Objective and accurate assessment of the degree of ocular motor nerve palsy is helpful not only in the evaluation of prognosis, but also for the screening of treatment methods. However, there is currently no comprehensive measure of its severity. In this study, we designed the Ocular Motor Nerve Palsy Scale and investigated its validity and reliability. Six experts were invited to grade and evaluate the scale. The study recruited 106 patients with a definite diagnosis of unilateral isolated ocular motor nerve palsy. Three physicians evaluated the patients using the scale. One of the three physicians evaluated the patients again after 24 hours. The content validity index（CVI） and factor analysis were used to analyze the scale＇s construct validity. The intraclass correlation coefficient and Cronbach＇s alpha were used to evaluate the inter-rater and test-retest reliability and the internal consistency. The CVI results（I-CVI = 1.0, S-CVI = 0.9, Pc = 0.016, K＊ = 1） indicated good content validity. Factor analysis extracted two common factors that accounted for 85.2% of the variance. Furthermore, the load value of each component was above 0.8, indicating good construct validity. The Ocular Motor Nerve Palsy Scale was found to be highly reliable, with an inter-rater reliability intraclass correlation coefficient of 0.965（P 0.01）, a test-retest reliability intraclass correlation coefficient of 0.976（P 0.01）, and Cronbach＇s alpha values of 0.63–0.70. In conclusion, the Ocular Motor Nerve Palsy Scale with good validity and reliability can be used to quantify the severity of ocular motor nerve palsy. This study was registered at Chinese Clinical Trial Registry（registration number： Chi CTR-OOC-17010702）.

Background:Lower limb burns can significantly delay recovery of *** lower limb functional outcomes is challenging in the unique burn patient population and necessitates the use of reliable and valid *** aims of this study were to examine the test-retest reliability,sensitivity,and internal consistency of Sections 1 and 3 of the Lower Limb Functional Index-10(LLFI-10)questionnaire for measuring functional ability in patients with lower limb burns over ***:Twenty-nine adult patients who had sustained a lower limb burn injury in the previous 12 months completed the test-retest procedure of the *** addition,the minimal detectable change(MDC)was calculated for Section 1 and 3 of the *** 1 is focused on the activity limitations experienced by patients with a lower limb disorder whereas Section 3 involves patients indicating their current percentage of pre-injury ***:Section 1 of the LLFI-10 demonstrated excellent test-retest reliability(intra-class correlation coefficient(ICC)0.98,95%CI 0.96–0.99)whilst Section 3 demonstrated high test-retest reliability(ICC 0.88,95%CI 0.79–0.94).MDC scores for Sections 1 and 3 were 1.27 points and 30.22%,*** consistency was demonstrated with a significant negative association(rs=?0.83)between Sections 1 and 3 of the LLFI-10(p<0.001).Conclusions:This study demonstrates that Section 1 and 3 of the LLFI-10 are reliable for measuring functional ability in patients who have sustained lower limb burns in the previous 12 months,and furthermore,Section 1 is sensitive to changes in patient function over time.

测验信度估计：从α系数到内部一致性信度

沿用经典的测验信度定义，简介了信度与α系数的关系以及α系数的局限。为了推荐替代α系数的信度估计方法，深入讨论了与α系数关系密切的同质性信度和内部一致性信度。在很一般的条件下，证明了α系数和同质性信度都不超过内部一致性信度，后者不超过测验信度，说明内部一致性信度比较接近测验信度。总结出一个测验信度分析流程，说明什么情况下α系数还有参考价值；什么情况下α系数不再适用，应当使用内部一致性信度（文献上也常称为合成信度）。提供了计算同质性信度和内部一致性信度的计算程序，一般的应用工作者可以直接套用。

关键词：信度 α系数同质性内部一致性合成信度 reliability coefficient α homogeneity internal consistency composite reliability

本文在内容上是《数据科学在社会经济领域应用的重心——兼评〈十字路口的统计学，谁来应对挑战〉》①的续篇，试图从更为一般性的角度进一步探讨“应用统计方法研究”相关的“学科规范”问题，即数理统计方法在社会经济领域应用过程中应该侧重做什么和怎样做，关键是为什么这样做。全文分为三个部分：研究的格局、研究的相关性和应用过程中的方法论研究。研究聚焦所面临的第一个选择是：偏理论，还是偏应用？这需要把握好研究的学科格局。进而对论题的聚焦则需要注重“研究的相关性”，否则实证就失去了其不可或缺的社会经济意义。要达成实证研究的“内在一致性”和“外在一致性”，统计学者应该充分发挥自己的专业优势，深入开展“统计应用方法研究”，其内涵便是本文试图概括阐述的，以便统计实证奠基于方法应用的“机理”。统计应用过程也需要方法论研究，这便是本文的核心观点（聚焦点）。

关键词：格局相关性方法论学科规范内在一致性外在一致性机理 paradigm relevance methodology discipline norms internal consistency external consistency mechanism
