About this study

Official title: Internet-delivered Psychological Treatment of Functional Gastrointestinal Disorders - A Danish Feasibility Study

Brief Summary

Functional gastrointestinal disorders (FGID), including irritable bowel syndrome (IBS), are common conditions characterized by recurrent gastrointestinal symptoms that cannot be fully explained by structural disease. FGID are associated with reduced quality of life, functional impairment, psychiatric comorbidity, and high healthcare utilization. Psychological interventions, particularly cognitive behavioral therapy (CBT), have demonstrated beneficial effects in FGID, but access to specialized treatment remains limited.

Read more

This study aims to evaluate the feasibility, acceptability, and potential clinical effects of a Danish exposure-based internet-delivered cognitive behavioral therapy (iCBT) program for adults with FGID. The intervention has been translated and culturally adapted from a Swedish program with previously documented efficacy.

In this single-arm feasibility study, 30 adults with FGID will complete a 10-week therapist-supported iCBT program consisting of psychoeducation, symptom monitoring, identification of avoidance behaviors, exposure exercises, and relapse prevention strategies. Participants will receive asynchronous weekly written support from trained CBT therapists.

Feasibility outcomes include treatment adherence and completion, participant satisfaction, treatment credibility, working alliance, adverse effects, and acceptability of the internet platform. Clinical outcomes include gastrointestinal symptom severity and quality of life, alongside measures of illness perceptions, illness worry, emotional distress, behavioral responses, functional symptoms, and spontaneous cognition during rest. Assessments will be conducted at baseline, post-treatment, and 3-month follow-up.

The study is conducted in Denmark as part of The Danish FGID Treatment Study through collaboration between Aarhus University Hospital, Regional Hospital Silkeborg, Aarhus University, and Karolinska Institute, Sweden. The findings will inform the future implementation and evaluation of internet-delivered psychological treatment for Danish patients with FGID.

Read the detailed description

OBJECTIVE: To test the feasibility of an exposure-based internet-based cognitive behavioral therapy (ICBT) treatment not previously evaluated in Denmark for adults with FGID in a Danish clinical context.

DESIGN: This is a feasibility study testing a of an exposure-based I-CBT treatment for FGID not previously evaluated in Denmark.

PARTICIPANTS: 30 adults with functional gastrointestinal disorder

PROJECT GROUP: Lisbeth Frostholm (Principal Investigator); Charlotte Ulrikka Rask (Principal Investigator); Karen Hansen Kallesøe; Heidi Frølund Pedersen; Lotte Fynne; Lise Gormsen (FL); Laura Krogsgaard (FL). Brjann Ljötsson, Erik Hedman

The Danish FGID Treatment Study is a joint cooperation between Regional Hospital Silkeborg, Department of Functional Disorders (FL), Aarhus University Hospital, the Research Unit at the Department of Child and Adolescent Psychiatry (BUA), Aarhus University Hospital, the Department of Clinical Medicine (CM), Aarhus University, and the Department of Clinical Neuroscience (CNS) at the Karolinska Institute in Stockholm, Sweden.

The trial will be conducted by the research group at the Dept. of Functional Disorders (www.functionaldisorders.dk), based at Aarhus University Hospital, Denmark. The clinic was established in 1999 and offers assessment and specialized treatment to patients with severe FSD. Patients are recruited from Regional Hospital Silkeborg

MAIN HYPOTHESIS: The feasibility of the I-CBT program will be assessed positively by the patients. At least 70% of included patients will complete the treatment. Furthermore, the I-CBT program will reduce symptoms of FGID and increase quality of life in patients with FGID.

INTERVENTION: The i-CBT program build on exposure based therapy and consists of 5 modules and takes 10 weeks to complete. The participants will be expected to use approximately 4 hours per week on the treatment. Asynchronous written support will be provided by a therapist on a weekly basis.

MEASUREMENTS: Self-reported measures will be administered to patients at several timepoints during the course of treatment, including before the start of the program (baseline, 0 weeks), after treatment (10 weeks), at the 3-month follow-up (22 weeks, primary endpoint), Beyond this, patients will receive a short daily questionnaire 5 times a day for 2 week (week 2 and week 8 into treatment)

Furthermore, therapist will evaluate patients' progress post-treatment (after 10 weeks). Therapists will record number and time usage of telephone/video consultations throughout the treatment. The treatment program will continually log the participants' data during the treatment period.

For a detailed list of the measures and measurement time points included, see the section "Outcome measures".

ANALYSIS: Data will be presented and analyzed according to current guidelines for feasibility studies

ETHICAL CONSIDERATIONS: The fesibility study presents low risks (side-effects and/or disadvantages) for the patients who may end their participation at any time point and can get into contact with a physician if their physical/mental health state deteriorates significantly. After patients have reached their final end-point, at the 3-month follow-up, they will be invited to a follow-up consultation with a medical doctor where their health/mental status will be assessed, and the need for further treatment discussed.

A study protocol has been approved by the Research Ethics Board of Aarhus University Hospital for approval (case.nr. 1-10-72-127-25). A pre-registration of the study has been submitted to ClinicalTrials.gov before the onset of the feasibility study. Data will be handled according to Danish law on the Data Protection Act and the Data Protection Regulation, and have been approved by the Danish Data Protection Agency (case.nr. 772917).
