Objectives:
Comparing the output of two subjective self-evaluating sleep questionnaires commonly used in adult populations at-risk for sleep disorders, focusing on sleepiness and insomnia symptoms, to automated CardioPulmonary Coupling (CPC) analysis of electrocardiography (ECG) data collected during sleep, to measure sleep quality.
Conclusions:
Sleep questionnaires have low sensitivity, specificity and agreement when compared to objective sleep measures.
Practical Significance:
The need to add an objective measure of sleep physiology and pathology to subjective patient self-evaluation of sleep quality when screening for sleep disorders can be solved with this simple, FDA-cleared method to evaluate sleep and sleep disorders.
