About the study

This research project will develop and implement a motivational interviewing and electronic messaging intervention to address obstructive sleep apnea (OSA), positive airway pressure (PAP) adherence, and risk of Alzheimer's disease and related dementias in American Indians. The project will work with American Indian Elders, aged 50 years and older, from three Northern Plains Reservations and surrounding communities. A total of 300 American Indian elders with a confirmed OSA diagnosis and prescribed PAP therapy will be randomized to receive usual care consisting of PAP therapy alone (control condition) or usual care plus the culturally informed CATNAP MI component (intervention condition).
