Research protocol for a randomized controlled trial of Keep it Real, a web-based program for cannabis use and psychotic experiences in young people
ABSTRACT
Background:
Young Australians (16-25 years) have some of the highest rates of past month cannabis use in the world. Cannabis use increases the risk of alcohol and other drug disorders, depressive disorders and has a robust dose-response association with psychotic experiences (PEs) and disorders. PEs are subthreshold positive psychotic symptoms, including delusions and hallucinations, which increase the risk of substance use, depressive or anxiety disorders, and psychotic disorders. Access to effective web-based early interventions targeting both cannabis use and PEs could reduce such risk in young people.
Objective:
To determine the efficacy and cost-effectiveness of the Keep it Real web-based program, compared to an information only control website among young cannabis users (16-25 years) with PEs.
Methods:
Participants are randomized to either the Keep it Real web-based program (n=249), or an information-only control website (n=249) and followed up at 3, 6, 9, and 12 months post-baseline. Primary outcome measures are weekly cannabis use, PEs and the relative cost-effectiveness for quality-adjusted life years. Secondary outcomes include other substance use and related-problems, PE-related distress, cannabis intoxication experiences, severity of cannabis dependence, depression/anxiety symptoms, suicidality, mental wellbeing, and functioning.
Results:
Recruitment commenced in July 2018 and the results are expected to be submitted for publication in late 2020.
Conclusions:
This study protocol describes a large, randomized controlled trial of a new web-based program for young cannabis users experiencing PEs. If effective, the accessibility and scalability of Keep it Real could help reduce growing public health concerns about the significant social, economic and health impacts of cannabis use.
