About this study

This study investigates the feasibility and preliminary efficacy of a self-guided, exposure-based intervention for individuals who suffer from severe health anxiety. The study is a prospective single-group study based at Karolinska Institutet, Stockholm, Sweden, where 20-25 adults with DSM-5 Illness anxiety disorder or Somatic symptom disorder are enrolled in 8 weeks of unguided exposure-based treatment via the Internet. Outcomes include self-reported health anxiety symptoms, credibility and expectancy, adherence to the treatment protocol, client satisfaction, and negative events.

Read the detailed description

Background

Severe health anxiety (Corresponding to a DSM-5-diagnosis of Illness anxiety disorder or somatic symptom disorder) is a condition associated with high distress, disability and increased health service utilization. Therapist guided Internet delivered cognitive behavioural therapy (ICBT) is efficacious in the treatment of severe health anxiety and has the advantage of requiring less treatment support per patient compared to traditional CBT, thus making the treatment more cost effective. Despite this, the access to ICBT is limited as it requires the active participation of a therapist. Given the relatively high prevalence of individuals experiencing excessive health anxiety, there is need for research on more accessible treatment options.

Unguided self-care interventions have the potential to improve access to treatment and increase cost-effectiveness and have a more immediate scalability. Also, unguided interventions have the advantage of being more easily disseminated outside the traditional mental health care systems and thus, have the potential to reach patients with subclinical, yet distressful, health anxiety.

Aim

The overall aim of this study is to develop a new internet-delivered CBT program based on exposure and response prevention - without therapist support - for patients with severe health anxiety and to examine its feasibility and potential clinical efficacy.

Design

This is a prospective single-group feasibility study with a pre-post design where a total of 25 participants with Illness anxiety disorder or Somatic symptom disorder (suffering from health anxiety) according to the Diagnostic and statistical manual of mental disorders 5 (DSM-5) are enrolled in an 8 weeks unguided internet based treatment targeting exposure and response prevention. The study will evaluate patient-reported satisfaction, engagement and adherence to treatment protocol, credibility, safety and pre-post changes in health anxiety.

What participants receive

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

  • Self-guided Exposure-based Digital Intervention for Health AnxietyBehavioural

    An 8-week self-guided internet based CBT intervention which consists of text, exercises, examples and automated support. The format, potentially more accessible compared to traditional ICBT, will be developed with the aim to enhance treatment comprehension and motivation in the participants. The program consists of eight modules (chapters) where the main therapeutic focus is exposure with response prevention.

    Participant will be interviewed before the program starts, after 8 weeks and 3 months after the program ends. If in need for technical support, participant will be able to ask for assistance via the program and will then be contacted by a clinician via telephone within a couple of days.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Health anxiety symptoms

    The Short health anxiety inventory - 14 item (SHAI-14). Higher scores indicate greater severity of health anxiety. Scores range from 0 to 42.

    Measured: pre-treatment assessment to 12 weeks after post-treatment assessment

  2. Adherence to the treatment: amount of exposures

    Will be determined by the amount of exposure exercises reported in the program and in a weekly questionnaire. Acceptable level of adherence will be set to at least 50 % of participants working actively with exposure a majority of the days during a week for 4 weeks or more.

    Measured: Post-treatment assessment (immediately after treatment)

  3. Adherence to the treatment: number of modules

    Will be determined by the number of modules completed by the participants.

    Measured: Post-treatment assessment (immediately after treatment)

  4. Adherence to the treatment: types of exposure

    Will be determined by the number of different types of exposure exercises performed by participants. At the end of the program, participants will answer yes or no to whether they engaged in each component (type of exposure exercise) of the intervention.

    Measured: Post-treatment assessment (immediately after treatment)

  5. Unintended treatment effects

    Participants will be asked to state whether they had experienced any negative or unwanted effects of the treatment. If answering 'Yes', participants will be asked to specify the adverse event in free text. Adverse events will primarily be reported as the total number of reported events.

    Measured: Post-treatment assessment (immediately after treatment)

  6. Satisfaction with treatment

    Client Satisfaction Questionnaire (CSQ-8). Scores range from 8-32 with higher scores indicating greater satisfaction. An average Client Satisfaction Questionnaire-8 score of at least 22 will provide support for the acceptability and feasibility of this intervention.

    Measured: Post-treatment assessment (immediately after treatment)

Secondary outcomes (15)
