Background: This paper reports on the outcomes of a proof-of-principle study for the Exposure Therapy Consortium, a global network of researchers and clinicians who work to improve the effectiveness and uptake of exposure therapy. The study aimed to test the feasibility of the consortium's big-team science approach and test the hypothesis that adding post-exposure processing focused on enhancing threat reappraisal would enhance the efficacy of a one-session large-group interoceptive exposure therapy protocol for reducing anxiety sensitivity.

Methods: The study involved a multi-site cluster-randomized controlled trial comparing exposure with post-processing (ENHANCED), exposure without post-processing (STANDARD), and a stress management intervention (CONTROL) in students with elevated anxiety sensitivity.

Residential posttraumatic stress disorder (PTSD) research in military samples generally shows that in aggregate, PTSD symptoms significantly improve over the course of treatment but can remain at elevated levels following treatment. Identifying individuals who respond to residential treatment versus those who do not, including those who worsen, is critical given the extensive resources required for such programs. This study examined predictors of treatment response among 282 male service members who received treatment in a U.

Article Synopsis
  • - Experiential avoidance is when individuals tend to avoid unpleasant feelings or thoughts, which can contribute to mental health issues, but there's debate on whether this is a category (specific group) or a spectrum (continuum).
  • - The study aimed to clarify this by analyzing data from two independent samples using different statistical methods to look at the underlying structure of experiential avoidance.
  • - Results showed that experiential avoidance is dimensional, meaning it varies in intensity rather than fitting into distinct categories, which has important implications for both therapy and future research.

Purpose: Despite cancer survivors' frequent endorsement of anxiety symptoms, assessing the full range of anxiety disorders (AD), their timing of onset relative to cancer diagnosis, co-morbidity with mood disorder, and predictors of post-cancer onset, is rare or absent to date. This study provides a step toward addressing these gaps.

Methods: Cancer survivors at re-entry after primary treatment completion who screened positively for anxiety symptoms (N = 133) and sought care through an intervention trial completed standardized diagnostic interviews, dimensional assessment of disorder severity, and timing of disorder onset relative to cancer diagnosis.

Background: Safety behaviours are ubiquitous across anxiety disorders and are associated with the aetiology, maintenance and exacerbation of anxiety. Cognitive behavioural models posit that beliefs about safety behaviours directly influence their use. Therefore, beliefs about safety behaviours may be an important component in decreasing safety behaviour use.

Avoidance has long been viewed as an etiological mechanism of anxiety disorders. Of more recent focus within this literature is the distinction between avoidance that is trait-based (experiential avoidance) versus contextual (safety behaviors). Whereas both experiential avoidance and safety behaviors have been studied within anxiety research, no known studies have evaluated the direct and indirect relationships of these forms of avoidance in predicting critical outcomes, particularly in conjunction with symptom severity.

School mental health (SMH) programs have been shown to be effective in providing evidence-based interventions to underserved youth. However, limitations of SMH programs are that they can entail holiday breaks, typically do not operate through summer, and often require pulling students from class to receive therapy. These limitations suggest that treatment must be expeditious and potent.

Objective: Cancer survivor preferences for formal interventions designed to provide psychological support remain relatively unknown. To address this gap, we evaluated cancer survivors' preferences for psychological intervention, whom they preferred to recommend such intervention, and how their preferences compared with what they currently received.

Methods: US cancer survivors (n = 345) who were at least 2 months post-treatment for diverse forms of cancer were recruited online to complete a survey study.

Most conceptualizations of evidence-based practice view it as a "three legged stool" consisting of: the use of best available research evidence, clinical expertise, and client preferences. Although empirical evidence and clinical expertise have received greater empirical attention, relatively little research has systematically explored client preferences. The present study analyzed self-reported treatment preferences for various clinical and non-clinical presentations.
