Evaluation of Postcard Mailers Enhanced With Behavioral Nudges to Promote Mammogram Screening

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

In this evaluation, 3 different versions of mailers promoting annual mammograms are being sent to women on the month of their 50th and 64th birthdays. The researchers hypothesize that the use of behavioral nudges in the mailers should lead to increased uptake in mammogram screening.
