Acceptance and Commitment Therapy (ACT)

Psychoeducation OTHER

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
