IBstressD: The effect of Acceptance and Commitment Therapy (ACT) on stress reduction in Inflammatory Bowel Disease (A pilot study)

This pilot study assessed the feasibility of Acceptance and Commitment Therapy (ACT), delivered through a smartphone app, Psychflex, for reducing stress in patients with Inflammatory Bowel Disease (IBD). Considering the significant burden posed by IBD to physical and psychological functioning and the prevalence of comorbid stress as a potential contributor to disease activity, the inclusion of psychological interventions in the treatment process has become increasingly important.

This study uses a Single-Case Experimental Design with three individuals diagnosed with IBD who were experiencing moderate to severe IBD-related stress. Over a period of 25 days, participants were exposed to ACT content daily via Psychflex, a smartphone application, which also measured the level of reported stress using a standardised likert-based stress scale at baseline and post-intervention.

These results show a significant decrease in the stress levels of all participants.

According to the statistical analyses, improvements in stress happened consistently, with a median stress reduction of −2, which is p < .0001.

Despite difficulties regarding participant recruitment and sample size, the results tentatively show that ACT delivered via a smartphone might prove to be an effective supplementary treatment for IBD patients. These findings give credence to the potential of digital interventions for facilitating greater accessibility to treatment and day-to-day management of chronic health conditions. Future research could study the effect across multiple hospitals and contexts.
