Increasing Donor Designation Rates in Teenagers: Effectiveness of a Driver's Education Intervention

The primary outcome was donor designation (yes-no) at time of obtaining first driver's license post-intervention. We provided the name, date of birth, last four digits of social security number, residential address, and study identification number of each adolescent to the Massachusetts DoT, which then returned to us a data file containing the donor designation status for each study identification number. For the regionally-matched historical comparison group, the DoT provided a de-identified data file of all adolescents who obtained their first driver's license in the six months prior to study enrollment at six motor vehicle offices.

Immediately before, shortly after, and 1 week following video messaging exposure, adolescents completed a questionnaire to assess the following donation constructs: engagement (2 questions -- 1-10 scale), knowledge (3 questions -- correct/incorrect total score range 0-3), general attitude (1 question), beliefs (4 questions -- strong disagree-strongly agree scale), designation likelihood (1 question -- 1-10 scale), and willingness to communicate donation decision to a parent (1 question -- 1-10 scale). Adolescents received a $5 gift card for each survey completed.

One week following the adolescent's exposure to the donation video, we mailed parents a brief questionnaire that included questions about their donor designation status (Yes/No), general donation attitude (1 question -- 1-10 scale), any communication with their adolescent about his/her donor designation intention (Yes/No), and likelihood of following their adolescent's wishes about donation (1 question -- 1-10 scale).
