About this study

Official title: Cognitive Behavior Therapy vs. Behavioral Stress Management for Severe Health Anxiety: a Randomized Controlled Trial of Two Internet-based Treatments

Background

Severe health anxiety, hypochondriasis according to DSM-IV, is common and associated with functional disability. Cognitive behavior therapy (CBT) and behavioral stress management (BSM) have been showed to be effective in the treatment of severe health anxiety. The mechanisms of the treatments are however poorly understood. In addition, effective psychological treatments are accessible to only a few. One prior RCT has shown that internet-based CBT could be effective in comparison to waiting list controls. More studies on internet-based CBT is essential to establish evidence. In addition, few studies with sufficient power have investigated the effect of CBT in comparison to other active treatments.

Aim of the study The aim of the present RCT is to compare internet-based CBT (n=110) to behavioral stress management (n=110) for adult participants with severe health anxiety. BSM is considered a comparison treatment for two reasons: it has been shown to be effective and it lacks exposure and response prevention, which is suggested to be an important mechanism in CBT.

Participants in both treatments are expected to be significantly improved on measures of health anxiety. Participants receiving CBT are expected to be significantly more improved compared to participants receiving BSM.

Aim of the study The aim of the present RCT is to compare internet-based CBT (n=110) to behavioral stress management (n=110) for adult participants with severe health anxiety. BSM is considered a comparison treatment for two reasons: it has been shown to be effective and it lacks exposure and response prevention, which is suggested to be an important mechanism in CBT.

The investigators expect participants in both treatments to be significantly improved on measures of health anxiety. Participants receiving CBT are expected to be significantly more improved compared to participants receiving BSM.

Design:

Randomized controlled trial. Participants are randomized in a 1:1 ratio.

Assessments:

The primary outcome measure is the Health Anxiety Inventory (HAI). Assessments with HAI are conducted at baseline, post-treatment, 3- and 12 month follow-up.

Conditions
Hypochondriasis
Being tested
CBT, exposure and response prevention, BSM, stress management and applied relaxation

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CBT, exposure and response preventionBehavioural

    This intervention entails different exercises aimed exposure to health anxiety stimuli.

  • BSM, stress management and applied relaxationBehavioural

    BSM, this intervention comprises structured exercises aimed at reducing stress and controlling the anxiety response. One main component is applied relaxation.
