About this study
This study intends to investigate the personality and psychological characteristics of OSA patients using classical standard scales and obtain treatment information and adherence data through prospective follow-up to summarize the distribution characteristics of mood and personality characteristics of OSA patients and their influence on treatment adherence. A thorough understanding of OSA patient characteristics from the perspective of personality and psychological characteristics will be of great significance to the classification of OSA patients, precision treatment, and improving treatment compliance.
Read the detailed description
This study will establish a prospective cohort to conduct the study in two parts.
- Through the personality, mood, and sleep questionnaires of patients with suspected OSA and planned sleep monitoring, the differences in personality and treatment choices of the OSA population with different personality characteristics and emotional states through follow-up.
- The above investigation and follow-up of patients in the hospital for ventilator pressure treatment were used to observe the effect of differences in personality characteristics and mood status on ventilator treatment acceptance, stress, and compliance indicators.
- Conditions
- Personality, Patient Compliance, Anxiety, Depression, Continuous Positive Airway Pressure (CPAP)
- Being tested
- continous positive airway pressure (CPAP)
- Keywords
- Obstructive sleep apnea, personality, patient compliance, Anxiety, depression, Continuous Positive Airway Pressure (CPAP)

| Study group | Role | What they receive |

| non-OSA | dignosis OSA according to the sleep study (AHI <5) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Eysenck Personality Questionnaire (EPQ)
This study adopted the classic short form of the Eysenck Personality Questionnaire - Revised (EPQ-R Short Scale) to assess individual personality traits across four dimensions: Psychoticism (P), Extraversion (E), Neuroticism (N), and Lie Scale (L). Each dimension consists of 12 items, with scores ranging from 0 to 12. Higher scores indicate a stronger presence of the corresponding trait. For example, a higher score on Neuroticism reflects greater emotional instability, while a higher score on Extraversion suggests a more outgoing and active personality
Measured: At baseline
Secondary outcomes (1)
continuous positive airway pressure (CPAP) compliance
downloading the data from the CPAP to assess average daily usage duration (in hours) and the number of days used per week. Good adherence is typically defined as using the CPAP device for at least 4 hours per night on 70% or more nights over the past 3 consecutive months.
Measured: From CPAP initiation to the 3-month follow-up
