A preliminary examination of the acceptability, feasibility, and effectiveness of a telehealth cognitive-behavioral therapy group for social anxiety disorder

In light of the growing interest in, and need for, the telehealth delivery of health care, additional research is needed on the acceptability and effectiveness of these types of interventions. This study examined the acceptability, feasibility, and preliminary effectiveness of an adapted telehealth-delivered group cognitive-behavioral therapy (CBT) intervention for adults with social anxiety disorder (SAD). This report describes the adaptation and subsequent implementation of an 8-week telehealth-delivered group treatment designed to reduce symptoms of SAD. Specific adaptations for delivering treatment during the COVID-19 pandemic and the subsequent enactment of social distancing measures are discussed. Posttreatment data indicated that the intervention was feasible to implement in an outpatient mental health clinic, acceptable to participants, and associated with reduction in symptoms of social anxiety, general anxiety, depression, and stress.Accepted manuscrip

Efficacy and mechanisms underlying a gamified attention bias modification training in anxious youth: protocol for a randomized controlled trial

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. Here, we propose an enhanced ABMT to target the attentional bias towards threat, in addition to classic CBT for anxiety disorders in youth. This enhanced ABMT integrates the 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) are embedded in an engaging game to foster motivation and adherence. Our goal is to determine the efficacy of the enhanced ABMT in the context of CBT. Further, we aim to replicate two previous findings: (a) aberrant amygdala connectivity being the neurobiological correlate of the attentional bias towards threat at baseline; and (b) amygdala connectivity being a mediator of the ABMT effect. We will also explore moderators of treatment response (age, sex, depressive symptoms and irritability) on a behavioral and neuronal level. Methods One hundred and twenty youth (8–17 years old) with a primary anxiety disorder diagnosis all receive CBT and are randomized to nine weeks of either active or control ABMT and symptom improvement will be compared between the two study arms. We will also recruit 60 healthy comparison youth, who along with eligible anxious youth, will be assessed with the dot-probe task during fMRI (anxious youth: before and after training; healthy volunteers: second measurement twelve weeks after initial assessment). Discussion The present study will contribute to the literature by (1) potentially replicating that aberrant amygdala connectivity mediates the attentional bias towards threat in anxious youth; (2) determining the efficacy of enhanced ABMT; and (3) advancing our understanding of the mechanisms underlying ABMT. Trial registration Clinicaltrials.gov: NCT03283930 Trial registration date: September 14th 2017. The trial registration took place retrospectively. Data acquisition started February 1st 2017

ABMT Brain Imaging

This project examines relationships among anxiety, brain function, and treatment in youth. The project includes a randomized controlled trial, where medication-free youth receive treatment for an anxiety disorder. These youths all receive cognitive behavioral therapy (CBT), and half are randomized to an active form of Attention Bias Modification Training (ABMT), whereas the other half are randomized to an inactive form of ABMT. The project also includes collection of data in health youth matched at a group level on age, gender, and intelligence with the anxiety disorder group. All subjects receive two assessment of brain function with the same fMRI version of the dot-probe task. The study tests three sets of hypotheses, all designed to replicate or extend findings in White et al. Am J Psychiatry 2017. The first set of hypotheses examine associations between brain function and anxiety, using the dot-probe task. These involve two sets of analyses, one that examines relationships between brain function and anxiety diagnosis using a categorical approach as well as a second that examines relationships between brain function and anxiety symptoms using a continuous approach. The second hypothesis compares the response to the active and inactive forms of ABMT in the treatment-seeking patients. The third set of hypotheses examine relationships between brain function on the dot-probe task and treatment outcome among the patients

Development of Neural Mechanisms Underlying Threat Processing:Associations With Childhood Social Reticence and Adolescent Anxiety

Background: Social reticence in early childhood is characterized by shy and anxiously avoidant behavior, and it confers risk for pediatric anxiety disorders later in development. Aberrant threat processing may play a critical role in this association between early reticent behavior and later psychopathology. The goal of this longitudinal study is to characterize developmental trajectories of neural mechanisms underlying threat processing and relate these trajectories to associations between early-childhood social reticence and adolescent anxiety. Methods: In this 16-year longitudinal study, social reticence was assessed from 2 to 7 years of age; anxiety symptoms and neural mechanisms during the dot-probe task were assessed at 10, 13, and 16 years of age. The sample included 144 participants: 71 children provided data at age 10 (43 girls, meanage = 10.62), 85 at age 13 (46 girls, meanage = 13.25), and 74 at age 16 (36 girls, meanage = 16.27). Results: A significant interaction manifested among social reticence, anxiety symptoms, and time, on functional connectivity between the left amygdala and the left dorsolateral prefrontal cortex, voxelwise p &lt; .001, clusterwise familywise error p &lt; .05. Children with high social reticence showed a negative association between amygdala–dorsolateral prefrontal cortex connectivity and anxiety symptoms with age, compared to children with low social reticence, suggesting distinct neurodevelopmental pathways to anxiety. Conclusions: These findings were present across all conditions, suggesting task-general effects in potential threat processing. Additionally, the timing of these neurodevelopmental pathways differed for children with high versus low social reticence, which could affect the timing of effective preventive interventions.</p
