The aim of the present study was to investigate the validity of a community-based hearing test to detect conductive hearing loss in 3-year-old children. Sixty-five children had their hearing tested using standard audiological tests at the same time as they underwent their 3-year-old health checks. The checks were performed by health visitors at community health clinics, and included the McCormick Toy Test (MCTT) for hearing. Fourteen children failed both tests and none passed the MCTT and failed the standard tests, giving a sensitivity of 100%. Forty-eight children passed both tests and three children failed the MCTT but passed the standard tests, giving a specificity of 94%. Positive predictive value was 82%. The results from this sample indicate that the MCTT may be used as a valid test for conductive hearing loss for 3-year-old children in the community setting.
本研究的目的是调查一项基于社区的听力测试在检测3岁儿童传导性听力损失方面的有效性。65名儿童在进行3岁健康检查的同时，使用标准听力测试进行了听力检测。这些检查由社区健康诊所的健康访视员进行，其中包括用于听力检测的麦考密克玩具测试（MCTT）。14名儿童两项测试均未通过，没有儿童通过MCTT但标准测试未通过，灵敏度为100%。48名儿童两项测试均通过，3名儿童MCTT未通过但标准测试通过，特异性为94%。阳性预测值为82%。该样本的结果表明，MCTT可作为社区环境中3岁儿童传导性听力损失的有效检测方法。
