Electrophysiological sleep studies employ the simultaneous recording of multiple physiological parameters. These data are often scored and analyzed visually, i.e. by trained human scorers. In this study, we investigated the measurement error inherent in visual evaluation of respiratory disturbances during human sleep. Three trained scorers independently evaluated twenty-eight all-night sleep recordings. Results indicated that the scorers achieved high agreement on only selected variables. Scorers' experience did not affect the reliability and independent judgements of recording quality did not account for the discrepancies. These findings, although most relevant for the specific parameters studied here, as well as for these scoring criteria, subjects, and techniques, document the unreliability of certain visually scored sleep data. The present paradigm may be useful in evaluating other types of measurement error.
电生理睡眠研究采用同时记录多个生理参数的方法。这些数据通常由经过训练的人员进行视觉评分和分析。在本研究中，我们调查了人类睡眠期间呼吸紊乱视觉评估中固有的测量误差。三名经过训练的评分员独立评估了28份整夜睡眠记录。结果表明，评分员仅在选定变量上达成了高度一致。评分员的经验并未影响可靠性，记录质量的独立判断也无法解释差异。这些发现虽然与这里研究的特定参数以及这些评分标准、受试者和技术最为相关，但证明了某些视觉评分睡眠数据的不可靠性。目前的范式可能有助于评估其他类型的测量误差。
