This method note presents Q methodology as a useful tool for evaluators to add to their practice toolbox. Q methodology, which involves both quantitative and qualitative techniques, can help researchers and evaluators systematically understand subjectivity and the communicability of opinions and perspectives. We first provide an overview of Q methodology, followed by a brief summary of how evaluators are using Q, and an explanation of the steps for implementing Q methodology. Either by itself or with other methods, the potential uses of Q methodology in evaluation are diverse. For practical demonstration, we describe how Q methodology was used in a recent evaluation in the UK to understand stakeholder subjectivity within the program. We then reflect upon the pros and cons of using Q in program evaluation, concluding that it constitutes a worthwhile tool for evaluating complex programs.

本方法说明将 Q 方法论作为评估人员添加到他们的实践工具箱中的有用工具。Q 方法论涉及定量和定性技术，可以帮助研究人员和评估人员系统地理解主观性以及意见和观点的可交流性。我们首先概述 Q 方法论，然后简要总结评估者如何使用 Q，并解释实施 Q 方法论的步骤。Q 方法本身或与其他方法一起，在评估中的潜在用途是多种多样的。为了实际演示，我们描述了最近在英国进行的评估中如何使用 Q 方法来理解项目中的利益相关者主观性。然后我们反思在程序评估中使用 Q 的利弊，
