Calgary TYM Cohort (Trajectories in Youth Mental Health)


This study is a longitudinal study requiring your answers to questions about your mental health once a year, for up to 4 years. It helps our understanding of mental health trajectories in help-seeking youth by determining possible genetic and environmental risk factors for those with mental illness. We will ask for a saliva sample along with personal history, risk factors, symptom/outcome measures, and electronic health record data from consenting children, adolescents, teenagers and families looking for or accessing mental health services.
