Study Description: This study examines relations between neurocognitive and clinical features of pediatric anxiety disorders. The study uses neuro-cognitive tasks, functional magnetic resonance imaging (fMRI), as well as magneto- and electro-encephalography (M/EEG). Patients will be studied over one year, before and after receiving either one of two standard-of-care treatments: cognitive behavioral therapy (CBT) or fluoxetine, a serotonin reuptake inhibitor (SSRI). Healthy comparisons will be studied at comparable time points. Primary Objectives: To compare healthy youth and symptomatic, medication-free pediatric patients studied prior to receipt of treatment. The study seeks to detect relations between clinical features of anxiety disorders at baseline and a wide range of neurocognitive features associated with attention, memory, and response to motivational stimuli. Secondary Objectives: 1. To document relations between baseline neurocognitive features and response to Cognitive Behavioral Therapy (CBT) or fluoxetine, as defined by the Pediatric Anxiety Rating Scale (PARS) and Clinical Global Improvement (CGI) Scale. 2. To document relations between post-treatment changes in neurocognitive features and anxiety symptoms on the PARS following treatment with Cognitive Behavioral Therapy (CBT) or fluoxetine. 3. To document relations among broad arrays of clinical, cognitive, and neural measures Primary Endpoints: Indices of percent-signal change in hypothesized brain regions, comprising amygdala, striatum, and prefrontal cortex (PFC) for each fMRI and MEG paradigm. Secondary Endpoints: 1. Treatment-response as defined by a continuous measure, the Pediatric Anxiety Rating Scale score (PARS), and a categorial measure, the Clinical Global Improvement (CGI) score. 2. Levels of symptoms and behaviors evoked by tasks that engage attention, memory, and elicit responses to motivational stimuli. ...

Posttraumatic stress disorder (PTSD) can have significant impairment on aspects of mental well-being (MWB) including functioning, loneliness, physical health, and quality of life. There are several evidence-based treatments (EBPs) effective in treating PTSD such as Cognitive Processing Therapy (CPT) which is a specific type of cognitive behavioral therapy that has been proven effective in reducing symptoms of PTSD. However, there are several barriers (e.g., lack of providers, waitlists, costs, stigma, disabilities that complicate travel) that can prevent someone from engaging with these treatments. Recently, a self-help version of CPT was created to help address these barriers; but little research has been conducted to test its efficacy. Further, less is know about how a peer support program may augment improvements from participating in an EBP. The Women Veteran Network (WoVeN), a peer support program designed for women veterans, has a manualized 8-week program that directly targets MWB. It has been found to help foster belongingness and connectedness, particularly in those suffering from PTSD and depression. The present study aims to establish the feasibility, acceptability and tolerability of a scalable, sustainable, and effective treatment option for trauma survivors with subthreshold or full PTSD. The overarching goal is to understand the effectiveness of a self-help version of an EBP (either alone or in combination with a peer support program) in reducing PTSD symptoms while also helping improve mental well-being, reduce barriers, and increase access to quality care within health disparity populations.

Following adolescent concussion, poor sleep health is common and relates to the development of persisting post-concussion symptoms, and uninjured adolescents (independent of concussion) also commonly experience sleep insufficiency. Given the sparse guidance that exists for clinicians to provide evidence-based sleep health recommendations for adolescents with a concussion, the primary objectives of this prospective randomized clinical trial of adolescents with a recent concussion are to discover if a multidimensional and prescriptive sleep health intervention leads to: 1) faster symptom resolution time, better sleep quality, or longer sleep duration; and 2) improved sleep habits, mental health, or academic engagement, relative to standard-of-care post-concussion sleep health guidance. Findings from this research will provide the basis for more precise sleep health recommendations for adolescents who experience a concussion.

The purpose of this study is to test how the delivery of Cognitive Behavioral Therapy (CBT) for pediatric anxiety and OCD via different methods might increase its availability and effectiveness. CBT involves teaching the patient skills to enable them to gradually come into contact with feared situations. This process of gradually approaching feared situations is called exposure. Although CBT with exposure has the best evidence for treating anxiety disorders, not all children have equal access or respond the same way to CBT. As part of this study, patients will receive weekly CBT treatment sessions involving a combination of weekly visits with an exposure coach and one visit a month with a licensed provider (e.g., psychologist, social worker). This treatment will be delivered using one of three methods: 1) in-person (face-to-face sessions, occurring in the office and the home/community), or 2) telehealth (entirely remote sessions via web-based video conference), or 3) flexible (individualized mix of in-person and/or telehealth sessions). Eligible participants will be randomly assigned to one of these three methods. Results of this study will help determine which treatment method works best for whom. Treatment as described above will occur as part of care at partnering community care sites in Rhode Island. Providers from the following partnering community care sites will make up patient treatment teams: Blackstone Valley Community Health Care, Family Services of Rhode Island, Gateway Healthcare, Newport Mental Health, and Thrive Behavioral Health. The research study is being conducted by the Pediatric Anxiety Research Center at Brown University Health. The research team will conduct the study assessments that patients will be asked to participate in as study participants. Patients will be asked to complete assessments prior to starting treatment, at two time points during treatment, at the end of treatment, and at two timepoints 3 and 6 months following the end of treatment. Participants will be compensated for their time completing research assessments.
