Efficacy of a single session mindfulness based intervention: A randomized clinical trial.

Loneliness, perceived stress, depression, and anxiety have increased during the COVID-19 pandemic. Many of existing mindfulness and compassion-based intervention are effective, but are time-intensive, decreasing overall accessibility and scalability. Single-session interventions (SSIs) serve as a promising alternative.

Testing a brief attention training protocol to prevent emotional distress from a fear induction procedure.

Background And Objectives: Attentional hypervigilance to threat in posttraumatic stress disorder (PTSD) is an important topic to investigate. Efforts to leverage attention training to prevent PTSD have been promising but underlying mechanisms have not been fully elucidated. The current study tested whether Attention Bias Modification (ABM) prior to an emotion induction of fear could reduce self-reported fear and arousal compared to two control conditions.

Attentional heterogeneity in social anxiety disorder: Evidence from Hidden Markov Models.

There is some evidence for heterogeneity in attentional processes among individuals with social anxiety. However, there is limited work considering how attentional processes may differ as a mechanism in a naturalistic task-based context (e.g.

Multimodal Remote Research on Social Anxiety Using a New Teleconferencing Paradigm.

Background: Social anxiety is a prevalent mental health concern. Models of social anxiety incorporate multifaceted components from cognitive appraisals to attention as factors maintaining the disorder. Multimodal research investigating multiple facets of social anxiety simultaneously offers an important avenue to advance our understanding of the disorder.

Low reliability when determining criterion a for posttraumatic stress disorder from self-report descriptions of traumatic events: The need for transparent methods.

Objective: Exposure to a traumatic event is a primary criterion (Criterion A) for meeting Posttraumatic Stress Disorder (PTSD). Using self-report to establish diagnostic criteria in research has become more common, especially with internet-based research. However, some individuals may construe events as traumatic when they do not meet Criterion A.

Use of Cannabidiol (CBD) oil in the treatment of PTSD: Study design and rationale for a placebo-controlled randomized clinical trial.

Background: The burden of illness for PTSD is staggering and confers significant interference in work, social functioning, as well as increased risk for other physical and mental health problems. Recently, there's been considerable attention paid to the potential therapeutic use of cannabidiol (CBD) products in the treatment of a variety of physical and mental health problems. The endocannabinoid system (ECS) is a logical therapeutic target for combating PTSD and other fear-based disorders given that cannabinoid receptors and other molecular mediators crucial for ECS signaling are richly expressed in a variety of brain regions that govern the regulation of learned fear and defensive behavior.

Attention guidance augmentation of virtual reality exposure therapy for social anxiety disorder: a pilot randomized controlled trial.

Biased attention to social threats has been implicated in social anxiety disorder. Modifying visual attention during exposure therapy offers a direct test of this mechanism. We developed and tested a brief virtual reality exposure therapy (VRET) protocol using 360°-video and eye tracking.

Selective visual attention during public speaking in an immersive context.

It has recently become feasible to study selective visual attention to social cues in increasingly ecologically valid ways. In this secondary analysis, we examined gaze behavior in response to the actions of others in a social context. Participants (N = 84) were asked to give a 5-minute speech to a five-member audience that had been filmed in 360° video, displayed in a virtual reality headset containing a built-in eye tracker.

The influence of PTSD symptoms on selective visual attention while reading.

A large body of research has provided evidence that Posttraumatic Stress Disorder (PTSD) symptoms are associated with broad changes in attentional processes which are in turn implicated in core facets of emotion regulation. However, prior research has primarily focused on specific task-based evaluations of attention. In the current study, we evaluated eye movement behaviour among adults that endorsed a traumatic event meeting Criterion A and were experiencing a range of PTSD symptoms ( = 55) while they read short trauma-related or neutral passages.

Exploratory and Confirmatory Bayesian Networks Identify the Central Role of Non-judging in Symptoms of Depression.

Objectives: Depression is a highly heterogeneous disorder, and meta-analyses of mindfulness-based interventions show moderate efficacy for reducing depressive symptoms. However, the mechanisms governing their efficacy remain unclear, highlighting the need for hypothesis-generating analyses to guide future research.

Methods: We used Bayesian network analysis in three cross-sectional samples  = 1135) of undergraduates and participants from the community to identify links between individual symptoms of depression and specific facets of mindfulness.

Distinct trajectories of depression symptoms in early and middle adolescence: Preliminary evidence from longitudinal network analysis.

Adolescent depression is a clinically relevant concern that has major implications for mental and physical health. The trajectory of depressive symptoms among adolescents suggests that there is likely variability throughout this developmental period. The aim of the study was to assess the longitudinal relationship between individual symptoms of depression among early and middle adolescents to provide guidance for future research investigating targeted intervention efforts.

Rising to the Occasion of This COVID-19-Impacted Nation: Development, Implementation, and Feasibility of the Brief Assessment-Informed Skills Intervention for COVID-19 (BASIC).

The COVID-19 pandemic has had a profound impact on the global economy, physical health, and mental health. This pandemic, like previous viral outbreaks, has resulted in spikes in anxiety, depression, and stress. Even though millions of individuals face the physical health consequences of infection by COVID-19, even more individuals are confronted with the mental health consequences of this pandemic.

Pupillary Response to Affective Voices: Physiological Responsivity and Posttraumatic Stress Disorder.

Posttraumatic stress disorder (PTSD) is related to dysfunctional emotional processing, thus motivating the search for physiological indices that can elucidate this process. Toward this aim, we compared pupillary response patterns in response to angry and fearful auditory stimuli among 99 adults, some with PTSD (n = 14), some trauma-exposed without PTSD (TE; n = 53), and some with no history of trauma exposure (CON; n = 32). We hypothesized that individuals with PTSD would show more pupillary response to angry and fearful auditory stimuli compared to those in the TE and CON groups.

Avoidance of social threat: Evidence from eye movements during a public speaking challenge using 360°- video.

Social anxiety (SA) is thought to be maintained in part by avoidance of social threat, which exacerbates fear of negative evaluation. Yet, relatively little research has been conducted to evaluate the connection between social anxiety and attentional processes in realistic contexts. The current pilot study examined patterns of attention (eye movements) in a commonly feared social context - public speaking.

Pretreatment Posttraumatic Stress Disorder Symptom Network Metrics Predict the Strength of the Association Between Node Change and Network Change During Treatment.

Network analysis has been increasingly applied in an effort to understand complex interactions among symptoms in posttraumatic stress disorder (PTSD). Although methods that initially focused on identifying central symptoms in cross-sectional networks have been extended to longitudinal data that can reveal the relative roles of acute symptoms in the emergence of the PTSD syndrome, the association between network metrics and symptom change during treatment have yet to be explored in PTSD. To address this gap, we estimated pretreatment PTSD symptom networks in a sample of patients from a multisite clinical trial for women with full or subthreshold PTSD and substance use.

Emotional reactivity to grief-related expressive writing.

The efficacy of expressive writing for bereavement remains unclear, although some evidence suggests that writing about positive memories of one's loved one may be particularly beneficial. The current pilot study compared the effects of a brief positive expressive writing intervention for enhancing positive affect among bereaved adults ( = 403). Participants were randomly assigned to write about a positive memory of the deceased person or recent neutral activity.

Gone in sixty (milli)seconds: Disentangling the effects of location context on attention bias.

Attention bias is associated with a broad range of emotional disorders. Because of its transportability, attention bias modification (ABM) training can be administered outside of the laboratory; however, some evidence suggests that ABM training may be less effective when conducted in the individual's natural environment. The aim of this study was to examine factors that might account for the attenuated effects of attentional bias (AB) when assessed remotely.

Inhibitory Control under Threat: The Role of Spontaneous Eye Blinks in Post-Traumatic Stress Disorder.

This study is the first to explore spontaneous eye blink rate (sEBR) in individuals with post-traumatic stress disorder (PTSD). We investigated the connection between the magnitude of flanker interference in PTSD participants and sEBR during performance on a modified version of the Eriksen flanker task. As a peripheral measure of cognitive control and dopaminergic function, sEBR may illuminate the relationship between PTSD and executive function.

Greater hippocampal volume is associated with PTSD treatment response.

Previous research associates smaller hippocampal volume with posttraumatic stress disorder (PTSD). It is unclear, however, whether treatment affects hippocampal volume or vice versa. Seventy-six subjects, 40 PTSD patients and 36 matched trauma-exposed healthy resilient controls, underwent clinical assessments and magnetic resonance imaging (MRI) at baseline, and 10 weeks later, during which PTSD patients completed ten weeks of Prolonged Exposure (PE) treatment.

PTSD REMISSION AFTER PROLONGED EXPOSURE TREATMENT IS ASSOCIATED WITH ANTERIOR CINGULATE CORTEX THINNING AND VOLUME REDUCTION.

Background: Brain structures underlying posttraumatic stress disorder (PTSD) have been a focus of imaging studies, but associations between treatment outcome and alterations in brain structures remain largely unexamined. We longitudinally examined the relation of structural changes in the rostral anterior cingulate cortex (rACC), a previously identified key region in the PTSD fear network, to outcome of prolonged exposure (PE) treatment.

Method: The sample included 78 adults (53 women): 41 patients with PTSD and 37 trauma-exposed healthy volunteers (TE-HCs).

Linguistic characteristics in a non-trauma-related narrative task are associated with PTSD diagnosis and symptom severity.

Linguistic characteristics of trauma narratives have been linked to the development and severity of posttraumatic stress disorder (PTSD). However, it remains unclear if linguistic markers of PTSD exist beyond the scope of trauma narratives. This study used ambiguous visual prompts to elicit spontaneous narratives from trauma-exposed individuals with (n = 23) and without PTSD (n = 30).
