With the recognition of different population behavior and relevance of socio-cultural factors in health, health services and public health program contexts, qualitative research is increasingly being used in health research, including clinical trials. Qualitative research follows an inductive framework to explore and gain an in-depth understanding of the phenomena, especially why and how aspects, through techniques including interviews, focus groups and observations. It analyzes the textual data collected following one of the common analysis approaches: grounded theory, phenomenology, ethnography or participatory action research. Despite the divergence in principles, mixed methods research designs systematically combine the quantitative and qualitative methods for a comprehensive understanding on the issue. The commonly used mixed methods designs variably combine the purpose, priority, sequence, embedding and data integration. Mixed methods analysis requires strategic synthesis of the results to gain comprehensive knowledge for appropriate clinical or public health action.
随着人们认识到不同人群行为以及社会文化因素在健康、卫生服务和公共卫生项目背景中的相关性，定性研究在健康研究（包括临床试验）中的应用越来越广泛。定性研究遵循归纳框架，通过访谈、焦点小组和观察等技术，探索并深入理解现象，尤其是现象背后的原因和方式。它采用常见的分析方法之一（扎根理论、现象学、民族志或参与式行动研究）对收集到的文本数据进行分析。尽管原则上存在差异，但混合方法研究设计系统地结合了定量和定性方法，以全面理解问题。常用的混合方法设计以不同方式结合了目的、优先级、顺序、嵌入和数据整合。混合方法分析需要对结果进行策略性综合，以获取全面的知识，为适当的临床或公共卫生行动提供依据。
