Objectives

The research focus of our team is to understand and prevent mental health problems in youths.
We aim to:

  • Investigate the risk and protective factors of Mental, Neurological and Substance use (MNS) problems in young people using a lifespan perspective
  • Test the efficacy of strategies to prevent Mental, Neurological and Substance use problems and build resilience to stressors in youths / parents

Research areas

In the past five years the team has provided relevant evidences on the early contribution of the social environment and biological factors on youth mental health (cognition, externalizing behaviors, internalizing problems, ADHD and risk for suicide).

Team members have studied the modulation of biological factors by the social environment in relation to externalizing problems and ADHD and the relative contributions of genes and environment on the developmental course of the ADHD phenotype and suicide risk, from the peri-conceptional period to adolescence. Team members have also found that cytokine patterns in the cord blood is associated with childhood anxiety/depression symptoms.

Regarding interventions aiming at improving mental health, cognitive development and social outcomes, the team has shown the benefits of early non-parental care and evidenced the moderate efficacy of a multicomponent early intervention program on behavior, cognition and health, in an Irish sample. Team members have developped eHealth tools to be used for MNS in youths, particularly in students. These findings provide key elements to inform public policies and to tailor our experimental interventions.

Research of team members takes advantages of various cohorts including birth cohorts (ex: ELFE and ELDEQ) and young adult cohorts (iShare and CONFINS).
