How does participation work?

On the website www.slimmerzwangeronderzoek.nl//en/register, you can sign up for the online coaching program by filling in your details under 'register.' After signing up, one of the researchers will contact you by phone.

If you still want to participate after the phone call, you will receive an email requesting you to sign the consent form. Once you (and possibly your partner) have signed it, the researcher will register you as a participant in the study. You will then be randomly assigned to a group, and you will receive an email informing you of which group you are in.

If you are assigned to the intervention group, you can now download the app, and the program will begin!

Downloading the app

Go to the App Store (iPhone) or Google Play Store (Android).
Search for "Slimmer Zwanger" and download and install the app.
Open the app and log in with the email address and password you selected earlier.
The first time you log in, you must agree to the terms and conditions of Slimmer Zwanger.
Using the app Once logged in, you can immediately fill out the first lifestyle questionnaire, which takes about 5 minutes. Afterward, you will see the results screen, which shows areas where you can improve.

Is your partner also participating? You can invite your partner via the app. Click on the face icon at the top right of the app, then click "Invite partner." Your partner will receive an email and will need to download and install the app as well.
