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.

Background: While exposure therapy effectively reduces anxiety associated with specific phobias, not all individuals respond to treatment and some will experience a return of fear after treatment ceases.

Aims: This study aimed to test the potential benefit of increasing the intensity of exposure therapy by adding an extra step that challenged uncontrollability (Step 15: allowing a spider to walk freely over one's body) to the standard fear hierarchy.

Method: Fifty-one participants who had a severe fear of spiders completed two 60-min exposure sessions 1 week apart in a context that was either the same or different from the baseline and follow-up assessment context.

Behavior performed by parents to assist a youth in avoiding or alleviating anxiety, known as accommodation, is ubiquitous among pediatric anxiety disorders and strongly related to poor treatment outcome. According to cognitive-behavioral theory, the beliefs parents hold regarding accommodation should predict parental accommodating behavior. Unfortunately, little is known about the beliefs parents hold regarding accommodation, as there exists no validated measure of this construct.

Exposure therapy is a highly effective, evidence-based treatment technique for children and adolescents with anxiety disorders. Regardless, therapists in the community are reported to use exposure relatively rarely compared with other approaches. The goal of the present study was to identify how practicing clinicians treat youth with anxiety disorders across the United States and what factors contribute to their use of exposure therapy.

Owing to concerns about the safety and tolerability of exposure therapy, many clinicians deliver the treatment in an overly cautious manner, which may limit its effectiveness. Although didactic training in exposure reduces clinician concerns about the treatment to a moderate extent, improved training strategies are needed to minimize these concerns and improve exposure delivery. The present study compared the effectiveness of a standard (i.

Although client preferences are an integral component of evidence-based practice in psychology (American Psychological Association, 2006), relatively little research has examined what potential mental health consumers value in the psychotherapy they may receive. The present study was conducted to examine community members' preferences for the scientific and relational aspects of psychotherapy for different types of presenting problems, and how accurately therapists perceive these preferences. Community members (n = 200) were surveyed about the importance of scientific (e.

Objective: Little is understood about how the public perceives exposure-based therapy (ET) for treating anxiety and trauma-related disorders or how ET rationales affect treatment credibility. Distinct approaches to framing ET are practiced, including those emphasized in traditional cognitive behavioral therapy, acceptance and commitment therapy, and the more recent inhibitory learning model. However, their relative effect on ET's credibility remains unknown.

Individuals with social anxiety disorder (SAD) commonly experience panic attacks and evidence increased anxiety sensitivity (AS) specific to noticeable anxiety sensations. Interoceptive exposure (IE) is an effective treatment for reducing AS, but few IE tasks target fears of blushing, sweating, or trembling, which are incorporated within AS social concerns and especially feared by individuals with SAD. The primary study aims were trifold: (1) identify novel IE tasks that produce blushing, sweating, and/or trembling; (2) assess the intensity of sensations and anxiety produced by a series of novel and validated IE tasks; and (3) evaluate the incremental validity of combining an IE task and a speech task.

Intolerance of uncertainty (IU) is a construct of growing prominence in literature on anxiety disorders and major depressive disorder. Existing measures of IU do not define the uncertainty that respondents perceive as distressing. To address this limitation, we developed eight scales measuring disorder-specific intolerance of uncertainty (DSIU) relating to various anxiety disorders and major depressive disorder.

Ninety-two young adults were randomly assigned to watch two episodes of , a reality television program depicting the treatment of obsessive-compulsive disorder using exposure therapy, or two episodes of another reality television program (). Participants in condition ( = 35) endorsed significantly fewer negative beliefs about exposure therapy than participants in the condition ( = 42). Participants' obsessive-compulsive disorder symptoms did not moderate the beneficial effects of watching These results provide preliminary evidence that reality television programs can have a modest psychoeducational benefit and might be used to change attitudes about mental health problems and their treatment.

Although the chemical imbalance theory is the dominant causal explanation of depression in the United States, little is known about the effects of this explanation on depressed individuals. This experiment examined the impact of chemical imbalance test feedback on perceptions of stigma, prognosis, negative mood regulation expectancies, and treatment credibility and expectancy. Participants endorsing a past or current depressive episode received results of a bogus but credible biological test demonstrating their depressive symptoms to be caused, or not caused, by a chemical imbalance in the brain.

Analogue samples are often used to study obsessive-compulsive (OC) symptoms and related phenomena. This approach is based on the hypothesis that results derived from such samples are relevant to understanding OC symptoms in individuals with a diagnosis of obsessive-compulsive disorder (OCD). Two decades ago, Gibbs (1996) reviewed the available literature and found initial support for this hypothesis.

Despite research demonstrating the effectiveness of exposure therapy for pathological anxiety, this treatment is underutilized by clinicians. Anecdotal evidence and clinical experience suggest that therapists who possess reservations about exposure therapy tend to exclude clients from this treatment based on client characteristics believed to predict worse response. When exceptions are made based on characteristics that do not reliably predict poor outcomes, clients face the opportunity cost associated with investment in less effective treatments.

Unlabelled: Effective exposure therapies for anxiety disorders have been available for half a century. Over that time we have made great strides increasing the potency of these powerful methods. Yet, most of us in practice still have a conversation like the following with our new patients: Therapist: "So what treatments have you had for your anxiety symptoms to date?"

Patient: "I have seen numerous therapists over the last 10 years.

Despite the well-established efficacy of exposure therapy in the treatment of pathological anxiety, many therapists believe this treatment carries an unacceptably high risk for harm, is intolerable for patients, and poses a number of ethical quandaries. These beliefs have been shown to account for two related problems: (a) underutilization of exposure therapy, and (b) overly cautious and suboptimal delivery the treatment, which likely attenuates treatment outcomes. At present, there is little guidance for those who train exposure therapists to address these concerns.

Emetophobia, also referred to as a specific phobia of vomiting, is a largely under-researched and poorly understood disorder with prevalence estimates of ranging between 1.7 and 3.1% for men and 6 and 7% for women (Hunter & Antony, 2009; Philips, 1985).

Cognitive-behavioral treatments for panic disorder (PD) emphasize interoceptive exposure (IE) to target anxiety sensitivity (AS) but vary considerably in its manner of delivery. This randomized controlled trial was conducted to compare the efficacy of the low-dose delivery of IE exercises often prescribed in treatment protocols to an intensive form of IE hypothesized to optimize inhibitory learning. Participants (N = 120) with elevated AS were randomly assigned to one of four single-session interventions: (a) low-dose IE as prescribed in Barlow and Craske's Panic Control Treatment, (b) low-dose IE without controlled breathing or a lengthy between-trial rest period, (c) intensive IE, or (d) expressive writing control.

Exposure therapy is underutilized in the treatment of pathological anxiety and is often delivered in a suboptimal manner. Negative beliefs about exposure appear common among therapists and may pose a barrier to its dissemination. To permit reliable and valid assessment of such beliefs, we constructed the 21-item Therapist Beliefs about Exposure Scale (TBES) and examined its reliability and validity in three samples of practicing clinicians.

The biomedical model posits that mental disorders are brain diseases and emphasizes pharmacological treatment to target presumed biological abnormalities. A biologically-focused approach to science, policy, and practice has dominated the American healthcare system for more than three decades. During this time, the use of psychiatric medications has sharply increased and mental disorders have become commonly regarded as brain diseases caused by chemical imbalances that are corrected with disease-specific drugs.

Despite its effectiveness, exposure therapy is underutilized and frequently implemented in suboptimal fashion. Research has shown negative beliefs about exposure are related to its underutilization, and these beliefs are held by exposure therapists and may play a causal role in its suboptimal delivery. This study examined the effect of negative beliefs about exposure on treatment delivery.
