Clinical Trial Summary

This a stepped wedged cluster RCT with two intervention arms--Treatment As Usual (TAU) and an Integrated Care Pathway (ICP). Eligible participants are between the ages of 13 and 18, who present to community mental health agencies with depressive symptoms as the primary concern. The primary objective is to establish the clinical effectiveness of the ICP intervention in the community setting relative to TAU, with respect to reducing evaluator-rated depressive symptoms. The secondary objectives are to explore changes in clinician-rated function and caregiver-rated symptoms for youth receiving the ICP intervention relative to TAU. The third objective is to explore the implementation effectiveness of the ICP intervention, namely investigating: feasibility, fidelity, cost and acceptability. Edited on March 7th, 2024: This is a quasi-experimental, multi-site cluster controlled clinical trial design with two intervention arms--Treatment As Usual (TAU) and an Integrated Care Pathway (ICP). Eligible participants are between the ages of 13 and 18, who present to community mental health agencies with depressive symptoms as the primary concern. The primary objective is to establish the clinical effectiveness of the ICP intervention in the community setting relative to TAU, with respect to reducing evaluator-rated depressive symptoms. The secondary objectives are to explore changes in clinician-rated function and caregiver-rated symptoms for youth receiving the ICP intervention relative to TAU. The third objective is to explore the implementation effectiveness of the ICP intervention in the community setting, namely investigating: feasibility, fidelity, cost and acceptability.


Description:

Background: Depression is the leading cause of disability in adolescents and a potent risk factor for adolescent suicide. Evidence-based treatments are available; however, many clinics do not provide guidelines-based treatments. Integrated Care Pathways (ICPs) are treatment algorithms based on the highest quality practice guidelines intended to facilitate the delivery of evidence-based treatment at the clinic level. Our group has already tested the feasibility of ICP for adolescent depression at an academic setting. There is still uncertainty regarding whether ICPs lead to improved outcomes in adolescent depression in community setting relative to typical care. Objective: The current study aim is to test the effectiveness of an ICP for depression in adolescents, called the CARIBOU-2 intervention, versus treatment-as-usual (TAU) in community settings. We hypothesize that participants receiving the ICP will show greater clinical improvement (in symptoms and functioning) than participants in TAU. This study will also examine important implementation outcomes. Method: The primary participants will be adolescents (N= 648), between the ages of 13 to 18 with depressive symptoms, presenting to one of six selected community mental health agencies. Through a stepped wedge design, all sites will begin in the TAU condition and transition to the ICP condition in a randomized sequence. The primary clinical outcome of interest is the difference between treatment groups in the rate of change of depressive symptoms from baseline to 24-week endpoint as measured by the Childhood Depression Rating Scale-Revised. Secondary outcomes include rate of change of functional improvement, as measured by the Children's Global Assessment Scale, and caregiver-rated internalizing symptoms as rated by the Childhood Behaviour Checklist. Generalized linear mixed-effects model is a proper choice to test our clinical hypotheses to control for covariates (e.g. demographics and baseline clinical measures), to accommodate multiple forms of the outcome (e.g. continuous, categorical and count type), and to account for clustering at individual level (for repeated measures) and at site level. Time, stage assignment and their interactions will serve as the primary predictors for the analyses. As an example, if we let Y_ijt to denote a continuous outcome of the j-th participant of the i-th site measured at time t, a linear model for Y_ijt will look like the following: Y_ijt=β_0+〖b_(0,ij)+b_(1,i)+β〗_1 t+β_2 〖Group〗_(i,t)+β_3 Group_it*t+〖β_4 X_ijt+ϵ〗_ijt of which 〖Group〗_(i,t) denotes the treatment assignment of the i-th site at time t, X_ijt, additional covariates, b_(0,ij) and b_(1,i), random effects at individual and site levels respectively, ϵ_( ijt), unexplained random error, and β's, regression coefficients. For sensitivity analyses, we will explore the use of quadratic or piecewise models when the linear model may not be adequate. We will adopt the intention-to-treat approach in general and use multiple imputation methods as the primary missing data strategy. Count data, proportions and qualitative data will be used to describe implementation outcomes. Relevance: Should our results be consistent with our hypotheses, systematic implementation of the CARIBOU-2 intervention to other community mental health agencies would be indicated.

Through a quasi-experimental, multi-site cluster controlled clinical trial design, sites will begin in the TAU condition and transition to the ICP condition once local enrollment to TAU has reached 25 participants. .

This study will also be examining the following implementation outcomes: feasibility, fidelity cost and acceptability. Generalized linear mixed-effects model will be the primary analytic tool for evaluating whether the CARIBOU-2 intervention is more effective than TAU for adolescents with depression presenting to care in the community with regards to improvement of depressive symptoms (Hypothesis A), self-reported functioning (Hypothesis B), caregiver-reported internalizing psychopathology (Hypothesis C), and suicidal ideation and behaviours (exploratory).

Outcome

Type Measure Description Time frame Safety issue
Primary Childhood Depression Rating Scale-Revised A 17-item measure rated by an RA following a semi-structured interview with the adolescent relating to symptoms of depression over the past 2 weeks. The RA will be blind to treatment assignment. Change from baseline to 24 weeks
Secondary Columbia Suicide Severity Rating Scale This measure contains items related self-injurious thoughts and behaviours. RAs rate 3 subscales: Suicidal Ideation Severity, Suicidal Behaviour (which includes suicide attempts and an item for non-suicidal self-injury that is recorded as distinct from suicidal behaviour), and Lethality. Change from baseline to 24 weeks
Secondary Depression Rating Scale This is an RA-rated 13-item subscale found in the Kiddie Schedule for Affective Disorders and Schizophrenia-Lifetime version used to assess for DSM-5 criteria of Major Depressive Disorder. Change from baseline to 24 weeks
Secondary Youth Quality of Life Scale Research Version This is a 41 item self-report scale measuring the broad array of constructs including sense of self-worth, quality of relationships, sense of agency and life satisfaction. Change from baseline to 24 weeks
Secondary Health and Social Service Utilization This is a 10-item, self-report questionnaire that collects data regarding services and medications used by the patient. Change from baseline to 24 weeks
Secondary Ontario Perception of Care Tool for Mental Health and Addictions Two versions of this tool were developed by CAMH (one for registered patients and one for family members of clients) and typically consists of 38 items on a Likert scale. It standardizes how substance use, mental health, and concurrent disorder services obtain client perception of care feedback. Change from baseline to 24 weeks
Secondary Adolescent Alcohol and Drug Involvement Scale Grid This scale is used for adolescent substance abuse frequency. It includes both alcohol and other drug abuse. Change from baseline to 24 weeks
Secondary Cognitive Behavioural Therapy Skills Questionnaire This 16-item measure utilizing a Likert scale from 1 (I don't do this) to 5 (I always do this) assess an individual's cognitive restructuring and behavioral activation skills. Change from baseline to 24 weeks
Secondary CollaboRATE This is a 3 item measure on a 5-point Likert Scale that measures the level of shared decision making in the clinical encounter from the patient's perspective, as part of assessing health care quality and provider performance. Change from baseline to 24 weeks
Secondary Nonsuicidal Self-Injury This measure comes from the Self-Injurious Thoughts and Behaviors Interview, which is a structured interview that assesses the presence, frequency, and characteristics of a wide range of self-injurious thoughts and behaviors, including suicidal ideation, suicide plans, suicide gestures, suicide attempts, and nonsuicidal self-injury (NSSI). The NSSI section has been adapted for the purposes of the study. Change from baseline to 24 weeks
