The Canadian Occupational Performance Measure (COPM) recognizes a significant clinical shift with a minimum two-point alteration post-intervention. However, there is sparse evidence supporting this criterion's clinical significance. To investigate and report minimal important change (MIC) and minimal detectable change (MDC) within the COPM in various populations. In May 2023, a search was conducted to locate studies that calculated MIC and MDC in the COPM using multiple databases. Studies were screened and extracted to assess bias risk in the final article selections. After screening 229 included studies, five studies were selected; four studies calculated MIC (performance: 0.20-3.20 points, satisfaction: 1.45-3.20 points) and one study calculated MDC (performance: 1.47-3.14 points, satisfaction: 1.80-3.98 points) within the COPM. The study populations, reassessment periods, and risk of bias varied. To effectively use COPM's MIC and MDC as references, clients and intervention conditions must be considered.
加拿大职业表现测量量表（COPM）认可干预后至少两分的变化具有显著的临床意义。然而，支持这一标准临床意义的证据很少。目的是调查并报告不同人群中COPM的最小重要变化（MIC）和最小可检测变化（MDC）。2023年5月，通过多个数据库进行检索，以查找计算COPM中MIC和MDC的研究。对研究进行筛选和提取，以评估最终文章选择中的偏倚风险。在筛选了229项纳入研究后，选择了5项研究；4项研究计算了COPM中的MIC（表现：0.20 - 3.20分，满意度：1.45 - 3.20分），1项研究计算了COPM中的MDC（表现：1.47 - 3.14分，满意度：1.80 - 3.98分）。研究人群、重新评估期和偏倚风险各不相同。为了有效地将COPM的MIC和MDC用作参考，必须考虑服务对象和干预条件。
