摘要目的：玩具辨别测试测量儿童辨别口头单词的能力。以前的可靠性评估测试了听力正常或轻度听力障碍的儿童，大多数研究都使用没有掩蔽声音的测试版本。我们使用宽带噪声掩蔽器和两个说话者的牙牙学语评估了听力障碍儿童的重测可靠性。设计：刺激由扬声器呈现。信噪比 (SNR) 自适应变化，以估计对应于 70.7% 正确性能的语音接收阈值 (SRT)。参与者完成每个蒙面条件两次。研究样本：55 名患有永久性听力障碍的儿童参与，年龄在 3.0 至 6.3 岁之间。 34 名儿童使用了声学助听器； 21名儿童使用了人工耳蜗。结果：对于噪声掩蔽器，SRT 的受试者内标准偏差为 2.4 dB，第一和第二 SRT 之间的相关性为 + 0.73。对于杂音掩蔽器，相应的值为 2.7 dB 和 + 0.60。佩戴助听器的儿童和佩戴人工耳蜗的儿童的可靠性相似。结论：结果可以为个别儿童的分数解释提供依据。如果孩子在不同的听力环境（例如，有帮助和无帮助）下完成一个条件两次，则分数之间的差异 ≥ 7.5 dB 将具有统计显着性 (p <.05)。
Abstract Objective: The Toy Discrimination Test measures children's ability to discriminate spoken words. Previous assessments of reliability tested children with normal hearing or mild hearing impairment, and most studies used a version of the test without a masking sound. We assessed test-retest reliability for children with hearing impairment using maskers of broadband noise and two-talker babble. Design: Stimuli were presented from a loudspeaker. The signal-to-noise ratio (SNR) was varied adaptively to estimate the speech-reception threshold (SRT) corresponding to 70.7% correct performance. Participants completed each masked condition twice. Study sample: Fifty-five children with permanent hearing impairment participated, aged 3.0 to 6.3 years. Thirty-four children used acoustic hearing aids; 21 children used cochlear implants. Results: For the noise masker, the within-subject standard deviation of SRTs was 2.4 dB, and the correlation between first and second SRT was + 0.73. For the babble masker, corresponding values were 2.7 dB and + 0.60. Reliability was similar for children with hearing aids and children with cochlear implants. Conclusions: The results can inform the interpretation of scores from individual children. If a child completes a condition twice in different listening situations (e.g. aided and unaided), a difference between scores ≥ 7.5 dB would be statistically significant (p <.05).
