An interventional study of Cognitive Behavioral Therapy and Relaxation Therapy in Anxiety Disorders, Social Anxiety Disorder and Social Phobia, sponsored by University of Michigan. Completed at 1 site in United States. Open to participants aged 7 Years to 17 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2021-12-20.

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.
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.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Behavioral: Cognitive Behavioral Therapy
Behavioral: Relaxation Therapy
Healthy control participants, matched to gender and age with anxiety patients, will be enrolled. These healthy participants will be scanned with fMRI before and after \~16 weeks, but without any intervention (i.e., no therapy).
A therapy which teaches patients coping skills to manage anxiety and gradually yet repeatedly exposes patients to anxiety-provoking thoughts and situations until the anxiety habituates/diminishes.
Also known as: CBT
An active control therapy with minimal effects on anxiety symptoms. If randomized to this therapy, participants will have the option to cross-over to CBT once the relaxation therapy arms has been completed.
Brain function/structure as assessed by Magnetic Resonance Imaging scans
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.
Time frame: Baseline and 12-weeks
Pediatric Anxiety Rating Scale
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.
Time frame: weeks 0, 3, 6, 9, 12
Plan to share: Yes — Anonymized data will be shared with the National Database for Autism Research (NDAR) and the Research Domain Criteria Database (RDoCdb).
Ran from Dec 2016 to primary completion in Jul 2021, 55 months.
Of 3,836 non-industry interventional studies with no phase under Anxiety Disorders, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 28. This study's 55 months is above that.
Counting every sponsor, half of 3,938 studies reached it within 12 months; a quarter within 5 and three quarters within 28.
