What is an Enrollment Run-in variable? 

An Enrollment Run-in variable is the same thing as the Enrollment Run-In Target Generator, but with extra perks! These two features allow you to calculate a goal for a participant based on their baseline run-in period data so that they can have a realistic and attainable goal.

...

• Allow participant's to choose their own goal based on how they did in the run-in period via the Goal Selection survey
• Calculate ramp up needed to ease into new goals.  See Target Value Variable for setting up Ramp Up periods
• Notify participants about their baseline run-in average

...

 HOLD UP, WAIT A MINUTE: It's important to note that the Enrollment Run in variable cannot be used to create a target for a participant. Instead create a Study Arm Target and use the Target Value Variable.

In Messaging:

1. Navigate to Study Arms under Manage Study. Click 'Manage Event Schedule' for the arm that you want to add a message to the participant about their baseline value. 
   
   
2. Either create a new event or edit an existing event. You can include your new variable in messaging on event creation or in the logic screen. 
   1. Not sure how to set up the {{ baseline x 20% }} variable? See Formula Variable for help. 
      
      
      
      
3. When the participant receives this message, the variables will be replaced with their current target value and target value in 7 days. 
   
   
   
   
4. Click 'Save' Logic' 
   
   
5. WARNING If you change the name of your available after it has been added to a message or incident text box, it will NOT update, and you will need to manually update it.  Therefore once you create your variables and add them into messaging, we recommend keeping the original name. 

Allowing participants to choose their own goal:

Imagine the following scenario: A participant completes a 2-week run in period and has an average step count for those 2 weeks, e.g. 8,000 steps.  The participant is told their average and asked to pick a goal. The participant has an option to choose 33% higher than baseline or 40% higher than baseline.
