Value of the Code Descriptive Term of the Code Definition of the Code

DataCollectionGuidelines.DiscussionGuide Data collection guidelines: Discussion guide Guidelines for a group discussion. Depending on the study design, a discussion guide can be more or less structured, ranging from exactly formulated questions to general ideas on what to discuss.
