JointEffort Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Joint Effort (mobile application)Experimental Treatment1 Intervention
The Joint Effort mobile application aims to support young adults into taking action on their cannabis use. Based on the Theory of Planned Behaviour, the content focuses on intention, attitude and perceived behavioral control. Various intervention methods and strategies are used to address these determinants (e.g., personalized feedback, persuasive communication, self-observation and activation of intention). The objectives includes: to allow the individual to become aware (or more aware) of their cannabis use, to support the individual's decision-making process of taking action on their cannabis use, to guide and support the establishment and sustainability of an action plan. An optional logbook-type feature (weekly journal of cannabis use) allows personalized monitoring and data collection throughout the course of the intervention.
Group II: Brief normative feedback and standard informationActive Control1 Intervention
The comparator is composed of a a brief normative feedback regarding last month frequency of cannabis use and basic reliable non personalized information on lower-risk cannabis use (official public websites).
