Objectives. To evaluate the effectiveness of video messaging on adolescent organ donor designation rates. Methods. We randomized adolescent driver education classes in Massachusetts, between July 2015 and February 2018, to receive 1 of 3 organ donation video messaging interventions (informational, testimonial, or blended). Adolescents completed questionnaires before and after the intervention and at 1-week follow-up; we compared their registration status at time of obtaining driver's license with that of a regionally matched historical comparison group. Results. Donor designation rates were higher for those exposed to video messaging than for the historical comparison group (60% vs 50%; P < .001). Testimonial (64%) and blended messaging (65%) yielded higher donor designation rates than informational messaging (51%; P = .013). There was a statistically significant messaging × time interaction effect for donation knowledge ( P = .03), with blended and informational messaging showing more gains in knowledge from before to after the intervention ( P < .001; d = 0.69 and P < .001; d = 0.45, respectively), compared with testimonial messaging ( d = 0.09; P = .22). Conclusions. Testimonial messaging is most effective in producing a verifiable and demonstrable impact on donor designation rates among adolescents, and driver education classes are an efficient venue for disseminating organ donation messaging to youths.
