Psychological Therapies and Functional Bowel Disorders

December 20, 2019

Overview

This study aims to investigate how psychological therapies affect people with functional bowel disorders like irritable bowel syndrome (IBS.) Participants will be asked to complete 6 survey-based online questionnaires and then undergo a 12 week therapy program aimed at improving bowel symptoms and quality of life. Investigators will look at prevalence of post-traumatic stress disorder (PTSD) in patients with constipation symptoms.

 

Study Information

The study consists of various visits starting with going to an initial screening at a local GI office for an exam and questionnaire. Participants will then record stool symptoms and patterns in a diary for 15 days. Following this, participants will have 60-minute regular sessions with a GI psychologist once a week for 10-12 weeks and learn relaxation techniques and given assignments to monitor progress. After this period, participants will be asked to fill out the same questionnaires from the beginning of the study. Investigators are looking for 370 participants. The study started on June 1, 2018 and is estimated to be completed by August 31, 2020.

 

Inclusion Criteria

 

The inclusion criteria differs based on the aims:

 

Aim 1:

 

  • Ages 18+
  • Patients with a history of constipation based on clinical evaluation undergoing diagnostic testing for dyssynergic defecation with anorectal manometry with balloon expulsion test

 

Aim 2:

 

  • Patients with a history of constipation with or without dyssynergic defecation and a positive history of EALs or PTSD, as identified in Aim 1 based on survey responses.
  • Any positive history regardless of symptom severity will be considered. Positive history will be defined by an ACE score of 1 or higher OR a provisional diagnosis of PTSD. A provisional PTSD diagnosis can be made by treating each PCL-5 item rated as 2 = “Moderately” or higher as a symptom endorsed. The diagnostic rule will require a rating of “moderate” for the following: 1 B item (questions 1-5), 1 C item (questions 6-7), 2 D items (questions 8-14), and 2 E items (questions 15-20).

For Aim 1, key exclusion criteria are:

 

  • Patients who are currently hospitalized
  • Patients who are unable to consent
