What are the purposes of this investigation?

"Over a two-week period, the researchers aim to track and assess Apnea Hypopnea Index (AHI) as well as measure sleep disturbance using Patient-Reported Outcomes Measurement Information System's Sleep Disturbance Assessment scale with T-scores indicating levels of disruption. Additionally, they will evaluate Sleep Related Impairment (SRI) via PROMIS 8 item instrument also scored on T-scale for comparative analysis against baseline values in US general population. Lastly, Epworth Sleepiness Scale is used to gauge likelihood of dozing off in various scenarios ranging from 0 to 3 points per activity summed up for an overall" - Anonymous Online Contributor
