Maintaining participant engagement is essential in long-term studies. Sometimes, you may want to remind participants who have not been completing their activities regularly. Although Avicenna does not natively support automatic notifications based on completion rate, you can still achieve this manually using your exported session data, a simple spreadsheet formula, and a notification linked to an information activity.

## The Situation

You are conducting a study where regular participation is important for data quality. You have a large number of participants and want to motivate those whose completion rate falls below a specific threshold (for example, 50%) by sending them a friendly reminder.

You can do this in three parts:

- **Calculating** completion rates externally
- **Creating** a reminder activity with a notification
- **Scheduling** the notification for the identified participants

## What to Do

1. **Download the Session Data**

2. **Calculate the Completion Rate**

3. **Create the Reminder Activity**

4. **Create the Notification Template**

5. **Schedule the Reminder for Low-Compliance Participants**

## Pro Tips

- The solution above is best suited for managing notifications for a large number of participants at once.
- If you only have a small number of participants whose completion rate is below the threshold and you have already identified them, you can send a [one-off notification](https://forum.avicennaresearch.com/t/notifications/1277#p-2904-one-off-notifications-8) directly to those participants without using the full CSV workflow.
- The same approach can be used to detect other behaviors, such as canceled or missed surveys that expired before answering.
- You can adjust the threshold or the message based on your study design.
