To investigate the effectiveness of an at-home frequent-word auditory training procedure for use with older adults with impaired hearing wearing their own hearing aids.
Prospective, double-blind placebo-controlled randomized trial with three parallel branches: an intervention group who received the at-home auditory training; an active control group who listened to audiobooks using a similar platform at home (placebo intervention); and a passive control group who wore hearing aids and returned for outcomes, but received no intervention. Outcome measures were obtained after a 5-week period. A mixed research design was used with a between-subjects factor of group and a repeated-measures factor of time (pre- and post-treatment) to evaluate the effects of the at-home auditory training program. The intervention was completed in participants' own homes. Baseline and outcomes measures were assessed at a university research laboratory. The participants were adults, aged 54 to 80 years, with the mild-to-moderate hearing loss. Of the 51 identified eligible participants, 45 enrolled as a volunteer sample and 43 of these completed the study. Frequent-word auditory training regimen completed intervention at home over a period of 5 weeks. The active control group listened to audiobooks (placebo intervention) and the passive control group completed no intervention. The primary outcome measure is a Connected Speech test benefit. The secondary outcome measure is a 66-item self-report profile of hearing aid performance.
Participants who received the at-home training intervention demonstrated significant improvements on aided recognition for trained materials, but no generalization of these benefits to nontrained materials was seen. This was despite reasonably good compliance with the at-home training regimen and careful verification of hearing aid function throughout the trial. Based on follow-up post-trial evaluation, the benefits observed for trained materials in the intervention group were sustained for a period of at least 8.5 months. No improvement was seen for supplemental outcome measures of hearing aid satisfaction, hearing handicap, or tolerance of background noise while listening to speech.
The at-home auditory training procedure utilizing frequently occurring words was effective for the trained materials used in the procedure. No generalization was seen to nontrained materials or to perceived benefit from hearing aids.
研究一种在家使用的常见词听觉训练程序对佩戴自身助听器的听力受损老年人的有效性。
前瞻性、双盲安慰剂对照随机试验，分为三个平行分支：接受家庭听觉训练的干预组；在家中使用类似平台听有声读物的主动对照组（安慰剂干预）；以及佩戴助听器并进行结果评估但未接受干预的被动对照组。在 5 周后获得结果测量。采用混合研究设计，采用组间因素和时间（治疗前和治疗后）重复测量因素来评估家庭听觉训练计划的效果。干预在参与者的家中完成。在大学研究实验室进行基线和结果测量。参与者为年龄在 54 至 80 岁之间的成年人，有轻度至中度听力损失。在确定的 51 名合格参与者中，有 45 名作为志愿者样本入组，其中 43 名完成了研究。常见词听觉训练方案在 5 周内完成在家中的干预。主动对照组听有声读物（安慰剂干预），被动对照组不进行干预。主要结果测量是言语可懂度测试的益处。次要结果测量是 66 项助听器性能自我报告表。
接受家庭训练干预的参与者在辅助识别训练材料方面有显著改善，但未观察到这些益处扩展到未训练材料。尽管家庭训练方案的依从性较好，并且在整个试验过程中仔细验证了助听器的功能，但仍出现这种情况。基于试验后随访评估，干预组观察到的训练材料的益处至少持续了 8.5 个月。助听器满意度、听力障碍或在听言语时对背景噪声的容忍度等补充结果测量没有改善。
使用常见词的家庭听觉训练程序对程序中使用的训练材料有效。未观察到对未训练材料或对助听器感知益处的泛化。
