Evaluation of the validity of psychological preparation for children undergoing polysomnography

Nocturnal polysomnography (PSG) is an essential diagnostic technique to assess sleep abnormalities, including sleep-disordered breathing (SDB). Although low in invasiveness, it is extremely difficult to conduct PSG with children who are not cooperative with wearing electrodes and sensors. Particularly, it is difficult to conduct PSG on children with autism spectrum disorder (ASD) because they have poor predictive ability, exhibit extreme anxiety about novel and unfamiliar things, and have difficulty understanding verbal instructions. Recently, the usefulness of psychological preparation was reported. The primary aim of this study was to assess the usefulness of psychological preparation for PSG.
