Active clinical trials for "Anxiety Disorders"

Health anxiety by proxy is defined as parents' obsessive worries about their child's health. It is a newly described phenomenon, where the parent has persistent and distressing fears that his or her child may suffer from a serious disease that is being overlooked. These intrusive thoughts may lead to excessive attention directed towards their child's body and a tendency to interpret natural bodily sensations as unnatural and abnormal. As a consequence, parents with health anxiety by proxy may repetitively perform bodily inspections of their child. Besides the stress related to worrying about your child's health, the condition can also cause frequent and unnecessary medical examinations of the child. As a possible consequence of this parental behavior, the child may be at risk of developing similar maladaptive illness behaviors, illness perceptions and illness worries. Currently, the phenomenon is widely overlooked and no treatment for health anxiety by proxy exists. The aim of the study is to test the feasibility and possible effect of an internet-based treatment program for health anxiety by proxy (iACT-by-proxy) using a single-case experimental design. Design The iACT-by-proxy is being tested in a single-case experimental design with multiple baselines. In a multiple baseline design the participants have different baseline lengths but the same intervention and follow-up period. The rationale behind the different baseline lengths is that it will be evident if target outcome measures change at intervention entry, but not during baseline. Thus the participants' baseline-period functions as their own control. Hypotheses Patients will report a significant decrease in selected self-report measures of health anxiety by proxy answered every other day when comparing the baseline period to the interven-tion period. Patient self-report measures of health anxiety by proxy, emotional distress, and illness perception and catastrophizing when the child has symptoms will have decreased after intervention. Participants Parents assessed with health anxiety by proxy with children under 18years. Recruitment Participants are assessed with health anxiety by proxy using the Health Anxiety by Proxy Scale (HAPYS).Participants self-refer to the project through the webpage www.helbredsangst.dk. After diagnostic video-interview they are included in the project.

Little is known about whether and how brief mindfulness therapies yield clinically beneficial effects. This gap exists despite the rapid growth of smartphone mindfulness applications and presence of mental health treatment gap. Specifically, no prior brief, smartphone mindfulness ecological momentary intervention (MEMI) has targeted generalized anxiety disorder (GAD). Moreover, although theories propose that mindfulness intervention can boost attentional control (AC), executive functioning (EF), perspective-taking, and social cognition skills they have largely gone untested. Thus, this randomized controlled trial (RCT) aims to address these gaps by assessing the efficacy of a 14-day smartphone mindfulness EMI (vs. placebo). Participants with GAD will be randomly assigned to either MEMI or self-monitoring placebo (SMP). Those in treatment will exercise multiple core mindfulness strategies (open monitoring, acceptance, attending to small moments, slowed rhythmic diaphragmatic breathing). Also, those in MEMI will be reminded before bedtime that mindfulness is a lifelong practice. Comparatively, participants assigned to SMP will only be prompted to practice self-monitoring. They will notice their thoughts, rate any distress associated with them, and will not be taught any mindfulness strategies. All prompts will occur 5 times a day, for 14 consecutive days. They will complete self-reports and neuropsychological assessments at pre-, post-, and 1-month follow-up. Multilevel modeling analyses will determine if treatment (vs. self-monitoring placebo (SMP)) produces substantially larger reductions in trait worry and negative perseverative cognitions as well as steeper increases in AC and EF (inhibition, set-shifting, working memory updating). In addition, the investigators hypothesized that MEMI (vs. SMP) would lead to greater increases in performance-based and self-reported trait mindfulness, empathy, and perspective taking. Findings will advance understanding of the efficacy of unguided, technology-assisted, brief mindfulness in a clinical sample.

The aim of this study is to assess the efficacy of electroencephalography (EEG) neurofeedback (NF) as an Add-on Treatment for the Anxiety disorder. Meanwhile, evaluate the effect of EEG-NF on cognitive function of Anxiety patients. Furthermore, the investigators will examine the changes in cortisol, gut microbiome and some biomarkers. The hypothesis of this study is that EEG-NF alleviate the anxiety symptoms and improve the cognitive function of Anxiety disorder patients with regulating attention response.

This study represents the first research program to assess the efficacy of transdiagnostic cognitive behavior therapy (T-CBT) delivered via internet for anxiety and depression in adolescents. The primary aim of the study was to implement the program AMTE (Aprende a Manejar tus Emociones [Learn to Manage Your Emotions]), an internet delivered T-CBT protocol designed to target both anxiety and depression symptoms and disorders (major depression disorder, dysthymic disorder, panic disorder, agoraphobia, generalized anxiety disorder, and social anxiety disorder) in adolescents, and to establish its preliminary efficacy on anxiety and depressive symptomatology. A secondary objective is to demonstrate its potential effect regarding: (a) transdiagnostic measures associated with etiology of emotional disorders including negative affect, anxiety sensitivity, and emotional avoidance, and (b) positive factors including satisfaction with life and positive affect. It is expected that the T-CBT condition will be more effective than the waitlist (WL) control group on the primary (anxiety and depression) and secondary (transdiagnostic and positive factors) outcome measures.

Objective: This protocol uses functional magnetic resonance imaging (fMRI) to examine neuro-cognitive correlates of pediatric and adult mood and anxiety disorders. The primary goal of the project is to document, in pediatric anxiety disorders and major depression, perturbations in brain systems mediating attention biases, fear conditioning, emotional memory, and response to various forms of motivational stimuli. As one secondary goal, the project measures the relationship between these factors and treatment response to either fluoxetine, a specific serotonin reuptake inhibitor (SSRI), cognitive behavioral therapy (CBT), or interpersonal psychotherapy (IPT). Another secondary goal examines similar associations in adults. Study Population: A total of 2530 children, adolescents, and adults will be recruited. Most subjects will not be able to complete all procedures. We seek to comprehensively study 150 juveniles with only a current anxiety disorder, 60 juveniles with current major depression, 150 juveniles with no psychiatric disorder, 100 adults with major depression, 60 adults with an anxiety disorder, and 150 adults with no psychiatric disorder. To achieve this, we are recruiting 2530 individuals. Design: Subjects will be tested using fMRI paradigms designed to examine brain regions engaged when processing motivationally salient stimuli, as assessed during attention, memory, social interaction, reward, and fear-conditioning paradigms. After these initial fMRI tests, subjects with depression or an anxiety disorder receive treatment. Treatment will comprise open treatment with either fluoxetine or CBT, augmented with computer-based attention retraining, delivered in a randomized-controlled design, with random assignment to either active or placebo attentiontraining regimens. Adolescent subjects then will be re-tested after eight-weeks using only the attention, memory, and conditioning paradigms. Outcome Measures: Prior imaging studies note that tasks requiring attention modulation, emotional memory, social interchange, and fear conditioning engage brain regions previously implicated in adult mood and anxiety disorders. These regions include most consistently the amygdala and ventral prefrontal cortex. Moreover, imaging studies of reward function implicate the striatum and prefrontal cortex in adult mood disorders. As a result, we hypothesize that attention, memory, social interaction, reward, and conditioning paradigms will engage the amygdala, ventral prefrontal cortex and striatum in both psychiatrically healthy and impaired subjects. Moreover, we hypothesize that these healthy and psychiatrically impaired groups will differ in the degree of engagement. Juvenile subjects also will be treated for eight-weeks, and a subset will be re-tested with fMRI. We predict that pre-treatment abnormalities in neural circuitry will predict response to treatment, such that increased amygdala and prefrontal activation will occur in individuals who show the strongest response to treatment. Moreover, we hypothesize that effective treatment will normalize abnormalities in attention and emotional memory, as manifest in fMRI.

This study investigates the short-term effects of the MindEase app on anxiety levels.

Lengthy wait times to access treatment for youth anxiety disorders is a critical issue. To help address this issue, investigators will pursue the following aims in N = 65 families on waitlists for outpatient youth anxiety psychosocial treatment. Aim 1 Pilot Phase: Develop and pilot a single session intervention (SSI) tailored for families on waitlists for outpatient psychosocial treatment for youth anxiety disorders. Investigators will pilot the single session intervention (SSI) with N = 5 families and use cognitive response interviewing to obtain data from parents and children, ensuring the content is understandable and accessible. The SSI will include psychoeducation on the cognitive behavioral conceptualization of anxiety, introduction to self-regulation strategies to manage physiological manifestations of anxiety, and cognitive restructuring of anxiogenic thoughts. The SSI will also involve parents and present strategies on how parents can support their children in managing anxious feelings and thoughts. Investigators will refine the SSI based on these data. Following the Pilot Phase, investigators will enroll an additional N = 60 families and randomize them to either the SSI (n = 30) or waitlist control (n = 30). Aim 2 Test Phase Acceptability, and Satisfaction: Examine acceptability of the refined SSI, as well as satisfaction with the SSI. Investigators hypothesize that users will find the module to be acceptable and will report high satisfaction. Aim 3 Test Phase Anxiety Outcomes: Demonstrate reductions in youth anxiety symptom severity. Investigators hypothesize that anxiety symptom severity and impairment will be significantly lower among youth who receive the refined SSI relative to youth on waitlist control. The main risk or discomfort from this research is that participants might feel uncomfortable answering questions about their behavior and feelings. Another possible risk is breach of confidentiality that could identify a participant as having elevated levels of anxiety. The benefits of this SSI would include increasing accessibility and scalability of treatment for youth anxiety disorders. Overall, this study will provide critically needed data to advance resource efficient treatment options for youth anxiety disorders.

The goal of this feasibility and pilot study is to investigate the feasibility and preliminary clinical effects of a new rule-based chatbot intervention for adolescents with anxiety symptoms. The main questions are: Is the intervention feasible for adolescents who are experiencing anxiety symptoms? How do the adolescents experience the use of the intervention? Does the intervention lead to a reduction in anxiety symptoms? Does the intervention lead to a clinically significant reliable improvement at functional level?

This research study is investigating use of a single dose of cannabidiol (CBD) to help manage anticipatory anxiety in participants with advanced breast cancer poised to undergo computed tomography (CT) or positron emission tomography (PET) to assess tumor burden. The name of the study drug(s) are: - Cannabidiol (CBD)

This study evaluates the effectiveness and cost-effectiveness of a therapy-assisted internet-based intervention in patients with ischemic heart disease and co-morbid depression and anxiety referred for cardiac rehabilitation. Half of the patients will receive the intervention and the other half usual care. We hypothesize that the intervention will lead to a reduction in patients' symptoms of depression and anxiety and be cost-effective.
