An evaluation of the effects of video modelling on the first-night effect in polysomonography examination of patients with obstructive sleep apnea

The aim of this study was to evaluate the effect on patient anxiety and first-night effect (FNE) of a video modelling application, which has an important place in behavioural information practices. A total of 232 adolescent and adult patients with suspected obstructive sleep apnea were randomly separated into groups within two age ranges using the sealed envelope method. Group 1 (14-18 years, n: 40) and group 3 (19-65 years, n: 76) were verbally informed about the polysomnography (PSG) procedure. The patients in group 2 (14-18 years, n: 37) and group 4 (19-65 years, n: 79) were shown a training video of PSG procedure. Anxiety levels of the patients in groups 2 and 4 were seen to have significantly reduced, and when these groups were compared, the decrease was seen to be more significant in the adolescent patients (p < 0.001, p = 0.001). No significant difference was determined between the values of total sleep time, REM sleep, and sleep efficiency in the video modelling groups on the 2 days (p > 0.05 for all). There was a difference between the REM latency and sleep latency values on the 2 days, and this was at a low level of significance in the video modelling group. Video modelling was seen to be effective in reducing patient anxiety and it was concluded that it could be used to reduce FNE.
