Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Cannabis use disorders are common among young adults in psychiatric treatment. Unfortunately, cannabis use can result in deleterious consequences for those in treatment, including developing more severe psychopathology and poorer treatment outcomes. Brief, electronic interventions for cannabis use have been developed for young adults. An example of a frequently used brief electronic intervention for cannabis users is e-Toke. e-Toke can be completed on a computer, tablet or phone, and has been shown to improve motivation to engage in substance use treatment among college students. However, e-Toke is less useful in decreasing the actual frequency of cannabis use. Additionally, e-toke is not tailored to young adults in psychiatric treatment. In this study, the investigators will develop and test a text messaging intervention that can be easily added to the popular computerized intervention e-Toke. The research staff hope the intervention will improve motivation to decrease cannabis use, and decrease the frequency of cannabis use, among young adults in psychiatric outpatient treatment. The text messages will be developed by, and tailored to, young adults in psychiatric treatment and texts will address motivations and barriers to reducing cannabis use in the context of psychiatric disorders. If the text message intervention is found to be an effective addition to e-Toke, this approach can be tested in a larger study, and then disseminated to other young adults in psychiatric treatment.
