The Canadian Occupational Performance Measure (COPM) is widely used in clinical practice and research. However, the measurement properties of the COPM were not reviewed using rigorous systematic methodology.
To evaluate the measurement properties of the COPM.
MEDLINE, Web of Science, Scopus, OTseeker, and Cochrane Library. Study Selection and Data Collection: We used the updated COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) Risk of Bias checklist to evaluate the measurement properties of the COPM reported in relevant studies.
Our search identified 35 articles that reported measurement properties for the COPM with samples that differed in age, country, diagnosis, and disease stage. For content validity, the evidence was inconsistent and of low quality; no studies assessed structural validity. For reliability, the internal consistency was indeterminate and of low quality. One study reported indeterminate and very low quality evidence for cross-cultural validity. According to the evidence reported in these studies, the COPM has inconsistent and moderate reliability, construct validity, and responsiveness and insufficient and high-quality evidence for criterion validity.
Our review of the evidence using the COSMIN Risk of Bias checklist indicates that the Canadian Occupational Performance Measure lacks high-quality validation. What This Article Adds: High-quality validation of the Canadian Occupational Performance Measure is lacking. Further examination of its measurement properties using updated relevant guidelines is required.
加拿大职业表现测量（COPM）在临床实践和研究中被广泛应用。然而，其测量特性并未采用严格的系统方法进行评估。
评估 COPM 的测量特性。
MEDLINE、Web of Science、Scopus、OTseeker 和 Cochrane Library。
我们使用经过更新的健康测量工具选择共识标准（COSMIN）偏倚风险检查表来评估相关研究中报告的 COPM 的测量特性。
我们的检索共确定了 35 篇报告了 COPM 测量特性的文章，这些文章的样本在年龄、国家、诊断和疾病阶段上存在差异。在内容有效性方面，证据不一致且质量较低；没有研究评估结构有效性。对于可靠性，内部一致性是不确定的，且质量较低。一项研究报告了跨文化有效性的不确定和极低质量的证据。根据这些研究报告的证据，COPM 的可靠性、结构有效性和反应性不一致且为中等水平，而其效标有效性的证据不足且质量较高。
我们使用 COSMIN 偏倚风险检查表对证据进行的审查表明，加拿大职业表现测量缺乏高质量的验证。这篇文章增加的内容：加拿大职业表现测量缺乏高质量的验证。需要使用更新的相关指南进一步检查其测量特性。
