schools in the program received scholastic credit for returning a s
igned form, material rewards for receiving each vaccine dose, and free
attendance at a social event after completing the vaccine series. In
two of four schools, classes received a reward if every student in the
classroom returned a signed form within five days; in these schools,
91% and 98% of students returned signed forms within five days, compar
ed to 82% and 85%, respectively in the two schools without this peer i
ncentive. Approximately half the students receiving the peer incentive
reported that it played a motivating role, whereas 60% cited wanting
to be protected. Few students named individual rewards as motivators.
Although peer incentives appeared effective in encouraging some studen
ts to return parent consent or refusal forms, the desire to be protect
ed may have been a stronger motivator.
