目的：为了评估收敛和结构效度的物理治疗证据数据库（PEDro）规模用于评价随机试验在physicaltherapeutic.Study设计和设置的方法学质量：PEDro总评分和单项评分提取9,456物理治疗试验索引PEDro。收敛效度进行了测试比较PEDro总分与其他三个质量量表。结构效度进行了测试，通过回归的PEDro得分和个人项目得分与科学信息研究所的知识网的影响因素（IF）和SCImago期刊排名（SJR）的期刊中，其中trials.Results：收敛效度的测试显示与其他质量尺度的相关性，范围从0.31到0.69。PEDro总评分与IF和SJR呈弱相关但显著相关（P < 0.0001）。10个单项量表项目中的8个项目与IF.Conclusion显著相关：本研究提供了初步证据的聚合效度和结构效度的PEDro总分和8个单项量表项目的结构效度。(C)2010年爱思唯尔公司All rights reserved.
Objective: To evaluate the convergent and construct validity of the Physiotherapy Evidence Database (PEDro) scale used to rate the methodological quality of randomized trials in physiotherapy.Study Design and Setting: PEDro total scores and individual-item scores were extracted from 9,456 physiotherapy trials indexed on PEDro. Convergent validity was tested by comparing PEDro total scores with three other quality scales. Construct validity was tested by regressing the PEDro score and individual-item scores with the Institute for Scientific Information Web of Knowledge impact factors (IF) and SCImago journal rankings (SJR) for the journals in which the trials were published.Results: Testing of convergent validity revealed correlations with the other quality scales ranging from 0.31 to 0.69. The PEDro total score was weakly but significantly associated with IF and SJR (P < 0.0001). Eight of the 10 individual scale items that contribute to the PEDro total score were significantly associated with IF.Conclusion: This study provides preliminary evidence of the convergent and construct validity of the PEDro total score and the construct validity of eight individual scale items.
