Electronic Food and Symptom Diaries are Feasible and Usable Data Collection Tools for IBS Patients
Dr. Jasmine Zia and colleagues report on their feasiblity study of a SmartPhone App as a symptom tracker for IBS patients in which they found at least one strong association between GI symptoms and a meal nutrient in 73% of participants. The investigators assessed feasibility and usability of a novel app in 11 IBS patients (8 women), aged 21–65 years. Participants were asked to log GI symptoms (abdominal pain, bloating, diarrhea, constipation) using a 100-point color-graded sliding scale (green=none, red=severe) four times a day and to log every meal/snack they ate (at least three times a day) over a 2-week period. 
The app’s user interface was based on journal templates from the book “Master your IBS: An 8-Week Plan to Control the Symptoms of Irritable Bowel Syndrome.”
