功能性神经影像资料的重测信度近来已成为一个备受讨论的话题。尽管早期相互矛盾的报告，收敛的报告，现在表明，重测信度是穷人的标准单变量测量，即体素和区域级的任务为基础的激活和边缘水平的功能连接。为了更好地理解这些最新研究的含义，需要理解通常由组内相关系数（ICC）测量的重测信度的细微差别。在这里，我们提供了一个指南的测量和解释的重测信度在功能神经影像学和审查的主要发现在文献中。我们强调的重要性，提高可靠性的选择，只要他们不降低有效性，指出的潜力，多变量的方法，提高两者。最后，我们讨论了在该领域正在进行的工作的背景下，最近的低重测信度报告的影响。
The test-retest reliability of functional neuroimaging data has recently been a topic of much discussion. Despite early conflicting reports, converging reports now suggest that test-retest reliability is poor for standard univariate measures—namely, voxel- and region-level task-based activation and edge-level functional connectivity. To better understand the implications of these recent studies requires understanding the nuances of test-retest reliability as commonly measured by the intraclass correlation coefficient (ICC). Here we provide a guide to the measurement and interpretation of test-retest reliability in functional neuroimaging and review major findings in the literature. We highlight the importance of making choices that improve reliability so long as they do not diminish validity, pointing to the potential of multivariate approaches that improve both. Finally, we discuss the implications of recent reports of low test-retest reliability in the context of ongoing work in the field.
