At the Center for Psychosocial Research in GI (CPRGI), we seek to understand health behaviors that directly interfere with the effectiveness of medical care.

Health Behaviors?

These behaviors can be intentional or unintentional, and might include poor stress response, or inadequate sleep hygiene or diet. Other behavioral factors include low levels of physical activity, smoking, nonadherence to medication and/or dietary regimes, poor patient-physician communication, low social support, limited disease knowledge, caregiver stress, and psychological issues such as depression or anxiety.



Housed within the Division of Gastroenterology at Northwestern University Feinberg School of Medicine, we conduct psychosocial research and assessment in gastrointestinal diseases, adjustment to diagnosis, and nutrition and eating behaviors.

What’s the Connection?

The psychological and social aspects of GI diseases are often neglected in a busy health care setting. However, research shows that attending to a patient’s psychosocial needs in the context of a medical condition is critical for optimal disease care.



By participating in research, patients contribute to the advancement of science and help others cope with their disease.
