This work focuses on mixed-methods research (MMR) and is the 11th in a series exploring the importance of research design, statistical analysis, and epidemiologic methods as applied to nutrition and dietetics research. MMR research is an investigative technique that applies both quantitative and qualitative data. The purpose of this article is to define MMR; describe its history and nature; provide reasons for its use; describe and explain the six different MMR designs; describe sample selection; and provide guidance in data collection, analysis, and inference. MMR concepts are applied and integrated with nutrition-related scenarios in real-world research contexts and summary recommendations are provided.
这项工作聚焦于混合方法研究（MMR），是探索研究设计、统计分析以及应用于营养与饮食学研究的流行病学方法的重要性的系列文章中的第11篇。混合方法研究是一种运用定量和定性数据的调查技术。本文的目的是定义混合方法研究；描述其历史与本质；提供使用它的理由；描述并解释六种不同的混合方法研究设计；描述样本选择；并在数据收集、分析和推断方面提供指导。混合方法研究的概念在实际研究背景下应用于与营养相关的场景，并给出总结性建议。
