to investigate the variability of the Dichotic Sentence Test through the test and retest in normal-hearing adults.
We evaluated thirty-six individuals aged 19 to 44 years old, right-handed and with normal hearing thresholds. We performed the basic audiological evaluation and then we applied the Dichotic Digit Test and Dichotic Sentence Test. The test and retest had two sessions, with an interval from 30 to 40 days, in the same shift.
In the integration task, there was an advantage of the right ear in both evaluation sessions. There was no significant difference between the measures obtained in the right ear in the two evaluation sessions, while in the left ear, we found a significant difference. In the analysis of the differences in ears between the test and the retest, we found that 64% of the individuals kept the same result in the right ear, while in the left one, only 36% of the individuals kept the same result in both stages and 44% showed a 10% difference between the two evaluations. We observed moderate positive correlation for both the right ear (r=0.420) and the left ear (r=0.550), with a tendency to improve retest scores. In the separation task, there was a small variability only in the left ear, also with improved retest scores.
There was a significant difference between the measures obtained in the test and retest only in the integration task in the left ear, but there was a moderate positive correlation between the measures obtained in the two evaluation sessions, showing a tendency to improve scores in the second evaluation session.
通过对听力正常的成年人进行重复测试，研究双耳分听句子测试的变异性。
我们评估了36名年龄在19至44岁之间、右利手且听力阈值正常的个体。我们进行了基本的听力学评估，然后应用了双耳分听数字测试和双耳分听句子测试。重复测试有两个阶段，间隔30至40天，在同一时间段进行。
在整合任务中，两次评估阶段右耳均占优势。两次评估阶段右耳获得的测量结果之间无显著差异，而左耳则存在显著差异。在分析测试和复测之间的耳间差异时，我们发现64%的个体右耳结果相同，而左耳只有36%的个体在两个阶段结果相同，44%的个体两次评估结果相差10%。我们观察到右耳（r = 0.420）和左耳（r = 0.550）均有中度正相关，复测分数有提高趋势。在分离任务中，仅左耳有较小变异性，复测分数也有所提高。
仅在左耳的整合任务中，测试和复测获得的测量结果存在显著差异，但两次评估阶段获得的测量结果之间存在中度正相关，表明在第二次评估阶段分数有提高趋势。
