Group Transdiagnostic Cognitive Behavioural Therapy for Intolerance of Uncertainty Versus Applied Relaxation

Many people find uncertainty distressing, but for some, it may become overwhelming and drive persistent anxiety, worry, and avoidance. This tendency is called intolerance of uncertainty (IU), and appears across many mental health conditions, including generalised anxiety, social anxiety, depression, and obsessive-compulsive disorder, which is why researchers describe it as a transdiagnostic feature. A type of therapy called Cognitive Behavioural Therapy for Intolerance of Uncertainty (CBT-IU) has been shown to reduce anxiety in previous trials. What remains to be known is how uncertainty changes when targeted directly, and whether the same mechanism applies across diagnoses. IU has mostly been measured using questionnaires, which indicate whether people find uncertainty difficult, but not what is actually happening when they encounter it. Recent research suggests that IU is not a single trait but a set of differences in how people estimate different kinds of uncertainty. Therefore, in addition to standard questionnaires, computer-based tasks will be used to explore an "uncertainty fingerprint" for each participant, capturing different aspects of uncertainty processing in a way that self-report measures cannot. In this study, the investigators are comparing CBT-IU, adapted to work across disorders, against Applied Relaxation. Applied relaxation is a well-established therapy that teaches people to notice and release physical tension but does not focus on uncertainty. Adults with high IU and anxiety symptoms (regardless of formal diagnosis) will be randomly allocated to one of the two 12-session group therapies. The investigators will measure anxiety and IU using standard questionnaires as the primary outcomes. Additionally, cognitive tasks will be used to measure the uncertainty fingerprint before therapy, immediately after, and three months later. The aim is to test whether reductions in IU are specific to CBT-IU rather than shared with an equally credible therapy that does not target uncertainty. Going beyond self-reports, the trial will then begin to resolve which specific aspects of uncertainty processing change, so that future treatments can be more precisely targeted and better matched to each person.

Ultra-brief Psychological Treatments for Emotional Symptoms and Disorders

The main objective of this randomized clinical trial is to study if various modalities of brief (eight sessions) and ultra-brief (four sessions) transdiagnostic cognitive-behavioral treatment work for decrease emotional symptoms and disorders, as well as to find out which emotional regulation processes and common factor of the intervention itself are involved in the therapeutic improvement. The investigators will compare the interventions of four groups: ultra-brief group treatment (1), brief group treatment (2), ultra-brief individual treatment (3) with the ultra-brief relaxation (control) group. The main questions the study aims to answer are: * Will the brief and ultra-brief treatment formats works better than the relaxation-based control group? * Will results obtained between the brief group therapy group and the ultra-brief group therapy group be similar? * Will the individual ultra brief therapy be more effective than the two group therapies because of common factors, such as the therapeutic alliance? * Will group therapies be more beneficial for cost and in terms of capability to reduce emocional symptoms than individual therapy? Participants will be randomly assigned to each of the groups and will receive the corresponding treatment, with different number of sessions. They will answer a series of questionnaires at the beginning and at the end of the intervention, as well as 3 months and 6 months after the end of the treatment.

Internet-delivered Cognitive-Behavioral Therapy for Adolescents With Autism and Anxiety

Anxiety is very common in autistic youth. Cognitive behavioral therapy (CBT) is the recommended treatment for both autistic and typically-developing (TD) youth with anxiety, yet most families cannot access CBT due to cost, practicalities of attending in-person treatment sessions, and a shortage of trained providers, especially in rural areas. The goal of this project is to increase access to care for families of autistic adolescents with anxiety through an internet-based treatment model.

Evaluation of Family-Based Behavioral Treatments for Youth With Anxiety and Obsessive-Compulsive Disorder

Anxiety and obsessive-compulsive disorders are among the most common in children. Although cognitive behavioral therapy (CBT) is an effective and evidence-based treatment for such disorders, access to CBT is often limited. Family-based and internet-delivered therapy is one method to increase access to care. The purpose of this project is to evaluate the comparative efficacy and treatment mechanisms of two lower-intensity but effective treatments for families of children with anxiety or obsessive compulsive disorder (OCD) via telehealth compared to an adapted Relaxation and Mentorship Training (RMT) intervention involving breathing exercises with a therapist.

Effects and Mechanisms of Change of Internet Delivered Cognitive Behavior Therapy for Generalized Anxiety Disorder

The goal of this clinical trial is to compare two psychological treatments for Generalized Anxiety Disorder. The main questions it aims to answer are: How well do these treatments work compared to earlier studies? Is one of the treatments more effective than the other? Are the treatments working the way that we think they do? Specifically, do changes in the variables that these treatments aim to target predict changes in anxiety symptoms? Participants will be randomized to two different internet-based cognitive behavioral therapy (ICBT) programs: Intolerance of uncertainty-based ICBT and metacognition-based ICBT. Both programs consist of 8 treatment modules and run for 10 weeks. A psychologist will respond to the participants assignments and exercises and will respond to messages.

Qualitative Study of Student Financial Insecurity and Psychiatry

Since the COVID-19 pandemic, mental health disorders have increased significantly, particularly among young people. In France, the proportion of young people aged 18 to 25 suffering from depression almost doubled between 2017 and 2021. This phenomenon particularly affects students, who are already identified as being at greater risk of mental health disorders than the general population. Medical students seem to be particularly vulnerable: in 2021, a national study showed very high rates of depression and suicidal thoughts in this population. The main factor associated with depression was the feeling of financial hardship. Students often face multiple forms of insecurity. Financially, they have limited resources and struggle to cover their basic needs such as housing, food and healthcare. Socially, many experience significant isolation, particularly when they are away from their families or under pressure from their studies. All of this has a significant impact on their mental health. Unfortunately, many students do not seek help due to lack of time, resources, or awareness of support services. The 2021 study showed that only one-third of medical students suffering from depression received appropriate treatment. The aim of the study is to explore the lived experiences of the students concerned in order to identify what they perceive as the various aspects of student precarity (housing, transport, isolation, financial difficulties, etc.) and the links they perceive between these and their psychological distress. This study will deepen our understanding of these factors by exploring students' lived experiences, and will bring to light elements not identified by quantitative studies.

Testing Delivery Modalities of Team-Based CBT for Pediatric Anxiety in Community Health Settings.

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., social worker) who also provides weekly supervision for the exposure coach. 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.
