Purpose Valid, reliable, and efficient patient-reported outcome measures are needed to quantify quality of life (QOL) outcomes after cochlear implantation to supplement information obtained from performance-based outcomes. We previously developed the Cochlear Implant Quality of Life (CIQOL) item bank to serve as the source of items for subsequent instruments. This study reports the development and psychometric properties for 2 of these new instruments, the CIQOL-35 Profile and the CIQOL-10 Global. Method Cochlear implant (CI) users referred from the CIQOL Development Consortium ( = 371), consisting of 20 CI centers across the United States, provided responses to the 81-item CIQOL item bank, which are grouped into 6 QOL domains (communication, emotional, entertainment, environment, listening effort, and social). Responses to the 81 CIQOL items were analyzed using item response theory to determine individual item difficulty, discrimination, and model fit to select the set of items for the profile instrument and global measure that would optimize their measurement characteristics. Results The 35-item CIQOL-35 Profile instrument assesses outcomes represented in the 6 domains of the CIQOL final item pool. The 10-item CIQOL-10 Global measure produces a single, overall QOL score. After ensuring the upper and lower ends of the item difficulty continuum were represented (item difficulty range: -2.48 to 2.47), the items with the highest discrimination ability for each domain were selected for the CIQOL-35 Profile instrument (discrimination range: 0.67-1.37). Items were selected for the CIQOL-10 Global measure in a similar manner. Conclusion The CIQOL-35 Profile and CIQOL-10 Global instruments provide psychometrically sound and efficient measures that can be used to assess QOL in adult CI users in both clinical and research settings.

需要有效的、可靠的和高效的患者报告结局测量工具来量化人工耳蜗植入后的生活质量（QOL）结局，以补充基于表现的结局所获得的信息。我们之前开发了人工耳蜗植入生活质量（CIQOL）项目库，作为后续工具项目的来源。本研究报告了其中 2 种新工具的开发和心理测量特性，即 CIQOL-35 简表和 CIQOL-10 全球量表。
来自美国 20 个人工耳蜗中心的人工耳蜗植入（CI）使用者（共 371 名）参与了 CIQOL 发展联盟，他们对包含 81 个项目的 CIQOL 项目库进行了回答，这些回答被分为 6 个 QOL 领域（沟通、情感、娱乐、环境、聆听努力和社交）。使用项目反应理论分析对 81 个 CIQOL 项目的回答，以确定每个项目的个体难度、区分度和模型拟合，从而选择能够优化测量特征的简表工具和全球量表的项目集。
包含 35 个项目的 CIQOL-35 简表工具评估了 CIQOL 最终项目库中 6 个领域的结果。包含 10 个项目的 CIQOL-10 全球量表则产生一个单一的整体 QOL 评分。在确保项目难度连续体的上下限都有代表（项目难度范围：-2.48 至 2.47）后，选择每个领域区分能力最高的项目纳入 CIQOL-35 简表工具（区分范围：0.67-1.37）。以类似的方式选择 CIQOL-10 全球量表的项目。
CIQOL-35 简表和 CIQOL-10 全球量表提供了具有心理测量学意义的有效测量工具，可用于评估临床和研究环境中成人人工耳蜗使用者的生活质量。
