Adding New & Duplicating Project Arms

Did you complete all of the following?

 Added surveys 

 Added devices

 Built enrollment

If the answer to all of the above is 'yes', you are ready to create the different interventions via 'Study Arms'!  Before you can customize each arm of your project, you will need to add in the arms.

Navigate to the Study Arms tab of Manage Study.  

Part I: Add a New Arm

1. Click '+ New Arm' and name the arm. 
   1. Example: Lottery Incentive Arm 
      
      
      
      
2. Participants: Indicate how many participants of the total number of participants should go into this arm.
   
   
3. Auto-start?: Indicate if you would like the participant to be automatically started by WTH once they have completed all of the enrollment steps or if WTH should wait for the project team to manually start them from the profile or Manage Participants view.
   
   
4. Financial Incentives: Check the box if...

• Payments: Your participants will be paid any amount, such as an enrollment or survey completion payment. Payments must also be checked for any studies using lotteries.
  
  
• Lottery: Your study will have an arm with lottery incentives.  
  • Fixed Position: You create a lottery with a certain number of digits and people win if their numbers match in the exact order (the same digit occurring in the same position). You can set a prize for each possible number of matches.
    • Most commonly used lottery scheme with digit drawing 2 
    • Example:
      
  • Lotto: You pick the number of digits in a lottery and then what the prize would be for matching any number of those digits. Position does not matter
• Example: 
  
• Number of digits: You set the number of digits the lottery. This applies to both the participant-chosen lottery numbers, and the selected winning numbers. Lotteries must be at least 1 digit. Most lotteries will likely be 2 or 3 digits.
  
  
•  Note: Only one type of lottery can be added per arm 

Medication Tools: 

• Medication Reminders: Reminders will show up on the participant dashboard, at which time they can specify when and how they would like to receive the reminder.  It can also be edited from the backend by an RC in the participant profile.  This allows participants to have different preferences for notifications vs. medication reminders. 
  
  • WARNING  This is an outdated feature that is no longer supported.  Want to send medication reminders at participant specific times? See Per Participant Scheduling for help! 
    
    
• Medication Names: Used to track relevant medications that your participants are taking for a medication adherence study.  By choosing this and selecting the number of medications, a tab will appears on each participant's profile
  
  
  

Other Options:

• • Participant Partners: Can log in to the website. They are full users, typically in a separate 'Partner' study.  Should be used if you need the partner to interact with the study site (e.g. consent, completing surveys, or viewing a dashboard).
    • Need to select which study the partners will be linked to.  If you don't see your partner study listed, contact the WTH Project Manager to add a new study for your partners.  
      
      
      
  • Support Partners: Can't log into or interact with the website. They are better thought of as secondary contact methods for the participant. Support partners are often used to notify about a participant's non-adherence or to alert the partner that the end of the study is nearing.  Feedback for support partners is built at the arm encounter level, which is addressed in the Building Study Arms with Encounters section. 
    • Indicate how many support partners a participant can have. By selecting this box, a tab will appear in the participant's profile in which you can enter in relevant information on the partner. 
      
      
      

5. Click the 'Add' button to add your new arm. 

Part II: Duplicate an Arm 

• Are the arms of your project similar? Do they have the same/similar messages, surveys, device uploads, etc? If so, reduce your build time by duplicating the arm! 
  • From there you can update, remove, or add the encounters to customize the arm for it's specific intervention. 

1. To copy the first arm, click the 'Duplicate' button. 
   
   
   
2.  Rename the duplicated arm and click the 'Duplicate' button. 
   1. Example: Rename Arm 1 (copy) to Arm 2 
      
      
      
3. You should now see the original arm (Arm 1) and the exact copy (Arm 2).  The arms will be identical. 
   
   
4. Now you are ready to make changes to Arm 2 to make it different than Arm 1 based on the project protocol design. 
   1. Remember to:
      1. Remove encounters that shouldn't be in Arm 2
      2. Add encounters that weren't in Arm 1 and should be in Arm 2 
      3. Swap out surveys, if needed
      4. Update feedback on encounters, if needed 
         1. e.g. you don't want to mention a payment to a participant in the control arm! 
            
            
5. Yay! Think of how much time that you just saved!
