Randomized Controlled Trial
Internet-delivered exposure and mindfulness based therapy for irritable bowel syndrome--a randomized controlled trial.
The aim of this study was to investigate if cognitive behavior therapy (CBT) based on exposure and mindfulness exercises delivered via the Internet would be effective in treating participants with irritable bowel syndrome (IBS). Participants were recruited through self-referral. Eighty-six participants were included in the study and randomized to treatment or control condition (an online discussion forum). ⋯ Participants in the treatment condition reported a 42% decrease and participants in the control group reported a 12% increase in primary IBS-symptoms. Compared to the control condition, participants in the treatment group improved on all secondary outcome measures with a large between group effect size on quality of life (Cohen's d = 1.21). We conclude that CBT-based on exposure and mindfulness delivered via the Internet can be effective in treating IBS-patients, alleviating the total burden of symptoms and increasing quality of life.

Mindfulness forms the basis for multiple clinical interventions and has been induced in laboratory settings. However, few studies have examined the effects of dispositional or trait mindfulness. The purpose of this study was to investigate the relationship of trait mindfulness to laboratory stressor responding across fear-based anxiety disorder and non-anxious samples. We hypothesized that trait mindfulness would be associated with diminished stressor responding above and beyond the contribution of anxiety and depression-related variables, and to a greater extent in high anxiety than low anxiety individuals. ⋯ Trait mindfulness was associated with diminished responses to laboratory stressors in clinically anxious and non-anxious samples. Implications for emotion regulation and clinical interventions are discussed.
