背景与目的随机对照试验（RCT）的方法学质量通常被用来评估治疗效果偏倚估计的风险。本系统评价的目的是确定用于评估医疗保健研究中RCT方法学质量的量表，并总结这些量表的内容、建设、发展和心理测量学特性。方法广泛的电子数据库搜索，沿着手动搜索，进行了105项相关研究。他们占21规模及其修改。大多数量表没有经过严格的开发或有效性和可靠性测试。Jadad量表提出了最好的有效性和可靠性证据，但是，其有效性的物理治疗trials没有得到支持。讨论和结论许多量表被用来评估随机对照试验的方法质量，但大多数这些量表还没有得到充分的发展，并没有得到充分的有效性和可靠性测试。一个有效的和可靠的规模评估的方法学质量的物理治疗试验需要开发。
Background and Purpose The methodological quality of randomized controlled trials (RCTs) is commonly evaluated in order to assess the risk of biased estimates of treatment effects. The purpose of this systematic review was to identify scales used to evaluate the methodological quality of RCTs in health care research and summarize the content, construction, development, and psychometric properties of these scales.Methods Extensive electronic database searches, along with a manual search, were performed.Results One hundred five relevant studies were identified. They accounted for 21 scales and their modifications. The majority of scales had not been rigorously developed or tested for validity and reliability. The Jadad Scale presented the best validity and reliability evidence; however, its validity for physical therapy trials has not been supported.Discussion and Conclusion Many scales are used to evaluate the methodological quality of RCTs, but most of these scales have not been adequately developed and have not been adequately tested for validity and reliability. A valid and reliable scale for the assessment of the methodological quality of physical therapy trials needs to be developed.
