Joint Effort (mobile application)

Experimental group

Description:

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.
