Once you have created an Item Group in a Form, you can add Items to it.
You can create or import Items from within an Item Group view, in the Item References section.
Click the New Item in the Add menu. You will be taken to the Item-specific page, which allows you to define the following:
Item Basics
Sample-related settings
Data Validation Rules for the Item
Reporting fields
Item Basics
Prompt - this is an optional text that can be displayed to the users during data collection. If you leave this blank, the “Name” field from the Item Reporting section will be used.
Data Type - is arguably the most important field to configure for an Item. It determines how the user will be able to interact with the Item during data collection.
Code List - you can associate a predefined list of selectable answers to the users during data collection. The Code Lists can be defined in CRF Design > Study Library > Library menu > Code Lists. The datatype of the Item needs to match the datatype of the Code List.
Radio Buttons? - this is a control to display the possible answers as radio buttons (when ticked) or as a dropdown (when unticked).
Help Text - you can provide some optional help text that would help/guide the users during data collection.
Capture Time? - this setting allows to record the time entered in the datetime type of Item, as the time the Item was collected. Read more here. This will need to be enabled, if you are associating a Sample Processing Path with the Item.
Barcode Verify? - If you check this tickbox, users will need to scan an Item barcode in order to collect this Item. This will need to be enabled, if you are associating a Sample Processing Path with the Item.
Require External Barcode? - you can mark that the Item requires an external barcode when data is collected.
Measurement Units - you can add measurement units to the Item, if needed. Measurement units can be configured in the CRF Design > Study Library > Library menu > Measurement Units.
Label Field 1 / 2 - add some optional text which you can later use on Labels for the Item.
Base Type - If you are working on an Item that could be used in particular workflows, facilitated by Base Types, you can select the relevant Base Type for the Item here.
