IBD-Sleep: A Pilot Study Looking at Changes in Sleep Timing and IBD Symptoms

April 23, 2026 updated by: Helen Burgess, University of Michigan
This research study is testing whether changes in sleep timing and morning light treatment may have an impact on symptoms related to inflammatory bowel disease.

Participants will not make modifications to their activities or sleep schedule.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Short IBD Questionnaire (SIBDQ) score
Time Frame: Baseline, post-treatment approximately 36 days
SIBDQ is 10 questions, each with a Likert like scale with 7 options and lower scores indicate poorer quality of life.
Baseline, post-treatment approximately 36 days

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Patient Health Questionnaire 9 (PHQ-9) score
Time Frame: Baseline, post-treatment approximately 36 days
PHQ-9 is a depression score ranging from 0 through 27. No depression 0-4, mild 5-9, moderate 10-14, moderately severe 15-19, severe 20-27.
Baseline, post-treatment approximately 36 days
Change in Patient-Reported Outcomes Measurement Information System Sleep Disturbance (PROMIS) Short-Form 8b
Time Frame: Baseline, post-treatment approximately 36 days
PROMIS Sleep Disturbance measures self-reported sleep quality during the past seven days. The measure includes 8-items with higher scores indicating greater sleep disturbance.
Baseline, post-treatment approximately 36 days
For patients with Crohn's Disease (CD) - Change in Harvey Bradshaw Index (HBI)
Time Frame: Baseline, post-treatment approximately 36 days
The HBI is a clinician-rated measure of disease severity in Crohn's disease (CD). The HBI has items addressing a range of symptoms including general well-being, abdominal pain, liquidity/softness of stool, presence of an abdominal mass and complications. The total score reflects the following: score <5 = remission, 5 to 7 = mild disease activity, 8 to 16 = moderate disease activity and >16 = severe disease activity.
Baseline, post-treatment approximately 36 days
For patients with Ulcerative Colitis (UC) - Change in Simple Clinical Colitis Activity Index (SCCAI)
Time Frame: Baseline, post-treatment approximately 36 days
The SCCAI is a clinician-rated measure of disease severity in ulcerative colitis (UC). The SCCAI has items addressing a range of symptoms from bowel frequency, defecation urgency, blood in stool, general well-being, and other extracolonic disease features. Scores range from 0 to 19 points, and scores < or equal to 2.5 indicate clinical remission.
Baseline, post-treatment approximately 36 days
