This study investigates the test-retest distributions and the interval for true score change of the (modified) Amsterdam Inventory for Auditory Disability and Handicap [(m)AIAD], when the latter is used to measure the effect of an intervention. In a previous study the reliability and validity of the (m)AIAD in a cohort of hearing impaired patients were found to have satisfactory high values. In this prospective study, 66 patients underwent a tympanoplasty operation. Preoperatively and postoperatively pure tone audiometry was performed, and at the same time the subjective hearing ability was established by means of the (m)AIAD. The correlation between threshold change and score change was 0.35 (Pearson's r). Scores on the (m)AIAD had to change by at least 16 to be qualified as a true change. For only nine of 66 subjects this criterion was fulfilled. No clear relation exists, except for these nine subjects, between threshold change and score change in this patient population. The study also shows that disability questionnaires have their limitations, when using them to measure the result of a medical intervention in an individual patient.
本研究调查了（改良版）阿姆斯特丹听觉残疾与障碍量表[（m）AIAD]的重测分布以及真实分数变化的区间，该量表用于测量一项干预措施的效果。在之前的一项研究中，（m）AIAD在一组听力受损患者中的信度和效度被发现具有令人满意的高值。在这项前瞻性研究中，66名患者接受了鼓室成形术。术前及术后均进行了纯音听力测定，同时通过（m）AIAD确定主观听力能力。阈值变化与分数变化之间的相关性为0.35（皮尔逊r系数）。（m）AIAD的分数至少要变化16分才能被认定为真实变化。在66名受试者中，只有9名满足该标准。除这9名受试者外，该患者群体的阈值变化与分数变化之间不存在明显关系。该研究还表明，当使用残疾问卷来测量个体患者的医疗干预结果时，它们存在局限性。
