FAQ

What is CRONOS+?

CRONOS+ is part of the CRONOS study and consists of digital questionnaires asking pregnant women about their experiences with COVID-19. 

Please visit the website of the German Society for Perinatal Medicine for more information about the CRONOS study.

What is the goal of CRONOS+?

CRONOS+ aims to better understand the impact of COVID-19 on pregnant women and their newborn babies.

Our goal is to give affected women a voice by asking them directly about their experiences with COVID-19 during pregnancy. 

The results of the study will be used to improve treatment and counseling of pregnant women with COVID-19.

Who can participate in CRONOS+?

CRONOS+ is open to pregnant women over the age of 18 who tested positive for COVID-19 while pregnant.

Who organized CRONOS+?

CRONOS+ is conducted by Data4Life and the German Society for Perinatal Medicine (DGPM).

The DGPM is the oldest and by far the largest professional society for the interdisciplinary field of "perinatal medicine" (obstetrics/neonatology and neighboring fields) in the German-speaking world.

How is CRONOS+ funded?

CRONOS+ is funded by Data4Life, a nonprofit organization and initiative of the Hasso Plattner Foundation. Our goal is to help improve the treatment and counseling of pregnant women with COVID-19 by making this important data more accessible to research.

How can I participate in CRONOS+?

CRONOS+ is completely digital and involves answering simple health questions using your smartphone, tablet, or computer. 

If you are interested in participating in the study, you can register using the form on this page. Simply enter your name and email address. The study doctors will contact you by email.

What questions will be asked?

As part of the study, you will be asked to answer questions about your health. For example, we might ask about your experiences during the pregnancy and any concerns you have regarding the health and birth of your unborn child.

How much time does it take?

During the course of your pregnancy, we will email you 1 or 2 times per month to ask you to answer some questions in your Data4Life account. This will only take a few minutes.

The last questionnaire will appear 4 to 6 weeks after your calculated due date.

Will I be compensated for participating in the study?

Digital studies are a simple way to do something good and contribute to health research. With more data on the well-being of pregnant women who have COVID-19, we can improve the treatment and counseling of future patients. 

Since CRONOS+ requires minimal time and effort, we do not offer compensation for study participation. 

As a patient, you can share your valuable experience and make an important contribution.

What happens to my data? How secure is it?

All information in your Data4Life account is private and encrypted.

Before researchers see your answers to the eCOV questions, we remove all personal identifiers (e.g. name, email address, and telephone number). This step, called pseudonymization, makes data useful for research without disclosing your identity.

You can find more information about how we maximize the security of your data in our help center.

As soon as enough data is available, we will analyze it and publish the results in a peer reviewed journal.

What happens if I stop participating early?

Participating for the entire study term allows researchers to get a complete picture of your pregnancy and gain helpful insights on the mental health of pregnant women with COVID-19.

If you would like to drop out earlier, you're free to do so at any time. We will do our best to take your previous answers into account.

I already gave birth to my baby. Can I still participate in the study?

Unfortunately, we cannot accept any new mothers to the study who have already given birth.

The study focuses on collecting data on your emotional state and feelings prior to and at the birth of your child.

I don’t have COVID-19. Can I participate in the study?

Testing positive for COVID-19 is one of the requirements for study participation. If you have not had a positive antigen or PCR test result, then we cannot accept you to the study.

If you do not meet the requirements for this study, check out our eCOV study or other ongoing studies

I’m already vaccinated against COVID-19. Can I participate in the study?

Both unvaccinated and vaccinated women are welcome to join the study.

If you have further questions or technical problems, please visit our help center.
