Developmental Methodology
(DevM) Laboratory

Knowledge mobilization is about working together to share and apply research findings in ways that impact people’s lives.

We regularly publish our research in scientific journals and present at conferences. To reach a wider audience, we also share our work with the community through our Facebook and Instagram accounts:

• Facebook: Developmental Methodology Lab
• Instagram: @Labo_DevM_Lab

Additionally, we write blogs to discuss our research and its implications.

We explore how peers affect the emotional, behavioural, and social development of children and teenagers. Peer relationships greatly influence self-esteem and body image, which in turn impact mental health.

We investigate how parents shape the emotional and behavioural development of children and teenagers. Parental relationships and practices are crucial in forming children’s self-perception and body image, affecting overall mental health.

We research the role of schools and teachers to understand how they can prevent emotional, behavioural, and social issues in children and teenagers. School environments and teacher support are crucial for promoting a positive body image and academic engagement, which influence overall mental health.

We aim to understand how young people develop mental health issues, especially those related to body image dissatisfaction. Our research also looks into the effects of factors like the COVID-19 pandemic on self-image and well-being.
