A subset of participants will also enroll in a Deep Phenotyping Cohort, which includes enhanced clinical and cognitive assessments and multimodal neuroimaging to investigate neurobiological mechanisms underlying MMHC and identify potential biomarkers of illness complexity and progression. In the near future, we aim to add to the current protocol to embed both a clinical trials network for youth mental health in Ontario and Calgary within the CALM study and add digital phenotyping using wearable technology to generate digital and physiological markers of MMHC. The current protoco…
