Participants may quit your study at any time, and you may also drop participants when necessary. This section describes how to manage withdrawals, how to access reports on dropped participants, and how to configure a dropout survey to collect the reasons for withdrawal.

## Dropping Participants

You can remove participants from a study. This action immediately stops all data collection and removes the study from their app (you may need to reload participants’ devices after performing this action).

To drop a participant from the study:

1. Go to the **Participation page** on the researcher dashboard.

2. Select the participant.

3. Click on the **Drop from study** button.

4. Confirm your action.

## Participant Dropout

To leave a study, follow these steps:

1. Open the **Avicenna app**.

2. Go to the **study home page**.

3. On the **About Study** page, tap the **DROP OUT OF THE STUDY** button.

4. Confirm your decision.

5. After selecting **Yes** , Avicenna checks whether a [**Dropout Survey**](#p-2910-dropout-survey-3) is configured for the study:

> [!note]  
> When a participant leaves your study, either by dropping out themselves or by you removing them, data collection stops immediately. However, all data they have provided up to that point, along with their participation record, will be retained. The participant ID will still appear in the [list of your participants](https://forum.avicennaresearch.com/t/participation/1280), and their status will be marked as **Dropped**.

## Dropout Survey

You can create a **Dropout Survey** to collect information on why participants decide to leave your study. This survey is displayed immediately before a participant leaves the study.

To create a Dropout Survey, follow these steps:

1. Start by **creating a new activity**. For detailed instructions on creating activities, see [Accessing Activities](https://forum.avicennaresearch.com/t/activities/1237#p-2864-accessing-activities-1).

2. When selecting an activity type, choose **Dropout Survey**.

3. After providing a **Name** and **Description** , click **Create** to open the [**Activity Editor**](https://forum.avicennaresearch.com/t/activities/1237#p-2864-activity-editor-9).

4. On the **Content** page, add the questions you want participants to answer before leaving your study.

5. Go to the **Preview and Publish** page and [publish your survey](https://forum.avicennaresearch.com/t/surveys/1286#p-2913-publish-surveys-12).

## View and Export Dropout Survey Responses

You can [view](https://forum.avicennaresearch.com/t/view-responses/1287/1) or export responses to your Dropout Survey by going to the **Activity Responses** page.

## Rejoining the Study

Participants can rejoin your study at a later time. If they do, Avicenna will use their existing participation record.

- **If the participant dropped out voluntarily:** They can rejoin at any time before their original participation end time and continue where they left off. If their original end time has passed, the researcher must extend their participation period first.
- **If the participant was removed by the researcher:** They can rejoin only if the researcher extends their participation end time. Upon rejoining, they will continue from where they left off.
