Managing participants

Quick guide:

Subscribing participants

Step 1.


The subscription page can be found on the left, click on subscription. This will open the subscription page. Here you can find the general details button which shows you when the subscription phase will open and end. You can also find the URL for participants to register here.

In the informative pages you can add pages for ethical information or additional instructions. In the right under corner you can find a round + button, click on this to add a page. To make a thank you note click on the + button and select ‘This is a thank you page’

On the screening questions page you can add initial screening questions for your participants. The questions can be used to obtain initial information for your study which you can use to assign your participants to the appropriate intervention.

Step 2.


The emails page can be found in the left menu, click on emails. The emails page will allow you to draft template emails for your participants. For instance, once the study starts and if they are rejected from the study. This means that when you reject a participant from a study, the participant will immediately receive the rejection e-mail. The start study e-mail will be sent to your participant once you have assigned them to an intervention.

Note: This is the moment the participant is starting the study.

The email is sent by the BMSLab email account, yet the participant will see it as if the e-mail had been sent by the researcher who created the study. This will allow the participant to reply to the researcher.

Step 3.


The participant can subscribe online and fill in their details. Afterwards they will receive an email about their account. After the participant downloaded the app they are able to sign in with their account. TIIM is available on android and IOS devices.

Assigning Participants

Step 4.


The participants page can be found in the left menu, click on participants. The participants page displays a list of registered participants and will be sorted by the intervention they are assigned to.
When you click on an individual participant you will see detailed information on the participant and screening questions.

Assigning the participant to a particular Intervention will set the condition group they are in.  You can let the participant start when the intervention starts or on a custom date.

This tab also allows you to reject prospective Participants from the study.

The Screening tab will show their answers to the screening questions they answered when subscribing to the study. 

The Send Notification tab allows you to send specific push notifications to your Participant’s mobile phone. The push notification can work as a reminder, and to actively call for action to your participant. 

Note: the participant will receive the notification on their mobile phone, therefore this option is only available after they have installed and logged in on the app.
