Which group is expected to identify barriers and enablers to the study's implementation?

The focus group is particularly suited for identifying barriers and enablers to the study's implementation because it involves a diverse representation of participants who can share their experiences, insights, and opinions regarding the implementation process. Focus groups facilitate open discussion and allow for the gathering of qualitative data that can highlight specific obstacles and supportive factors in real-world settings. This method encourages interaction among participants, which can reveal nuanced issues that may not surface in other evaluation formats.

The involvement of healthcare administration teams, policymakers, or veteran consultants might not yield as comprehensive or representative insights as a focus group. While these groups can provide valuable perspectives, their structure typically does not encourage the same level of discussion and personal experience sharing that characterizes a focus group. Therefore, the focus group is the most effective choice for understanding the complexities surrounding the implementation of a study.
