Researchers are evaluating a culturally informed motivational interviewing and electronic messaging intervention called CATNAP to support American Indian elders with obstructive sleep apnea OSA and prescribed positive airway pressure PAP therapy. This 9-month study focuses on improving PAP adherence and exploring the link between OSA and cognitive changes, including the risk of Alzheimers disease and related dementias ADRD. The trial includes 300 American Indian elders aged 50 years and older from Northern Plains Reservations and nearby communities. Participants will be randomized to either usual care or an intervention group receiving the CATNAP motivational interviewing sessions alongside electronic messages to encourage PAP use. The intervention involves three motivational interviewing sessions to increase knowledge about OSA, sleep health, and PAP adherence, plus personalized electronic messages. Usual care includes mask fitting, PAP machine training, and follow-up for adherence support. Data collection occurs at baseline, 3 months, and 9 months. During the study, researchers will monitor PAP use automatically via cloud uploads provided by Missouri Breaks Durable Medical Equipment. Outcomes measured include PAP adherence minutes and nights of use, plus cognitive function assessed by the Montreal Cognitive Assessment and Cognivue tests. The study aims to understand PAP adherence patterns and cognitive outcomes while assessing intervention impacts over the 9-month period.
