The study aims to compare the effect of mindfulness-based awareness training in Irritable Bowel Syndrome (IBS) (MB-IBS-EAT) with the dietary standard of care (low fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAP) diet) on patient's IBS symptoms
This pilot study will be a randomized parallel trial comparing MB-IBS-EAT done over an 8-week period to a standard low FODMAP diet. The low FODMAP diet is currently employed by clinicians as a treatment for IBS, but response rates are poor, without documented long-term benefit. This finding supports the need for better, longer lasting interventions.

| Change in Perceived Stress Level (PSS) Scores | Individual scores on the PSS can range from 0 to 40 with higher scores indicating higher perceived stress. Scores ranging from 0-13 would be considered low stress. Scores ranging from 14-26 would be considered moderate stress. Scores ranging from 27-40 would be considered high perceived stress | Baseline, Week 1, Week 4, Week 8, and Week 12 |

| Change in Five Factor Mindfulness Questionnaire (5FMQ) Scores | 39-question measure that assesses trait mindfulness. In addition to the total score, there are five subscales: Non-judgement, Non-reaction, Describe, Observe, and Act with Awareness - Average scores are calculated by summing the responses and dividing by the number of items, and indicate the average level of agreement with the each subscale (1 = rarely true, 5 = always true). Higher scores are indicative of someone who is more mindful in their everyday life | Baseline, Week 4, Week 8, and Week 12 |
| Change in Mindful Eating Questionnaire (MEQ) Scores | 28-question measure that assesses eating habits and mental tendencies while eating - Scoring. Each item was scored from 1 to 4, where higher scores signified more mindful eating. Each subscale score was calculated as the mean of items, excluding those with a "not-applicable" response. The summary score was the mean of the 5 subscales | Baseline, Week 8, and week 12 |
| Change in Positive and Negative Affect Schedule (PANAS_State) Questionnaire Scores | 20-question measure that assesses the degree to which positive and negative emotions are currently being felt - Positive Affect Score: Add the scores on items 1, 3, 5, 9, 10, 12, 14, 16, 17, and 19. Scores can range from 10 - 50, with higher scores representing higher levels of positive affect - Mean Scores: 33.3 (SD±7.2) Negative Affect Score: Add the scores on items 2, 4, 6, 7, 8, 11, 13, 15, 18, and 20. Scores can range from 10 - 50, with lower scores representing lower levels of negative affect - Mean Score: 17.4 (SD ± 6.2) | Baseline, Week 8, and Week 12 |
| Change in cortisol blood levels | differences in cortisol levels | Baseline and Week 8 |
| Change in cytokine blood levels | differences in cytokine levels - cytokine levels drawn at 8 am at screening or baseline if patient agrees - The detection of intracellular cytokines is a relatively new technique in which cells are permeabilized and antibodies are used to detect cytokine protein within cells by flow cytometry - when too many cytokines are released, it can cause your immune system to go into overdrive | Baseline and Week 8 |
| Change in serotonin blood levels | differences in serotonin levels | Baseline and Week 8 |
| Change in Irritable Bowel Syndrome Quality of Life (IBS-QOL) Scores | The individual responses to the 34 items are summed and averaged for a total score and then transformed to a 0-100 scale for ease of interpretation with higher scores indicating better IBS specific quality of life. | Baseline, Week 4, Week 8, and Week 12 |
| Change in Hospital Anxiety and Depression Scale (HADS) Scores | The HADS questionnaire has seven items each for depression and anxiety subscales. Scoring for each item ranges from zero to three, with three denoting highest anxiety or depression level. A total subscale score of >8 points out of a possible 21 denotes considerable symptoms of anxiety or depression | Baseline, Week 1, Week 4, Week 8, and Week 12 |
| Change in Irritable bowel syndrome symptom severity (IBS-SSS) Scores | IBS-SSS is a composite score of abdominal pain, number of days with abdominal pain, bloating/distension, satisfaction with bowel habits, and IBS-related quality of life (QoL). Each measure is rated from 0 to 100, with total scores ranging from 0 to 500 - Mild, moderate and severe cases were indicated by scores of 75 to 175, 175 to 300 and > 300 | Baseline, Week 1, Week 4, Week 8, and Week 12 |
| Gastroparesis Cardinal Symptom Index (GCSI) Scores | The GCSI total score is constructed as the average of the three symptom subscales. GCSI total score can range from 0 to 5, with higher scores reflecting greater symptom severity | Baseline, Week 1, Week 4, Week 8, and Week 12 |
