背景资料：与传统助听器不同，智能手机连接的听音设备在设备编程和调整方面可能需要来自训练有素的听力学家的有限输入或不需要输入。然而，缺乏同行评审的证据来评估听力损失患者对这些技术创新的现实观点。目的：本研究使用能力、机会、动机、行为（COM-B）模型作为理论框架，评估了听力损失成年人对一系列智能手机连接听音设备的日常体验。研究设计：在一项定性研究中，参与者在日常生活中试用了以下智能手机连接的听力设备之一两周：智能手机助听器，个人声音放大产品，以及带有有线耳机或无线耳机的智能手机“助听器”应用程序。研究样本：20名成年人（13名男性和7名女性;平均年龄= 62.25岁，SD = 11.59）与轻度至中度听力损失（平均更好的耳朵纯音平均值= 30.49 dB HL，SD = 17.51）被招募使用方便的抽样策略。所有的参与者都拥有传统的助听器。数据分析：数据进行了分析，使用一个既定的演绎主题分析程序的背景下的COM-B模型。该模型规定，个体要从事特定行为（B），必须具备足够的能力（C）、机会（O）和动机（M）。促进使用和坚持使用智能手机连接的听音设备的关键优势之一是参与者能够在任何听音情况下进行微调。机会与会者评论说，这些设备可以解决围绕耻辱的问题，因为智能手机在日常生活中无处不在。动机：参与者一致表示，通过智能手机进行调整的能力为他们提供了更大的自主权和授权感。结论：这项研究为进一步的高质量研究奠定了基础，以探索智能手机连接技术是否有潜力为听力损失患者带来最佳益处。
Background: Unlike conventional hearing aids, smartphone-connected listening devices may require limited or no input from a trained audiologist in terms of device programming and adjustment. However, there is a lack of peer-reviewed evidence assessing the real-world perspectives of people living with hearing loss toward such technological innovations.Purpose: This study assessed the everyday experiences of adults living with hearing loss toward a range of smartphone-connected listening devices using the Capability, Opportunity, Motivation, Behaviour (COM-B) model as a theoretical framework.Research Design: A qualitative study where participants trialed one of the following smartphone-connected listening devices for two weeks in their everyday lives: made-for-smartphone hearing aid, personal sound amplification product, and smartphone "hearing aid" app with wired earphones or wireless hearable. Individual semistructured interviews were conducted.Study Sample: Twenty adults (13 male and 7 female; mean age = 62.25 years, SD = 11.59) with mild-to-moderate hearing loss (mean better ear pure-tone average = 30.49 dB HL, SD = 17.51) were recruited using a convenience sampling strategy. All participants owned conventional hearing aids.Data Analysis: The data were analyzed using an established deductive thematic analysis procedure within the context of the COM-B model. The model stipulates that for individuals to engage in a particular behavior (B), they must have sufficient capability (C), opportunity (O), and motivation (M).Results: Capability. One of the key advantages facilitating use and adherence of smartphone-connected listening devices was the ability for participants to make fine-tune adjustments in any listening situation. Opportunity. Participants commented that these devices could address issues surrounding stigma as smartphones are ubiquitous in everyday life. Motivation: Participants consistently reported that the ability to make adjustments via a smartphone provided them with a greater sense of autonomy and empowerment. As a result, they felt more in control of their hearing loss.Conclusions: This study lays the foundation for further high-quality research to explore whether smartphone-connected technologies have the potential to yield optimum benefits for people living with hearing loss.
