Brief summary

Stress is a well-established trigger for exacerbation of IBS symptoms. This study aims to evaluate the effects of a stress mindset intervention on perceived stress, gastrointestinal symptom-specific anxiety, and IBS symptom severity, compared to standard stress management information. After completing the baseline measures, participants will be randomly assigned by the Qualtrics survey platform to one of two groups in a 1:1 ratio. Participants in the mindset group will watch a video series designed to change how people think about stress by explaining how stress responses can sometimes be helpful and manageable. Participants in the standard information group will watch a video series that provides typical information about stress but does not attempt to change beliefs about stress. Immediately after watching the video series, participants will complete a second online questionnaire assessing stress beliefs, anxiety, and IBS symptoms. One month after the intervention, participants will receive an email with a link to complete the final follow-up questionnaire, which will assess the same outcomes.

Interventions

This study is investigating a stress mindset intervention, which helps patients understand that stress can also be helpful and enhancing to life. The intervention is called Rethink Stress, which was developed and validated by the Mind & Body Lab at Stanford University (see Crum et al., 2013). The intervention was not developed for this study. Rethink Stress is an approximate hour-long online course split into 7 modules: - The role stress plays in our lives - The science of stress - The power
