About this study
Official title: Development, Feasibility, Efficacy, and Cost-effectiveness of an Online ACT Intervention for Disorders of Gut-Brain Interaction (Substudy 2)
The goal of this clinical trial is to assess the acceptability, feasibility, and usability of the iACTforDGBI intervention among patients with Disorders of Gut-Brain Interaction (DGBI). The main question it aims to answer are:
What are the perceptions of patients with DGBI and healthcare practitioners regarding the acceptability, feasibility, and usability of the iACTforDGBI intervention?
Participants will be asked to:
Complete the iACTforDGBI intervention prototype, consisting of self-guided online sessions.
Participate in online interviews and fill out online questionnaires to evaluate the intervention concerning acceptability, feasibility, usability and preliminary effects.
- Conditions
- DGBI, Depression/Anxiety
- Being tested
- Acceptance and Commitment Therapy (ACT), Psychoeducation
- Medical subject headings
- Depression, Anxiety Disorders
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Acceptance and Commitment Therapy (ACT)Behavioural
The self-guided Online version of Acceptance and Commitment Therapy (iACTforDGBI) intervention will include 8 weekly sessions of around 20 minutes each, and will comprise ACT-consistent informative texts, audio exercises, and videos.
The intervention is expected to have the following overall structure: Session 1: Introduction to the intervention and promotion of creative hopelessness, Awareness of bodily sensations, Values clarification Session 2: Committed action, Acceptance, Cognitive defusion Session 3: Self as context, Conclusions Session 4-8: personalised content (in-depth material and tasks based on individual difficulties assessed with diary)
PsychoeducationOther
Participants in the active control group will be asked to complete 8 weekly 20-minute sessions of an online course for education on DGBIs. This course will be delivered through a similar platform than the one delivering the online ACT for DGBI intervention, via the same website. The intervention platform will have similar designs and structure, and will be developed by the same web development company.
The content of the education course will be based on the IBS school intervention (e.g., Ringström et al., 2009), in particular its online version (Lindfors et al., 2021), developed by members of the current research team. This education intervention was based on the biopsychosocial model of DGBI and was originally developed and tested as a face-to-face group intervention with six 2-h sessions held weekly. IBS school generally aims at increasing disease knowledge in people with IBS and covers a wide spectrum of issues related to IBS, such as disease pathophysiological me
