Objective This study aimed to systematically review the psychometric properties of outcome measures that assess dysfunctional breathing (DB) in adults. Methods Studies on developing and evaluating measurement properties to assess DB were included. The study investigated the empirical research published between 1990 and February 2022, with an updated search in May 2023 in the Cochrane Library database of systematic reviews and the Cochrane Central Register of Controlled Trials, the Ovid Medline (full), the Ovid Excerta Medica Database, the Ovid allied and complementary medicines database, the Ebscohost Cumulative Index to Nursing and Allied Health Literature and the Physiotherapy Evidence Database. The included studies’ methodological quality was assessed using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) risk of bias checklist. Data analysis and synthesis followed the COSMIN methodology for reviews of outcome measurement instruments. Results Sixteen studies met the inclusion criteria, and 10 outcome measures were identified. The psychometric properties of these outcome measures were evaluated using COSMIN. The Nijmegen Questionnaire (NQ) is the only outcome measure with ‘sufficient’ ratings for content validity, internal consistency, reliability and construct validity. All other outcome measures did not report characteristics of content validity in the patients’ group. Discussion The NQ showed high-quality evidence for validity and reliability in assessing DB. Our review suggests that using NQ to evaluate DB in people with bronchial asthma and hyperventilation syndrome is helpful. Further evaluation of the psychometric properties is needed for the remaining outcome measures before considering them for clinical use. PROSPERO registration number CRD42021274960.

评估呼吸功能障碍结果测量的有效性和可靠性：系统评价

目的 本研究旨在系统回顾评估成人呼吸功能障碍 (DB) 的结果测量的心理测量特性。方法 包括开发和评估测量特性以评估 DB 的研究。该研究调查了 1990 年至 2022 年 2 月期间发表的实证研究，并于 2023 年 5 月在 Cochrane 图书馆系统评价数据库和 Cochrane 对照试验中央注册库、Ovid Medline（完整）、Ovid Excerta Medica 数据库、奥维德联合和补充药物数据库、Ebscohost 护理和联合健康文献累积索引以及物理治疗证据数据库。使用基于共识的健康测量仪器选择标准 (COSMIN) 偏倚风险检查表来评估纳入研究的方法学质量。数据分析和综合遵循 COSMIN 方法来审查结果测量工具。结果 16 项研究符合纳入标准，并确定了 10 项结果指标。使用 COSMIN 评估这些结果测量的心理测量特性。奈梅亨问卷 (NQ) 是唯一在内容有效性、内部一致性、可靠性和结构有效性方面具有“足够”评级的结果测量。所有其他结果测量均未报告患者组内容有效性的特征。讨论 NQ 显示了评估 DB 的有效性和可靠性的高质量证据。我们的综述表明，使用 NQ 来评估支气管哮喘和过度通气综合征患者的 DB 是有帮助的。在考虑将其用于临床之前，需要对其余结果测量的心理测量特性进行进一步评估。 PROSPERO 注册号 CRD42021274960。数据可在公共、开放访问存储库中获取。所有相关数据均可在。
