Researchers from the Health and Retirement Study have found that roughly 2/3 of individuals invited to complete a household screening questionnaire online are choosing to access the screening questionnaire via a QR code provided in the invitation letter. Of note, 71% of responding Hispanics chose to use the QR code, and 17% of screeners completed via the QR code were from Hispanics. This study therefore presents initial evidence of the benefits of using QR codes during recruitment of older Hispanic populations.
