Use of Cognitive Behavioral Therapy (CBT) or Sudarshan Kriya Yoga (SKY) for the Treatment of Anxiety and/or Depression in Inflammatory Bowel Disease (IBD)

Study Purpose

This is a prospective, single center, randomized treatment study to assess if anxiety and depression in participants with IBD can be improved with CBT compared to those treated with SKY.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

More Inclusion & Exclusion Criteria

Inclusion Criteria:

  • - verified Crohn's disease.
  • - Crohn's patients on a stable treatment regimen with no evidence of active intestinal inflammation based on either normal c-reactive protein and/or fecal calprotectin, imaging studies, or endoscopy who meet the criteria for anxiety or depression based on the screening questionnaires.
  • - subjects who have been on stable doses of anxiety and/or depression medications (defined as no dose adjustment in the prior 12 weeks) at the screening visit who meet the criteria for anxiety and/or depression based on screening questionnaires and are willing to stay on the same dose of these medications throughout the study duration.
  • - may meet the criteria for both anxiety and depression and cohort assignment will be based on the survey with the highest scores suggesting more severe symptoms.

Exclusion Criteria:

  • - declines to participate for the full duration of the study.
  • - evidence of active intestinal inflammation based on an elevated c-reactive protein and/or fecal calprotectin, imaging studies or endoscopy.

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

This is a prospective, single center, randomized treatment study, where participants will be screened for anxiety and depression in a Crohn's disease population using the Generalized Anxiety Disorder (GAD) questionnaire and the Patient Health Questionnaire (PHQ). Participants with GAD scores of ≥8 will be considered to have anxiety and those with a PHQ score of ≥10 will be considered to have depression. All participants with screening questionnaire scores positive for anxiety or depression will be randomized to treatment with either cognitive behavioral therapy (CBT) or Sudarshan Kriya Yoga (SKY). Screening with GAD and PHQ will be repeated post treatment at weeks 6, 12 and 24. The primary objective of this study is to assess for an improvement in GAD and PHQ scores among subjects treated with CBT compared to those treated with SKY. The secondary objectives are to assess for improvements in health-related quality of life, based on short IBD Questionnaire scores; assess for improvement in pain scores, based on the Brief Pain Inventory Short Form; and assess for improvement in fatigue scores based on the FACIT-Fatigue Scale, among subjects with poor scores at baseline following treatment with CBT or SKY.

Arms & Interventions


Active Comparator: Cognitive Behavioral Therapy

Participants in this arm will participate in CBT to assess the impact it will have on anxiety or depression among patients with Crohn's disease

Experimental: Sudarshan Kriya Yoga

Participants in this arm will participate in SKY to assess the impact it will have on anxiety or depression among patients with Crohn's disease


Behavioral: - Cognitive Behavioral Therapy

CBT is a combined psycho-social intervention that aims to improve overall mental health focusing on developing coping strategies. standard CBT Participants will have individual weekly sessions lasting 60 minutes each over an 8-week period with 1 follow-up maintenance session at week 12.

Behavioral: - Sudarshan Kriya Yoga

Participants will first attend a 3-day online workshop (2.5 hours each day) delivered live by a certified instructor to learn the SKY Breath Meditation practice. Participants will then practice SKY 25 minutes daily for 6 weeks and 3-4 times per week up to 12 weeks.
