For all of the Way to Health veterans out there, remember the days when the development team had to custom build your study's target generators for you? Well look no further, YOU now have the ability to configure the target generator for your study! 

What is the Study Arm Target Generator? 

• Calculates a standard target or goal for all participants assigned to a given arm 
  • This allows participants to have a set target that is consistent across an arm 
    •  Note: if needed, an individual's target can be modified in their profile 
  • Permits participants assigned to Arm A to have a different goal than participants assigned to Arm B
    
    
• Ability to set different goal parameters including
  • Set goal value
  • Define start date and end date of target 

How do I set up the Study Arm Target Generator? 

1. Navigate to the 'Target Configurations' section of Manage Study.

1. • Data Source: Select the device that the target should look at. 
     • Haven't set up your devices yet? Go to the 'Devices' section of Manage Study. 
       
       
   • Data Field: Select the data that the target should look at. This should be the same selection field that is set up in the Device Settings. 
     • Example: Fitbit = steps, Withings Scale = weight 
       
       
   • Arm: Choose the arm that will have this target generator.  This allows you to have different criteria across arms.  
     • Want the same target for both Intervention and Control? Just created the same target generator twice, swapping out the arm! 
     • Haven't built the study arms yet? Go to 'Study Arms' section of Manage Study
       
       
   • Starting value: Choose the default goal value for all participants assigned to this arm. 
     • Example: 7000 steps for a pedometer or 480 minutes for a sleep wearable 

Scheduling

• Start Day: Select the day that the target should start.  If you only have one target, this is typically at study start, or Day 0. 
  
  
• End Day: Select the day that the target should end. Again, if you only have one target for the study duration, this is typically the last day in the study. 
  • Tip! Want to create a target ramp up? You can do this with the scheduling feature! 
    • Example: Target runs from Day 0-29 and then the target increases on Day 30-59 and increases again Day 60-89.  You can achieve this by creating 3 different targets! 

Once you are done building your Study Arm target generator.  Click 'Save'.  The new target will now appear in your Target Configurations overview page.

 Now that you have the Target Generator built, you can use it in Study Arm event logic! For more on building events and adding logic, see Events by Type
