A number of resources are available for evaluating the rigor of single-case designs, including the commonly used multiple baseline design. In this article, we discuss two characteristics commonly cited as necessary for the highest rigor in multiple baseline designs—concurrence and response-guided baseline condition duration. We suggest that both nonconcurrence and response-independent baseline condition duration may be appropriate in some situations. Suggestions for researchers include improved reporting and graphing. Future research is needed to determine experimental differences when these design variations are used.

重新思考多基线和多探头设计的严谨性

许多资源可用于评估单一案例设计的严谨性，包括常用的多基线设计。在本文中，我们讨论了通常被认为是多基线设计中最高严格性所必需的两个特征——并发和响应引导的基线条件持续时间。我们建议在某些情况下，非并发和独立于响应的基线条件持续时间可能是合适的。对研究人员的建议包括改进报告和图表。未来的研究需要确定使用这些设计变化时的实验差异。
