Technology-based psychotherapeutic interventions for decreasing cannabis use in people with psychosis: a systematic review update (Preprint)

UNSTRUCTURED We updated our 2020 systematic review related to the role of technology-based psychological interventions (TBPIs) to decrease cannabis use in individuals with psychosis. Two quantitative studies showed promising results of internet or virtual reality-based psychological interventions that incorporate cognitive behavioral therapy, motivational interviewing and psychoeducation principles on cannabis use outcomes. A qualitative exploratory study provided an integrative synthesis of patient and clinician opinions pertaining to the use of psychological approaches and technology to tackle cannabis misuse in individuals with psychosis. More clinically tested TBPIs are needed as our comprehensive review shows that only 11 studies have been published so far.
