Other |
Change in C-reactive protein |
We will measure blood levels of C-reactive protein |
Baseline, 8 weeks, and 21 weeks |
|
Other |
Change in fecal calprotectin |
We will measure levels of fecal calprotectin via a stool sample. |
Baseline, 8 weeks, and 21 weeks |
|
Other |
Change in sleep architecture |
We will measure changes in percent time spent in light sleep, deep sleep, and rapid eye movement (REM) sleep using the Oura ring. |
Baseline, 8 weeks, and 21 weeks |
|
Other |
Change in behaviorally assessed pain tolerance via the Cold Pressor Test |
The Cold Pressor Test involves submerging one's non-dominant hand in ice water and rating discomfort at regular, pre-determined intervals. Pain tolerance will be measured based on the total amount of time a participant can keep their hand submerged, with a maximum of 3 minutes. |
Baseline, 8 weeks, and 21 weeks |
|
Other |
Change in diary-based sleep efficiency |
Change in sleep efficiency (total sleep time / time in bed), derived from a self-reported sleep diary. |
Baseline, 8 weeks, 21 weeks, and 34 weeks |
|
Other |
Change in objective sleep onset latency |
Change in the time it takes to fall asleep each night, derived from the Oura ring. |
Baseline, 8 weeks, and 21 weeks |
|
Other |
Change in objective wake after sleep onset |
Change in the time spent awake in the middle of the night, derived from the Oura ring. |
Baseline, 8 weeks, and 21 weeks |
|
Other |
Change in objective sleep efficiency |
Change in sleep efficiency (total sleep time / time in bed), derived from the Oura ring. |
Baseline, 8 weeks, and 21 weeks |
|
Primary |
Feasibility of the intervention as measured by attrition rate over time |
Attrition rate will be based on the percentage of participants who have dropped out of the trial at different time points. |
Baseline, 8 weeks, 21 weeks, and 34 weeks |
|
Primary |
Feasibility of the intervention as measured by recruitment rate over time |
Recruitment rate will be based on the number of participants who are recruited into the trial per month. |
From study initiation until we are no longer actively recruiting (approximately 24 months) |
|
Primary |
Feasibility of the intervention as measured by assessment completion at multiple time points |
Assessment completion rate will be based on the percentage of participants who complete all the required questionnaires and tasks at each time point. |
Baseline, 8 weeks, 21 weeks, and 34 weeks |
|
Primary |
Feasibility of the intervention as measured by qualitative interviews |
Feasibility will be based on interview-derived themes related to barriers and facilitators to study engagement. Data will be collected at two time points to ensure completeness of themes. |
8 weeks and 34 weeks |
|
Primary |
Acceptability of the intervention as measured by visit completion |
Visit completion will be based the number of visits (out of 5) completed by each participant. |
8 weeks |
|
Primary |
Treatment acceptability questionnaire score |
The Treatment Acceptability Questionnaire is a 4-item self-report questionnaire designed to assess the overall acceptability of an intervention. Scores range from 1 to 4 and higher scores are indicative of greater acceptability. |
1 week |
|
Primary |
Acceptability of the intervention as measured by qualitative interviews |
Acceptability will be based on interview-derived themes related to aspects of the intervention that participants found helpful and unhelpful. |
8 weeks |
|
Secondary |
Change in insomnia symptoms as measured by the Insomnia Severity Index |
The Insomnia Severity Index (ISI) is a self-report questionnaire designed to measure severity of insomnia. The ISI is made up of 7 items on insomnia symptoms and related impairments and total scores range from 0-28. Higher scores are indicative of greater insomnia symptoms. |
Baseline, 8 weeks, 21 weeks, and 34 weeks |
|
Secondary |
Change in diary-based sleep onset latency |
A weekly average of self-reported time it takes to fall asleep each night, derived from a self-reported sleep diary |
Baseline, 8 weeks, 21 weeks, and 34 weeks |
|
Secondary |
Change in diary-based wake after sleep onset |
A weekly average of self-reported time spent awake in the middle of each night, derived from a self-reported sleep diary |
Baseline, 8 weeks, 21 weeks, and 34 weeks |
|
Secondary |
Change in Crohn's disease symptoms as measured by the Patient Reported Outcomes 3 |
The Patient Reported Outcomes 3 (PRO-3) is a self-report questionnaire designed to measure the severity of Crohn's disease symptoms in the past week. The PRO-3 is made up of 3 items (stool frequency, pain, and well-being) and higher scores are indicative of more severe symptoms. Scores are interpreted as follows: <13=quiescent or inactive disease; 13-21=mildly active disease; 22-52=moderately active disease; 53 and up=severely active disease. |
Baseline, 8 weeks, 21 weeks, and 34 weeks |
