Neural Markers of Treatment Mechanisms and Prediction of Treatment Outcomes in Social Anxiety
Social Anxiety DisorderThe purpose of this clinical trial is to answer the question: can the investigators predict which adults with social anxiety disorder (SAD) will successfully respond to treatment? To answer this question, the investigators plan to recruit 190 adult participants who experience extreme forms of social anxiety to undergo brain imaging before and after 12 weeks of group cognitive behavioral therapy (CBT). Adults in the SAD group who do not respond enough to group CBT may be offered the opportunity to complete an additional 12 weeks of individual CBT while receiving SSRI medication (sertraline, see below) for SAD. Data collected from participants who experience anxiety will be compared to a group of 50 participants with little or no social anxiety, who will serve as a comparison group.
Targeting Attention Orienting to Social Threat to Reduce Social Anxiety in Youth
Social Anxiety Disorder of ChildhoodThis two-site study is a test of Attention Bias Modification Treatment (ABMT) among 260 youths ages 10 to 14 years with social anxiety disorder. One-half of participants will receive 8 sessions of computer administered ABMT and the other half of participants will receive 8 sessions of computer administered Neutral Control Task (NCT). The investigators hypothesize that a biomarker of attention to social threat measured using electroencephalography (EEG) and ratings of social anxiety severity will be lower in participants who receive ABMT compared to participants who receive NCT.
Sexual Confidence: CBT for Social Anxiety Disorder With HIV Risk Reduction Counselling for HIV-negative...
Social AnxietySexual Risk1 moreGiven the continued high human immunodeficiency virus (HIV) prevalence rates among gay, bisexual, and other men who have sex with men (MSM) in North American cities, there is a critical need for HIV prevention interventions for MSM in Canada. Social anxiety, or anxiety about being evaluated in interpersonal and performance situations, is a reliable risk factor for condomless anal sex (CAS) among MSM. Social anxiety may also increase substance use in sexual situations, which is another risk factor for HIV among MSM. As such, an empirically-based social anxiety treatment may also reduce HIV risk behaviours among MSM. The present study will provide the first efficacy data for a novel and innovative HIV prevention intervention for MSM. This intervention will build upon empirically supported interventions to reduce HIV risk among MSM and therapies to reduce social anxiety. The investigators propose to test the efficacy of a novel integrated HIV prevention intervention that combines the most empirically supported treatment for social anxiety disorder, cognitive-behavioural therapy, with HIV risk reduction counselling in order to simultaneously treat social anxiety disorder, substance use disorders, and HIV sexual risk behaviour. This study will be a randomized controlled trial comparing the study intervention relative to applied relaxation, a behavioural intervention that is efficacious in treating social anxiety disorder but that does not address substance use problems or HIV sexual risk behaviours. For this trial, 176 participants will be randomized to either 12 sessions of cognitive-behavioural therapy with HIV risk reduction counselling or 12 sessions of applied relaxation. Participants will be eligible for the trial if they are HIV-negative, report clinically significant symptoms of social anxiety disorder, substance use 2 hours before or during sexual activity, and CAS without the use of pre-exposure prophylaxis (PrEP) with a male partner who was not known to be HIV-negative. PrEP is a biomedical prevention approach in which HIV-negative individuals are provided with daily oral antiretroviral medication for the primary prevention of HIV.126 The present intervention, if found to be efficacious, is innovative in that mental health clinicians will be able to not only extend empirically supported therapies tested primarily with heterosexual populations to MSM, but they will also be able to prevent HIV through empirically supported psychotherapy practice.
Computerized Intervention Targeting the Error-Related Negativity and Balance N1 in Anxious Children...
Anxiety DisordersGeneralized Anxiety Disorder2 moreAnxiety disorders are the most common form of psychopathology, and frequently begin in childhood, resulting in lifelong impairment. Increased brain activity after making mistakes, as reflected by the error-related negativity (ERN), is observed in people with anxiety disorders, even before disorder onset. The ERN is therefore of great interest as a potentially modifiable risk factor for anxiety. However, methodological issues can make the ERN difficult to measure. Increased brain activity in response to a balance disturbance, as reflected by the balance N1, resembles the ERN, but does not share its methodological issues. The investigators' preliminary data demonstrate that the balance N1 and the ERN are associated in amplitude in adults, suggesting they may depend on the same brain processes. The balance N1 has never been investigated in individuals with anxiety disorders, but it increases in amplitude within individuals under anxiety-inducing environmental contexts. Further, balance and anxiety are related in terms of brain anatomy, daily behavior, disorder presentation, and response to treatment. The present investigation will measure the ERN and the balance N1 in children (ages 9-12) with anxiety disorders, and further, how these brain activity measures change in response to a brief, 45-minute, computerized psychosocial intervention that was developed to reduce reactivity to errors, and has been shown to reduce the ERN. The investigators will recruit approximately 80 children with anxiety disorders, half of whom will be randomly assigned to the active intervention condition. The other half will be assigned to an active control condition, consisting of a different 45-minute computerized presentation. Participants assigned to the control condition can access the computerized intervention after participation in the study. The purpose of this investigation is to test the hypothesis that the balance N1 and the ERN will be reduced to a similar extent after the intervention, to demonstrate that these brain responses arise from shared brain processes. Transfer of the effect of the psycho-social intervention to the balance N1 would provide insight into prior work demonstrating that balance training can alleviate anxiety in young children, and well-documented benefits of psychotherapy to balance disorders. Collectively, these data may guide the development of multidisciplinary interventions for the prevention and treatment of anxiety disorders in children.

Changing the Course of Social Anxiety in Adolescence
Social Anxiety DisorderSocial anxiety often reaches its peak during adolescence and may hold a noteworthy impact both at the social and academic levels. Though some adolescents easily learn to adequately cope with it, others become overwhelmed by social fears and end up avoiding social events or facing them with intense suffering. Adolescents with social anxiety disorder (SAD) seldom seek professional help and often become adults with SAD, making it necessary to timely intervene during early stages of the disorder and determine what works better, why, and for whom when trying to change the course of social anxiety in adolescence. Cognitive therapy (CT) has been the treatment of choice for adult SAD, but research within adolescent samples is scarce. More recently, third-wave cognitive approaches, namely compassion-focused therapy (CFT) and acceptance and commitment therapy (ACT), have also proven effective in treating mental disorders, but their efficacy towards adolescents' SAD remains unclear. This research project intended to evaluate and compare the therapeutic efficacy of CT, CFT, and ACT as applied to adolescents with SAD, in comparison with waiting-listed, after intervention and over a 12-weeks and a 24-weeks follow-up, using a randomized parallel trial approach. This methodology will allow to test if intervened subjects diverge from the non-intervened SAD subjects, and if therapeutic change differs across intervention conditions. Therapeutic change process will be investigated, specifically if efficacy is mediated by change in the core constructs of each theoretical framework. Finally, moderators of change such the initial level of symptomology will be examined, as to determine which intervention works best for whom. The same procedures will be repeated for each intervention condition, namely recruitment, intervention, and assessment. This research will provide evidence on which form of therapy may be the optimal choice in to intervene in SAD in general, and when dealing with diverse specific vulnerabilities associated with social fears. It will also add to the field of empirically validated therapies, with a specific focus on adolescence. From a societal perspective, the project will assist in empowering schools to contribute to shape how their students act and develop into socially apt adults.
Optimizing Cognitive-behavioral Therapy for Social Anxiety Disorder Using the Factorial Design
Social Anxiety Disorder (Social Phobia)Social Anxiety Disorder (SAD) is characterized by a marked fear of negative evaluation in social situations. It is the third most common psychiatric disorder and highly disabling (American Psychiatric Association, 2000). Although effective treatments such as cognitive-behavioral therapy (CBT) are available, most individuals suffering from SAD do not seek and eventually find help, and even in the best available treatments, remission rates are below 50%. The overall aim of the project is to better understand and improve the efficacy of Internet-based CBT (ICBT) that has shown to be efficacious in many trials and that provide broad and low-threshold access to empirically supported treatments. Specifically the objectives of the study are: to investigate the active ingredients of ICBT for SAD by testing the main effects and interactions for the four main treatment components (i.e., psychoeducation, cognitive restructuring, attention training, and exposure); to investigate the effects of each treatment component on hypothesized change mechanisms, and to explore whether and which change mechanisms mediate the effect of the treatment components on symptom reduction. to investigate whether the specific mechanisms mediate the effect of the treatment components on primary and secondary outcomes.
