Background: Cognitive bias theories propose that reducing threat hypervigilance in mental disorders can augment cognitive behavioral therapy (CBT) outcomes. However, no studies have tested whether adding attention bias modification (ABM) can effectively enhance CBT's effects on anxiety sensitivity (AS), electromyography (EMG), and skin conductance (SC) for panic disorder (PD). This pilot randomized controlled trial (RCT) thus aimed to evaluate the efficacy of CBT + ABM (vs.

Trauma-informed beliefs often decrease during posttraumatic stress disorder (PTSD) treatment. This may also extend to anxiety sensitivity (AS), defined as a fear of anxiety-related sensations and beliefs that anxiety is dangerous and/or intolerable. However, little is known about how AS changes during exposure-based and psychopharmacological PTSD treatments.

Importance: Anxiety disorders are common, highly distressing, and impairing conditions. Effective treatments exist, but many patients do not access or respond to them. Mindfulness-based interventions, such as mindfulness-based stress reduction (MBSR) are popular and can decrease anxiety, but it is unknown how they compare to standard first-line treatments.

Cognitive-behavioral therapy (CBT) is a first-line, empirically supported intervention for anxiety disorders. CBT refers to a family of techniques that are designed to target maladaptive thoughts and behaviors that maintain anxiety over time. Several individual CBT protocols have been developed for individual presentations of anxiety.

The current study is an analysis of predictors of posttraumatic stress disorder (PTSD) treatment response in a clinical trial comparing (1) prolonged exposure plus placebo (PE + PLB), (2) PE + sertraline (PE + SERT), and (3) sertraline + enhanced medication management (SERT + EMM) with predictors including time since trauma (TST), self-report of pain, alcohol use, baseline symptoms, and demographics. Participants (N = 196) were veterans with combat-related PTSD () of at least 3 months' duration recruited between 2012 and 2016 from 4 sites in the 24-week PROlonGed ExpoSure and Sertraline (PROGrESS) clinical trial (assessments at weeks 0 [intake], 6, 12, 24, 36, and 52). Across treatment conditions, (1) longer TST was predictive of greater week 24 PTSD symptom improvement (β = 1.

Background: Poor quality of life, sleep problems, anhedonia, and negative metacognitions are common in anxiety and depression. To examine the nature of the relationship between these features and the role of metacognitions, anhedonia, and quality of life in anxiety and depression, we conducted a complex network analysis with items of self-report measures assessing quality of life, sleep, negative thinking styles, anxiety, and depression.

Methods: Participants were 226 treatment seeking individuals with a primary DSM-5 diagnosis of generalized anxiety disorder.

Background: Treatments for anxiety disorders are among the most effective in psychiatry. Yet, there is considerable room for improvement.

Aim: In this paper, we discuss the value of ecological momentary assessment as a research method and clinical tool.

Anxiety and depressive symptoms are associated with lower levels of mindfulness, yet few studies to date have examined facets of mindfulness in adults with Generalized Anxiety Disorder (GAD). In this study, we examined differences in mindfulness between individuals with GAD with and without concurrent Major Depressive Disorder (MDD) and/or Dysthymic Disorder (DD). We also examined the associations of anxiety and depressive symptoms with facets (subscales) of mindfulness.

Article Synopsis
  • Exposure therapy for social anxiety disorder (SAD) combined with naps was tested to see if sleep enhances symptom relief and biomarker responses.
  • The study involved 32 adults undergoing 5 weeks of group therapy, with participants either taking a nap or staying awake after exposure sessions.
  • While primary outcomes showed no difference in symptom change with naps, some secondary biomarkers suggested that naps might improve stress responses, indicating a need for further research with larger sample sizes and better sleep interventions.

Individuals with social anxiety disorder (SAD) or generalized anxiety disorder (GAD) are at risk for not utilizing mental health treatment. The purpose of this research was to examine barriers to treatment in a sample of adults with clinically significant SAD or GAD. Participants were 226 nontreatment-seeking adults with SAD or GAD who underwent semistructured diagnostic interview and received a clinician assessment of symptom severity as part of a clinical research study.

Knowledge about what psychological characteristics underlie complicated grief (CG) is limited. The current study examined the five-factor personality traits in 81 bereaved adults with (n = 51) and without (n = 30) CG. A trained doctoral-level clinician evaluated participants using a structured, diagnostic psychiatric interview, and they completed self-report measures of grief and personality.

Bereavement is a potent and highly prevalent stressor among service members and veterans. However, the psychological consequences of bereavement, including complicated grief (CG), have been minimally examined. Loss was assessed in 204 post-9/11, when service members and veterans with combat-related posttraumatic stress disorder (PTSD) took part in a multicenter treatment study.

Introduction: There is mixed evidence in the literature on the role of inflammation in major depressive disorder. Contradictory findings are attributed to lack of rigorous characterization of study subjects, to the presence of concomitant medical illnesses, to the small sample sizes, and to the limited number of cytokines tested.

Methods: Subjects aged 18-70 years, diagnosed with major depressive disorder and presenting with chronic course of illness, as well as matched controls ( n = 236), were evaluated by trained raters and provided blood for cytokine measurements.

Anxiety Sensitivity (AS) has been associated with sleep difficulties in certain anxiety disorder populations, but no studies have examined cross-diagnostically the role of anxiety sensitivity in sleep dysfunction. Three hundred one participants with generalized anxiety disorder (GAD), social anxiety disorder (SAD), and panic disorder (PD) completed an ancillary questionnaire-based study. Linear regression was used to examine AS and sleep dysfunction, and mediation analyses were used to examine whether AS was a mediator of the effect of primary diagnosis on sleep.
