To identify a context-effective hearing screening test for primary schools in the Western Cape, South Africa using an emic-etic framework for test selection.
A sequential mixed methods design was used to: (1) Identify test properties needed to successfully screen hearing in primary school children in the Western Cape, (2) select the hearing screening test most likely to succeed in this context, and (3) assess the use of the test in context.
Three nurses, two nursing assistants, two paediatric audiologists, and 100 grade-one children participated.
Distortion product otoacoustic emissions (DPOAEs) were identified as the test most likely to succeed as a hearing screening test in primary school children in the Western Cape. While school nurses were able to successfully apply OAE testing in this context, its sensitivity to hearing loss in these children was 57.14%.
The sensitivity would need to be improved before OAE testing could be used as a context-effective screening test for primary school children in the Western Cape. The study demonstrated the value of collaborative program planning using an emic-etic framework to ensure that screening tests are contextually appropriate.
运用主位—客位框架进行测试选择，为南非西开普省的小学确定一种具有情境有效性的听力筛查测试。
采用序贯混合方法设计，以：（1）确定在西开普省成功筛查小学生听力所需的测试属性；（2）选择最有可能在该情境下成功的听力筛查测试；（3）评估该测试在实际情境中的使用情况。
三名护士、两名护理助理、两名儿科听力学家和100名一年级儿童参与其中。
畸变产物耳声发射（DPOAE）被确定为最有可能在西开普省小学生听力筛查测试中取得成功的测试。虽然学校护士能够在这种情况下成功应用耳声发射测试，但其对这些儿童听力损失的敏感度为57.14%。
在耳声发射测试能够用作西开普省小学生具有情境有效性的筛查测试之前，其敏感度需要提高。该研究证明了使用主位—客位框架进行协作式项目规划的价值，以确保筛查测试在情境上是合适的。
