Main Project Settings
There are two data collection instrument types:
(1) Data entry by study team / admins = "Data Entry Forms"
(2) Data entry performed by subjects / study participants = "Survey"
For Surveys: If you plan to collect data directly from participants (ex: emailing questionnaires, posting survey to website, participant entering data on tablet / mobile device) then you must: (1) ENABLE the Main project settings > Use surveys in this project and (2) ENABLE the Online Designer page > “Enabled as survey” for each instrument you would like to collect as a survey.
There are two data collection formats:
(1) One record per patient = "Classic"
(2) One record per patient per event, with the possibility of defining multiple arms = "Longitudinal"
For Longitudinal Projects: you must ENABLE the Main project settings > Use longitudinal data collection with repeating forms
