Conditional relationships between items

Conditional relationships between items make it possible to design items in which a user both selects one or more options and provides additional information about the selected option or options. You can use conditional relationships for collecting:

For example, you can design an item that displays as a set of checkboxes nested within a radio group and includes text fields in which a user can type other information not covered by the existing options.

Illustration of conditional items

1 —First item contains Unknown/No/Yes codelist. 2 —Second item contains family members codelist. 3 —In the family members codelist, the text field is associated with the Other, specify codelist item.

Design tab of the Form Editor or Section Editor—Option descriptions

Option	Description
Repeating	Indicates that the form or section is repeating. Multiple instances of the same set of data appear in the form or section.
Common (forms only)	Indicates that the form is common. The same data is visible in all study events that contain the form.
Fixed (sections only)	Indicates that the section is a fixed repeating section containing static text that repeats for each instance of the item.
Keys (toolbar button and icon for repeating forms and sections only)	For a repeating form with no sections, opens the Keys dialog box, in which you can define key items. For a form with one or more repeating sections, displays a drop-down list of repeating sections. Selecting a section opens the Keys dialog box, in which you can define key items.
Fields
Codelist	Applies to text, float, and integer items only. Drop-down list with available codelists for the item. Available codelists are all of the codelists in the study or library with the same type as the item.
Conditional On	Title of the item on which the current item is conditional. The drop-down list in this column contains items that contain a codelist. If the current item is conditional on one of the items in this column, the current item provides additional data about one of the options in the codelist. For more information, see Conditional relationships between items.
Conditional Value	Code and label of the codelist item on which the current item is conditional.
Data Label
Description	Description of the item. The description can have 0-255 characters.
Display Override
Item Properties	Contains an Edit link, which you can click to open the Item Properties dialog box. If you navigate to the field using the Tab button, you can open the dialog box by pressing the spacebar.
Item Required	Indicates that the item is required.
Key	For key items, displays icons and numbers that indicate: Type of key item uniqueness (None, Individual, or Group). Order of the items in the drop-down navigation list that appears in the summary view of a repeating form in the InForm application. In the InForm application, key items are used to make it easier to navigate among the instances of a repeating form and to enforce data uniqueness in specific items.
Length	Applies to text, float, and integer items only. Length of the item. Allowed values: Text items—1 to 2000. Float items—1 to 18. Integer items—1 to 10.
Locked	Indicates that the item is locked.
MaxProperty	If a MaxValue is specified for the item, indicates whether the value can be less than or less than or equal to the MaxValue.
MaxValue	Maximum value that the InForm application will allow to be typed for the item.
MinProperty	If a MinValue is specified for the item, indicates whether the value can be greater than or greater than or equal to the MinValue.
MinValue	Minimum value that the InForm application will allow to be typed for the item.
Modified	Indicates that the item has been modified and has not yet been saved.
New	Indicates that the item is new and has not yet been saved.
Protected	Indicates that the item is protected.
Question	Default question for the item. This question appears on the form if no customized label or translation is defined for the item. The question can have 0-1000 characters. Certain words may be reserved for this field. For more information, see Reserved words for an item question or short question.
RefName	RefName of the item.
Revision	Revision number of the study object.
SDV Critical	Indicates that the study object is considered critical for source verification. If you select SDV Critical, SDV Required becomes selected as well.
SDV Required	Indicates that the study object must be source verified in the InForm application.
ShortQuestion	Text of a short version of the item question. In the InForm application, the short question appears as a column heading in a repeating form, an itemset, and in reports generated by the Reporting and Analysis application. The short question can have 0-255 characters. Certain words may be reserved for this field. For more information, see Reserved words for an item question or short question.
Special Fields	Type of special InForm field, or None, indicating that the item is not a special InForm field. Available special fields, along with the forms in which they appear, are: Initials (Screening). DOB (Screening). Screening date (Screening). Patient No. (Enrollment). Initials (Patient Identification. Completion status (Study Completion). Drop-out reason (Study Completion). DOV (Date of Visit). Randomization field (Randomization). For more information, see About special InForm forms.
Title	Title of the item. The title can have 1-63 characters.
Type	Item type; one of the following, or a custom item type defined in a library to which the study has access: Blood pressure Compound Date time Float Integer Text Yes No
Version	Version number of the study object. The version number is incremented only when a user explicitly updates it.

Note: To type extended ASCII characters in text fields, press ALT while entering the decimal code for the character. You can also add HTML formatting characters to a text field to control its appearance when deployed.
