Brief Summary:
The study is to maximize efficacy of message delivery to achieve desired Obstructive sleep apnea (OSA) adherence goal. Newly diagnosed black patients (n=390, all genders) from participating sleep clinics will be randomly exposed to either the individually tailored or standard OSA messages. Investigators will look at an effective and scalable intervention to improve OSA-related outcomes: a) clinical CVD and brain health measures and b) patient-centered outcomes. Patient-centered and adherence data will be captured via REDCap, enabling real-time application of data-driven decision rules while implementing the intervention.

Arm Intervention/treatment
Active Comparator: Tailored Videos Behavioral: Tailored Videos
web-based OSA messages (videos featuring role models and coaching advice using motivational enhancement) addressing OSA barriers within a health literacy framework--to decrease cognitive load and render messages understandable and actionable. OSA messages were tailored based on focus group data in the previous study (group tailoring).

Active Comparator: Standard Videos Behavioral: Standard Videos
Patients in the control arm will also receive an iPad, providing access to standard online OSA health information (e.g., National Sleep Foundation) in an equivalent dose as in the intervention arm using pre-selected automatic alerts to access the website

Active Comparator: OSA Treatment Behavioral: OSA Treatment
Web-based platform delivering messages promoting OSA self-efficacy. . All patients will view the introductory video, followed by the video cluster: Sleep, Health, and Well-Being; Sleep-Heart Health; Lifestyle Changes; and Sleep Hygiene.

Primary Outcome Measures :
  1. Change from Baseline OSA Self-Efficacy Scale Score to 6 Months Score [ Time Frame: 2 Months and 6 Months ]
    The mean of the nonmissing item responses was calculated for each of the 3 subscales: Perceived Risk, Outcome Expectancies, and Treatment Self-Efficacy. Using this mean-weighted score prevents the distortion of the score from missing responses. Factor 1 (Risk Perception consisting of 8 questions); Factor 2 (Outcome Expectancy consisting of 9 items) and Factor 3 (Treatment Self Efficacy consisting of 9 items) are given a potential score of 1-4.
