Mixed methods research-i.e., research that draws on both qualitative and quantitative methods in varying configurations-is well suited to address the increasing complexity of public health problems and their solutions. This review focuses specifically on innovations in mixed methods evaluations of intervention, program or policy (i.e., practice) effectiveness, and implementation. The article begins with an overview of the structure, function, and process of different mixed methods designs and then provides illustrations of their use in effectiveness studies, implementation studies, and combined effectiveness-implementation hybrid studies. The article then examines four specific innovations: procedures for transforming (or "quantitizing") qualitative data, application of rapid assessment and analysis procedures in the context of mixed methods studies, development of measures to assess implementation outcomes, and strategies for conducting both random and purposive sampling, particularly in implementation-focused evaluation research. The article concludes with an assessment of challenges to integrating qualitative and quantitative data in evaluation research.

混合方法评估的创新。

混合方法研究，即利用定性和定量方法以不同配置进行研究，非常适合解决日益严重的公共卫生问题及其解决方案。这篇评论特别关注干预，计划或政策（即实践）有效性和实施的混合方法评估中的创新。本文首先概述了不同混合方法设计的结构，功能和过程，然后举例说明了它们在有效性研究，实施研究以及有效性与实施混合研究中的使用。然后，本文研究了四个特定的创新：转换（或“量化”）定性数据的过程，快速评估和分析程序在混合方法研究中的应用，评估实施结果的评估措施以及进行随机抽样和目的抽样的策略，尤其是在以实施为重点的评估研究中。本文最后评估了将定性和定量数据整合到评估研究中所面临的挑战。
