Dimensional Brain Behavior Predictors of CBT Outcomes in Pediatric Anxiety (Anxiety-CBT)

December 4, 2021 updated by: Christopher Monk, University of Michigan
Anxiety is among the most prevalent, costly and disabling illnesses and tends emerge early in childhood. Cognitive behavioral therapy (CBT) is the first-line treatment for early life anxiety, but as many as 40% of young patients who receive CBT fail to get better. The proposed study will examine brain changes marking positive response to CBT for anxiety and how these changes may differ in children compared adolescents. By helping us to understand how CBT works, this study will pave the way for new treatments to stop anxiety early.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Impairing anxiety affects 33% of the population by adolescence and can become chronic, leading to depression, substance abuse, school-drop out and even suicide. To reduce anxiety and prevent its sequelae, patients must be effectively treated early; yet, the first line intervention, cognitive behavioral therapy (CBT), has a heterogeneous response with 40-60% of treated patients continuing to experience impairment from residual symptoms. The reasons for variability in CBT outcomes remain poorly understood, but individual (including developmental) differences in brain-behavioral targets of CBT may contribute. This proposal addresses two primary questions: 1) Do individual differences in CBT-relevant brain-behavioral functions lead to variation in CBT outcomes? and 2) Does development contribute to this variation? To answer these questions, this study will measure changes in brain and behavior markers of anxiety, before and after CBT, in children and adolescents across traditional, categorical anxiety disorders (e.g., social, generalized and separation anxiety disorders). Given that CBT facilitates control over fear to enable effective regulation, the investigators hypothesize that brain-behavioral markers of fear sensitivity, cognitive regulatory capacity and cognitive regulation of fear will predict and characterize mechanisms of CBT effect. In addition, the investigators hypothesize that these markers will differentially relate to CBT effect, depending on patient age.

Children and adolescents (7.0 - 17.99 years) with clinically impairing anxiety will be randomized to receive CBT or a relaxation control therapy for 12 weeks. Before and after therapy, all participants will receive an MRI scan to see what regions of the brain become active when emotion and concentration tasks are performed and how that activation is changed after CBT.

While the study itself is of parallel design for its data-collection and measurement purpose, it is listed as a partial-crossover design in the IRB-approved protocol because subjects randomized to the relaxation therapy are given the option of receiving 12-weeks of CBT sessions after the relaxation therapy data has been collected. Some limited data will be collected in patients who are initially randomized to relaxation therapy but then opt to crossover to CBT. MRI data will also be collected in healthy youth before and after 12 weeks (but without intervening therapy) to allow the investigators to control for the simple effects of time that may cause brain changes that are not related to therapy.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Brain function/structure as assessed by Magnetic Resonance Imaging scans
Time Frame: Baseline and 12-weeks
Pre- to post-CBT changes in functional, connectivity and structural MRI measures of brain networks relevant for anxiety. Brain regions include the amygdala, anterior insula, dorsal anterior cingulate cortex (dACC) and ventrolateral prefrontal cortex (vlPFC). Functional activation and connectivity of these brain regions are assessed using simple computer tasks performed during MRI scanning. Tasks engage threat reactivity, self-regulatory control and the interaction of these processes. Structural connections between regions will be measured using a MRI technique that measures water diffusion in the brain.
Baseline and 12-weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Pediatric Anxiety Rating Scale
Time Frame: weeks 0, 3, 6, 9, 12
The Pediatric Anxiety Rating Scale (PARS) is a clinician-administered assessment to rate the severity of anxiety symptoms associated with common DSM-V anxiety disorders (social phobia, separation anxiety disorder, and generalized anxiety disorder) in children. The investigators are looking for decreases in anxiety severity ratings from pre- to post-treatment.
