目的（1）应用项目反应理论（IRT）对听力康复仪的11个项目的内部效能进行评定。(2)确定潜在的潜在能力是否也可以由用于大量临床场景的项目子集准确表示。(3)确定是否与纯音听阈和单词识别scores.Design IRT评价的前瞻性队列数据设置三级保健学术门诊耳鼻喉科clinics.Subjects和方法现代心理测量学方法，包括因素分析和IRT，被用来评估单维度和项目属性。结果内隐量表是一维的，条目的位置和信息各不相同。信息参数估计值从1.63到4.52不等，数值越高，说明项目越有用。IRT模型为识别两组信息参数相对较低的项目提供了依据。项目信息功能表明，哪些项目增加了非实质性的价值超过其他项目，并被删除的阶段，创建一个8和3个项目的内部量表更有效的评估。8项版本准确地反映了基本结构。结论11项、8项和3项版的内隐认知量表具有较强的心理测量学性质，对观察到的成绩有相关效度证据。现代心理测量方法可以通过最大限度地提高每个项目的相关信息来帮助简化护理服务。
Objectives (1) To assess the 11-item Inner Effectiveness of Auditory Rehabilitation (Inner EAR) instrument with item response theory (IRT). (2) To determine whether the underlying latent ability could also be accurately represented by a subset of the items for use in high-volume clinical scenarios. (3) To determine whether the Inner EAR instrument correlates with pure tone thresholds and word recognition scores.Design IRT evaluation of prospective cohort data.Setting Tertiary care academic ambulatory otolaryngology clinic.Subjects and Methods Modern psychometric methods, including factor analysis and IRT, were used to assess unidimensionality and item properties. Regression methods were used to assess prediction of word recognition and pure tone audiometry scores.Results The Inner EAR scale is unidimensional, and items varied in their location and information. Information parameter estimates ranged from 1.63 to 4.52, with higher values indicating more useful items. The IRT model provided a basis for identifying 2 sets of items with relatively lower information parameters. Item information functions demonstrated which items added insubstantial value over and above other items and were removed in stages, creating a 8- and 3-item Inner EAR scale for more efficient assessment. The 8-item version accurately reflected the underlying construct. All versions correlated moderately with word recognition scores and pure tone averages.Conclusion The 11-, 8-, and 3-item versions of the Inner EAR scale have strong psychometric properties, and there is correlational validity evidence for the observed scores. Modern psychometric methods can help streamline care delivery by maximizing relevant information per item administered.
