Nowadays, the confronting dichotomous view between experimental/quasi-experimental and non-experimental/ethnographic studies still exists but, despite the extensive use of non-experimental/ethnographic studies, the most systematic work on methodological quality has been developed based on experimental and quasi-experimental studies. This hinders evaluators and planners' practice of empirical program evaluation, a sphere in which the distinction between types of study is changing continually and is less clear.
Based on the classical validity framework of experimental/quasi-experimental studies, we carry out a review of the literature in order to analyze the convergence of design elements in methodological quality in primary studies in systematic reviews and ethnographic research.
We specify the relevant design elements that should be taken into account in order to improve validity and generalization in program evaluation practice in different methodologies from a practical methodological and complementary view.
We recommend ways to improve design elements so as to enhance validity and generalization in program evaluation practice.
如今，实验性/准实验性研究与非实验性/人种志研究之间的二元对立观点仍然存在，尽管非实验性/人种志研究被广泛应用，但关于方法学质量的最系统的工作却是基于实验性和准实验性研究开展的。这阻碍了评估者和规划者进行实证项目评估的实践，在这个领域中，研究类型之间的区别正在不断变化且愈发模糊。
基于实验性/准实验性研究的经典效度框架，我们对文献进行综述，以分析系统评价和人种志研究中初步研究在方法学质量方面设计要素的趋同性。
我们从实用的方法学和互补的视角明确了在不同方法中，为提高项目评估实践的效度和普遍性而应考虑的相关设计要素。
我们推荐了改进设计要素的方法，以提高项目评估实践中的效度和普遍性。
