No, at this time the ADNI study is not requiring participants in the ADNI Digital study or the ADNI Blood Biomarker study to have a study partner, but we strongly encourage inviting a study partner! Study partners provide valuable insights about you and your everyday functioning. If you are eligible and invited to join the In-Clinic study you will be required to have a study partner. If you are the study partner of a participant in the In-Clinic study, you may be asked to answer questions about the participant through our ADNI study website. If you (the study partner of an In-Clinic participant) complete the online questionnaires you can receive $15 eGift Cards as payment for your time (one $15 eGift Card every 6 months, if all questionnaires are completed). ADNI has partnered with Tango to provide eGift cards. Tango offers hundreds of digital gift cards as well as charitable donation options you can choose from. You can select eGift Cards from one or multiple vendors for a total of $15. The eGift Card is our way to thank you for your time and involvement in the ADNI study.
