Our ambitions for Open Science

Our ambition is that the research results of Leiden-CID are of value to improving the lives of youth. Therefore, in extension of our open science agenda for academia, we also make parts of our research accessible and transparent for society.

our vision on open science

Improving research quality through data sharing

With the digital transitions and advancements, scientists around the world are taking endeavors to improve their research through data sharing and collaboration. We are applying a number of these initiatives to the LCID project.

Some of these require specific adaptations for our project, which we will share and motivate on this platform. Moreover, our open science vision was one of the motivations for this website. We share materials, data, code and experiences for a number of reasons:

Accessible to a diverse group of researchers

We also want to make our research accessible for researchers with a variety of backgrounds, herewith appreciating diversity in training, talents and profiles. Therefore we will include tutorials on data processing and analysis that are accessible for researchers with different levels of programming expertises. We will also include practical guides that help to get access to our data and understand data collection and structure. Please let us know what you need and provide us your feedback on our discussion forum, so we can shape our tutorials in the best way.


First, we aim to be as transparent as possible by sharing all our protocols, meta-data, scripts and lessons learned. Not only does transparency help us to get peer feedback that will ultimately enhance our scientific work, transparency also facilitates reproducibility and replication.

Reducing costs and participant burden

In addition, transparency and re-use bolsters the value of the costly and time-consuming data collection. As such, this will decrease costs of novel data collection, as our protocols are fully available. Also, we will share data, with respect to the privacy of our participants. This will not only reduce financial and herewith scarce scientific resources, but even more importantly will reduce participant burden. We are above all grateful for our amazing participants that have shared so much of their time and life with us. Thus, to reach our aims, our participants including their privacy are our highest priority.

What steps do we take to reach our goals?

Increase transparency by sharing our research protocols, best practices and lessons learned.
Make our data open access (with respect to GDPR) and accessible for researchers with varying backgrounds by may 2023.
Share tutorials on data processing and analysis.
Increase findability through metadata platform that will be launched in 2023.
In our open science endeavors transparency, findability and accessibility are key.

Societal impact of our work

Citizen involvement

Our ambition is that the research results of Leiden-CID are of value to improving the lives of youth. Therefore, in extension of our open science agenda for academia, we also make parts of our research accessible and transparent for society.

One of the ways we do this is by citizen involvement, where we will include children and key figures in their lives, such as parents and teachers, in different steps of the research cycle.

Using citizen involvement and citizen science, we will enrich Leiden-CID outcomes with practical knowledge and ask questions that are relevant for society today and in the future.


In addition to citizen involvement, we also have many outreach projects to foster societal impact of the Leiden-CID study. This includes science communication in which we share our research findings in different ways with societal stakeholders, such as teachers, parents and policy makers.

We believe this is an important aspect of researcher practice and as such our researchers and staff are encouraged to develop skills for outreach activities.

What steps do we take to reach our goals?

Set up education programs, policy advice, infographics, videos, interviews, presentations and podcasts.
We will involve citizens in shaping new research questions and in interpreting our research findings.
We also conduct citizen science projects, in which citizens become scientists themselves and support research by collecting data.
We also share our research findings with children, using innovative and creative ways of reaching this age group.
Get feedback from research community on discussion platform.
Active science communication throughout the project.

Development matters | Leiden-CID study

This study was developed as one of four work packages of the overarching Consortium on Individual Development (CID).

CID is a large multidisciplinary collaboration that unites the best researchers on youth and development in the Netherlands.
