One hundred forty-six participants were randomly allocated to 1 of 2 groups: Ca-CBT (experimental group) or standard cognitive behavioural therapy (CBT) (control group) in a 1:1 ratio.

The objective of this analysis was to provide a model for the planning and costing of IYS throughout Canada over a 15-year period.MethodsTo estimate resource allocation for IYS, we determined the number of hubs and hub staffing requirements by service level and jurisdiction, backbone support and infrastructure requirements by jurisdiction. A needs-based analytic framework for planning was employed to estimate the number of hubs required. The optimal mix of hub staffing requirements was determined based on prior literature. The costs of running each hub were estimated using publicly available data and internal documents from existing IYS agencies. Finally, the cost of setting up IYS hubs, IYS virtual care and respective backbone support throughout Canada was estimated and projected over 15 years and the cost-savings of IYS were calculated.ResultsAt maturity, it was estimated that 399 hubs-188 small, 43 medium, 168 large-across Canada would be required to address youth mental health and substance use needs. The cost of implementing IYS initiatives across Canada would vary between $4,349,126 (for less populous jurisdictions) and $248,950,524 (for more populous jurisdictions), for a total annual cost of $676,633,388 (excluding costs of infrastructure). It was estimated that the implementation of IYS hubs would lead to cost-savings of $2.1 billion annually and have the potential to be cost-effective.ConclusionThe implementation of IYS hubs can provide good value for money, in the form of high client satisfaction, earlier supports with improved youth outcomes and decreased health care costs.

We characterized longitudinal patterns of stimulant drug use in children diagnosed for ADHD and analyzed the mental health disorders leading to add-on therapy with antipsychotics.MethodThe study population comprised of children and adolescents (age: 0-19 years) in the province of British Columbia (BC), Canada, with at least one dispensing for any psychotropic drug between 1997 and 2017 (<i>N</i> = 144,825). BC health administrative databases were used to identify children with diagnosis for ADHD and dispensings for stimulant and antipsychotic drugs. Longitudinal patterns of drug use and diagnostic codes proximal to the add-on of antipsychotics were assessed.Results<i>We found that residence in rural regions and lack of child psychiatrists are significantly associated with higher rates of stimulant drug prescription in preschool and early school-age children. Residence in rural regions was also associated with a higher rate for the concomitant use of antipsychotics over the course of stimulant treatment. When comparing children starting stimulant therapy before the age of 6 with those starting therapy after 6 years,</i> we found an 82% increase in the likelihood of antipsychotic add-on in those starting stimulants at younger ages (HR: 1.82, 95% CI [1.63-2.04]). Moreover, children starting stimulant therapy before the age of 6 years had 3.57-fold higher rates of diagnostic codes for specific delays in development (ICD-9 315) in close proximity to the antipsychotic add-on.ConclusionsThe question remains whether the add-on of antipsychotics is a consequence of insufficient action of the stimulant in ADHD, or required to ameliorate the adverse effects of the stimulant drug.

Integrated treatment of two or more co-existing mental health and substance use disorders (i.e., concurrent disorders) is increasingly prevalent in real-world clinical settings.

Only peer-reviewed studies of interventions treating concurrent disorders (i.e., simultaneous treatment of two or more disorders) in youth (10-29 years old) were eligible. Two independent reviewers conducted screening and data extraction. Results were charted according to studies employing pharmacological and non-pharmacological interventions.ResultsThirty peer-reviewed studies were included, 19 (63.3%) were randomized controlled trials (RCTs). Most studies enrolled participants with an unspecified substance use disorder (n=17, 56.7%), while alcohol use was the primary substance use disorder in seven (23.3%) studies, followed by cannabis use disorder in six (20.0%) studies. Mood disorders (e.g., depression, dysthymia) were the most common concurrent mental health disorders comprising 15 (50%) studies, followed by nine (30.0%) studies of behavioural disorders (e.g., ADHD) and five (16.7%) studies of unspecified psychiatric disorders.

We examined cross-sectional associations between emotion dysregulation or CU traits and cortical thickness (anterior cingulate cortex [ACC] and insula) and amygdala volume at baseline. We then examined whether the pre-treatment brain-behaviour relationships were linked to reduction in conduct problems post-treatment.ResultsLower ACC and insula thickness as well as amygdala volume was associated with greater levels of emotion dysregulation and CU traits at baseline (pre-treatment, <i>r</i> = |0.36-0.61|).
