Questionnaire Questionnaire Set of pre-determined questions presented to study participants. Questionnaire.Structured Structured questionnaire Set of pre-determined questions, a great majority of which are closed-ended, although there may be a small proportion of open-ended questions. Questionnaire.Semistructured Semi-structured questionnaire Set of pre-determined questions, a significant proportion of which are open-ended (roughly one third to two thirds), and the rest are closed-ended.

There is more flexibility than in an unstructured questionnaire regarding which questions are asked of each participant and how they are conveyed. DataCollectionGuidelines Data collection guidelines Guidelines and directions that define the content of the data capture. Use a narrower term if possible. DataCollectionGuidelines.ObservationGuide Data collection guidelines: Observation guide Guidelines regarding what will be observed. Depending on the study design, an observation guide can be more or less structured, ranging from exact specifications and scales to loosely formulated ideas. 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.

DataCollectionGuidelines.SecondaryDataCollectionGuide Data collection guidelines: Secondary data collection guide Guidelines specifying what data are to be collected from previously existing sources originally created for other purposes. For example, directions on how to select and code data from qualitative sources to create a quantitative dataset. ParticipantTasks Participant tasks A description of tasks that participants are asked to carry out as a part of the data collection process. For example, marking places on a map, taking photographs, telling a fairy tale, etc. TechnicalInstruments Technical instrument(s) Instruments used to collect objective data like measurements, images, etc. For example, chronometers, scales, speedometers, blood pressure monitors, thermometers, x-ray machines, etc. ProgrammingScript Programming script Programming script written in a data query language that is used to extract specific data, for instance from online social networks. Other Other Use when the type of instrument is known, but not found in the list.
