Sex
All sexes can join.
Disease stage
Diagnosed with obstructive sleep apnea.
Earlier treatment
Must be prescribed PAP (positive airway pressure) therapy and have a device. People already using the PAP device as much as Medicaid standards ask cannot join.

About the trial

What the trial wants to find out

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).

The 2 groups in the trial

  • Intervention GroupTreatment being tested

    The CATNAP MI intervention consists of 3 Motivational Interviewing sessions to address obstructive sleep apnea (OSA), positive airway pressure (PAP) adherence, and risk of Alzheimer's disease and related dementias (ADRD) in American Indians and electronic messaging to support PAP adherence, and usual care. Data will be collected at baseline, 3-months, and 9-months.

    Treatment: CATNAP MI

  • Waitlist Control GroupNo study treatment, for comparison

    Usual care, consisting of an in-service on how to operate the PAP machine, and a mask fitting to select the most comfortable, effective mask for the individual. After 4-6 weeks of use, the participant will be contacted by Missouri Breaks Durable Medical Equipment to review objective adherence data and address any challenges or barriers to therapy such as treatment-emergent central apneas. Data will be collected at baseline, 3-months, and 9-months.
