The article provides an overview of the Nominal Group Technique (NGT) and the Delphi Technique, two consensus methods used in research for problem-solving, idea generation, or determining priorities. The NGT involves face-to-face discussions in small groups, typically involving four key stages: silent generation, round robin, clarification, and voting. The Delphi Technique, on the other hand, uses a multistage self-completed questionnaire with individual feedback to achieve consensus from a larger group of experts. The choice between the two methods depends on factors such as the research question, the required level of consensus, and practical considerations like time and geography. The NGT is suitable for exploring consumer and stakeholder views, while the Delphi Technique is commonly used for developing guidelines with health professionals. The article also discusses variations of both techniques and their applications in pharmacy research, emphasizing the importance of selecting the appropriate method based on the specific research context.The article provides an overview of the Nominal Group Technique (NGT) and the Delphi Technique, two consensus methods used in research for problem-solving, idea generation, or determining priorities.
