Health-related quality of life (HRQoL) is widely used as an outcome measure in the evaluation of treatment interventions in patients with chronic obstructive pulmonary disease (COPD). In order to address challenges associated with existing fixed-length measures (e.g., too long to be used routinely, too short to ensure both content validity and reliability), a COPD-specific item bank (COPD-SIB) was developed.
Items were selected based on literature review and interviews with Dutch COPD patients, with a strong focus on both content validity and item comprehension. The psychometric quality of the item bank was evaluated using Mokken Scale Analysis and parametric Item Response Theory, using data of 666 COPD patients.
The final item bank contains 46 items that form a strong scale, tapping into eight important themes that were identified based on literature review and patient interviews: Coping with disease/symptoms, adaptability; Autonomy; Anxiety about the course/end-state of the disease, hopelessness; Positive psychological functioning; Situations triggering or enhancing breathing problems; Symptoms; Activity; Impact.
The 46-item COPD-SIB has good psychometric properties and content validity. Items are available in Dutch and English. The COPD-SIB can be used as a stand-alone instrument, or to inform computerised adaptive testing.
健康相关生活质量（HRQoL）在慢性阻塞性肺疾病（COPD）患者治疗干预评估中被广泛用作一项结果指标。为应对与现有固定长度测量方法相关的挑战（例如，太长无法常规使用，太短无法确保内容效度和信度），开发了特定于慢性阻塞性肺疾病的题库（COPD-SIB）。
基于文献综述和对荷兰COPD患者的访谈选择条目，重点关注内容效度和条目理解。使用莫肯量表分析和参数化项目反应理论，利用666例COPD患者的数据评估题库的心理测量质量。
最终的题库包含46个条目，形成一个强量表，涉及基于文献综述和患者访谈确定的八个重要主题：应对疾病/症状、适应性；自主性；对疾病进程/终末状态的焦虑、绝望；积极的心理功能；引发或加重呼吸问题的情况；症状；活动；影响。
46个条目的COPD-SIB具有良好的心理测量特性和内容效度。条目有荷兰语和英语版本。COPD-SIB可作为独立工具使用，或为计算机自适应测试提供信息。
