What this trial studies

This is a prospective observational cohort at Peking University First Hospital enrolling adults aged 18–70 with suspected or confirmed OSA. Participants complete standardized personality, mood, and sleep questionnaires before sleep monitoring or CPAP titration and are followed over time to record treatment choices and adherence. The study has two parts: comparing personality and mood across patients with different treatment choices, and tracking CPAP acceptance, stress, and objective compliance measures in patients receiving ventilator therapy. Findings will describe the distribution of psychological traits in OSA patients and their relationship to treatment adherence.

Who should consider this trial

Good fit: Adults 18–70 with suspected or confirmed OSA who are cognitively independent and willing to consent, complete questionnaires, and attend sleep testing or CPAP titration are ideal candidates.

Not a fit: People under 18 or over 70, those without OSA symptoms or a confirmed diagnosis, or those unable or unwilling to complete questionnaires or consent are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, findings could help clinicians tailor support and treatment plans to patients' mood and personality to improve CPAP acceptance and adherence.

How similar studies have performed: Previous studies have linked mood and personality to CPAP adherence but results are mixed, so this study builds on existing but not definitive evidence.
