Detailed Description

Irritable bowel syndrome (IBS) is defined as having recurrent abdominal pain associated with defecation or a change of bowel habits. The pathophysiology of IBS can be looked through the biopsychosocial model of disease which is defined by the complex interplay between genetic, cultural, environmental, and psychosocial factors.

Treatment of IBS is multifaceted and ranges from exercise to dietary restrictions, however, psychological treatments to target the gut-brain axis such as cognitive-behavior therapy (CBT) have also been shown to be an effective therapy, and aims to address the psychological and environmental stressors that contribute to the symptoms. Therefore the purpose of the study is investigate the effectiveness of Zemedy, a mobile application that enables the digital delivery of a CBT program to people with IBS.

CBT has been shown to reduce the severity of intractable IBS symptoms by as much as 70%. The investigators hope to learn whether the Zemedy mobile application is effective in the reduction of IBS. This will be measured based on their IBS Symptom Severity Scores (SSS) at week 8 compared to baseline.

Arms and Interventions

Arm	Intervention/Treatment
No Intervention: Control Group (TAU only) Treatment as Usual (TAU) for IBS patients are tailored to each individual's needs and may involve treatment such as: dietary modification, exercise, medication, and anti-diarrheal therapy.
Experimental: Experimental (TAU plus CBT) Subjects who are in the Experimental Group will receive 8 weeks of CBT from the Zemedy mobile application in addition to their treatment as usual (TAU).	Device: Use of Zemedy Application; 8 weeks of CBT via the Zemedy Application.

Outcome Measures

Primary Outcome Measures

1. IBS-SSS at 8 Weeks [Baseline and at Week 8.]

   Change in IBS symptoms based on the change in IBS symptom severity score (IBS-SSS) score at week 8 compared to baseline. Score range: 0-500

Secondary Outcome Measures

1. IBS-SSS at 24 Weeks [Baseline and at Week 24.]

   Change in IBS symptoms based on the change in IBS symptom severity score (IBS-SSS) score at week 24 compared to baseline. Score range: 0-500
