Filter by:This study will examine the efficacy of a computerized cognitive behavioral therapy (CCBT) program for children with anxiety and autism spectrum disorders.
Due to the considerable prevalence of anxiety in youth with autism spectrum disorders, this study seeks to establish the efficacy of a modified cognitive behavioral therapy protocol in 50 adolescents versus other available treatment options.
The primary objective of this study is to determine if N-Acetylcysteine (NAC) has efficacy as an augmentation agent in the treatment of treatment-resistant obsessive-compulsive disorder (OCD). The investigators predict that NAC will reduce OCD symptoms after sixteen weeks of add-on treatment as measured by the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS).
This study aimed at verifying whether sessions of repetitive transcranial magnetic stimulation over a certain brain area (the supplementary motor area) could be useful in the relief of Obsessive-Compulsive Disorder symptoms.
In this trial, we test if adding an Internet-based booster program to regular Internet-based cognitive behavior therapy (ICBT) is effective for patients with obsessive-compulsive disorder (OCD).
The goal of this project is to improve access to effective treatments for obsessive compulsive disorder (OCD) through the use of web-based cognitive behavioral therapy (CBT) treatment. There intervention involves both a computer program (BT Steps) and human interaction via telephone. The investigators will test the efficacy and feasibility of computer therapy alone (n=35), computer plus a non-therapist coach (n=35), and computer plus a CBT therapist coach (n=35
Cognitive behavior therapy is the most effective treatment of obsessive-compulsive disorder. However, the majority of treated patients remain symptomatic. The metacognitive therapy by Wells (1997) could achieve substantial gains in first pilot studies. The purpose of this study is to investigate this approach with a randomized controlled trial by comparing metacognitive therapy with exposure and response prevention for obsessive-compulsive disorder.
The purpose of this research study is to further investigate how well cognitive-behavioral psychotherapy works to reduce obsessive-compulsive symptoms in young children with obsessive-compulsive disorder (OCD). Cognitive-behavioral therapy has been shown to work well in youth with OCD and other anxiety disorders; however, there are only a few studies to date in preschool and young children with OCD. All children will have the option to receive 12 twice-weekly cognitive-behavioral psychotherapy sessions that are up to 60-minutes each. Randomly determined, half of all children will receive these sessions immediately following the pre-assessment and the remaining half will receive them after six weeks. The investigators expect that youth receiving the study-based therapy will show more improvement in OCD symptoms in six weeks in contrast to youth waiting to receive the therapy.
The purpose of this project is to study live recordings from neuronal population of the human nucleus accumbens during the implantation of deep brain stimulation (DBS) electrodes for the treatment-resistant obsessive compulsive disorder (OCD). The central aim of this project is to determine if intra-operative electrophysiological data can confirm that the electrode is located in the nucleus accumbens. This confirmation could allow the placement of the DBS electrodes with a higher degree of precision. An additional aim of this project will be to study the activity of the neuronal population of the nucleus accumbens while a subject is presented with a task involving an unexpected reward. The investigators central hypothesis is that unexpected reward will be associated with increase firing and synchrony in the neuronal population. This will translate into recordable increase activity in the investigators region of interest and therefore confirm the proper placement of the electrode. This study enrolled 2 subjects, with 1 subject completing the protocol showing the feasibility of the experiment. There were electrophysiological variations with the task presented but no conclusion could be drawn given the small sample size.
This experiment will examine if the use of computerized tasks that train individuals to control their attention more effectively will predict individual differences in obsessive-compulsive symptoms, rumination and BDNF change. After giving consent, filling out self-report forms, and giving blood for the BDNF test, 80 participants will be randomized to Cognitive Control Training (CCT) or Peripheral Vision Task (PVT) (described below) which will be administered three times over a two week period. At the third visit, participants will also complete an anagram task and repeat the blood draw for BDNF testing. The investigators hypothesize that computerized tasks that train individuals to control their attention more effectively will reduce Obsessive Compulsive (OC) symptoms. Additionally, individuals training in CCT will show increased ability to disengage from unattainable goals as assessed by responses to an unsolvable anagram task. Finally, individuals training in CCT will show a greater increase in BDNF levels as compared to individuals training in PVT.
