About this study

Anxiety disorders are common pervasive conditions with serious psychosocial implications. Anxiety sensitivity (AS) is one individual characteristic that has been implicated in the onset and maintenance of anxiety disorders (Schmidt et al., 1999). AS is an enduring fear of anxiety-related arousal sensations (i.e., increased heart rate) that arises from the tendency to interpret these sensations catastrophically, believing that they will have serious physical, psychological, or social consequences (Reiss, 1991).

Research has shown the efficacy of CBT in decreasing AS among women with high AS (Watt et al., 2006). Unfortunately, access to effective psychological treatments is limited by a number of barriers such as a lack of treatment availability or qualified clinicians in an area. As such, we are conducting a randomized controlled trial (RCT) of the effectiveness of a distance-based CBT program on decreasing AS among those with high AS. A distance delivery approach (e.g., via telephone) is one way to minimize treatment barriers and increase access to care while still delivering empirically supported treatment. Recent research suggests distance delivery is promising (Lovell et al., 2006).

The RCT will consist of an eight-week structured CBT program based on Watt and Stewart's (2008) brief CBT for AS. The program will include weekly modules on psychoeducation, cognitive restructuring, interoceptive exposure, and relapse prevention. Participants with high AS will be recruited and randomly assigned to the treatment condition or wait-list control (after twelve weeks the wait-list group will receive treatment). In the treatment condition, participants will be assigned weekly reading and homework from the treatment manual. In addition, a therapist will guide them through the treatment by providing individualized support and feedback through weekly half-hour telephone sessions. Treatment outcomes will be assessed through changes in AS levels and anxiety symptoms pre- to post-treatment. Also, participants' satisfaction with the mode of treatment delivery will be assessed. We hypothesize that this treatment program will be effective in reducing high AS and anxiety symptom frequency and severity. We also expect this project to yield information about the utility of distance treatment delivery for mental health care.

Questions about this trial

What is this clinical trial studying?

A study testing Distance-based Cognitive Behavioural Therapy in people with Anxiety Sensitivity, run by Dalhousie University at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 22 Jan 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from Pre-Treatment in Anxiety Sensitivity Level at Post-Treatment (time frame: 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jan 2014.
