Creating a read only question
When a question is set as Read only this prevents the participant from answering or overwriting that question during an interview.
The read only property may be used where:
- the question is seeded with values from a participant database that you do not want the participant to change
- the question contains an initial value that is based on answers to previous questions in the survey that you do not want the participant to change
You can set a question as read only in the Variable Details or the Variable Properties windows. Note that the Read Only property is not available for Paradata or Note variables.
In the Variable Details window, the Read only field is selected to set the variable as read only and cleared to allow the variable to be edited. The Read Only field is shown when you click Toggle Definitions.
In the Variable Properties window, the Read only property is set to Yes to set the variable as read only or No to allow the variable to be edited.
