A Cannabis E-intervention for Young Cannabis Users With Early Psychosis (iCC)

iCC is a psychological app based intervention that will be delivered in form of up to 24 brief (10-15 minutes) interactive modules developed based on the principles of Motivational Interviewing (MI) and Cognitive Behavioural Therapy (CBT). During the intervention, participants will be offered MI and CBT-based activities (i.e., modules and strategies) aiming at facilitating change in cannabis use. At any point during the intervention, participants can reference modules that had been completed. Due to the frequency of behavioral stage changes in this population (e.g., regression in behavioral stage of change), stage of change will be monitored regularly throughout the intervention. During the follow-up period (i.e., Week 12-24), participants will have continuous access to the smart phone application and all built-in add-ons as described above. During this period, they will have access to 3 booster session.
