Filter by:The present study seeks to evaluate the clinical utility of repeated transcranial alternating current stimulation (tACS) by assessing long-term, lasting changes in oscillatory activity and subsequent changes in related behavioral processes of anxious arousal and sensory sensitivity. To date, only transient effects of tACS have been reported, lasting no longer than 30 to 70 minutes. In order to be truly impactful within a clinical setting, however, evidence for long-term effects of tACS is needed.
Up to one-half of those in treatment for alcohol use disorder (AUD) has a co-occurring anxiety disorder ("comorbidity"), a condition that marks a high degree of treatment resistance, severity and relapse risk in AUD treatment patients. The investigators conceptualize comorbidity as a feed-forward system ("vicious cycle", [VC]) of interacting negative affect/stress, drinking motives/behavior, coping skills deficits, environmental circumstances, and neurobiological adaptations. Based on this model, the investigators developed and validated the VC cognitive-behavioral therapy (VC-CBT) to disrupt this system at several key linkage points. In a recently completed randomized controlled trial (RCT), the investigators found that adding the VC-CBT to standard AUD inpatient treatment resulted in better alcohol outcomes 4 months following treatment than did adding an anxiety treatment or standard AUD treatment alone. With a number needed to treat (NNT) index of 8 (relative to standard AUD treatment alone), the VC-CBT could, if broadly disseminated, have a large positive impact on AUD treatment. Unfortunately, several significant barriers related to the resource- and expertise-intensive delivery of the VC-CBT limit its dissemination potential and, hence, the impact of this otherwise effective treatment. Therefore, to maximize the public health and scientific potential of the investigators work, the investigators propose to adapt the therapist-delivered VC-CBT to a computer-delivered format to facilitate reliable and economical dissemination of the VC-CBT while maintaining its established efficacy.
The goal of this study is to compare the efficacy and mechanisms of change of two self-help books for social anxiety in college students in a randomized controlled trial. One book is based on traditional cognitive behavioral therapy and one is based on acceptance and commitment therapy. This study will test the following hypotheses: Hypothesis 1: The CBT and ACT book conditions will both experience decreased social anxiety and distress. Life satisfaction and values progress will increase in both conditions. Hypothesis 2: The CBT condition will result in greater use of reappraisal, the ACT condition will not. Hypothesis 3: The ACT condition will result in greater use of defusion and decreased psychological inflexibility; the CBT condition will not. Hypothesis 4: Changes in experiential avoidance and defusion will predict changes in social anxiety and values progress in the ACT condition. Hypothesis 5: Changes in reappraisal will predict changes in social anxiety in the CBT condition. Change in values progress will be predicted by change in social anxiety in the CBT condition. Hypothesis 6: The association between social anxiety/negative affect and values progress will decrease or disappear in the ACT condition (i.e., decoupling), and remain the same in the CBT condition.
The present work aims to develop a randomized clinical trial with a sample of 165 patients diagnosed with an emotional disorder. All participants are tested by several self-reports related to common mental disorders in a repeated measures design, pre and post treatment as well as a six month follow up. We think this study will demonstrate that brief psychological treatments should be prioritized over pharmacological treatment for such pathologies in the Primary or Secondary Care context to improve the patient´s quality of life while simultaneously reducing costs.
Background: Attention bias modification training (ABMT) and cognitive behavioral therapy (CBT) likely target different aspects of aberrant threat responses in anxiety disorders and may be combined to maximize therapeutic benefit. However, studies investigating the effect of ABMT in the context of CBT have yielded mixed results. Objective: The primary goal of this project is to utilize an enhanced ABMT to target attentional bias towards threat, in addition to classic CBT for anxiety disorders in youth, to determine the efficacy of ABMT in the context of CBT. Study Population: 121 youth (8-17 years old) with a primary anxiety disorder diagnosis Methods: In this sub-study, - Participants will receive open CBT treatment. - Open CBT treatment will be augmented with computer-based attention retraining, delivered in a randomized-controlled design, with random assignment to either active or placebo attention-training regimens. - This enhanced ABMT integrates a modified dot-probe task used in previous studies, where a target is always presented at the previous location of the neutral and not the simultaneously presented threatening stimulus, with a visual search, where the targets are always presented distally of threatening distractors. - These two training elements (modified dot-probe and visual search) will be embedded in an engaging game to foster motivation and adherence. Outcome: Symptom improvement will be compared between the two study arms.
The Specifying and Treating the Anxiety Phenotype in Autism Spectrum Disorder (STAAR) study aims to better characterize the sub-group of children and preadolescents with ASD that exhibit clinically significant anxiety by conducting a 16-week randomized comparative treatment trial of the Behavioral Intervention for Anxiety in Children with Autism (BIACA), the medication sertraline, and placebo in youth with ASD ages 8-14 years old. The study involves 2-3 half day telehealth visits for behavioral and medical assessments, 1-2 lab visits for safety testing, and 1-2 optional fMRI visits. The study provides 16-weeks of anxiety treatment involving weekly BIACA therapy either in-person or through telehealth, or medical check-up visits either at the UC Davis MIND Institute or via telehealth. After study completion a 3 month follow up call is conducted and participants in the placebo group are given the option to participate in an additional study phase with the study treatment of their choice. Study participation can be done remotely through the use of telehealth and local labs, visits to the UC Davis MIND Institute are not required for most participants.
Multicenter study comparing paroxetine (n=30) versus thermal cure (n=30) in patients with a diagnosis of Generalised Anxiety Disorders
Emerging neuroimaging studies have shown that the cerebellum contributes to different aspects of timing, prediction, learning, and extinction of conditioned responses to aversive stimuli, factors that may be relevant to the success of exposure based behavioral therapy. Our goals are to determine the cerebellar contributions to fear extinction by attempting to modulate key pathways in this process by theta burst stimulation. The long term goal is to lay the foundation for future studies in which neuromodulation is used to augment exposure therapy.
This study is done to evaluate the effects of Mindfulness Based Cognitive Therapy (MBCT) for primary care patients that have mild to moderate symptoms of depression and anxiety. Half of the study participants will receive treatment as usual (TAU), and the other half will receive TAU plus MBCT. The investigators will be comparing changes in symptoms of depression and anxiety between the groups, and hypothesize that the TAU plus MBCT group will have significantly lower symptoms of depression and anxiety compared to TAU group post-intervention
The research will utilise an open feasibility parallel groups trial to examine the impact of novel internet-delivered cognitive behavioural therapy (CBT) interventions for stress, anxiety, and depression compared to treatment as usual (face to face counselling and psychotherapy) in an employment context. Participants will consist of employees accessing services provided by employee assistance programmes (EAP) provided at the European headquarters of a large technology organisation.
