Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
In a single-blind randomised clinical trail with 75 patients with the diagnosis of schizophrenia, parents will be assigned to either FMI or to routine care. Assessments will be conducted at baseline and at a 10- and 22-month follow-up. The study hypothesis is that FMI will be more effective than routine care in reducing (a) cannabis use in patients and (b) distress and sense of burden in parents.
