目的分析导致行为测试产生误差的原因。方法在491例听力损失患儿中,对7个月～2.5岁的患儿采用视觉强化测听法(VRA)或辅助行为观察法(BOA)进行测试;2.5岁以上的患儿采用游戏测听法进行测试;将裸耳听阈测试结果与听觉脑干诱发反应、40 Hz听觉诱发电位、多频稳态诱发电位等客观检查进行对比。结果裸耳听阈测试结果与客观检查结果偏差大于30 dB以上者12例,偏差在20～30 dB者16例,可信度达87.78%。而助听听阈与术后评估听阈的数值无法与客观检查进行比较。但因听阈阈值的减小易配合,偏差数值减少。可信度可增加。结论测试环境、测试设备、测试技术、家长情绪、实际工作经验、受检者以及测试者自身因素均会导致行为测试的误差。
Objective To analyze the causes of behavioral testing errors. Methods A total of 491 children with hearing loss were tested with visual augmented audiometry (VRA) or assisted-behavioral observation (BOA) in children aged 7 months to 2.5 years. Children aged 2.5 years and older underwent game audiometry Method; the naked ears hearing threshold test results and auditory brainstem response, 40 Hz auditory evoked potentials, multi-frequency steady-state evoked potentials and other objective tests were compared. Results Twelve patients with hearing loss threshold of more than 30 dB deviated from objective test results, 16 patients with deviation of 20-30 dB, and the reliability of 87.78%. However, hearing aid threshold and postoperative assessment hearing threshold values can not be compared with the objective examination. However, the decrease of threshold threshold is easy to fit and the deviation value decreases. Credibility can be increased. Conclusion The test environment, test equipment, test techniques, parental emotions, actual working experience, subject and the tester’s own factors all lead to behavioral testing errors.
