Activity chains are used when you want to require participants to complete activities in a specific order.
- New Chain - Click here to create a new activity chain
- Chain Editor
Name - Name your chain. This will not be seen by participants
Random Activity - Checking this box makes the activities inside of the chain rotate for each participant to eliminate order bias.
Assign - Select the segments to which it will be applied.
Once created, you attribute scheduled activities to the chain using the activity editor.
- Access the editor by clicking on the activity once it's been placed on the calendar.
- Inside the editor, attribute the activity to the chain using the "Assign this activity to" drop down menu.
- Once you've assigned your activities to the chain you can click "agenda" to see schedule for your chain. For randomized chain it allows you to see the order in which each participant will see the activities.
NOTE OF CAUTION
Launch Time - The system knows when to launch activity chains based on the time they are set to launch NOT based on the order they appear in the scheduler. To ensure your activities launch in your preferred order, time them incrementally. For example, if you had three activities launching on one day in a chain you would launch activity 1 at 8:00 am, activity 2 at 8:01 am, and activity 3 at 8:02 am.
Timing of Randomized Chains
While randomized chains will work for activities programmed across days, they can only randomize the activities that are available on any given day. So if you only have a single activity on a given day, there will be nothing for the system to randomize. As a result, make sure to have at least two activities per day when making a randomized chain.
