Summary

The goal of this randomized prospective clinical trial is to examine whether phenotypic traits, psychological characteristics, assessed by STAI (engl. The State-Trait Anxiety Inventory) and IPIP50S (engl. International Personality Item Pool) questionnaires, and patients' self-efficacy, assessed by SEMSA (engl. Self-Eficacy Measure for Sleep Apnea) questionnaire, are associated with CPAP adherence after three months of use. The study also evaluates whether a motivational phone call one month after therapy initiation improves CPAP adherence at the three-month follow-up. The main questions it aims to answer are:

* Are phenotypic and psychological traits associated with adherence to CPAP therapy after 3 months of treatment?
* Can a single motivational telephone intervention, one month after initiating CPAP therapy, significantly improve CPAP adherence at the three-month follow-up compared to no intervention? Researchers will compare patients who receive a phone call to those who do not, to see if this simple intervention leads to better CPAP adherence after three months of use.

Participants will:

* Undergo polysomnography before starting CPAP therapy,
* Complete three questionnaires (IPIP50S, STAI, SEMSA) before starting CPAP therapy,
* Be randomly assigned to either receive a motivational phone call one month after starting CPAP therapy or to a control group without any phone call,
* Be invited for a follow-up after three months of CPAP use to download and analyze CPAP adherence data from their CPAP devices.

Conditions

  • Obstructive Sleep Apnea (OSA)

Interventions

BEHAVIORAL

Motivational Telephone Call

This intervention consists of a single, personalized motivational telephone call delivered by a medical doctor, one month after initiation of CPAP treatment, uniquely timed to address early barriers and enhance self-efficacy. Unlike standard care or automated follow-ups, it offers tailored support based on patient experience, making it a low-cost yet targeted behavioral strategy to improve adherence. Content of the telephone call includes inquiry about patient's experience with CPAP therapy, identification of barriers to regular use, education on the health benefits of consistent CPAP usage, and personalized motivational messages aimed at increasing compliance.
