The Peabody Developmental Motor Scales-2 (PDMS-2) has been used to assess the gross and fine motor skills of children (0–6 years); however, the measurement properties of the PDMS-2 are inconclusive. Here, we aimed to systematically review the measurement properties of PDMS-2, and synthesize the quality of evidence using the Consensus-based Standards for the Selection of Health Measurements Instruments (COSMIN) methodology. Electronic databases, including PubMed, EMBASE, Web of Science, CINAHL and MEDLINE, were searched for relevant studies through January 2023; these studies used PDMS-2. The methodological quality of each study was assessed by the COSMIN risk-of-bias checklist, and the measurement properties of PDMS-2 were evaluated by the COSMIN quality criteria. Modified GRADE was used to evaluate the quality of the evidence. We included a total of 22 articles in the assessment. Among the assessed measurement properties, the content validity of PDMS-2 was found to be sufficient with moderate-quality evidence. The structural validity, internal consistency, test-retest reliability and interrater reliability of the PDMS-2 were sufficient for high-quality evidence, while the intrarater reliability was sufficient for moderate-quality evidence. Sufficient high-quality evidence was also found for the measurement error of PDMS-2. The overall construct validity of the PDMS-2 was sufficient but showed inconsistent quality of evidence. The responsiveness of PDMS-2 appears to be sufficient with low-quality evidence. Our findings demonstrate that the PDMS-2 has sufficient content validity, structural validity, internal consistency, reliability and measurement error with moderate to high-quality evidence. Therefore, PDMS-2 is graded as ‘A’ and can be used in motor development research and clinical settings.

应用 COSMIN 方法评估 Peabody 发育运动量表 2 的测量特性

Peabody 发育运动量表-2 (PDMS-2) 已用于评估儿童（0-6 岁）的粗大和精细运动技能；然而，PDMS-2 的测量特性尚无定论。在这里，我们的目的是系统地审查 PDMS-2 的测量特性，并使用基于共识的健康测量仪器选择标准 (COSMIN) 方法来综合证据质量。截至 2023 年 1 月，检索了包括 PubMed、EMBASE、Web of Science、CINAHL 和 MEDLINE 在内的电子数据库中的相关研究；这些研究使用PDMS-2。每项研究的方法学质量均通过 COSMIN 偏倚风险检查表进行评估，并通过 COSMIN 质量标准评估 PDMS-2 的测量特性。修改后的 GRADE 用于评估证据的质量。我们在评估中总共纳入了 22 篇文章。在评估的测量属性中，PDMS-2 的内容效度被发现足以提供中等质量的证据。 PDMS-2 的结构效度、内部一致性、重测信度和评估者间信度足以提供高质量证据，而评估者内信度足以提供中等质量证据。对于PDMS-2的测量误差也找到了足够的高质量证据。 PDMS-2 的整体结构有效性足够，但证据质量不一致。对于低质量的证据，PDMS-2 的响应能力似乎足够。我们的研究结果表明，PDMS-2 具有足够的内容效度、结构效度、内部一致性、可靠性和测量误差，并具有中等到高质量的证据。因此，PDMS-2 被评为“A”级，可用于运动发育研究和临床环境。
