COMPASS is a 9-year (2012-2021) prospective cohort study that uses a hierarchical quasi-experimental design to evaluate how programs, policies, and built environments impact various youth health behaviours and outcomes (substance use [tobacco, e-cigarettes, alcohol, cannabis, opioids], mental health, obesity, diet, physical activity, screen time, sleep, bullying) over time.

Each year, COMPASS collects longitudinal data from ~70,000 grade 9-12 students and 120+ secondary schools across Canada (Ontario, Alberta, BC, Quebec, Nunavut).

Funded by CIHR, I led the development and testing of the COMPASS Mental Health Module – a research platform designed to evaluate the real-world effectiveness of school-based mental health interventions.

In 2018, I was awarded a 3-year CIHR Project Grant (with Co-PI Dr. Scott Leatherdale) for the longitudinal implementation of the mental health module within the COMPASS study.

The project aims to build capacity and provide infrastructure to continually improve programs, policies, and resources for the advancement of youth mental health. The new funding will provide up to 4 years of longitudinal data on youth mental health and relevant school program/policies (following ~70,000 students at 120+ schools across Canada over time), with the added value of being able to study mental health in relation to the other COMPASS domains (e.g., cannabis, physical activity, obesity).

Shaping the direction of youth health

The COMPASS system is a research platform for evaluating natural experiments and generating practice-based evidence in school-based prevention.
