Reliability and validity of a Thai version of the Berlin questionnaire in patients with sleep disordered breathing
Objective:
To assess the validity and test-retest reliability of a Thai version of the Berlin Questionnaire in patients with sleep disorder breathing. MARTIAL AND METHOD: Patients who were suspected of sleep disordered breathing attending the outpatient department of Siriraj Hospital and who had undergone polysomnography were recruited and asked to complete a Thai version of the Berlin questionnaire. Each participant was asked to repeat the same questionnaire over the next 2-4 weeks for test-retest reliability.
Results:
One hundred and thirty-two patients completed the present study. The age range of the patients was 26-72 years (mean, 48.15 ++/- .80 years). All 10 items of the Thai version of the Berlin questionnaire were moderately correlated in internal consistency (Cronbach's alpha correlation coefficient = 0.68). The test-retest reliability of the Thai version of the Berlin questionnaire was investigated in 98 patients and demonstrated a high degree of reliability in intra class correlation (ICC = 0.97).
Conclusion:
The present study reveals, for the first time, that the Thai version of the Berlin questionnaire has satisfactory validity and reliability when compared to the original English version.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
