Summary Polysomnography is the only internationally recognized method to diagnose paediatric obstructive sleep apnea, thus, simpler and more cost‐effective diagnostic tools are urgently needed. This study aimed validate manual scoring of frontal self‐applicable electroencephalography against polysomnography in a cohort. The were simultaneously recorded for 1 night ( n = 102) 10–13‐year‐old children. Scoring was performed according American Academy Sleep Medicine rules, with minor adjustments electroencephalography. Manual scorings stages compared an epoch‐by‐epoch manner using Cohen's kappa (κ) confusion matrices three different models: three‐stage (wake/non‐rapid eye movement/rapid movement), four‐stage (wake/sleep stage + 2/deep Stage 3/rapid movement) five‐stage model 1/sleep movement). inter‐scorer agreements assessed, intraclass correlation coefficient used common variables: total time, wake after onset, efficiency, sleep‐onset latency arousal index. κ values three‐stage, models 0.85, 0.73 0.70, respectively. agreement variables studied ranged from 0.87 0.99. inter‐rater 10) 0.78 0.70 staging comparable that standard cohort, showed promising results estimating time architecture.
