Filter by:Social anxiety disorder (SAD) is a prevalent mental health concern that impacts approximately 12% of the population. One mechanism thought to maintain SAD is avoidance of faces (i.e. avoidance of negative evaluative threat). However, research on attentional processes in SAD has been confined to paradigms presented on computer monitors. To investigate attentional processes in a more naturalistic way the investigators developed an immersive, 360º-video virtual reality environment using real actors, as part of a pilot study. Participants with a range of social anxiety symptoms (from none to severe) completed a 5-minute speech in this virtual reality environment while their eye movements were recorded. Results from the study showed that greater symptoms of social anxiety were associated with avoidance of looking at faces (i.e. fewer fixations on faces). While existing treatments for SAD are moderately effective, a large number of individuals do not experience meaningful reductions in their symptoms. The overarching goal of this project is inform future treatment research for SAD. The investigators will test a brief attention guidance intervention for SAD that specifically targets avoidance of faces as a potential mechanism maintaining the disorder. The proposed research will use the eye tracking hardware and naturalistic virtual reality environment from the pilot study. The investigators will also collect eye tracking data prior to the intervention in order to investigate potential heterogeneity in the attentional processes of SAD. The investigators will test the hypotheses that (a) the attention guidance intervention, compared to the control intervention, will result in a greater reduction in symptoms of social anxiety, and (b) this effect will be mediated by the number of fixations on faces during a brief public speaking challenge following the intervention. These results will provide causal evidence related to a hypothesized mechanism maintaining SAD.
The investigators propose to develop and adapt Unwinding Anxiety phone app specifically for individuals with generalized anxiety disorder.
The overall objective of the activities described in this protocol is to examine the efficacy of the Internet-based intervention in the reduction of dental anxiety in patients seeking dental treatment. This study has 2 primary objectives and 2 secondary objectives: Primary Objective 1-Therapy Aides: To compare the efficacy of the intervention as administered by personnel with training and experience in cognitive behavioral therapy (CBT) to the efficacy of the intervention as administered by dental staff who have undergone a brief but specific training in the administration of the intervention. Primary Objective 2-Intervention Efficacy: To compare the efficacy of the intervention, administered by either type of therapy aide (CBT personnel or dental staff), to an active control condition. Secondary Objective 1-Tests of Moderators: To examine whether baseline levels of distress tolerance and pain sensitivity moderate the efficacy of the dental anxiety intervention, regardless of therapy aide, in comparison to an active control condition. Secondary Objective 2-Other Intervention Effects: To explore effects of the intervention beyond primary efficacy, including attendance at recall visits in the 12 months after the intervention; pain intensity; avoidance due to fear of dental procedures; and client satisfaction.
Ideal interventions for the older aged population would be those that are easily accessible and associated with minimal burden on family members, the healthcare system and the individuals themselves. Mindfulness-Based Stress Reduction (MBSR) therapy and Transcranial Direct Current Stimulation (tDCS) are two interventions that may be effective in targeting cognitive deficits in individuals with anxiety, depression, and/or cognitive complaints. MBSR has been shown to decrease symptoms of depression and improve cognition and tDCS has been shown to improve cognition in the older aged population. The effectiveness of these two interventions combined to elicit changes in cognition has yet to be demonstrated. Therefore, the overall aim of the current research is to evaluate the efficacy of a combination of MBSR and tDCS to improve cognitive function in individuals with cognitive complaints and symptoms of anxiety and/or depression. This will be a randomized pilot study. Sixteen individuals (separated into 2 groups of 8) will be randomized to receive a combination MBSR + active tDCS or MBSR + sham tDCS over 8 weeks. Participants will visit the Centre for Addiction and Mental Health (CAMH) once per week for in-class group sessions and will complete the intervention daily at home for the duration of the study. Participants will be aged 60 and older with cognitive complaints, with symptoms of anxiety and/or depression. Participants will be trained to self-administer tDCS and given guidelines for the completion of daily MBSR activities at home. It is hypothesized that the combination of active tDCS + MBSR will enhance cognition compared to the combination of sham tDCS + MBSR.
Background: Outpatient pediatric orthopedic procedures such as percutaneous pins removal and sutures are considered painful and generate significant stress and anxiety in children. However, given their short duration and the need for a quick turnover in outpatient clinics, there are very few interventions aimed at relieving pain, stress and anxiety related to these procedures. Neither simple analgesia nor topical anesthetics proved effective for procedural pain reduction with this population. Moreover, narcotics and procedural sedation do not appear to be feasible alternatives as they require surveillance, prolonging visit to the outpatient clinic and generating several undesired side effects. Therefore, it would be imperative to explore non-pharmacological pain management methods as they require minimal preparation and do not usually generate any side effects. Aim: To examine the effect of virtual reality (VR) compared to passive distraction, on pain, stress, anxiety and memory of pain in children undergoing a percutaneous pin removal procedure or sutures in an outpatient orthopedic clinic. Hypothesis: VR distraction provides better pain relief during percutaneous pin removal procedures or sutures than passive distraction, in children from 7 to 21 years old. Methods: The study will be a prospective randomized controlled trial with parallel groups. Children from 7 to 21 years old, visiting the clinic for follow up and percutaneous pin removal procedure or sutures, accompanied by a parent or legal guardian will be recruited. The experimental group will receive a VR distraction through a head-mounted Oculus Quest® and the control group will receive passive distraction through watching a video on an iPad®. The primary outcome will be the mean pain score after the procedure (self-report of pain level during the procedure) measured by the Numerical Rating Scale (NRS). Anxiety will be measured by the Child Fear Scale (CFS) and stress will be measured using level of salivary Alpha-Amylase before and 10-min after the procedure. Memories of pain and anxiety will be measured one week after the procedure using the same scales (NRS and CFS). The investigators aim to recruit 188 children. Discussion: The investigators believe that results of this study will allow to improve pain, stress and anxiety management practices in this orthopedic clinic by showing that non-pharmacological interventions can be done, at very low cost, to improve the experience of the child undergoing these painful procedures through an innovative and more humanistic approach.
The purpose of the study is to evaluate the effectiveness of the virtual 360° counselling environment in the anxiety and process time of the patients coming to CCTA (coronary computed tomography angiography). The virtual, 360° environment 'Virtual 360°-tour in coronary computed tomography' uses 360°- technology based on spherical panorama images and resembles the spaces of the hospital according to the patient's pathway in CT-examination and provides information to the patient at various stages of the pathway.
Autograft is a technique requiring several weeks of hospitalization in a protected environment and can be a source of anxiety of different natures for patients. In this study, level of anxiety will be reported weekly throughout hospitalizations for autologous transplant, to detect the most stressful period.
This is a prospective, randomized clinical trial to investigate the clinical impact of a preemptive pharmacogenomics strategy to guide antidepressant therapy in cancer patients. Those enrolled onto the clinical trial will be randomized to either DNA-guided choice of therapy or clinical management alone. Scores on self-reported measures of depressive and anxiety symptoms along with quality of life will be compared between cohorts.
This study assesses whether a 4-week computerized intervention can be used to decrease fear of intimacy, and loneliness and improve perceived social support in people with Social Anxiety Disorder.
The research objective of this proposed clinical trial is to determine the efficacy of a medical clowning intervention for pediatric patients undergoing venipuncture. Efficacy is defined in terms of decreasing anxiety, pain, and crying duration, and increasing the pace and ease of the procedure. The study population includes pediatric patients between the ages of 3 - 11 years who must undergo venipuncture at the LAC + USC Outpatient Clinic. The subjects will be randomized into two groups. The control subjects will receive no intervention during blood draw, while the intervention subjects will receive the medical clown intervention during blood draw. The clowns will interact with one patient at a time, engaging in play with the patient and caretakers during all parts of the procedure. Duration of crying and the duration of the entire procedure, the patient's level of pain and anxiety, the caretaker's level of anxiety, need for restraining devices (papoose) and the efficiency of the procedure will be measured. In order to perform the survey and self-assessment procedures, we will implement the use of measurement scales including a novel "emoji" child distress assessment scale, and a published adult anxiety scale (State-Trait Anxiety Inventory Form Y-1). The data will be analyzed using descriptive statistics.
