The ARCH Lab has collaborated again with the COMPASS study on two recently published papers on the subject of substance use and mental health.

The first, “Cannabis Use, Screen Time, and Internalizing Symptoms among Canadian Youth: Testing Mediation Pathways” examines the factors that mediate the relationship between screen time sedentary behaviors (STSB), internalizing symptoms and substance use among youth. This study demonstrates that the associations are complex and involve mediation in both direction.

The second paper, “Substance use classes and symptoms of anxiety and depression among Canadian secondary school students” examines substance use classes among Canadian secondary school students and associations with anxiety and depression. Results show Canadian secondary school students are engaging in dual and poly-substance use, and anxiety and depression are associated with such use.
