Primary Outcome Measures
NameTimeMethod
Proportion of participants adherence to OSA treatmentUp to 6 months

The proportion of participants who answer yes (meaning a participant acknowledges an average of more than 4 hours of continuous positive airway pressure use) or no (meaning a participant acknowledges an average of less than 4 hours of continuous positive airway pressure use).

Change in NIH Toolbox- Flanker Inhibitory Control and AttentionBaseline, 6 months

An assessment of inhibitory control and attention. The participant is asked to focus on a particular stimulus while inhibiting attention to the stimuli flanking it. This outcome will be reported as a composite score.

Change in Working Memory measured by List Sorting TaskBaseline, 6 months

Working memory, An assessment of working memory. The participant is asked to recall and sequence different stimuli that are presented visually and via audio.
