The permission for participants verbal informed consent was obtained from IRB of Beijing University of Civil Engineering and Architecture. In the project, which involved many older adults and families as participants and required face-to-face interviews, we utilized verbal consent as the primary method for obtaining informed consent because older adults are more comfortable with face-to-face interactions and verbal discussions as opposed to written consent forms. This approach facilitated better communication and allowed participants to ask questions and seek clarifications more readily. The committee overseeing our study approved the use of verbal consent in the circumstances.We believe that the combination of verbal consent and face-to-face interviews upheld the principles of informed consent while respecting the comfort and communication preferences of our older adult participants.
