Abstract

Objectives: This study aimed to develop and evaluate a Ghanaian Digit Triplet Test for adult hearing screening.

Design: The study was conducted in two phases. Phase 1 optimised digit recognition across speech materials in a controlled environment, while Phase 2 collected normative data and assessed list equivalence using an adaptive and fixed-level method.

Study sample: Eighty adults aged 18 to 50 years with normal hearing thresholds (≤ 15 dB HL) participated: 16 in Phase 1 and 64 in Phase 2.

Results: The mean SRTs were -11.3 dB for Asante-Twi and -11.4 dB for Ghanaian English, closely matching other digit triplet tests. Psychometric slopes were 17.9%/dB for Asante-Twi and 19.4%/dB for Ghanaian English. No significant differences were found in SRTs across list numbers or orders for the Asante-Twi version, indicating list equivalence and no learning effect. However, a significant learning effect in the Ghanaian English version necessitated different normative values based on participants' test exposure.

Conclusions: The GDTT demonstrates consistency with other digit triplet tests while addressing specific linguistic and cultural factors. The test can improve access to hearing screening in resource-limited settings in Ghana. Further research should explore the test's applicability to a broader demographic, including children.

加纳成人听力筛查手指三联体试验的发展和评价。

目的：本研究旨在开发和评估加纳手指三联体测试成人听力筛查。设计：本研究分两个阶段进行。第一阶段在受控环境中优化语音材料的数字识别，而第二阶段收集规范数据并使用自适应和固定水平方法评估列表等效性。研究样本：80名年龄在18至50岁之间，听力阈值正常（≤15 dB HL）的成年人参与其中：16名在第一阶段，64名在第二阶段。结果：Asante-Twi的平均srt为-11.3 dB，加纳英语的平均srt为-11.4 dB，与其他数字三连音测试密切匹配。Asante-Twi的心理测量斜率为17.9%/dB，加纳英语为19.4%/dB。在Asante-Twi版本中，不同列表编号或顺序的srt没有发现显著差异，表明列表等效，没有学习效果。然而，加纳英语版本的显著学习效果需要根据参与者的测试暴露不同的规范值。结论：GDTT在处理特定的语言和文化因素时，与其他数字三连音测试表现出一致性。在加纳资源有限的环境中，这种测试可以改善获得听力筛查的机会。进一步的研究应该探索该测试是否适用于更广泛的人群，包括儿童。
