This study developed and validated the Cantonese integrated Digit-in-Noise Test (iDIN) for speech-in-noise measurement and hearing screening.
The development of the Cantonese iDIN followed the International Collegium of Rehabilitative Audiology guidelines. Its psychometric properties, including normative data, psychometric function, test-retest reliability, and criterion validity, were established. Additionally, a preliminary comparison of the effectiveness of 2- and 3-digit SRTs in hearing screening was conducted.
The sample included 40 young adults with normal hearing and 65 older adults, with and without hearing loss.
Mean SRTs for 2-, 3-, and 5-digit with forward recall were -11.5 ± 1.3, -12.0 ± 1.0, and -11.3 ± 0.9 dB SNR in young adults, respectively. The slopes for the psychometric functions of these sequences were 20.26, 18.61, and 19.10 %/dB, respectively, and measurement errors were 0.80, 0.61, and 0.71 dB. The area under the receiver operating characteristic curves for the 2- and 3-digit SRTs were .941 and .974, indicating high discriminative ability in hearing screening.
The Cantonese iDIN shows robust psychometric properties. Despite the 3-digit test's slightly better screening performance, shorter test during associated with the 2-digit suggests its potential for hearing screening.
本研究开发并验证了用于噪声环境下言语测量和听力筛查的粤语数字噪声综合测试（iDIN）。
粤语iDIN的开发遵循国际康复听力学学会的指南。确定了其心理测量特性，包括常模数据、心理测量函数、重测信度和效标效度。此外，还对两位数和三位数言语识别阈（SRT）在听力筛查中的有效性进行了初步比较。
样本包括40名听力正常的年轻人和65名有或无听力损失的老年人。
年轻人中，两位数、三位数和五位数正向回忆的平均言语识别阈分别为-11.5±1.3、-12.0±1.0和-11.3±0.9dB SNR。这些序列心理测量函数的斜率分别为20.26、18.61和19.10%/dB，测量误差分别为0.80、0.61和0.71dB。两位数和三位数言语识别阈的受试者工作特征曲线下面积分别为0.941和0.974，表明在听力筛查中具有较高的辨别能力。
粤语iDIN显示出稳健的心理测量特性。尽管三位数测试的筛查性能略好，但两位数测试用时较短，表明其在听力筛查中的潜力。
