Experimental: Psychoeducation Program

The experimental group will receive a motivational psychoeducational intervention consisting of four phases: Phase 1 (Pre-adaptation Psychoeducation): The intervention begins with the pulmonologist's decision for home adaptation to CPAP for the patient diagnosed with OSA. The participant will receive necessary materials and an educational video (25 minutes) within two days before the provider's home visit. Phase 2 (Motivational Interview): After the first night of CPAP use, the participant will have a brief motivational interview via phone. Phase 3 (Psychological Support Interview): One week after the provider's intervention, the participant will have a support interview regarding the adaptation process (40 minutes). This first week is a high-risk period for device abandonment. Phase 4 (Monitoring Interview): Two weeks after the provider's intervention, the participant will have a monitoring interview (30 minutes) to check for any difficulties during the adaptation process.

No_intervention: Treatment as usual

The patient, following the visit with the pulmonologist specializing in sleep medicine, who has been diagnosed with OSA, will be invited to proceed with the home adaptation process for the CPAP device by the staff.
