To develop and evaluate a shortened version of the Profile of Hearing Aid Benefit, to be called the Abbreviated Profile of Hearing Aid Benefit, or APHAB.
The Profile of Hearing Aid Benefit (PHAB) is a 66-item self-assessment, disability-based inventory that can be used to document the outcome of a hearing aid fitting, to compare several fittings, or to evaluate the same fitting over time. Data from 128 completed PHABs were used to select items for the Abbreviated PHAB. All subjects were elderly hearing-impaired who wore conventional analog hearing aids. Statistics of score distributions and psychometric properties of each of the APHAB subscales were determined. Data from 27 similar subjects were used to examine the test-retest properties of the instrument. Finally, equal-percentile profiles were generated for unaided, aided and benefit scores obtained from successful wearers of linear hearing aids.
The APHAB uses a subset of 24 of the 66 items from the PHAB, scored in four 6-item subscales. Three of the subscales, Ease of Communication, Reverberation, and Background Noise address speech understanding in various everyday environments. The fourth subscale, Aversiveness of Sounds, quantifies negative reactions to environmental sounds. The APHAB typically requires 10 minutes or less to complete, and it produces scores for unaided and aided performance as well as hearing aid benefit. Test-retest correlation coefficients were found to be moderate to high and similar to those reported in the literature for other scales of similar content and length. Critical differences for each subscale taken individually were judged to be fairly large, however, smaller differences between two tests from the same individual can be significant if the three speech communication subscales are considered jointly.
The APHAB is a potentially valuable clinical instrument. It can be useful for quantifying the disability associated with a hearing loss and the reduction of disability that is achieved with a hearing aid.
开发并评估听力援助益处概况的一个简短版本，称为听力援助益处简化概况（APHAB）。
听力援助益处概况（PHAB）是一个包含66个项目的自我评估、基于残疾的量表，可用于记录助听器验配的结果、比较几种验配情况或评估同一验配随时间的变化。来自128份完整的PHAB的数据用于选择APHAB的项目。所有受试者均为佩戴传统模拟助听器的老年听力受损者。确定了每个APHAB子量表的得分分布统计数据和心理测量特性。来自27名类似受试者的数据用于检验该工具的重测特性。最后，为线性助听器成功佩戴者的未助听、助听和益处得分生成了等百分位概况。
APHAB使用了PHAB中66个项目的24个项目子集，分为四个包含6个项目的子量表。其中三个子量表，沟通便利性、混响和背景噪音，涉及在各种日常环境中的言语理解。第四个子量表，声音厌恶感，量化对环境声音的负面反应。APHAB通常需要10分钟或更少时间完成，它会产生未助听和助听表现以及听力援助益处的得分。重测相关系数被发现为中度到高度，与文献中报道的其他内容和长度相似的量表的相关系数相似。然而，单独考虑每个子量表的临界差异被认为相当大，如果将三个言语沟通子量表联合考虑，同一个体两次测试之间较小的差异也可能具有显著性。
APHAB是一种潜在有价值的临床工具。它可用于量化与听力损失相关的残疾以及通过助听器实现的残疾减少情况。
