To examine the construct validity, reliability and responsiveness of the Otology Questionnaire Amsterdam (OQUA).
Multicentre, longitudinal study in 2 separate cohorts of patients visiting an ENT surgeon via an online survey programme.
Tertiary ENT clinics.
Cohort 1 consisted of patients at their first visit at an ENT outpatient clinic with an ear complaint. Cohort 2 consisted of patients who underwent surgery, with a 3-month follow-up post-surgery.
Construct validity: Hypothesis testing, internal consistency and inter-item correlation. Reliability: Test-retest reliability. The construct approach was used for assessing responsiveness. Hypotheses were formulated based on the association between the OQUA and Glasgow Health Status Inventory (GHSI) or Global Rating Scale (GRS).
Construct validity: The correlation between the individual items in the impact domain ranged from 0.424 to 0.737. Confirmatory factor analysis showed a good fit. As expected, the OQUA impact showed strong relationships with GHSI total and general scale. Reliability: The test-retest reliability coefficient ranged from 0.541 to 0.838. Responsiveness: All hypotheses were conformed. As expected, the change score of the OQUA showed good correlation between OQUA impact and GHSI and moderate correlation between the GRS and OQUA complaints.
The OQUA has 8 complaint domains (earache, pressure sensation, itching, tinnitus, hearing loss, ear discharge, loss of taste and dizziness) and 1 impact domain. Each domain results in one score of 0-100. The OQUA shows good results for construct validity, (test-retest) reliability and responsiveness, supporting the potential benefit for the patient with an ear complaint visiting the ENT surgeon. The extensive validation furthermore confirms a certified generic otology PROM with an impact and a complaints' part, to be used in different types of otologic interventions and patient groups.
考察阿姆斯特丹耳科学问卷（OQUA）的结构效度、信度和反应度。
通过在线调查程序，在两个独立的患者队列中进行多中心、纵向研究。
三级耳鼻喉科诊所。
队列 1 由在耳鼻喉科门诊首次就诊的耳部疾病患者组成。队列 2 由接受手术的患者组成，术后 3 个月进行随访。
结构效度：假设检验、内部一致性和项目间相关性。信度：测试-重测信度。采用结构方法评估反应度。基于 OQUA 与格拉斯哥健康状况量表（GHSI）或总体评分量表（GRS）之间的关联，提出了假设。
结构效度：在影响域的各个项目之间的相关性范围为 0.424 至 0.737。验证性因子分析显示拟合良好。正如预期的那样，OQUA 对影响有很强的关系，与 GHSI 总分和一般量表有关。信度：测试-重测信度系数范围为 0.541 至 0.838。反应度：所有假设均成立。正如预期的那样，OQUA 的变化评分与 OQUA 影响和 GHSI 之间有很好的相关性，与 GRS 之间有中度相关性。
OQUA 有 8 个投诉领域（耳痛、压力感、瘙痒、耳鸣、听力损失、耳漏、味觉丧失和头晕）和 1 个影响领域。每个领域的得分范围为 0-100。OQUA 在结构效度、（测试-重测）信度和反应度方面表现良好，支持有耳部疾病就诊的患者的潜在获益。广泛的验证进一步证实了一种具有影响和投诉部分的经认证的通用耳科学 PROM，可用于不同类型的耳科干预和患者群体。
