The objective was to design and validate a disease-specific outcomes instrument for use in conductive hearing loss (CHL).
The study was a retrospective survey of 47 patients recently treated for CHL with either a hearing aid or surgery. Patients were tested with the newly designed instrument (the Hearing Satisfaction Scale [HSS]), previously validated hearing-specific instruments, and a generic quality-of-life instrument.
The study was performed in an academic tertiary referral center.
These included test-retest reliability, internal consistency reliability, content validity, criterion validity, and construct validity of the HSS.
Test-retest reliability (r = 0.72, p < 0.001) and internal consistency reliability were adequate (Cronbach's alpha was 0.83 and 0.74 for the two subscales of the HSS). Criterion validity for individual items was adequate (r = 0.45, p = 0.02) using audiometric data as the criterion standard. Construct validity was also high using results from other instruments; both convergent and divergent validity of the HSS was demonstrated. In addition, the HSS demonstrated the ability to differentially discriminate between subgroups when grouped by level of hearing loss.
The HSS is a valid and reliable instrument for use in outcomes research on conductive hearing loss.
旨在设计并验证一种用于传导性听力损失（CHL）的疾病特异性结局评估工具。
本研究是一项对47例近期接受助听器或手术治疗的CHL患者的回顾性调查。患者接受了新设计的工具（听力满意度量表[HSS]）、先前已验证的听力特异性工具以及通用生活质量工具的测试。
该研究在一家学术性三级转诊中心进行。
这些指标包括HSS的重测信度、内部一致性信度、内容效度、效标效度和结构效度。
重测信度（r = 0.72，p < 0.001）和内部一致性信度良好（HSS两个子量表的Cronbach's α分别为0.83和0.74）。以听力测定数据作为标准，各项目的效标效度良好（r = 0.45，p = 0.02）。利用其他工具的结果，结构效度也较高；HSS的收敛效度和区分效度均得到证实。此外，按听力损失程度分组时，HSS能够区分不同亚组。
HSS是一种用于传导性听力损失结局研究的有效且可靠的工具。
