Joint Effort Study

Taking Action to Better Manage Cannabis Use Among Young Adults: Preliminary Evaluation of a Digital Tailored Prevention Tool With a Pilot Randomized Control Trial

This pilot randomized controlled trial (RCT) will be conducted to evaluate the acceptability and feasibility of a digital tailored prevention tool (i.e., the Joint Effort mobile application) aimed at supporting university-level students into taking action on their cannabis use. The two main objectives of the proposed study are:

1. To assess the acceptability of the Joint Effort mobile application in terms of uptake, engagement and intervention appreciation.
2. To document the feasibility of the study processes in terms of online recruitment rate, adherence to online data collection methods, and attrition rate.

Inclusion Criteria:

• active cannabis user (i.e., having used cannabis at least once in the past month)
• able to understand French
• own an iPhone (running on iOS 13 or higher).
